How to Take Paint off Fiberglass

Many patio doors consist of fibreglass. Painting over fibreglass is effective because of the way paint adheres to the material. Apply paint properly on fibreglass to ensure that the surface is not gummy and blotchy looking. Chemical paint strippers remove gummy paint from fibreglass without a lot of effort. Always refer to the instructions on the back of the paint stripper to ensure proper use.

  1. 1

    Use chemical paint stripper to remove the paint from the fibreglass. Pour a cup of paint stripper into a metal can.

  2. 2

    Dip a paint brush into the paint stripper and brush a section of the fibreglass. The paint stripper takes about two to three minutes to dissolve into the paint.

  3. 3

    Scrape the paint from the fibreglass with a utility or putty knife. Gently scrap the surface to remove the paint and be careful not to scrape off the fibreglass material. Brush the area with a nylon brush to remove the stripper paint.

  4. 4

    Repeat the steps to remove remaining paint from the fibreglass. Wash the area with alcohol and a sponge to neutralise the chemical stripper. Inspect the area completely to make sure the paint stripper is completely removed.

  5. 5

    Wipe away any residue with a cotton rag. Wait for the fibreglass surface to dry. It may take up to two hours to dry completely. Sand the area with fine 1500-grit sandpaper to smooth over the area prior to repainting.
