How long does it take for bitumen mastic to dry?

The time after which the working surface treated with mastic is ready for full use depends on various conditions that, one way or another, affect the drying of bitumen mastic. The drying speed of the mastic also differs significantly depending on the various additives and bases for its production.

It is necessary to list those external factors, the independent influence of which influence how long it takes bitumen mastic to dry :

• Thickness of the layer of mastic applied to the treated surface;
• Ambient temperature and level of its fluctuations;
• Air humidity level;
• Presence or absence of exposure to direct sunlight;
• The type of material from which the treated surfaces are made.

Hardening and the final consistency of the mastic depends on the rate of evaporation of the chemical solvent contained in this waterproofing material.

Manufacturers of construction bitumen mastics declare the average drying time from one to 3 days. Various technological features in the manufacture of this material affect this period.

What is bitumen mastic?

Understanding what bitumen mastic is is not very difficult. In simple terms, this is bitumen improved with the help of various additives. Due to these additives, the bitumen composition is resistant to cracks and is also thicker. Therefore, if the question arises of how to insulate the roof of a private house, do not forget to take into account the layer of bitumen mastic. If we talk about the appearance of this composition, it resembles a paste, deep black in color.

Despite the fact that this product appeared on the Russian market relatively recently, it quickly gained popularity. It is safe to say that at the moment bitumen mastic is one of the best-selling products in the field of building materials and roofing materials.

What is used for breeding?

Depending on where the material will be applied, the proportions and density are changed. Otherwise, the composition simply will not be able to stay on the surface before it dries completely. Mastics are different, which means the products for breeding will also be different.

Most often used to dilute materials:

• Motor gasoline or kerosene.
• White Spirit.
• Gasoline "Galosh".

In most cases, low-octane gasolines are used as diluents. The polymerization process of the dissolved composition takes 24 hours after application. This is provided that the work is performed outdoors.

As for the proportions, they must correspond to the volume of the base used. If you violate them, the mixture will dry out more slowly or the fluidity of the solution will increase. As a result, adhesion will decrease or beneficial properties will be lost. In this case, the material will not have protective functions.

How can you dilute rubber-bitumen mastic? There are other materials. This is turpentine, any types of organic solvents. It is not recommended to use acetone or liquids based on it for these purposes. Some craftsmen dissolve mastic in diesel fuel. As a result, the mixture turns out to be heterogeneous. However, this solution fills all cracks and irregularities with the highest quality possible. If the mastic is liquid, it has better adhesion and good insulating properties.

How to dilute bitumen mastic to a liquid state?

And now some useful tips for craftsmen on how to dilute bitumen mastic to a liquid state. As is known, according to its composition, bitumen mastic is divided into several types. Also, the material is also divided according to the method of application and technical characteristics.

Some types of mastic cannot be used in certain conditions, for example at very low temperatures. Also, if the mastic needs to be heated, then the temperature of the composition must be at least 160 degrees. Only after this can the products be used for work. If we talk about cold mixtures that can be used when installing PVC membrane roofing, the conditions of use will be different. The most important thing is not to heat it, use it in its original form.

Also, if you use cold mastic, it needs to be diluted. Concentrated material may thicken too much and play a cruel joke on you. But, the components for dilution depend on how the composition will be applied to a particular surface.

If you prefer to dilute any compositions with a solvent, then in the case of mastic we do not recommend doing this. Since the solvent tends to evaporate, therefore, when the mastic hardens, this is more likely to happen. By the way, when installing a membrane roof, the price of work per m2 is calculated together with the preparation of the consumables themselves.

Therefore, if you hire specialists to lay mastic, you don’t have to worry about what and how to dilute it. All this is done by masters. The best thinners are components such as:

• Kerosene;
• Petrol;
• Diesel fuel (diesel fuel).

All these substances have the property of “holding” their shape. That is, if the proportions are observed correctly, they will not curl up, evaporate, or change their technical qualities. In addition, they are easy to obtain on the market.

