HG cement grout film remover removes cement residue from all types of porous and non-porous ceramic tiles, flagstones and non-calciferous natural stone types such as Norwegian slate, granite and quartzite. The unique aspect of this product is that it dissolves cement from the tile surface but not the cement from the grouting. The grouting is even reinforced!
Dissolve the product in water. First moisten the surface with clean water and then apply the solution generously using a floor cloth or mop. Do not treat more than 10 to 15 m2 at once. Then scrub the surface well with a stiff broom or scrubbing brush. Leave to penetrate for 15 – 20 minutes, keeping the floor wet with the solution of this product in the meantime. After that, thoroughly scrub the treated surface again and then remove the solution with a mop, before mopping the floor with clean water.
