SpecWood®
WB Acrylic Deck & Wood Outdoor
SpecWood® WB Acrylic Deck & Wood Outdoor is a one-component, water-based, self-crosslinking acrylic topcoat formulated for exterior timber, joinery and decking. Highly flexible and weather resistant, it provides excellent protection against water and abrasion while accommodating the natural movement of timber. Available in transparent, natural wood-shade and solid RAL colours, it provides durable protection without compromising the desired appearance of the wood.
Pack size: 5L & 20L.
Features & Benefits
- Excellent exterior durability
Self-crosslinking acrylic technology provides very good resistance to weathering while maintaining film integrity. - Highly flexible film
Moves with timber as it responds to changes in temperature and moisture, helping reduce cracking. - Very low water absorption
Helps protect exterior timber against moisture penetration and weather exposure. - Abrasion resistant
Provides the mechanical durability required for outdoor timber, including light- to medium-traffic decking. - Excellent liquid resistance
Demonstrated resistance to liquid water, salt water, ethanol, coffee and red wine. - Three finish options
Available in Gloss (>90 GU), SilkMatt (20–25 GU) and Matt (5–10 GU). - Consistent performance across sheen levels
All three finishes use the same base resin platform, providing equivalent weathering performance and film integrity. - Transparent clear option
Protects timber while retaining its natural appearance. - Natural wood-shade finishes
Transparent iron oxide pigmentation provides colour while allowing the natural grain to remain visible. - Solid RAL colours
Allows a complete colour transformation where the natural timber appearance is not required. - Excellent blocking resistance
Helps prevent coated timber components from sticking together. - Mould and algal resistance
Incorporates a synergistic biocide system based on silver and BIT chemistry for in-can preservation and film mould and algal resistance. - Water-based formulation
Low odour with convenient water clean-up. - Suitable for demanding interior surfaces
Can also be used on interior wood feature surfaces requiring high mechanical and chemical resistance. - Developed for local conditions
Manufactured in South Africa and formulated for the South African climate, with a full RAL colour-matching service available.
