Working with epoxy resin on wood can give beautiful, long-lasting results, but there are several common mistakes that can lead to disappointing finishes or structural problems. Recognising and avoiding these errors can make your next project smoother and more successful.
Incorrect Mixing Ratios
Epoxy resin must be mixed in the exact ratio supplied by the manufacturer—usually by weight or volume. Getting this wrong can prevent the resin from curing properly or leave sticky, soft spots on the finished surface. Always follow the product instructions to the letter and mix the two components thoroughly for a consistent reaction.
- Use precise measuring tools for accuracy.
- Mix for the recommended time, scraping the sides and bottom of the container.
- Resist the urge to ‘eyeball’ quantities or rush the process.
Not Sealing Porous Wood
Many hardwoods and especially softwoods can be surprisingly absorbent. If not sealed, air and resin can soak into the grain, creating bubbles and uneven finishes. To avoid this, apply a thin seal coat before your main pour, using a product like EpoxyWood which is designed to deeply penetrate and reinforce wood surfaces.
Rushing the Curing Process
Epoxy needs time to cure—often several hours or even days, depending on thickness and temperature. Attempting to handle or sand the surface too soon can cause smudges, fingerprints, or surface defects. It’s essential to allow full curing as specified by the manufacturer to achieve a durable, glossy finish.
When This Matters
Getting the process right is especially important for visible, high-use items like tables or worktops, where surface flaws or loss of strength undermine your hard work.
