RANANOSEALER offers an excellent water repellent and stain resistant finish for natural stone, clay, marble, mineral based plaster and concrete. It is ideal to bond friable surfaces.

Surface Preparation

All surfaces should be clean, dry and free of dust and debris. Any surface contaminants like grease and oil must be removed.

Apply two coats directly one after the other, this “wet on wet” method is vital to ensure adequate protection. No more than 15 minutes should pass between first and second coats.
