Directions for use: apply evenly with a brush, sponge or cloth to a dry, clean surface. Wipe off excess. Wait a few seconds, then wipe and polish the surface thoroughly with a dry cloth or felt. We suggest re-impregnating the surface after 10-15 minutes. After impregnation, do not walk on the surface for 24 hours. For the first application, try on an unnecessary piece of material or on the invisible side of the product. 1L is sufficient to impregnate ≈ 20-40 m2 (depending on the porosity and absorbency of the material). Shelf life at room temperature 2 years.
