D-7 DUROSTICK NATURAL STONE CLEANER
Powerful cleaner that effectively removes building debris from natural stones, restoring their original appearance. Deeply cleans accumulated dirt, salts, mud rain, tarnish, mold as well as stains from oil, coffee, rust and uncured plastic paints. It does not affect the natural appearance of stones or joints and ideally prepares surfaces to be waterproofed or decorated with varnish. Cleaning should be carried out after 28 days of grouting.
