Should I Sand Between Resin Coats on Wood?

← Back to How to coat wood with transparent resin?

Achieving a glossy, clear resin finish on wood is a rewarding process, but many crafters wonder whether sanding between coats is truly necessary. The answer is yes—sanding is an essential step for smooth, long-lasting results.

Why Sand Between Resin Coats?

Sanding between resin layers on wood surfaces helps the next coat bond securely, enhancing adhesion and preventing issues like peeling or poor levelling. It also removes surface imperfections—such as dust, minor bubbles, or unevenness—leaving you with a beautifully even final coat. Skipping this step can create unsightly lines or reduce the clarity of your transparent finish.

How to Sand Between Resin Layers

Allow the first resin coat to cure fully before sanding. Use a fine grit sandpaper—typically 320–600 grit—working gently over the surface until it loses its gloss and feels even. Wipe away all sanding residue with a clean cloth. This gives the next layer of resin a clean, keyed surface for maximum adhesion. After sanding, you can pour your next layer, such as with “Trasparente” clear epoxy resin, for a flawless finish.

When Does Sanding Matter Most?

Sanding is especially important for multi-layer resin projects—such as coating tabletops, art pieces, or restoring wooden surfaces. If you wait longer between coats or let resin fully cure, sanding becomes essential to avoid delamination. For projects needing a perfectly glassy result, don’t skip this step.
