What Surfaces Can And Cannot Be Coated With Epoxy Resin?

When starting to work with epoxy resin, one may have many doubts. The most common of these is related to the number of surfaces that can be covered with thisresin (เร ซิ่น, which is the term in Thai). This can be used on virtually any surface. However, some preparations must be made on porous surfaces.

Below, we provideyou with a list of substrates that do not require prior preparation, porous surfaces that do, and some rare surfaces that cannot be epoxy coated.

Surfaces To Which It Is Directly Applied

  • MDF wood
  • Formica
  • Laminate
  • Tiles
  • Ceramics
  • Porcelain
  • Glass
  • Metal

Before applying epoxy, make sure the surface is clean and free of any impurities. If you are pouring a countertop, it is recommended to prepare the vertical edges by applying a coat of primer. Epoxy flows like honey and follows the rules of gravity; therefore, a thinner surface may be left over the edges. The primer coat ensures you get a consistent color throughout the piece.

Now that you know the surfaces on which it is easy to use epoxy, let’s see some others on which its use is slightly complicated. They are:

  • Porous surfaces
  • Wood (includes plywood, butcher block and live edge)
  • Concrete

Epoxy Coating

To coat epoxy that has been set for more than 12 hours, you will need to sand the surface so that the next coat can adhere. It is not necessary to be very much force; it must be done gently. This will ensure the correct coating with this resin.

Surfaces that cannot be epoxy coated

  • Copper
  • Silicone

The epoxy resin may not adhere to this short list of surfaces. It is good to keep this in mind when planning your project and be sure to carefully choose one of the detailed surfaces that epoxy can adhere to.
