Frequently Asked Questions

How do I get a perfectly flat UVPoxy coating on top of a wood surface?

In order to obtain a perfectly flat and level epoxy coating, the surface under the coating also must be flat and level. Natural features in wood surfaces, such as knots, cracks, and areas with larger pores, can absorb more resin than surrounding areas. This results in indentations and low spots. If your work surface has any of these features, 2-3 seal coats may be required to fully seal the surface. Apply the first seal coat, sand with 220 grit sandpaper, and wipe down. Examine the surface carefully to confirm that all voids have been filled and the surface is flat. If this surface is not smooth, seal coat and sand again, repeating as many times as required until the surface is perfectly flat and level. Then, continue to the flood coat.

Can I use a Power Mixer to mix UVPoxy?

Using a power mixer is not advised. UVPoxy should be mixed by hand. Mix with a stir stick and stir deliberately, but do not whip the resin. Doing so introduces excess air into the mixed resin, which makes it difficult to achieve a bubble-free final project.

Will my UVPoxy project yellow over time?

All epoxies yellow over time. To combat this, we formulated UVPoxy with UV stabilizers. These additives absorb UV light and prevent damage to the resin. Eventually, the stabilizers will lose their effectiveness. Adding metallic or liquid pigments to UVPoxy will help it resist yellowing better than if it is left transparent. Completed projects should not be kept outdoors.

Do I need a seal coat for UVPoxy? What product do you recommend?

We recommend seal coating any surfaces that will be coated with UVPoxy. Once cured, seal coats help prevent air and moisture from migrating out of substrate materials, which can cause bubbles. UVPoxy is the preferred system for seal coats.

Can I apply a coating thicker than 3.2mm (1/8”)?

We do not recommend attempting to apply UVPoxy coatings greater than 3.2mm (1/8”). Thicker applications will cure too quickly to allow air bubbles to rise to the surface. To achieve a thicker coating, applying multiple layers of UVPoxy is recommended.

Can I apply UVPoxy in multiple layers?

Yes, UVPoxy can be applied in multiple layers. Additional layers should be poured when the previous layer has reached set to touch. To prepare the epoxy surface for the next layer, scuff the surface with 220 grit sandpaper. Remove excess dust and debris, then wipe clean with denatured or isopropyl alcohol. You can then pour the next layer.

What kind of projects can I use UVPoxy for?

UVPoxy can be used as a clear coating or be pigmented and used to create fluid art using techniques such as:

  • Dirty Pour
  • Beach Scenes
  • Marbling
  • Florals
  • Swipes
  • Dutch Pour
What is the difference between UVPoxy and FlowCast®? What do I need to keep in mind when using UVPoxy?

UVPoxy is a coating resin, while FlowCast is formulated to be used for large castings. Like FlowCast, UVPoxy cures to a high gloss water clear finish. However, UVPoxy is a much more reactive formulation than FlowCast. The reactivity is optimized to allow it to cure quickly when applied as a thin coating. UVPoxy is not meant for small castings and does not have optimized air release.
