RB-CAL 500 can be used on all hard, clean, dry or slightly wet surfaces. Surfaces with insufficient strength and defected areas must be repaired and cleaned before application. Heaved areas must be cleaned with mechanical measures. The regions, on which no APPLICATION will be carried out, should be protected. The subfloor must be protected against negative side humidity. Due to its gloss, it should not be used on facades (wall) impregnation.

Shake the material well before use. Apply it homogeneously on the surface with a plastic (rubber) brush or roller. For indoor joints use a brush. After a maturing time of 5 minutes, remove the excess material. One application is sufficient.


Do not use under sunlight and on warm surfaces due to sunlight.
