Surface Preparations and Application:

Application surface, dust, loose parts, such as anti-stick material be free of oil is required. Successful application, the correct surface preparation and can be achieved by using the right materials. Application surface may be damp or wet ground. But should not puddles.

    • The surfaces of dust and waste with the help of an electric vacuum cleaner should be cleaned thoroughly. Wash the surface with clean water if necessary.

    • Applications will be cracks on the surface to be repaired with suitable materials.

    • The application will be covered with ceramic surface, which fully adheres to the surface of the ceramic material of the strength of the joints should be inspected and replaced if necessary or missing parts must be completed. 

    • Do not add any material to the BTM SEAL ALPHA HYBRID TRANSPARENT and thinning before.

    • Firstly, expansion joints, dilatation and water expenses must be checked and combinations thereof shall be provided with BTM SEAL ALPHA HYBRID TRANSPARENT. 

    • Wall floor joints such as the formation of cold joints should be splaying with suitable materials.

    • BTM SEAL ALPHA HYBRID TRANSPARENT must be applied two coats.

    • 12-24 hours after the first coat is applied, from the other direction to the first application layer, the second layer should be applied.
