Instructions for use: dry the stone in a kiln or in the open air after it has been polished to #800 grit. Air dry for 1-2 days to allow the moisture absorbed during grinding to evaporate completely. Apply the impregnant evenly (by hand or mechanically) so that a slight excess of material (approx. 50 g/m²) is formed. Allow the product to dry (48-72 hours). Polish the dried stone using only a polishing tool. Water, dust and dirt can adversely affect the result. For the first time, try on a piece of material that is not needed or on the invisible side of the product. Shake before use. Shelf life at room temperature 2 years.
