DevoNatural Finish grijzend mat - Vergrijzende, slijtvaste matte parketvernis voor parketplanken en plankenvloeren op basis van watergedragen polyurethaan-acrylaat met UV- en tannineblokker.This anti-yellowing, elastic and sealant water-based interior finish gives unstained wooden floors a natural grey appearance and adds a “faded” look to darker wood types and wooden floors stained using DevoNatural Colour. Indoors, DevoNatural Finish Greying Matt can also be applied to wooden doors, furniture, ceilings, etc. For wooden floors, only apply the product to bevelled parquet and conventional wooden floors. The “faded” appearance depends on the tannic acid content of the wood. Do not use on merbau wood!
