Should You Sand Between Resin Layers for Best Results?

Sand Between Layers for Maximum Adhesion and Clarity

When working with resin tables, achieving a strong bond and a clear finish between layers is vital for both durability and appearance. Sanding between pours is a simple step that can make all the difference.

Why Sand Between Resin Layers?

Each cured resin layer forms a naturally smooth, glossy surface. While this might look appealing, it often prevents the next layer from adhering as securely as possible. By lightly sanding the surface, you create a gentle texture that promotes mechanical grip, helping the next layer lock firmly in place. This process also helps avoid any visible lines or separation marks, contributing to long-term clarity and strength.

How to Sand for Best Results

Choose the right grit: Use fine sandpaper, usually 500–1000 grit, to avoid scratching too deeply but still provide enough texture.
Keep it even: Sand gently and evenly across the surface. Aim to dull the gloss without removing too much material.
Clean thoroughly: Remove all dust with a clean, damp cloth or tack cloth before pouring the next layer. This prevents particles from becoming trapped in your resin.

If you’re new to resin work, consider a kit like the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table, which includes a polishing kit and clear guidance for multi-layer projects.

When This Matters Most

Sanding between layers becomes especially important for deep pours or when more than 24 hours pass between resin applications. It’s also crucial if you need a flawless, glass-like finish that stands up to daily use.
