← Back to How to restore a resin shower tray?

Deep cracks in resin shower trays can seem daunting, but with the right approach and products, dependable repairs are very achievable. Restore your shower tray’s structure and appearance by following a proven repair method.

How to Repair Deep Cracks in Resin Shower Trays

For effective results, start by thoroughly cleaning and drying the area surrounding the crack. Any residual soap scum or moisture can compromise the strength of your repair. Next, use a suitable repair kit such as the Resin Fibreglass Repair Kit – Complete Polyester Resin and Hardener Set. This comprehensive set contains all essentials: polyester resin, hardener, fibreglass mat, gloves, brush, and container, simplifying the process. Mix the resin and hardener as directed, then apply with the fibreglass matting to bridge the crack, pressing down to ensure strong adhesion. Allow the repair to fully set before sanding smooth and, if needed, recoating for a seamless finish.

Choosing the Right Repair Kit

When restoring structural damage to resin shower trays, ensure your repair kit is compatible with rigid plastics or fibreglass. The recommended Resin Fibreglass Repair Kit forms a waterproof, impact-resistant bond that stands up to everyday bathroom use. Clear instructions make it suitable even for new DIYers, but always prioritise fully dry and clean surfaces for best possible adhesion.

When Professional Repair Matters

If the crack compromises the support structure or stretches across a critical load-bearing zone, or if you’re unsure about tackling the repair yourself, consider consulting a professional. Timely attention helps prevent water leaks and further tray deterioration, ensuring your bathroom stays safe and functional.
