Epifanes Polyurethane may be applied directly to clean degreased and sanded (to 220 grit) Gelcoat, Epoxy, and surfaces previously painted with two-part polyurethanes. If the surface has scratches and pinholes apply two coats of Epifanes Epoxy Primer, and sand to 220 grit before painting.
Pour the small hardener can into the larger paint can and stir well; allow the mixed paint to sit for 30 minutes before using. If you have leftover mixed paint put the lid back on and it should be usable for at least 6 hr. Add about 5% Epifanes Polyurethane Brush thinner, and pour into a solvent-resistant paint tray. Start at an edge or corner and use a soft foam rounded end (European) roller, roll in one direction until the roller is out of paint (about 2’ x 2’), cross roll with the dry roller. Do not try to cover in one coat, you will get runs. Immediately drag over the fresh paint once with a 4" foam brush, use only the high-density ones with the wooden handle. Load the roller and repeat slightly overlapping the previous panel with the brush when tipping out. Do not try to brush the paint out; streaks from tipping will flow out on in a few minutes or be covered with the second coat. If the brush drags or squeaks add thinner to the mixed paint, the brush should move over the paint easily. Keep moving around the boat and try not to stop until you are finished or reach a corner. If the first coat goes on satisfactorily you may apply a second coat without sanding when the paint is touch dry, about 4 hours up to 12 hours. If necessary you can sand after 24 hours and apply the next coat. Apply a third coat if needed. Minor flaws in the final finish can be buffed out.
SPRAY APPLICATION
Epifanes Polyurethane can be sprayed using Epifanes Polyurethane Spray Thinner. You should have a professional quality gun with the proper tip and some experience spraying 2 part paints. Epifanes Polyurethane is designed for DIY roller brush application and will achieve as good as or better results than spray.
REPAIRS TO TWO-PART POLYURETHANE PAINTS
Repairs can be made by sanding the damaged area plus about a 6" border with 320 grit dry or 600 wet. Only take the gloss off the surface of the paint in the border areas. Apply 2 or 3 coats of paint feathering the edge toward but not into the unsanded surface. You can mask the area, but do not paint over the tape. Allow the paint to dry for two days, then wet sand by hand using a soft rubber pad with 400, 800, and 1200. Blend the new paint into the old, be careful not to sand through. Finish by buffing with rubbing and finishing compounds designed for two-part paints.
APPLICATION TIPS
PREPARATION: Finish and durability is only as good as the prep work. Attention to detail, use of proper techniques, and materials will produce superior results. If you can see flaws in priming and filling you will see them in the finish.
WEATHER AND WORK SITE: Optimum application temperature for these products is 200C /700F; avoid painting below 120C/55F and above 300C/85F. At low temperatures, condensation can cause adhesion problems as well as loss of gloss. To check the dew point, wet a small area with water, if it dries in 15 min it is OK to paint. At high temperatures, the paint will not flow properly. Do not paint in direct sunlight, when it is windy or when it is raining if you are in an unheated shop. A covered area is best, but working outside will is OK if you wait for the right day.
BEFORE YOU PAINT: Remove sanding dust with a hose and a cotton cloth, the water should sheet off. Let dry and wipe down with Epifanes Fiberglass Prep Cleaner. Just before painting wipe lightly with a tack cloth. About 2 hours before you paint wet down the surrounding area floor and keep it wet. If you are in a dusty shop it helps to hang a new sheet of polyethylene plastic about 7’ over the deck. Wear a new paper suit with a hood, elastic cuffs, rubber gloves, and a carbon filter mask. Have tweezers handy to pick out bugs etc.
TAPING: Use Fine Line tape for a sharp no bleed line, double mask with low tack tape. Remove tape when the paint is tack free or within 12 hrs. When removing the tape pull away from the paint at a 450 angle.
