How to Avoid Excess Sanding Pressure on Resin Shower Trays

← Back to How to restore a resin shower tray?

Restoring a resin shower tray requires care, particularly during sanding. Using excessive pressure can easily damage the surface, leading to unevenness or further wear. To achieve the best finish, a careful approach is essential.

Why Gentle Sanding Matters

Applying too much pressure while sanding a resin shower tray risks cutting through the protective layer or creating visible scratches. Resin trays often have a thin, glossy coating; over-aggressive sanding can wear this away and result in dull or patchy spots. Keeping sanding gentle ensures the surface stays smooth and preserves its original finish.

Best Tools and Techniques

Opt for fine grit abrasives and apply even, light strokes—let the abrasive do the work rather than pressing forcefully. A sanding block or hand pad can help maintain a level surface. When moving on to polishing, consider a suitable product like Epoxy Polish for returning shine and clarity, using a microfibre cloth or polishing sponge for the final touches.

When Extra Care Is Needed

Pay special attention around repaired areas or edges. If you’ve used a product such as the Resin Fibreglass Repair Kit, ensure the repair has fully cured before any sanding begins, and always use minimal pressure to blend the finish without risking new scratches or gouges.
