HG cement film remover (product 11) removes cement film from all types of porous and non-porous ceramic tiles and tiles. But also from non-calcareous natural stone types, such as Norwegian slate, granite and quartzite. The unique thing about this product is that it dissolves the cement from the tile surface, but not the cement from the joints. The joints are even reinforced. When it comes to really stubborn contamination, we recommend HG cement & mortar residue remover (product 12)

Dissolve HG cement film remover in water. Pre-wet the surface to be treated with clean water. Then apply the solution liberally using a mop or mop. Do not treat more than 10 to 15m² at a time. Then scrub the surface well with a scrubber or brush. Let it work for 15 to 20 minutes and keep the floor wet with the solution of this product during the working time. Then scrub the treated surface well again. Then remove the solution with a mop and then mop the floor with clean water.
