HG tile protection impregnation (HG product 13) is a special basic treatment for (new) unglazed floor tiles. This unique product lifts the absorbent effect of the floor and prevents dirt and grease. The original character of the tile is retained and the floor is not sealed. The product is suitable for all porous and slightly porous tiles and can be used indoors and outdoors. Apply the liquid evenly in one direction with a paint roller. Then leave to soak for 10 minutes and remove excess liquid with a dry, lint-free cloth. Depending on the type of soil, 1 litre of this product is sufficient for up to 40 m2 floor area.