How to properly dry mastic products - tips

Comments on the entry "How to properly dry mastic products - tips"

Thank you very much to the author for such useful information, since I am just learning, these tips were very useful to me. If possible, please answer my question. How many days in advance to make cake figures? I want to make this for my daughter's birthday. But I'm afraid that if they sit there for a long time, they won't spoil. And if I make it and decorate it, where should I store it in the room or in the refrigerator? Thank you in advance))

Irina, in fact, such jewelry lasts a long time. Unused mastic can be kept in the refrigerator for 2 weeks or in the freezer for about a month, after wrapping it in cling film. Any figurines can be stored for several days, up to 10 days, in well-closed plastic bags or plastic containers. There is nothing to spoil in sugar mastic; it is important to simply protect the mastic from air so that it does not dry out and from moisture so that the mastic does not get wet.

Hello. I have this question: I want to make a cake decorated with fondant for my mother-in-law, but the problem is that we don’t live together, and I’ll be baking at home, what’s the best thing to do in this case with decorations if I decorate everything at home? , will he be able to wait until he gets to the table (about 20 minutes walk)?))))))

Anna, don’t worry, nothing will happen in this time. The only thing is to thoroughly dry the mastic decorations in advance so that they don’t “float” and everything will be great. You came up with a wonderful gift for your mother-in-law)

Hello. I have a question. Most often they order lady fingers cake from me, and of course they want a mastic decoration. but not just with sour cream, but with gelatin so that there is a shape, but the mastic (even dried) floats on the gelatin. please tell me how best I can do all this. I myself relatively recently (1 year) took up such a wonderful business and simply fell in love with it. thanks for the answer and for the advice.

Natalya, alas, such jelly cakes are just exceptions to mastic; the decorations still “float”. You can wrap the sponge cake in a thin layer, for example, so that there is a minimum of it, then cool the cake and then decorate it. There is no other way)

Hello! Tell me, please, if I need to make round decorations for cupcakes from fondant (I will place them on top of the cream), should I also store them at room temperature?? It’s just that I previously stored them in the refrigerator, and they “flowed” during transportation (the journey was 15 minutes maximum). I had cream from Philadelphia and butter. Thanks in advance for your answer!

Lena, in principle they shouldn’t have leaked in such a time, maybe you didn’t wait until they were completely dry? But, if you are worried, then as an option: store the cupcakes in the refrigerator, transport them separately from the decorations, and decorate your desserts with them on the spot, placing them on the cream.

Maybe.. But it’s still better to dry at room temperature, right?

I think yes, this will be the best option.

Tell me how to preserve the marzipan mastic figures that are left after the cake is eaten? This is a memory from my niece’s christening and we want the figurines (slippers and marzipan baby) to remain as a souvenir for a long time. I once was in the marzipan museum in Budapest, there are human-sized marzipan figures there. How do they store them?! So I’m wondering how to save mine))). Thank you. Elena

Lena, they should dry well, after which they can be stored for several months in a dry place, for example, you can put them on a shelf. But, depending on the mastic, they will begin to fall apart over time, although sometimes they stand perfectly well for two years.

If you don’t want it in a visible place, then figurines made from mastic are well stored in a tight box, which needs to be placed in a dry place. Instead of a box, you can use a plastic container, which needs to be placed in a dry place so that they dry well.

Tell me, please, I made mastics from marshmallows, I went too far with citric acid. Is it possible to somehow remove the sour taste? Thank you very much in advance

Ksyushka, it’s no longer possible to remove it. If the mastic doesn’t break and everything works out, then leave it like that. Next time make it less sour)

HELLO, I MADE A CROWN FROM MASTIC, IT TOOK 4 HOURS, I TRIED TO REMOVE IT AND IT BREAKS. WHAT TO DO. I DID NOT COVER IT WITH ANYTHING THIS IS MY FIRST WORK, I JUST ADDED DYE AND DID IT ON THE FRAME.

Marina, you definitely let the mastic decoration dry well. Maybe you were in a hurry? And you didn’t write what kind of mastic the crown was made of - sugar, marshmallow, milk or some other.

Hello, I was making poppy petals from sugar mastic, and since I needed a bright scarlet color, I had to add a lot of liquid coating agent, which made the mastic itself runny. I read that in this case you can thicken the mastic with powdered sugar, which is what I did. The petals turned out, but after a day they practically did not dry ((Please tell me, is there a chance in my case that the mastic will dry out? Or did I ruin it with dye and powder?

