S-1 is a two-part transparent epoxy sealer. 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.
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.
