D-7 Natural Stone Cleaner 1Lt / 5Lt DUROSTICK

Powerful cleaner that effectively removes building debris from natural stones, restoring their original appearance. Deeply cleans accumulated dirt, salts, mud, blackheads, mold as well as stains from oil, coffee, rust and non-solidified plastic paints. It does not affect the natural appearance of the stones or joints and ideally prepares the surfaces to be waterproofed or decorated with varnish. The cleaning should be carried out after 28 days from the grouting.
