TruCoat Fiberglass Door Stain Kit

TruCoat fiberglass door stain is a high-performance fenestration coating that has been exclusively developed for staining wood grain fiberglass door slabs.  Our door stain kits include two stain components.  A solid pigmented stain for filling the wood grain and a transparent topcoat.  The grain filler and topcoat are the exact same product, except for the pigment, which ensures perfect adhesion to each other.

TruCoat Stain combines the optimal performance characteristics home owners, contractors and manufacturers have been seeking:

  • Exceptional adhesion and surface hardness
  • Long-term color fastness and fade resistance
  • Ease of application and cleanup
  • Low VOC and environmentally friendly

Each door kit has enough stain to cover both sides of a 3/0 x 8/0 solid fiberglass door. We offer TruCoat stain kits in 4 standard stain colors. Each fiberglass door stain kit can be applied in different strengths to achieve a variety of light and dark finishes. TruCoat can be applied with a foam brush or HVLP spray gun with a 1.7 mm tip or larger. Included with each door stain kit is:

  • 1 quart of base
  • 1 pint of grain filler
