S-1 and Titanium are extremely effective in preserving and prolonging the service life of all woods, concrete, metals and fiberglass reinforced polyester. Both are two component 50% solids epoxy/polyamide penetrating coatings. They are specially formulated to allow all solvents to evaporate before curing to ensure a complete waterproof barrier to inhibit rot, rust, freeze-thaw damage and osmosis. S-1 and Titanium contain internal rust inhibitors as that provide a tough barrier against moisture to preserve metals and alloys from oxidization, stains and tarnish. They are suitable for interior and exterior finishes above and below the waterline. Use S-1 when you want a brilliant clear finish. Titanium is bright white and tintable. Both are excellent undercoat primers for most paints and clear finishes. To ensure maximum adhesion, sand lightly but thoroughly to a uniform dull finish before applying latex, enamels, more epoxy, varnish, polyurethanes or bottom paints. When used as an exterior clear finish over wood, S-1 must be over-coated with varnish or a suitable polyurethane to protect the surfaces from ultra violet rays. All unprotected epoxies will eventually transform from high gloss to semi-gloss if continuously exposed to sunlight. Wood - Use S-1 & Titanium as a clear or white epoxy paint, interior clear finish preservative, or exterior primer-sealer under paints and varnish on small boats and yachts. Use as a fine furniture finish or preservative sealer for wooden foundations, doors, windows and sashes. An excellent sanitary sealer for wooden hot tubs, kitchen counters and floors. Wooden tools, toys, fishing rods and pool cues. Metal - S-1 & Titanium protect metal against structural damage from salt water and most other corrosive environments. Concrete - Both products penetrate concrete to end dusting, staining, spalding and seeping. They resist gas, oil, transmission fluid, salt and cleaning solutions. Excellent for concrete floors in factories, garages, basements, retaining walls, concrete foundations, pipes, tubs and ponds. These products are also excellent for ferro cement boats, barges and yachts, as well as kitchen counters, bird baths and sculptures. Fiberglass Reinforced Polyester (FRP) - For maximum water and chemical resistance, FRP should be sealed with an epoxy suitable for underwater. Regular fiberglass resin (polyester) contains water soluble consituants which can over time dissolve, resulting in softening, weight gain, cosmetic and structural degradation. Both are effective in minimizing the damage caused by water on FRP boats and other FRP structures subject to constant submersion.
