Exterior timber, from bespoke oak orangeries to simple garden gates, is under constant attack from the British weather. Between the UV rays of summer and the relentless rain of winter, wood can quickly grey, crack, and rot if it is not properly protected. At Thirsk Decorating Centre, our heritage is rooted in woodcare, and we have put together this professional guide to help you achieve a long-lasting finish.
Step 1: Identification and Assessment Before you pick up a brush, you must identify your timber type. Hardwoods like Oak, Iroko, and Teak are dense and naturally oily. These often require penetrating oils rather than surface coatings. Softwoods like Pine, Cedar, and Larch are more porous and prone to bleeding resins, which means they require specific primers or specialist stains to prevent discolouration.
Step 2: Professional Preparation Preparation is ninety percent of a successful woodcare project. Use high-quality abrasives like Mirka or Indasa, which are available in our Decorating Supplies section, to remove old, flaking finishes and UV-damaged grey wood fibres. If you do not reach fresh wood, your new coating will not adhere properly and will likely fail within a season.
Step 3: Choosing the Correct Coating System We stock two main types of protection. Penetrating oils, such as Osmo Polyx-Oil, soak into the grain of the wood. They do not peel or flake, which makes them incredibly easy to maintain. A simple top-up coat every couple of years is usually all that is needed. Alternatively, high-build stains like Sikkens Filter 7 or Sadolin create a flexible film over the wood. These offer the highest level of UV protection and are ideal for windows and doors where you want a polished, professional look.
Step 4: Application Tips Always apply your chosen finish in the direction of the wood grain. For oils, remember that less is often more. Ensure you spread the product thinly to avoid a sticky finish. For stains, ensure you coat the end grain, such as the bottom of doors or posts, very thoroughly. This is where moisture is most likely to be sucked up into the timber.
