Concrete adhesive is a copolymer resin based on vinyl acetate resin that has high adhesion and its dried film is colorless, transparent and flexible.
Application of the product
The application of this adhesive in the construction industry is bridge construction, dam construction, etc. By adding this adhesive to cement and concrete production, waterproof concrete that is completely water resistant can be produced. ” This adhesive can also be used in the production of waterproof cement blocks.
How to use
Preparation of softening coating with the formula: (three-dimensional silica rock soil + one-measure cement) Instead of water from the solution (one measure of 12000 + SA one or two measures of water) add the required amount to prepare the softening mortar. The resulting mortar is applied to a maximum thickness of 3 mm on the primer surface after primer with a metal trowel and smoothed.
These mortars can be applied in two layers in 24 hours on weak points in water resources. In positions that require leveling the surface, immediately after application, acrylic mesh or mesh can be laid on the surface and trowel to remove the mortar from the mesh hole and a coating can be applied to the surface.
Lining mortar and top coat can be used alone for sealing. Acrylic mesh can be used topically or nationwide to increase reliability. To seal water and sewage resources without the use of acrylic mesh, the above primer, primer, primer and softening mortar are used, respectively. After applying the coating for up to 5 days, the surface is kept away from wet sunlight and after 10 days, the surface can be used for dewatering.
How to make a primer
Preparation of primer according to the formula: (one measure + SA12000 three measures of water)
The resulting solution is applied to the concrete surface with a brush before each application.
It is recommended to wear glasses, gloves and work clothes with concrete glue during execution.
In case of contact of concrete adhesive with the skin, it must be washed with water before drying.
In case of contact of concrete adhesive with the eyes or penetration into the mouth, immediately wash with plenty of water and see a doctor
Structural concrete adhesive should be stored at temperatures of +5 to +30 C. Concrete adhesive can be used up to 12 months after production date.
