Liquid rubber for waterproofing - application features: Overview + Video Liquid rubber for waterproofing - application features. Liquid rubber for waterproofing - this material includes versatility, as it is often used on large construction sites. It is used to protect the foundation and other structures from the negative effects of moisture.

Liquid rubber for waterproofing has a wide range of applications.

General information

Composition and features of the material

Liquid rubber for waterproofing - application features: Overview + Video This material contains a bitumen emulsion, as well as components of polymer properties, several groups of hardeners and stabilizers.

Although in many respects a finished product is a campaign for rubber, from which it got its name, but in composition it is a slightly different material.

Rapid hardening of the mass is carried out when the product is applied to the surface requiring processing in a cold and liquid form, and after the final appearance of the material it begins to give high results in terms of adhesion, that is, strong adhesion to all kinds of building surfaces. The composition itself is sold in the form of liquid products, in containers, the volume of which is 200 liters. These are usually large barrels.

In order to quickly achieve the required result in the form of a hardened material, the surface to be treated should be covered with a solution of calcium chloride, which will accelerate the hardening time of the mass.

Only then will the result be similar to a monolithic rubber coating that does not have seams.

Where is liquid rubber used?

Even after completely drying, liquid rubber for waterproofing (as confirmed by a lot of reviews) remains elastic. Where do you need to use such material in the first place? These are various joints, gaps, cracks, cracks. It also requires sealing rooms that have a high level of moisture, such as basements, swimming pools, garages and other outbuildings. It is also possible to waterproof the foundation with liquid rubber, the basement of any type of structure.

Everywhere we get an equally good, and most importantly, stable result.

Also, the material can be used inside the dwelling, especially when the building has gone with small cracks. In this case, the protective layer should be applied on both sides of the object - on the inside and outside.

Product advantages

This product is distinguished by the fact that it has a lot of undeniable advantages that make it possible to gain popularity among buyers. For this reason, waterproofing with liquid rubber has most often positive reviews.

So, the advantages are as follows:

  • Liquid rubber for waterproofing - application features: Overview + Video Waterproofing ability of the coating at a high level of quality.
  • It is possible to tightly fill porous formations.
  • Solid, adhesion to concrete structures, wood and surfaces made of metal.
  • The method is quite simple, the material hardens quickly under standard weather conditions.
  • Environmental friendliness, durability.

  • Safety, since the material will not harm a person, even with direct contact.
  • Resistant to fire.
  • Long operational life.
  • Elasticity.

In its features and characteristics of operation, especially as a waterproofing material, liquid rubber leaves similar materials far behind.

Its layer, the thickness of which will be equal to 0.2 cm, will give a similar effect as a coating with a thickness of 0.8 cm with rolled roofing felt, and 0.6 cm, if it is a fiberglass membrane. The elastic ability will be much better than other similar materials, the ability to operate at temperature conditions is a big difference - from -45 to +96 degrees.

From this it is worth concluding that the material can be used in almost any climate.

Technical tests of liquid rubber for waterproofing on complete hardening of the composition give the following results - at a temperature of + 18 + 20 degrees, the time for obtaining all the standard properties of the products, as well as obtaining full elasticity, will be only 3.5 hours. At a slightly lower temperature, from +8 to +12 degrees, the time increases, but not much. When replacing material, it should not be removed, just apply a new compound over the old one.

Thus, the speed of work and drying should be attributed to the obvious advantages. It will be possible to move freely on the surface in just half an hour. Also, the service life of the finished coating is impressive - up to 25 years.

In addition, it should be noted the contact ability to wood, concrete and metal surfaces, as well as to stone and almost all other similar objects. High stickiness and viscosity make it possible to create a monolithic connection.

High resistance to mechanical damage is ensured by the viscosity of the product. And if, nevertheless, there are problems during operation, then it will not be difficult to complete the repair work and will not take much time. Applying a new layer with a thickness of 0.2 cm will help get rid of all the hassle for a long time. In addition, it should be noted that with such qualities, material consumption is minimal.


But the disadvantage of liquid rubber is that it has high resistance to intense and direct solar radiation. We also recommend that you carry out additional treatment with a water-based paintwork to increase resistance to UV radiation. Also, among the shortcomings, we note that the cost of the composition is quite high.

Therefore, in order to obtain quality coverage, it is very important to rely on the weather conditions. Do-it-yourself waterproofing with liquid rubber (according to reviews) cannot be performed if it is raining.

It is also not recommended to apply the composition if the processing surface is wet.The inability to use products at temperatures below +5 degrees makes it difficult to use the composition at low temperatures and its use in certain regions.

Moreover, sometimes it may be necessary to purchase special additional equipment in order to apply liquid rubber to the surface, and this will result in you a lump sum. The cost of the tools will be from 100,000 rubles, and it also requires personnel, craftsmen who know how to handle units. In addition, additional work is required to prepare the surface.

To do this, it will need to be cleaned, examined, washed with detergents. Next, it remains to completely dry everything.


Application of a layer of waterproofing is carried out in two ways - manually or by spraying with special equipment. You should also arm yourself with a device for mixing the composition in a special container. Spray application of the material is carried out under the influence of high pressure, and this will also require a certain skill of the master and technical conditions.

The installation drive can be gasoline or electric. In addition, you will be required to periodically mix the finished mixture. The processing process itself is the application of a wide strip with further preliminary drying. This way the layer can be brought to the required processing thickness.


The most commonly used devices are named RХ-27 and RХ-28.

They are electrical installations. There is an option with the equipment of engines that run on gasoline, but they are produced under the commodity code RX-33. The brands of liquid rubber for spraying are called Slavyanka, Daklar and others.

How to make waterproofing with your own hands

For economical and practical builders, it should be noted right away that liquid rubber for waterproofing makes it possible to reduce costs, albeit in a small amount. This is important for local, small surface repairs.

You will need:

  • A pair of medium jars of PVA glue.
  • Pack with drill.
  • Water (approximately 100-150 ml).

You can also add some kind of dye, but this is not necessary at all. Water should be mixed with borax, and glue with a coloring component, if you will be using it.

Next, mix everything thoroughly in different containers, then combine. If work requires a break, place the finished composition on a shelf in the refrigerator. As builders commented and responded, the composition is much more often used for industrial construction and much less often for private construction. This is due to the cost of the product, as well as the availability of equipment and well trained craftsmen. In general, this requires a lot of money.

Further, according to experts, the very type of coating at the end is not the most attractive. This feature applies to the outside, which is in full view of everyone.

The adhesion of the product is at a high level, but the builders keep repeating that work should only be carried out on a dry surface, and this is especially true for brickwork. The composition applied to a wet surface will not allow the steam to leave the treatment surface in the future, and this will threaten in winter with severe freezing of bricks, the appearance of condensation and destruction of the masonry as a whole.


Thus, for waterproofing, liquid rubber has many advantages, but still has some disadvantages.

According to the masters, the minuses are still much less than the pluses. Perhaps, for this reason, the material is very popular and widespread among professionals.
