Application steps

MIXING

Stir part A mechanically. When all of part B has been added to part A, mix continuously for 2 minutes until a uniform mix has been achieved and slowly add the part C. Mix until a uniform and lump free consistency.

    

Wall application (vertical surfaces):

In case the thixotropy of the material need to be improved, addition of 0.5 to 3.0% Extender T (Thickening Agent for Resin Systems) is possible. Stir part A mechanically. Add Extender T to component A, and stir for 2 minutes then add component B to A, mix continuously for 2 minutes until a uniform mix has been achieved and slowly add the part C. Mix until obtain a uniform and lump free consistency.

For more details please contact Sika Technical Department.

APPLICATION

Apply SikaCeram® RTG into the joints using a trowel or a rubber squeegee, or pour SikaCeram® RTG onto the floor, raking it out in order to fill the joints and smoothing it off provisionally. After half an hour (at +20 °C), remove the surplus material with Thinner solvent, using a wet sponge.

SikaCeram® RTG can't be emulsified or cleaned with water.

CLEANING OF EQUIPMENT

As long as the product has not hardened, use Thinner solvent for tools and warm water and soap for skin. Hardened material can only be removed mechanically.
