Exterior Surfaces of Stained Steel Doors and Fiberglass Doors
Stain must be thoroughly dry. Do not sand uncoated stained surfaces.
Sand smooth using fine sandpaper and vacuum any sanding dust.* Wipe using a tack cloth to remove any remnants of dust prior to application. Do not use steel wool. If open-grained woods are to be filled, use a filler that does not contain stearates or waxes, such as ZAR® Wood Patch or ZAR® Trowelable Wood Patch.
Old Finishes in Good Condition
Remove grease, dirt, and wax.* Sand lightly in the direction of the grain to remove any gloss. Do not use steel wool. Vacuum all sanding dust. Wipe using a tack cloth to remove any remnants of dust prior to application. If the old finish contains wax or stearates, regardless of condition, remove it completely. Test ZAR® Exterior Water Base Poly High Performance in an inconspicuous area for compatibility.
Old Finishes in Poor Condition, Lacquer or Shellac
Remove it completely.* Do not use steel wool. Sand and vacuum all sanding dust. Wipe using a tack cloth to remove any remnants of dust prior to application.
Apply when air and surface temperatures are between 60°F and 90°F and the relative humidity is less than 50%. Stirring is not required for ZAR® Exterior Water Base Poly High Performance Gloss. For Satin and Semi-Gloss, stir thoroughly before and during application. Do not shake. Use a clean synthetic fiber or foam brush. Do not apply with a roller. To ensure satisfactory results, always test ZAR® Exterior Water Base Poly High Performance in an inconspicuous area before completing entire job. ZAR® Exterior Water Base Poly High Performance goes on milky from the can, but dries to a rich amber color. Apply thin coats at a rate of 500 – 600 square feet per gallon in the direction of the grain. Do not over brush or trap air bubbles in the finish. Sand lightly between coats (except fiberglass or grained surfaces) with a fine grit sandpaper. Remove all sanding dust with a vacuum or tack cloth. Apply 3 coats.
Note: when staining an exterior door with an interior wood stain, use a quality oil-based stain such as ZAR® Interior Oil Base Stain or use an interior water-based stain. Allow oil-based stains to dry for a minimum of 48 hours. For water-based stains, follow manufacturer’s directions. Do not apply ZAR® Exterior Water Base Poly High Performance over paint.
Exterior durability depends on the amount of exposure to sun and weather conditions. Inspect the finish yearly for signs of wear. If minimal deterioration has occurred and no visible damage is detected, clean the surface thoroughly, sand lightly with fine sandpaper and apply another coat.
Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.
Q. Can you use exterior polyurethane indoors?
A. In general, the answer is no. When applied indoors, the product tends to acquire a whitish look. The exception? Feel free to use exterior polyurethane on window sills that receive direct sunlight.