Julia, it is not advisable to use liquid food coloring, because... They change the consistency of the mastic; it will most likely become liquid and impossible to work with. That's what happened to you. But if the mastic is still liquid, then add more powdered sugar and starch, don’t be afraid to experiment, this is a sweet dough and it should resemble plasticine)

Thanks for the answer!

Good afternoon! I really need your advice, I will be grateful if you answer. I have no experience working with mastic, I have to bake a cake with mastic elements, namely, I transfer a design on sugar paper onto 3mm wide mastic, then decorate the cake with cream cheese. The question is that the figurine that should stand on the cake must be dry. The figurine stood for a day, but did not dry out much. Is it a matter of mastic, or has not enough time passed? I buy ready-made mastic.

Lesya, we have a detailed article on how to dry mastic figures https://retseptytortov.ru/ukrashenie-tortov/kak-pravilno-sushit-izdeliya-iz-mastiki-sovety/ Usually the figures dry simply in the air for about a day, but it may take more time. It depends on how you dried them. Don’t worry, such decorations can be made even a few weeks before using them)

Hello, I am making a cupcake with cream on top, I need to put a circle of mastic on the cream, will the mastic melt on the cream? Chantipak cream. Thank you.

Lena, the products must be covered with a cream that will not cause the mastic to run. Under no circumstances should mastic be placed on yoghurt cream, whipped cream, sour cream, etc. You can use any cream with added oil under the mastic (for example, butter + condensed milk, Charlotte cream, custard, ganache, etc.)

Lena, in principle they shouldn’t have leaked in such a time, maybe you didn’t wait until they were completely dry? But, if you are worried, then as an option: store the cupcakes in the refrigerator, transport them separately from the decorations, and decorate your desserts with them on the spot, placing them on the cream.

How to apply bitumen mastic?

There are a lot of options for applying bitumen mastic. It all depends on its consistency, concentration and conditions of use. It is clear that it will usually be very difficult to apply cold mastic with a painting brush. Due to the fact that the composition is cold, the brush will get stuck, hairs will stick and be torn out. As a result, the tool may completely freeze in a jar of mastic.

Also, the surface on which the composition is applied plays an important role. If you are fundamentally unfamiliar with the technology of installing membrane roofing, then we do not recommend working with it without preparation. You risk damaging the tool, the solution itself, and most importantly, damaging yourself. Especially if it gets very hot.

Let's return to surfaces. Firstly, based on its area, the type of work is determined. If the area is small, it is possible to apply mastic to the required places with human effort. If this is a full-fledged roof of a house or a facade, then it is better to use a mechanized method.

For the manual method, a short-haired roller or a fluted brush is suitable. It differs from a regular brush in that it is more resistant to the viscosity of bitumen. Thus, it better distributes the product over the surface without allowing streaks and unevenness. If mastic is applied mechanically, this is done with a special mechanical sprayer. Under its pressure, the product is distributed evenly and symmetrically.

Application of bitumen mastics and rules for working with them

Bitumen mastic is a homogeneous plastic substance made on the basis of bitumen and various additives that improve its properties. It has excellent physical and chemical properties, which make it an ideal waterproofing and adhesive material. After application to the surface, the mastic quickly hardens.

Bituminous mastics are used in any field of construction, covering most surfaces with them, including their use:

For the roof

Using bitumen mastic for roofing, you can quickly and efficiently seal the surface, without the use of equipment. The mastic can be applied to any cleaned and smooth roof surface.

Brief instructions and reminder:

• Bitumen mastic is applied with a hard brush or brush in a thin layer. It is better to apply to a small damaged surface with a spatula.
• When repairing a soft roof, the swelling area is cut crosswise, the interior is cleaned and dried, and then thoroughly treated with mastic.
• Mastic “patches” are sprinkled with sand to protect them from overheating.
• After cleaning, a cracked roofing felt roof is covered with hot mastic, when working with which you must be as careful as possible. Coating waterproofing is the simplest, most reliable and economical type of repair work.

Roofing work using bitumen mastic:

Roofs treated with mastic have a long service life. If it does need repairs, repairing the roof will be very simple.

