We highly recommend that you treat all Oak doors, skirtings, lining sets and architraves with a Hardwax Oil, our preferred product is the Hardwax Oil by Treatex. Their range has a higher wax content than comparable products on the market, it is important as this will prevent moisture absortion. As Treatex is a blend of oil and wax, the oil soaks into the wood to enhance the grain and the wax sits on the surface to provide a smooth finish. Treatex is available in a number of natural finishes which all bring out the beautiful grain in the European Oak. Our free samples come with a block of solid oak to show you exactly what it'll look like when you apply it to your new oak products.
