Wood Sealer
Bare or knotty wood needs a little prep before it'll hold a finish properly. That's where a good wood sealer comes in. The range at Trade Supplies UK lays down a protective base that keeps moisture out, locks resin in, and gives your paint or varnish something solid to grip — so the finish looks great and lasts a lot longer.
Why Sealing Timber Matters
Skip the sealer and wood tends to soak up water, let knots bleed through your paint, and wear out faster outdoors. A quick coat of sealant takes care of all of that:
- Stops sticky knots showing through — no more sap stains ruining your paintwork.
- Keeps water out — helps prevent swelling, warping and rot.
- Helps paint stick better — gives topcoats a smooth, stable base.
- Makes timber last longer — protects wood inside and out.
Sealing Knotty Wood the Right Way
Knots are the usual troublemakers — they leak sap that discolours and lifts paint down the line. The Blackfriar Patent Knotting is built exactly for this. It seals knots and resin spots so they stay tucked away under your finish, leaving doors, joinery and trim looking clean and professional.
Built for Outdoor Conditions
Wood that faces rain and damp really needs a waterproof wood sealer. Sealing before you decorate helps shrug off water, cuts down on cracking, and keeps outdoor timber looking good all year round.
