How do I strip a fiberglass door to restain/repaint it?
To strip a fiberglass door, you'll want to use a methylene chloride-based stripper. We recommend Dad's Easy Strip™, Big Tough™, or Bix Stripper™. Follow the directions on the product purchased. Use a brass wire brush, a medium hard nylon bristle brush, or grade 000 or 0000 steel wool to remove the residue. Do not leave stripper on raised moldings or panels any longer than 2-3 minutes. (Please refer to the Therma-Tru Finishing Instructions.) Paints, stains or topcoats can be removed this way.
The stripper label says “Not for use on fiberglass”. Why do you say it is okay?
Fiberglass doors manufactured by Therma-Tru are made from a material that you can use the recommended strippers on. Again, follow our Finishing Instructions for stripping.
Do you have a kit for refinishing, containing strippers and brushes?
No. Stripping materials have to be purchased separately. See your local Lowe’s store for more details.
