Many times various stains from dirt, rain, mould or even cement or plaster residues spoil the natural appearance and beauty of stone. An immediate solution to this problem is the powerful acidic cleaning liquid K-38 from New Line, which effectively cleans any natural stone surface.
Surface preparation
First, the surface is cleaned of dust, soil, etc. Removal of any construction debris is done at least 15 days after grouting is completed.
Method of use
The cleaner is applied to the surface followed by scrubbing with a hard broom. Allow to act for 3-5 minutes and rinse with plenty of clean water. For very dry or difficult coatings such as soil, cement, rust, the liquid can be used undiluted or diluted up to 30% with water for milder coatings.