To repair the roof with bitumen mastic, the following work is carried out:

• Eliminate coating defects.
• Cut the bubbles on the coating by making cross-shaped cuts and dry them.
• The surfaces inside the cut are coated with mastic.
• The edges of the incision are connected, aligned and fixed.
• A layer of mastic is applied to the cuts, fiberglass is laid in the form of a strip 10 cm wide and the mastic is reapplied.
• Large cracks and breaks are treated in the same way.

For roofing felt

Mastic for roofing felt is one of the most reliable methods of fastening it. Mastic helps to securely fasten roofing felt to the roof and remove air pockets. The roof surface is smooth and can withstand loads well. Hot and cold mastic are suitable.

For waterproofing

To protect structures located in the ground from moisture, waterproofing mastic is used. It waterproofs bathrooms, pipelines, and creates seamless waterproofing coatings in basements, wells and swimming pools.

Buildings treated with bitumen mastic for waterproofing also gain protection from fire.

For the foundation

For all types of waterproofing, one cannot do without mastic made from petroleum bitumen, to which organic and mineral solvents and fillers are added.

This mastic is the best waterproofing material due to the following properties:

1. elasticity;
2. frost resistance;
3. good adhesion;
4. resistance to ultraviolet radiation;
5. ease of application.

The foundation is treated in several layers of bitumen mastic on all sides, making it completely hydrolyzed. The cheapest coating is with hot bitumen, but it is more difficult to work with. To avoid difficulties, it is better to choose cold bitumen mastic with organic solvents (polymer). To work with it, you only need brushes and a spatula.

To treat the inside of the foundation, use water-based mastic. It has a neutral odor and dries quickly. In industrial construction, bitumen-latex emulsions are applied mechanically.

Waterproofing the foundation with mastic is carried out using brushes, rollers, and any tools that can be used to apply the composition to the surface. The mastic is applied in two layers, maintaining a technological pause between them. Its value depends on the characteristics of the composition.

The video shows how to properly waterproof a foundation with bitumen mastic:

Modern bitumen mastic is often used for floor protection. It is non-toxic and dries quickly. Bituminous floor mastic does not emit unpleasant odors. Most often it is used for waterproofing a bathroom.

For parquet

To attach parquet floors to concrete or cement-sand screeds, cold mastics are used:

1. bitumen-kukersol;
2. bitumen,
3. rubber-bitumen;
4. coumarone-cukersol.

The use of cold mastics is due to the fact that they set slowly, which allows you to accurately connect the planks into a tongue and groove. Parquet with an oblique edge can be laid on bitumen mastic.

For wood

For wood processing, MBU bitumen mastic is used. The treatment of wooden surfaces that are buried in the ground is especially important. If the mastic has become very thick, it is heated with the lid open and then mixed thoroughly.

For linoleum

Each type of linoleum is placed on “its own” mastic:

• Bituminous for fabric base.
• Dispersive – for a heat-insulating base.
• Mastics with the addition of synthetic resins and rubbers are suitable for baseless linoleum.
• Before laying linoleum on mastic, the floor is pre-primed. The mastic is applied to the floor with a notched trowel.

Gluing linoleum to mastic

For laminate

When laying laminate on bitumen mastic, the floor becomes warm, sound and moisture insulated. It is arranged in the same way as when laying parquet.

For metal

For metal and cars, bitumen-polymer and rubber-bitumen mastics are most suitable. It perfectly protects the car, but before processing the metal must be cleaned of dirt and rust, washed and dried.

For concrete

Although concrete is a monolithic product with increased strength, it always has microcracks and small pores through which water easily seeps. Because of this, the reinforcement may rust over time, and the foundation block may burst and sink into the ground. Therefore, concrete structures are treated with bitumen mastic, which reliably protects all cracks, pores and interpanel seams.

To do this, use various mastics made from:

1. solid bitumen;
2. liquefied;
3. waterproofing bitumen-rubber.

For expansion joints

To seal joints in concrete pavements, you can use hot bitumen or cold mastics produced by industry. They can withstand more than 200 thawing and freezing cycles.

