Should I Sand Between Resin Layers on Cabinets?

For anyone making or refinishing resin cabinets, achieving a smooth and reliable result depends on how each resin layer adheres. A common question is whether sanding is necessary between coats.

Why Sanding Between Resin Layers is Important

Light sanding after a resin layer has fully cured helps the next pour bond more securely. Smooth, glossy cured surfaces can prevent the new layer from adhering properly, potentially leading to uneven finishes or even delamination. Sanding introduces a gentle texture, providing a key for the following resin layer to latch on to. This simple step is especially important for cabinet projects where durability and visual appeal matter.

How to Sand Resin Layers Effectively

Allow the applied resin to cure completely before sanding. Use fine-grit sandpaper (such as 320–400 grit) to gently scuff the entire surface, taking care not to gouge the resin. Brush away or vacuum any sanding dust to avoid trapping particles between layers. Afterwards, proceed with the next coat, ensuring the surface is dry and clean. For large or deep resin coatings, choosing the right resin is essential—products like EpoxyTable 5-Five are designed for smooth, thick pours and can be layered efficiently with light sanding.

When This Matters Most

When aiming for a high-gloss, professional look on visible cabinet surfaces.
If your project uses multiple resin pours to build up thickness or embed objects.
On larger pieces where adhesion and surface quality are crucial for long-term durability.
