There are all sorts of monkey wrenches that can be thrown at you on a job:
  • Original color bleeding through
  • Wood grain or other pattern you can't seem to cover
  • A tub bottom that is covered in pits

Our High-Build Primer will take care of all of these problems. Save time, money and frustration. Prime and fix imperfection at the same time. Our High-Build Primer requires no induction time, conveniently mixes with Poly-Glass Regular Dry Catalyst or Universal Catalyst.

If you aren't refinishing kitchen cabinets you should think about it. Cabinet resurfacing can be highly profitable because customers get a totally new look for pennies on the dollar compared to new cabinets or even refacing. With our High-Build Primer, you can get rid of any wood grain to give you a smooth surface for your topcoat. Game on!

Available in White, Gray or Custom Color.

Spray 3 light tack coats so that the tub surface is uniformly coated, but one can see through the coating. After the last coat gets to the tack state, the PolyGlass Topcoat can be applied. The High Build dry film thickness target is 0.8 to 1 mil, while the dry film of the PolyGlass topcoat is in the 2.5 to 3.5 mil range.

Surface Preparation:
This High Build Primer requires the bathtub be prepared to accept the primer by etching with NAPCO Extra-Strong ETCH or our NEW Piranha Prep. The primer must be applied to a dry surface with all the loose etch material be removed by like sanding. For cabinetry, sand with 80 grit sandpaper so no waxy lacquer or stain is on the surface prior to spraying the High Build Primer.

WARNING: This product can expose you to Crystalline silica, Titanium dioxide, Toluene, and Ethylbenzene which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to