Bitumen mastic for bridge expansion joints:

For asphalt

Special mastics are used to repair asphalt and seal the road surface. They withstand strong compression and stretching, have good adhesion, and can be used at low temperatures. Within an hour after the work, the road surface can be used.

For furnaces

To perform work on lining fireplaces and stoves, heat-resistant bitumen-polymer mastic is used. It can withstand temperatures up to +1200 °C and above. It dries quickly, does not emit odor, and prevents the development of fungi and mold. This is a heat-resistant, reliable, durable, bactericidal adhesive material.

For the pool

To seal the pool, thiokols and rubber-bitumen mastics are most often used. The mastics harden right in the seam and over time turn into an elastic black sealant. To fill the seams, use a pneumatic syringe with replaceable cartridges.

Applying special mastic to the bottom and walls of the pool

For expanded polystyrene

Recently, bitumen mastic has been used to reliably attach polystyrene sheets to metal, concrete, expanded clay, brick and wood. During work, vertical sheets of expanded polystyrene are fixed with temporary supports for reliable connection, and a load is placed on the horizontal sheets.

How to work with mastic

To create an effective waterproof layer, bitumen mastic is vigorously mixed using a drill or mixer.

For ease of application and increased plasticity, you can warm it up. Since the layer is elastic, it is better not to apply hot mastic to surfaces that are often subject to strong mechanical stress. A hot solution penetrates better into the pores, as it has increased fluidity and therefore adheres more firmly to the material being processed.

The preparation of hot mastic must be carried out observing safety precautions. Hot mastic is more profitable for large-scale work. Cold mastic is sold ready for use; it is safe to use and more convenient. But it costs more than hot.

They work with bitumen mastic at air temperatures from -10° to +50°C. The mastic itself should be heated in a water bath to +15 degrees and above.

When working with mastic, you need to be aware of its fire hazard and toxicity. It is forbidden to heat it over an open fire, or store it near a fire source. If work is carried out indoors, it is necessary to create ventilation.

Preparation of hot bitumen mastic:

Consumption and consumption rate

Consumption of bitumen mastic per 1m? depends on its type. The consumption indicator depends on the type of material. Hot bitumen mastics do not decrease in thickness after hardening, therefore they are considered non-shrinkable. To apply bitumen mastic in one layer 0.2 cm thick, it requires from 2.0 to 2.4 kg/m2.

An important characteristic of mastic consumption is the dry residue content. This is the amount that remains on the treated surface after it has dried and hardened. With a small dry residue, the consumption of the original mastic is increased to form a film of a given thickness.

In dry matter, to create a layer 2 mm thick will you need 3.4-3.8 kg/m? bitumen mastic. Most ready-to-use mastics have a solids content of 20 to 70 percent.

Applying mastic

In order for the mastic to adhere well to the treated surface, it is necessary to thoroughly clean the treated area from all types of contaminants. After this, the finished surface is thoroughly dried and heated. Thanks to this approach, the mastic will be applied evenly and you can save on its consumption.

The most popular tool for applying it is a brush or roller. They apply mastic and apply it like regular paint, without rubbing it too hard into the surface. After drying, re-processing is done.

Bitumen-latex compounds can be applied using machine airless spraying. This method produces a uniform layer and low material consumption

You can also apply mastic using a pour-on application by pouring it onto the surface and leveling it with scrapers, mops or long-handled rollers. Although this method has higher productivity, more material is consumed.

How can you dilute the mastic?

Bitumen mastic is diluted with white spirit, solvent, toluene or kerosene until the required consistency is formed. After this, it is thoroughly stirred.

What is the difference between primer and bitumen mastic?

To understand the difference between primer and mastic, it is enough to know the definitions of both terms. By the way, this will help you reduce the cost of installing a PVC membrane on the roof, since you will know the basic qualities of the material. So, we have already figured out what bitumen mastic means.

In turn, bitumen primer is, in principle, a product similar in composition. Only it is produced on the basis of bitumen, and contains various solvents of organic origin. Also, the components of the bitumen primer are minerals and polyminerals.

The primer should only be applied to a previously cleaned and degreased surface. Due to its more liquid and watery structure, the primer is able to penetrate deeper, thereby filling all voids and internal cracks/chips. This is very important when treating membrane soft roofing with similar materials.

