For Wood: S-1 seals effectively against moisture and oxygen, helping to protect against wood rot. It is ideal for yacht interiors, shelving, cabinets and furniture. For Concrete: S-1 is an excellent moisture barrier for concrete surfaces. For Metals: S-1 helps to prevent oxidation and chemical exposure effects including staining and tarnish. For FRP (fiberglass): Coat polyester laminates with S-1 to provide complete moisture resistance that the fiberglass by itself cannot provide. Use as a first sealer step in gelcoat blister repair, after the blisters have been ground out.
