S-1 Sealer is a two-part clear penetrating epoxy sealer (C.P.E.S.). Intended for marine use, it will act as a waterproof and chemical resistant primer on a variety of substrates including wood, concrete, metal, and fiberglass.

Product Features:

  • Simple 1:1 mix ratio
  • Ready-to-use viscosity, no thinning required
  • Excellent wetting properties on most surfaces
  • Applies by brush, roller, or spray
  • Long pot life
  • Waterproof
  • Strong adhesion to most substrates with minimal surface preparation
  • Non-brittle even at extremely low temperatures
  • No sanding required between coats up to 24 hours
  • Resistant to salt air & water, mild acids, alkalis, chemicals, and solvents (not unleaded gasoline-proof)
  • Clear, but may be pigmented


Recommended Uses:

Wood: Seals effectively against moisture and oxygen, helping to protect against wood rot. Ideal for yacht interiors, shelving, cabinets, and furniture.

Ferro-cement boats (reinforced concrete): Excellent moisture barrier for bulkheads and decks.

Metals: Helps to prevent oxidation and chemical exposure effects including staining and tarnish.

FRP (fiberglass): Coat polyester laminates with S-1 to provide complete moisture resistance that the fiberglass laminate alone can't provide. Use as a first sealer step in gel coat blister repair, after the blisters have been ground out.
