DIY liquid rubber for waterproofing

Any building needs to be waterproofed, and liquid rubber is one of the best materials on the market right now. This adaptable substance offers a smooth, flexible barrier that can stave off water damage to your roof. Additionally, you can complete the project on your own and avoid paying for professional assistance.

Not only is DIY liquid rubber application reasonably priced, but it’s also quite simple to execute. Your roof will remain safe and dry if you apply a long-lasting waterproof layer with the correct equipment and some forethought. In places where traditional materials might not be sufficient, such as flat roofs or areas where water tends to pool, this method is particularly helpful.

We’ll walk you through the application of liquid rubber to waterproof your roof in this article. Everything will be covered, including product selection, coating application, and roof surface preparation. By the end, you’ll be equipped with the information and self-assurance needed to properly and efficiently protect your roof.

Waterproofing of the foundation with liquid rubber

A relatively new technique for shielding underground building structures from water contact is waterproofing the foundation with liquid rubber. It enables you to consistently isolate inaccessible and solid portions of the base where roller materials are useless. We’ll explain how to do this kind of waterproofing in this article.

Features of waterproofing with liquid rubber

Though this material is actually an isolation of bitumen and polymer, it gets its name from its outward resemblance to conventional rubber in a hardened state. Liquid rubber is a system made up of one or two parts in its initial state. The bitumen emulsion is the primary component, with additional polymers and stabilizers adding unique qualities to the final protective layer.

Pros and cons of the foundation insulation with liquid rubber

Considering that the ideal coating thickness based on liquid rubber is limited to two to three millimeters, its operating parameters are comparable to those of comparable indicators of roofing material that is adhered to the foundation in multiple layers. As the rubber coating is entirely monolithic in this instance, there is no need to seal the seams between the roll material’s canvases.

  • It can be used in the temperature range from -50 to +98 degrees, with severe heating, bitumen -polymer isolation melts, but does not burn.

The high cost of the material in comparison to roofing material and the requirement for the contractor’s qualification when working with the installation for spraying the emulsion are the drawbacks of using liquid rubber as a waterproofing for the foundation. In spite of these drawbacks, it is evident that the more sophisticated technique of applying liquid rubber to waterproof a foundation is clearly superior to the more traditional methods when it comes to the majority of fundamental indicators, such as the coating’s elasticity, dependability, tightness, and monolithicity.

Preparation for the insulation of the foundation with liquid rubber

One essential step in waterproofing the foundation is preparation work. If the building is already occupied, the portion that is underground must be removed from the ground before being thoroughly inspected.

Technology for applying liquid rubber to the foundation

It is highly discouraged to work on liquid waterproofing in the rain or snow, regardless of the technique used on the foundation.

  1. With manual application, it is 1.1;

The foundation must be manually processed with an emulsion in multiple layers in order to achieve the required waterproofing coating thickness. The material is applied in a single layer using the automated method. In any event, the protective coating’s thickness shouldn’t be any less than 2 mm. The waterproofing layer of the foundation should be 2-4 mm thick, or more than 10 m, 4-6 mm, when it is laid to a depth of 10 m. An average of 3 kg/m 2 of liquid rubber is needed to cover an area that is 2 mm thick.

Lastly, I would like to express the following. Liquid rubber offers far more benefits than drawbacks, in any case. Coatings made of two-component liquid rubber mixtures for the foundation have a longer service life and more dependable moisture protection. Although one-component compositions are far less expensive, it is preferable to select the first waterproofing option if your budget will allow it.

The application of liquid rubber, its characteristics, benefits, and drawbacks, the stage of preparation for the job, and the technology involved in its use to waterproof the foundation.

  6. Thanks to its aggregate state, it allows you to create a sealed continuous carpet coating without the formation of seams, overflow.
  7. Static strength is 0.4-0.5 MPa.
  8. Is a protective tool – protects processed materials from corrosion.

Due to its numerous technical and financial benefits, insulating material’s qualities have been adopted by numerous industries.