Advantages and disadvantages

Due to the use of simplified technologies in the production of this type of mastic, it is becoming increasingly popular among consumers. Taking this into account, cold-applied mastics based on bitumen are becoming a common material for waterproofing.

Bitumen mastic has a number of positive qualities:

• dries instantly;
• can be used for spot repairs;
• easy to use, even a non-professional can handle it;
• there is no need to use special equipment for heating, unlike the hot type, which greatly simplifies the process;
• it can work on wood, metal, concrete or plastic surfaces;
• has elasticity;
• upon application, penetrates into the coating structure;
• due to their unique composition they are resistant to atmospheric conditions, temperature fluctuations, and ultraviolet radiation;
• a wide range of colors of mastics is achieved by adding coloring pigments;
• water-based mastics are used for internal insulation of premises.

In addition to the advantages, there are also some negative points:

• the material is flammable;
• High-end cold mastic may cost more than hot mastic.

How to wash bitumen mastic?

If you are faced with a situation where you need to wash bitumen mastic, the first thing it could be is a solvent. But let us immediately note that this works if the composition is still hot or warm. When the mastic has already hardened, especially concentrated, and some time has passed, then simply erasing it chemically will be very difficult and energy-consuming.

You need to understand that the mastic contains petroleum products. This gives it additional resistance to laundering. Therefore, when choosing a product, it is necessary to consider what type of surface it will need to be cleaned from. In addition, the volume of excess plays a big role in the choice of cleaning method and product.

As we have already said, bitumen contains an impressive percentage of petroleum products. This allows the mastic to be used in almost all types of construction work, including when laying and installing PVC roofing on the roof.

Mastic is, to put it mildly, a sticky material. Once cooled, it literally solders to the surface. Therefore, if even a small amount of bitumen gets on clothes or other things, you can’t just wipe it off. Mastic can only be removed by heating it to at least 50 degrees.

The biggest mistake most people make is to immediately aggressively tear off the mastic and try to scrape it off. This will completely damage the material to the point that it cannot be restored. If the bitumen layer is too thick, then it makes sense to heat it and cut off a little thickness. But this is the maximum that will have to be done.

How to prepare the right solution

An important point in the process of preparing mastic is the method of applying it to the surface to be treated. The protective solution can be applied either manually or using special equipment. The manual application method is relevant when the amount of work is small. If it is necessary to apply the composition over a large area, then mechanized application methods are used. The method of mixing depends on how the mastic will be applied. How to dilute rubber-bitumen mastic? Before you start preparing the mixture, you need to prepare the surface on which the composition will be applied.

What is bitumen mastic used for?

It makes no sense to talk a lot about what bitumen mastic is needed for. Indeed, due to its properties, which are tightness and at the same time elasticity, the composition is actively used in construction for most repair work. Mastic has no less significant use in laying roofing materials.

And, of course, bitumen, as the primary material, is used in laying asphalt. Thus, hot asphalt chips are hermetically fixed to the road surface, supporting the weight of even particularly heavy cars and heavy trucks. Yes, the composition of road bitumen differs from the mastic used for waterproofing roofs, foundations, swimming pools or ponds. But the basis of the composition and its technical characteristics are similar.

Bitumen mastic or primer: which is better?

If you are choosing between bitumen mastic and primer and don’t know which is better, be sure to read this part of the article. By the way, if you decide to install a soft roof with your own hands according to the instructions, this issue will definitely be on the agenda. It would seem that they are two similar products, but which is better?

Let us say right away that for each case a different composition is selected. It all depends, as a rule, on the surface on which the primer or mastic will be applied, the conditions of application and the type of work. In general, the most important difference between one product and another lies in the scope of their application.

Bitumen mastic is used for waterproofing work on roofs, facades, foundations or water tanks, etc. The primer, in turn, is used for road work, including when laying crushed stone and asphalt chips, and carrying out communications, namely gas or water.

Of course, when eliminating corrosion and other mechanical damage to the pipeline, the primer has no place. If the list of repair work includes priming the surface, the primer will become an indispensable component for this activity. Having found out what dismantling of structures is, you will learn what role both mastic and primer play in this work. And also whether they are needed there in principle or not.

