As with any natural product, variations in colour, texture and shape may occur. In addition, images may vary slightly from actual products due to these natural variations and screen resolution. For the best consistency, ensure to acquire a sufficient amount of material with your order to avoid batch-to-batch variation.

Suitable for void filling and consolidation of masonry walls, where the binder strength is appropriate for the host background or surface. Not suitable as a tiling or floor grout.