  • belongs to the group of explosive and fireproof materials;
  • Liquid rubber is not toxic, without a pungent odor, has environmental purity, which allowed it to be used in production facilities associated with the food industry;
  • It is applied to all types of surfaces, including with a complex relief, inclined at a negative angle to the vertical or horizontal, as well as inaccessible for ordinary types of processing;
  • The sealed base does not require special surface preparation;
  • One team of three workers can cover an area of ​​up to 1400-1600 m² per shift;
  • Due to the small mass, the coating does not require additional reinforcement and hardening of the surface on which it is applied;
  • inertia in relation to bacteriological damage to the fungus, mold;
  • economically in use – a 2 mm thick coating can replace a flooring consisting of a four -layer rolled insulating material;
  • It has soundproofing properties – the applied liquid rubber 1 mm thick is equivalent to a one -time layer of brick brick masonry.

The use of insulating material

Owing to its numerous applications and advantageous qualities, this substance is utilized in numerous industries.

In both the public and private sectors of housing construction, liquid tires are utilized:

  • waterproofing of the roof of household and industrial buildings;
  • coating with a protective composition of foundations, underground structures – bomb shelters, tunnels, underground crossings, basements of houses and garages;
  • insulation of hydraulic structures – gradins, pools, wells, fire reservoirs, emergency containers with technical or drinking water;
  • used as vapor barrier, as well as anti -corrosion coating.

The method is liquid waterproofing:

  • to cover the bottom, parts of the car body;
  • for anti -corrosion protection of metal structural elements.

Mastic is used in the manufacturing of food, chemicals, and metals as:

  • protection of water tanks;
  • anti -corrosion coating with chemical reagents;
  • processing of industrial areas that carry out cleaning and detergents;
  • Sound insulator of metal vibrating structures.

The purpose of the waterproofing is:

  • processing of silage pits;
  • protection of tanks with water and liquid fertilizers;
  • anti -corrosion treatment of irrigation systems.

Liquid rubber was also used in this situation:

  • coating of pools and tanks used to store acidic or alkaline liquids;
  • impregnation of various surfaces to protect against leaks of aggressive liquids, production waste.

Surface preparation

The following preparatory steps must be taken to prepare the surface before applying liquid rubber:

  • carry out work related to the alignment of the surface – with technological requirements or further application of decorative coating;
  • Remove garbage, mud deposits, dilute and degrease the surface;
  • apply a primer – is used in the case of use of decorative rubber instead of the paintwork.

Application of liquid rubber

There are several methods employed:

  1. Bulk – mastic is prepared directly at the place of use with further spill and leveling the level. The method is applicable for horizontal surfaces.
  2. Coloring – liquid rubber is applied by painting tools (brushes, rollers, spatulas). Manual labor is used. Carried out on small surfaces in area.
  3. Sprayed – the most progressive method. The method of cold spraying is used, which allows you to repeatedly increase labor productivity. It is used to cover large surfaces, inaccessible places, complex relief structures.

When using the sprayed application method, specialized equipment from the RX, UZHK-2C, and other comparable series is utilized. This equipment includes:

  • electric or gasoline engine;
  • air compressor;
  • containers with liquid rubber built into a single structure, or a separate tank;
  • valve systems, adapters;
  • strong hoses;
  • sprayer (spray gun) with a bar extension cord (if necessary).

Protip: make quicker product purchases

Local producers or nearby nations, as the cost of imported European or American machinery and liquid rubber is significantly higher.

Individual protective equipment is required when producing paintwork with a liquid waterproofer:

  • protective suit (overalls);
  • glasses or a transparent protective shield;
  • respirator protecting the respiratory tract;
  • a headdress that completely closes the upper part of the head;
  • gloves;
  • Shoes (rubber boots).

The industry that uses the sprayed application method packs liquid rubber into 200-liter barrels. A two-component emulsion is created when a polymer bitumen reagent is combined with a CACL solution in water. This emulsion is then polymerized quickly, resulting in the formation of a homogenous elastic mass.

A bitumen-based, one-component mastic that comes in containers weighing between two and twenty-five kilograms is used for painting. It is utilized for small items in the scope of the project, such as waterproofing cellars, foundations, viewing pits in the garage, and small private pools.

Application for personal use has the advantage of not requiring you to deal with the hazardous and difficult tasks of heating up hard bitumen. Furthermore, considering the financial side of things, waterproofing can be applied much more quickly, saving a great deal of time and labor while also greatly enhancing ongoing work safety.
