Coregal TER wood saturator 5L - Decking & outdoor timber

For large-scale outdoor timber projects that demand lasting, professional-grade protection, Coregal TER wood saturator 5L is the go-to solution for homeowners and professionals alike. Its advanced water-based formula combines powerful weatherproofing performance with a respect for the natural beauty of the wood — in three versatile shades to suit every project.

Suitable for a wide range of timber species
Unlike many wood treatments formulated for a single timber type, Coregal TER 5L is versatile enough to protect pressure-treated (autoclave) timber, naturally resistant species and exotic hardwoods — making it the ideal all-in-one saturator for mixed outdoor installations featuring different wood types. One product, total coverage across your entire project.

Triple-action protection against the elements
Coregal TER's advanced formula delivers comprehensive protection on three fronts simultaneously. Its hydrophobic action repels water and prevents moisture ingress, protecting the wood structure from swelling, cracking and decay. Its UV-filter technology significantly slows the natural greying process caused by prolonged sun exposure. And its deep-penetrating, non-film-forming formula nourishes the wood from within — without trapping moisture or creating a surface coating that can crack or peel over time.

A breathable, matte finish that respects the wood
Coregal TER penetrates deep into the timber fibres rather than forming a surface film — preserving the authentic texture, grain and natural appearance of the wood while allowing it to breathe naturally. The result is a clean, understated matte finish that enhances the wood's character without altering it. Clear shade maintains the original timber tone; honey adds warm golden tones; brown delivers a richer, deeper finish.

Perfect for large surfaces — 5L for maximum coverage
The 5L format is specifically designed for large outdoor timber surfaces, significantly reducing the number of applications required and offering excellent value for money on sizeable projects. Ideal for decking, cladding, pergolas, slatted surfaces, gates, fencing and garden furniture — wherever extensive timber protection is needed.

Easy application and fast drying
Simple to apply by brush, roller or low-pressure sprayer, Coregal TER dries quickly to minimise downtime between coats. Tools clean up easily with water after use — no solvents required. For porous or weathered timber, a second coat is recommended to ensure full penetration and maximum protection.

Application tips
Apply to clean, dry timber only. A second coat may be required for particularly porous or aged surfaces. Reapply 1 to 2 times per year depending on exposure and use to maintain long-lasting protection.
