How to Apply 8721g-g Mega Gloss?

Before applying 8721g-g Mega Gloss, you need to prepare the surface properly. Here are the steps you need to follow:

  • Water blast the surface to remove all loose paint, dirt, oils, and grease.
  • Abrade the surface with 240 grit dry sandpaper or equivalent to create a smooth and even surface.
  • Solvent wipe down the surface to remove all sanding residue.
  • Prime the surface with Mega Gloss Primer 8735 for best results.

After preparing the surface, you can apply 8721g-g Mega Gloss with a brush, roller, or spray gun. Here are some tips for each method:

  • Brush: Use a good-quality synthetic bristle brush. Apply thin and even coats in one direction. Avoid over-brushing or re-brushing wet paint.
  • Roller: Use a 3/8″ – 1/2″ nap mohair metal, lambskin, or phenolic core roller. Keep the roller wet and roll in one direction. Rewet the roller and cross-roll for better coverage.
  • Spray: Use a conventional air gravity feed spray gun with 59-70 psi pressure and 0.055 – 0.070 tip size; or an airless spray gun with 2200-2500 psi pressure and 0.013 – 0.017 tip size. Hold the gun perpendicular to the surface at a distance of 10 – 12 inches. Apply thin and even coats with overlapping strokes.

For best results, apply two full coats of 8721g-g Mega Gloss at a recommended dry film thickness of 4 mils per coat. Allow at least four hours of drying time between coats. Lower temperatures and higher humidity will slow down the drying time. Do not apply the product if the material, substrate, or ambient temperature is below 50°F or above 95°F.
