Fiberglass
Fiberglass consists of finely spun fibers cast into epoxy, resin, vinyl ester, or thermoplastics. It is a popular material in building and industrial applications for its strength. Before painting, lightly sand (abrade) and degrease.
With Acrylics or Oils, paint directly on the surface or prepare with desired ground.
With Watercolors and Dry Drawing Medias, we recommend a commercial bonding primer or gesso as a base coat. Always follow the manufacturer’s recommended preparation.
Oils and Acrylics can be painted directly on this preparation.
Watercolors and Dry Drawing Media can be utilized on top of an appropriate acrylic preparation like a pastel or watercolor ground.

Hi there,
I am hoping to create an over sized, 3d, hanging moon light for an event i have coming up.
I know you recommend priming, but would the light still shine through if we did this?
Would watercolours work without a primer?
If not, what process would you recommend to enable to the light to be visible.
Thank you, Laura
Hello Laura,
Fiberglass is too smooth and non-absorbent of a surface to paint on directly with watercolors. You could use High Flow Acrylics for water-color like effects, or use a thin layer of QoR Watercolor Ground. This should still let plenty of light show through. Testing on a sacrificial piece of fiberglass would be ideal.
Is cutting and/or painting on fiberglas toxic? Does one have to seal the edges after cutting? Does one have to wear a mask when cutting?
Hello, Heide.
Thank you for your questions. We’ll answer this and your follow-up question in this response.
Fiberglass panels and other substrates are made from fiberglass fibers and resin. Most of the concern is when creating the panels, but as you mention, if you are planning on cutting the panels, or cutting on top and onto the panels, or sanding the surface, this is when you will want to have personal protective gear, as the airborne fibers and dust is dangerous. Fiberglass is usually primed with a commercial primer such as automotive primers. Then you can apply artist materials as desired. Acrylic paints and mediums are very receptive to these primers, and there’s no adhesion issues to worry about, but if you plan to display these outside, a clear coat that has UV Protection is advised. Ideally, “sandwich” the acrylic and collage layers between the automotive primer and a compatible urethane topcoat to prevent moisture from making its way to the decorative layer. If you have any additional questions it may be best to contact us directly at [email protected].

another question – can one adhere paper, as in collage, with Matte or gloss medium to fiberglas?
