Does not react with water, does not mix with water, solvent-free, binds non-porous surfaces, tough, long-lasting, does not flow down (ideal viscosity).


• Two-component, colorless, low viscosity, solvent-free, epoxy.

Preparation data:

EpoStone may not come into direct contact with water or chemicals during application and curing (do not apply in the rain!). The substrate, moreover, may not contain substances soluble in water such as salts, solvents, etc. For heating the space during application, do not use oil burners, gas burners, etc., producing CO2 and water vapor in the location, which have a negative impact on the quality of the surface.
