HYDROLAST-PU/W | Water-thinnable waterproofing mastic based on polyurethane resins.
-
After applying to the surface, it polymerizes, creating an elastic membrane that is resistant to excessive ultraviolet radiation and high mechanical stress;
-
It has excellent adhesion to all types of building materials;
-
The material is applicable for waterproofing external surfaces, vertical and horizontal structures, as well as for waterproofing tanks, florists and wet rooms.
-
Consumption: 1.0-1.2 kg/m2 for two layers;
-
White color;
-
On request: gray and tiled;
- It has high mechanical strength;
-
Terraces covered with this material are suitable for intensive walking ;
-
Highly resistant to standing water;
-
It has excellent adhesion to any kind of building material : concrete, cement-lime plaster, drywall, brick and wood;
-
It has exceptional elasticity, effectively covering surface cracks with a width of 1.0 mm to 1.5 mm without the use of reinforcing material;
-
Due to its white color and physical and chemical properties, the material perfectly protects the surface of structures from ultraviolet radiation;
-
The smoothness of the surface to be coated is not required;
-
Resistant and hardy to alkaline-acid influences, as well as to atmospheric precipitation;
-
Waterproofing terraces, balconies, walls, as well as the surfaces of wet rooms, even with slight slopes;
- It is used as a waterproofing coating on almost any surface , including fresh and old coatings, both acrylic and polyurethane.

Base
-
The base must be solid, free from dust, loose fragments, traces of dirt, paints, oil stains, etc.;
-
The humidity of the base must not exceed 4%, the relative humidity of the environment must be less than 80%, and the temperature within the range from + 10 °С to + 40 °С;
-
The surface is pre-primed with PRIMER or VIM-PRIMER-S, especially if it is porous;
-
The material is applied with a brush or roller, in two layers, in the same direction or crosswise;
-
For the first layer, the material is diluted with 5% water composition;
-
The second layer is applied after the first one has dried, after 24 hours, at an ambient temperature of +25 °C and without diluting the material with water;
-
In case of cracks larger than 1.5mm, surface cracks are covered with a special polypropylene (PP) tape or glass fiber;
-
This reinforcement is fastened with fresh HYDROLAST-PU / W and then two subsequent layers of coating are already applied;
-
Reinforce should be carefully and carefully to avoid the formation of voids in these places;
-
Of course, when performing such work, material consumption may increase by an additional 0.5 kg / m2
-
Full and intensive walking on the terrace is permissible after 7 days from the date of completion of the work, after applying the material;
-
Stably retains its properties in the temperature range from -15 ° C to + 80 ° C;
-
It is resistant to ultraviolet radiation, therefore it has increased durability;
-
The material provides a high degree of water resistance of the entire surface, since it does not create seams and joints that are inevitable in other types of waterproofing work;
-
Economical due to easy application and low consumption;
- The material has a long life span, as well as a long shelf life, in comparison with the classic types of sealing coatings.
