Nothing ruins the look of a glossy resin finish on wood like unwanted bubbles appearing during or after the pour. Taking a careful approach ensures a glassy, smooth coating every time.
Proper Wood Sealing Is Essential
Wood is naturally porous, so air trapped within can escape into wet resin. To help prevent this, always seal your wood before your main pour. Apply a thin layer of resin, such as EpoxyWood – Wood Restoration Epoxy Resin, and let it cure fully. This initial coat blocks air and gives your final layer a stable base.
Mix and Pour Resin with Care
Mix your resin and hardener slowly to minimise air entrapment—vigorous or rushed stirring introduces bubbles. When pouring onto your surface, do so in a steady, gradual flow. Pouring from a height or too quickly can trap more air and make bubbles harder to remove.
Eliminate Surface Bubbles After Pouring
Even with good preparation, some bubbles may still rise to the surface. Gently use a heat gun or torch to encourage any remaining bubbles to pop. Take care not to overheat the resin as this can cause surface flaws. Always work in a dust-free room to prevent debris settling while the resin cures.
When Bubble Prevention Matters Most
If you’re aiming for a crystal-clear, high-gloss finish on furniture, art pieces, or tabletops, eliminating bubbles is especially important. Visible imperfections are difficult to fix once the resin has cured.
