KASTONE® Grouting, a sand-based grouting used to fill and support joints between stones and bricks during installation, enables you to achieve the ultimate authentic look for your brick and stone walls.

This material is formulated with coarse silica sand, synthetic resin, colour pigments and water retentive additives. KASTONE® Grouting also retains compressible properties which allows it to expand and retract in accordance with its surrounding stones due to environmental factors (i.e. heat).
