Epoxy over Painted Wood
Water based paints are best and fast drying. The epoxy can go over them in about 24 hours. OIL BASED paints take a LONG time to fully dry. If an oil-based or oil-modified paint is used, you must apply 3 coats of oil-based polyurethane to seal the surface before applying a seal coat of our UltraClear epoxy. If you go directly over the oil-based paint and it is not completely dry, you run the risk of the epoxy not sticking to the surface and peeling off months later. Acrylic paint dries faster and is safe to use the epoxy on. You would still need to do a seal coat after your paint dries.
The seal coat is a small batch of epoxy that is brushed on in a thin layer to seal any pores in the surface and prevent air bubbles from forming in the following flood coat. Our epoxy is used for both your seal coat and your flood coat. You do not need a different product. Both seal and flood coats are always a 50/50 mixture. For the seal coat, mix up a small batch (16 oz. of Resin + 16 oz. of Hardener) and use a very good paint brush (around $10 at the home improvement store) to apply to surface. You will paint it on just as you paint on a wall. This stage is followed by the flood coat , which will flow and self level to 1/8".
