WOOD WISE FEATURES Keeping timber in tiptop shape By Rystix Timber is a fantastic building material for both interior and exterior. There are important maintenance requirements to ensure that timber lasts long and to keep the beautiful finish. Rystix shares some tips for timber maintenance. CARE AND MAINTENANCE FOR OUTDOOR WOOD An exterior sealer, which includes a solvent-based alkyd resin, is ideal for outdoor timber. The solvent- based sealer penetrates the wood cells and contains special agents to prevent surface dry rot, insect and fungus attack. It also offers protection against the sun’s harsh UV rays. Because it is not a varnish, the exterior sealer does not peel or flake. Future maintenance after the exterior sealer has been applied is simple as it requires cleaning, rinsing and recoating the surfaces. Most exterior sealers are available in translucent colours. Another useful tip for maintaining outdoor wood is by coating it with a water-based sealer. Water-based sealers create barrier layers that protect the wood against the harsh effects of UV rays. Unlike solvent- based coatings, a water-based coating also provides surface protection against moisture and is more abrasive and scratch resistant. This coating is ideal for all areas which are exposed to the weather www.timberiq.co.za // DECEMBER 2019 / JANUARY 2020 43 // DECEMBER 2019 / JANUARY 2020 43
