HG natural stone protective coating gloss finish (product 33) is a unique and easy to apply polymer emulsion. After drying, this emulsion forms a shiny, extremely thin but strong protective film. This protects the top layer of the natural stone against wear and damage by acids, such as soft drinks and wine. This protective film for natural stone also has an anti-slip effect. 1 litre is sufficient for approximately 60 to 80m2 per layer. This product is also available as a mat version..Dilute HG natural stone protective coating gloss finish 1 on 1 with cold water. Pour the solution over the floor and spread it in one direction over the natural-stone floor with a wax spreader or roller. After about 40 minutes, a second coat can be applied crosswise onto the first layer.
