You can paint your fiberglass windows! Here is a guide and tips to help you do that.

How to Paint Fiberglass Windows

Before you start to paint triple or double-pane glass windows, there are a few things to gather:

  • Fine wet sandpaper
  • Epoxy paint
  • Solvents
  • Eye and hand gloves
  • High volume low-pressure spray gun
  • Paint and nose filters
  • Paint stirrers
  • Primer

Next, check the temperature and humidity. The relative humidity should be less than 60%, and the temperature should be between 65 and 90 degrees Fahrenheit.

This is necessary to prevent water droplets from getting trapped in the paint, resulting in a dull finish. Also, if water droplets get into the fiberglass, they can delaminate the glass.

Follow these steps once you’ve confirmed the condition is suitable.

Sand the surface

You must first prepare the surface. This is arguably the most crucial part of the process, so be thorough and do not skip it. If the feeling is too greasy or sticky, the paint won’t stick evenly to the window.

Use the fine wet sandpaper to rough up the surface just enough for the paint to have something to stick to.

Apply the primer

The primer will serve as a bond between the finishing paint and the surface of your fiberglass window.

There are no rules. You can apply it heavily on the windows.

Spray paint

Before spraying, wear your nose filter and gloves to avoid inhaling products that may harm your lungs.

Use the stirrer to stir the paint before filling the spray gun. At low pressure, paint the window by moving the spray gun evenly all over the window.

Start from the middle and move slowly to the outer edges. Maintain some distance between the window and the nozzle to achieve a uniform appearance.

Apply the second coat

After applying the first coat, allow the paint to dry. Then do a light, wet-sanding surface cleaning before applying the second coat.
