At present, the world produces more than three thousand types of paints and varnishes for various purposes. In this article, we will consider all the characteristics and features of the application of the recently appeared and already won the trust of both professional builders and ordinary people, rubber paint.
This product is an acrylic emulsion , created on a water-dispersion basis using synthetic acrylate latex - a material with increased elasticity, resistance to aggressive temperature conditions and extremely low hygroscopicity.
In addition to water, the chemical composition of the paint also includes the following elements:
Properties of rubber paint
After complete drying, it is warm to the touch, the structure resembles rubber or soft rubber, elasticity is not less than 350%.
Advantages of rubber paint
Ratio of volume to weight: in one liter 1.1 kg of paint.
One layer of 50 microns (average thickness of the primary coating applied with a brush) completely cures in 12 hours, stops sticking - after 2-3 hours at a temperature of 25 ° C.
Dry residue - up to 50%.
Features of rubber paints
The warranty period of the coating is 10 years (especially wear-resistant up to 20).
The shelf life of a closed container is up to 3 years, after opening the container - up to 6 months.
Storage conditions: in a closed or (after opening) hermetically sealed container at temperatures from -5 ° to 25 ° C. When cooled and frozen (5 cycles, but not more than 30 days to -20 ° C), the paint can be thawed, leaving it at room temperature for a day.
Before use, be sure to stir until the bottom sediment disappears.
Be sure to stir the paint
Despite the different purpose indicated on the container: "For the roof", "For concrete", "For metal", all rubber paint has almost identical properties, with the only difference that a more active pigment is added to the "For the roof" composition, "For concrete" contains more acrylatex and antifreeze, and "For metal" differs in the amount of coalescent.
General recommendations for working with rubber paint
The exception is very expensive paint production, the warranty period of which is 25-30 years - it is considered to be really particularly wear-resistant.
The definition "for outdoor use" is also an incomplete and insufficient characteristic of the intended purpose of rubber paint, since its practical application is much wider.
Thus, any rubber paint with a warranty period of up to 10 years is designed to perform a whole range of works, including:
Rubber paint for slate
The use of rubber paint for painting a children's play complex
The waterproofness of rubber paints has made them almost indispensable for the arrangement of home swimming pools
Our advice: prohibition of use emulsions for painting floors and furniture are the manufacturer's recommendation, but experience shows that after a certain preparation, the coating withstands well, for example, application to the floorboards of an outdoor gazebo. Based on this, the use of non-toxic and environmentally friendly paint for the purposes described above is a personal matter for the owner.

Features of using rubber paint
This step is very important if you really want to test the full margin of safety of rubber paint.
You cannot ignore it.
Goal: to achieve the most even, non-porous clean surface.
1. Use a metal brush, putty knife, trowel net or sandpaper to very thoroughly clean the surface of dirt, dust, mold, moss and traces of previous processing.
Particular attention should be paid to traces of whitewashing with hydrated lime and residues of oil or alkyd paint - they must be cleaned off before plaster or putty.

2. Rub oil and grease stains until they disappear completely. If the fat is too deep, soak it with dishwashing liquid for 2-3 hours, occasionally moistening it additionally - the stain should be washed off.
3. Glossy parts of wooden structures, MDF, fiberboard must be sanded to dullness.

4. If cracks are present, they must be putty and, after drying, sanded.

5. All metal surfaces are cleaned of dirt, dust and traces of previous staining with a metal brush, polished and degreased with a solvent such as white spirit. In the presence of gloss, it is advisable to sand to a matt finish to improve adhesion to paint.

6.After the completion of all work on cleaning, filling, sanding and grinding, the surface is freed from the remnants of construction dust, and then washed out with an alkaline solution (optimally: dilute sodium phosphate with water 1: 200). After 20-30 minutes, it is washed again with clean water and kept until completely dry.
1. Metal elements are coated with an anti-corrosion compound before priming, and then with an insulating or inhibiting primer.
It is possible to use a special primer with anti-corrosion properties such as GF-021.
Important: if the surface after priming turns out to be glossy, then sand it a little to a matte shade ...
Concrete, cement, asbestos-cement and other porous surfaces are coated at least twice with a facade or antiseptic deep penetration primer.

3. The wooden parts are coated with a silicone-acrylic primer.

4. All other surfaces can be protected with a universal acrylic or latex primer.
5. If the surfaces to be prepared will be exposed to regular aggressive environmental influences (rain, snow, etc.), then additional coating with a hydrophobic primer such as Ceresit CT 19 is allowed.

Our advice: if you apply the primer in two or more coats, first let the first coat dry completely and then apply the next one.
The following tools are used for painting: paint brush, foam rubber or artificial polyamide fur rollers, spray gun.
| Type |
|Brush (in g)|| Roller |
| Spray gun |
( in gr)
|Drying time of one layer||Recommended number of layers|
|Concrete, cement, stone, clay, asbestos cement||170-200||150-170||130-150||12 |
|Metal||130-150||120-140||120- 130|| 12-14
|Wood||150-170||130-160||110-130|| 12 |
|Others||150-170||130-160||110-130|| 12 |
Optimum weather and temperature conditions for painting:
Important: paint dilution with water is allowed only when the first layer is applied and no more than 10% of the total volume.
Application of rubber paint with a spray gun
Features of coloring:
This is difficult to achieve with a roller, especially in corners and other hard-to-reach places, so be sure to paint over imperfections with a brush (each layer must completely cover the surface);
Very important! It is possible to wash and actively influence the painted surfaces no less than a week after the end of the painting - it is during this period that the emulsion completely hardens and acquires all wear-resistant qualities.

Approximate prices for one liter of rubber paint (in rubles):
SuperDecor rubber paint
Rezolux Universal.Rubber paint
Plasti Dip - rubber paint
The line of paints by the American manufacturer "PlastDip" contains glossy and even fluorescent colors ( both in cans and in aerosols).
We have provided a complete description of the characteristics, as well as step-by-step instructions for working with rubber paint, and we really hope that when planning a repair, our article will help you make the right choice.
