Product Overview:

Why replace rotten or damaged wood when you can repair it?

MAS Penetrating Epoxy Sealer is a low-viscosity epoxy formulation that penetrates deep into rotten or damaged wood, restoring structure and providing a solid base for additional repairs. It consists of a tough, flexible resin system that chemically adheres to the wood fibers and significantly strengthens them while allowing for normal expansion and contraction.

MAS Penetrating Epoxy System is particularly valuable when damage is limited to a portion of an otherwise sound component; or in cases where the damaged piece would be impossible or too costly to replace. Perfect for projects such as:

  • Window Frames
  • Door Frames
  • Windowsills
  • Deck Repair

Once cured and as good as new, it may be painted or stained.

Features & Benefits:

  • Low viscosity formula penetrates deep into rotten and damaged wood
  • Tough and flexible system restores structure and provides strong base for additional repairs
  • Epoxy be reduced further with common paint solvents to double the penetrating power into damaged wood
  • May be painted or stained
  • Easy to use kits available in two convenient sizes: Size 1 - Pint Resin (A), 1/2 Pint Hardener (B); Size 2 - Quart Resin (A), 1/2 Quart Hardener (B)


The penetrating power of the MAS epoxy resin system is superior to most competing products on the market, but can be dramatically improved by diluting it with common paint solvents such as denatured alcohol, lacquer thinner or acetone. The mixed epoxy and hardener may be diluted with as much as an equal volume of solvent. This simple solution doubles the penetrating power of the MAS penetrating Epoxy Sealer.
