When waterproofing a material with two components, this mastic needs to be pre-mixed with its individual constituents. Cold mastic is used without preheating. Despite this, hot compositions are only used with preheating, and the heating temperature should be at least 180 degrees. Compositions that are applied heated, are able to penetrate much deeper while filling some cracks and other damaged places. To improve adhesion to the wall surface, use primers that serve as a primer.

  • mastic Tekhnonikol No. 33. The composition is made on bitumen water-emulsion base and other components without organic solvents. Can be applied by roller, brush or spray method;
  • mastic "Technonikol" hot application №41 or №45 (Eureka). First of all, this material is intended for sealing of small cracks and other damages in walls of concrete, blocks and reinforced concrete structures;
  • bitumen waterproofing AguaMast. This composition is applied exclusively to foundations and basements with high humidity;
  • primer «Technonikol» №04. This substance is used for indoor use before applying mastic. Used to improve adhesion.

The compositions presented above have a lot of advantages, such as ease of application, durability of materials, frost resistance, good adhesion to the wall surface, versatility of the substance, you can apply it not only for the surface of the basement, but also for the internal basement rooms and even waterproofing roofing. All other features of each of the materials you need to familiarize with when buying a construction shop.
