Dyebrick is effective in colouring certain types of stonework.
However, trials must be carried out on a small area first to assess the suitability and compatibility with your particular masonry.
Some stone types are very porous and also have high psv's (polished stone values) which make them difficult to tint effectively.
PLEASE NOTE: The Dyebrick Lifetime guarantee only applies to brickwork and does not apply to stonework. Masonry treated with Dyebrick can be sealed with most proprietary sealers when using on these surfaces.
