HG stain protector (HG product 15) is suitable for both porous and non-porous ceramic tiles and natural stone floors, and provides invisible protection against staining and penetration and sticking of dirt, so that your floor becomes clean again simply by mopping. Even the most porous surfaces are protected deep into the pores. It is therefore ideal for use in the living-room, kitchen, bathroom, etc. First clean ceramic tiles using HG tile power cleaner (polish, wax and dirt remover) (HG product 19), and clean natural stone using HG natural stone power cleaner (stripper) (HG product 40). Then generously apply this product with a paintbrush or roller. If the surface is very porous, a second treatment is recommended. 1 litre is sufficient for 100 m².
