After more than twenty years of dealing with wood rot, it is our experience that stabilizing the remaining material with a penetrating epoxy is the key to a permanent, high strength repair. Done properly, using high quality products, it is our opinion that the resulting repair can equal the strength and durability of replacement. Often at less cost. We are happy to put our decades of experience at your disposal, so that your project turns out to your satisfaction.
S-1 Epoxy Sealer is a 50% solids epoxy/polyamide system. Mixed at a simple 1:1 ratio, S-1 is extremely effective at prolonging the service life of all woods, concrete, metals and fiberglass reinforced polyester. S-1 is ready to use with no thinning required. It is completely waterproof suitable for use above or below the waterline. S-1 is a superb under-coat primer for most paints and clear finishes featuring strong adhesion to most substrates with minimal surface preparation.
S-1 does not require sanding between coats if recoat time is less than 24 hours. It is resistant to salt air and water, mild acids, alkalis, chemicals and solvents. S-1 is not recommended for gas tanks containing unleaded gasoline.
For Wood: S-1 seals effectively against moisture, helping to protect against wood rot. When wood rot does occur, it is an excellent first step in wood rot repair, penetrating deep into the residual deteriorated material. It is an ideal primer on bare wood before topcoating.
For Concrete: S-1 is an excellent moisture barrier for walls and floors. It works well as a dustproofer for floors.
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.

GENERAL SURFACE PREPARATION: Surfaces should be free of dust, grease, oil, wax, and any other foreign matter. Sand with 100-150 grit sandpaper, unless the surface is rotted wood. Use a tack rag to completely remove dust prior to application of S-1.
OVER ROTTED WOOD: Remove loose, well rotted wood if practical. Make sure remainder is dry. Apply S-1 Sealer repeatedly every 10-30 seconds, until absorption stops or slows significantly.
OVER CURED EPOXY RESIN: Sand epoxy substrate with 220 or 320 sandpaper to remove as much of the gloss as practical. Ensure surface is clean and dry then apply S-1. Resin surface may require up to 2 weeks prior to coating for all residual curing agent to be out of the surface.
NEW WORK (BARE WOOD): Apply 1-3 coats, depending on application. If S-1 is going to be exposed to UV light, a durable top coat is needed.
OLD WORK: If previously varnished surface is in good condition, sand and varnish. If old finish is not in good condition, remove and proceed as with new work.
ALWAYS MIX THOROUGHLY!
IMPROPER MIXING IS THE GREATEST CAUSE OF EPOXY SYSTEMS FAILURE.
