MAS Deep Penetrating Epoxy Sealer has the consistency of water, letting it soak deep into soft or rotten timber and rebuild it into a hard, workable composite — without cutting out and replacing sound wood.
What it's for
Deep Penetrating Epoxy Sealer is designed to repair wood and GRP without ripping out material and creating extra work. It transforms soft, rotten wood back into a hard composite that can be glued, worked, and finished with any modern paint or varnish. We used it to save every sheet of deck plywood during the restoration of our 1954 Yachting Monthly Junior dinghy — read more in our restoration diary.
Where to use it
Fixing rotten timber, sealing and filling voids, window sills, deck repair, door frames, transom reinforcement — anywhere you need to restore rotten wood. For injecting resin into tight voids, a Terumo syringe gives precise control.
100% solids, no VOCs
Made from 100% solids, with no thinner or solvent to evaporate off, so you get a consistent result every time with no part-cured patches. Like all MAS epoxies, it's also fully waterproof once cured.
Improving penetration
For even deeper penetration, the mixed resin and hardener can be diluted with an equal amount of denatured alcohol or a paint solvent such as lacquer thinner — this can improve penetration by up to 100%.
Specification
