Burgess Marine Woodsealer 1ltr

Burgess Marine Woodsealer is a long‑lasting, water‑based timber treatment designed to protect exterior woodwork from sunlight, salt and harsh weather. Its breathable acrylic formula forms a tough, microporous membrane that seals the timber while still allowing moisture to escape. It helps in preventing cracking, crazing or peeling often seen with traditional varnishes.

Developed by the inventor of Hammerite and trusted since 1987, Woodsealer contains UV‑blocking pigments that help prevent greying and degradation caused by the sun’s rays. It’s ideal for decking, strakes, capping rails, rubbing strakes and any exterior wooden surface above the waterline.

Easy to apply even in damp conditions, Woodsealer dries quickly to a natural matt finish. It can be used as a complete standalone treatment or as a primer beneath Burgess Marine Top Gloss or Marine Clearsealer.
