Working with resin on wood projects can produce stunning results, but various challenges may arise along the way. This guide covers typical issues faced and offers practical solutions to help you achieve a strong, attractive and durable finish.
Resin Not Adhering or Curing Properly
Poor adhesion or slow curing is often due to surface contamination, excess moisture, or incorrect mixing ratios. To avoid these problems, ensure your wooden surface is completely dry and thoroughly sanded before applying resin. Always measure and mix your resin and hardener as specified. For restorative projects, consider specialised products like EpoxyWood, which is formulated for deep wood penetration and sealing.
Bubble Formation and Surface Imperfections
Bubbles commonly appear during mixing or when resin seeps into porous wood. To minimise bubbles, use a low-viscosity resin and mix gently. Pre-sealing the wood with a thin resin layer can also help. For large casting projects, working in layers and allowing each to settle reduces trapped air, leading to a clearer, smoother finish.
Managing Thick and Large Casts
Thicker pours are at risk of overheating or incomplete curing. For deep projects like resin tables, select a resin suitable for casting at your required thickness—such as the “EpoxyTable 5-Five”, which is designed for up to 5cm. For even deeper work, cast in multiple layers and allow time between pours to avoid exothermic build-up and ensure an even result.
When This Matters
Understanding these common issues is especially important if you’re new to working with resin, tackling large projects, or restoring exterior wooden features. Careful preparation and the right product choices make all the difference in the quality and longevity of your work.
