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