Consumption

Material consumption depends on the area being treated and the number of layers. It is influenced by the material from which the base is made and its density. Consumption is affected by the composition and quality of the product.

Typically the consumption ranges from 300 to 900 grams per square meter.

Bituminous mastic in packaging

The consumption also depends on the method of waterproofing. When coating, more will be required, since more layers of greater thickness are needed.

Approximate consumption can be found from the manufacturer's information on the packaging. Average data is indicated there, but they are used as a guide. The consumption is affected by whether a primer was used or not.

In the video you can see the process of preparing primer and mastic:

Bitumen mastic does not dry: what to do?

If bitumen mastic does not dry, this can become a serious obstacle to work. So what to do and how to deal with it, so to speak. When an estimate is drawn up for repairing the soft roof of an apartment building, this point is not taken into account by contractors. However, even an experienced worker can face this difficulty.

Such cases arise, as a rule, due to the lack of time available for the bitumen to dry. Many workers, due to inexperience or other reasons, assume that the drying process itself does not take much time. But, fortunately, there are quite simple, but at the same time, productive methods to speed up the drying process of the composition.

The most common method is used at the stage of applying mastic to the surface. Instead of rollers/brushes and other means, it is better to apply the mastic with a spatula. Due to the formation of so-called grooves, the solvent contained in the composition will evaporate faster, which means the bitumen itself will dry faster.

After applying mastic to a certain area, it is very important to ensure that it is isolated from direct moisture, even in small quantities. Also, it is better to provide constant air access to the treated area in order to create circulation. You should not cover the areas with polyethylene or stretch film, as such manipulations will block the access of air, which will negatively affect the drying of the composition.

If the work is carried out in an open space, it would not be a bad idea to install devices for artificial drying, for example, heaters, heat guns, fans. As for the drying speed of mastic on roofs, it all depends on the type of soft roof for the garage and its area.

How to dry mastic: useful advice

• Dry room at room temperature
• Starch or powdered sugar
• Hairdryer with cold air mode

To decorate a homemade cake, imagination and artistic taste are not enough. We need knowledge that will help preserve its beauty and avoid unpleasant surprises when, before serving the delicacy, it turns out that the decor has lost its shape. One of the most popular ways to decorate cakes is to decorate them with mastic figures. The features of this material allow you not to limit yourself in the choice of colors, and its plasticity makes it possible to mold almost any figure. You just need to know how to dry the mastic so that the figures do not “float”, retain their shape, and also do not become covered with cracks. It is best to dry decorative elements in a ventilated, dry room at room temperature. To prevent dust from entering, the figures can be covered with a dry paper or cloth napkin. When drying large mastic figures, cracks may form. This occurs due to the fact that a large mass of material cannot be dried evenly. You should think about how to make a baby out of mastic in advance, because complete drying will take about a day. To avoid cracks, large figures can be made from smaller fragments and then glued together, or you can use filler and wrap it in mastic.

It happens that you need to dry your jewelry faster. Friends or relatives called and asked for help in organizing a home celebration, and now you need to think about how to make swans from mastic, and most importantly, how to dry the resulting figures quickly. Rolling out the material on a board generously sprinkled with starch can help solve this problem. The resulting figures dry noticeably faster. Powdered sugar, used in the same way, works a little worse, but it also speeds up the drying process. When creating multi-colored figures, you can make them from ordinary white mass and then paint them, however, in most cases, housewives want to learn how to make colored mastic and sculpt them from already painted material.

Polymer-bitumen mastic: what is it used for?

And the last thing we have to deal with in this article is why and where polymer-bitumen mastic is used. In general, this material is primarily used for waterproofing and vapor barrier of facades and roofs. And also, the interfloor ceiling is treated to protect it from mechanical damage and the effects of climatic conditions.

Within our country this is most important. Since in some cities high humidity prevails in symbiosis with hot weather. While in more northern latitudes there are stable frosts and cold precipitation most of the year.

Thus, bitumen mastic is a high-quality and widely used material. Despite its relatively recent introduction to the Russian market, the composition of waterproofing bitumen has rapidly gained popularity and deservedly positive reviews from users.
