Recoating of Polyurethane GacoDeck System Instructions

1. Thoroughly scrub the deck with GacoFlex D-09 Etching Detergent and a stiff bristle broom or brush. Thoroughly rinse with clean water and allow deck to dry completely.
2. Apply by roller one coat of GacoFlex U-66 polyurethane coating in the desired color at the rate of one gallon per 100 square feet (3.78 L / 9.3 m²). Allow to dry a minimum of 48 hours before using.

TO REPAIR DAMAGE SUCH AS CUTS, BURNS, RUPTURED JOINTS, REPAIR AS FOLLOWS:

1. Remove loose coating. Sand damaged area, feathering edges. Sand ruptured joints to a minimum of 4” (10.16cm) wide. Remove loose or popped nails and re-nail with hot dipped galvanized or non-rusting ring shank nails. Fill old nail holes with tapered wood plugs driven flush with deck surfaces.
2. To repair damage to a plywood or concrete substrate, polyurethane caulking can be used or prepare a leveling grout by combining one part GacoFlex U-66 Polyol and one part GacoFlex U-66 Iso with one part 80 mesh sand. Apply grout to fill voids and allow to dry firm (6 to 24 hours).
3. Coat repair areas with one coat of GacoFlex U-66 polyurethane, feathering out an adjacent surface. Allow to dry until coating is firm enough to walk on.
4. Repair ruptures or cracks by installing 66B tape and coat with GacoFlex U-66 polyurethane. Allow to dry until coating is firm. (Usually 4 to 12 hours.)
5. Apply a light coat of GacoFlex U-66 polyurethane and distribute GacoShell to reestablish texture as necessary in damaged areas.
6. After the GacoShell granule coat has dried overnight, remove excess granule and check for continuity of texture.
7. Apply one coat of GacoFlex U-66 polyurethane in the desired color over the deck at the rate of one gallon per 100 square feet (3.78 L / 9.3m²). Allow this to dry a minimum of 48 hours before using.

   NOTE:Variation in drying times is due to weather differences.

For best appearance, GacoDeck should be washed as needed to remove natural soil accumulation. This is best done using GacoFlex D-09 cleaning solution. Wash and water rinse. For general cleaning and maintenance, mix as required up to 9 parts water to one part D-09. This procedure will maintain natural color during many years of service.
