Choosing the Right Repair Product for Your Tray
Consider the size and depth of the chip when selecting your repair product. Use a fibreglass-reinforced putty for larger gaps, a rapid-setting epoxy for quick fixes, or a full resin and fibreglass kit for areas that require structural reinforcement and waterproofing.
Step 1: Clean and Prepare the Damaged Area
Thorough cleaning ensures product adhesion. Begin by removing all residual water, soap, and debris from the chipped area of the resin shower tray. Wipe with isopropyl alcohol or a suitable cleaning agent to degrease the surface. Ensure the area is completely dry before proceeding.
Careful surface preparation is vital. Sand the edges of the chip gently with fine-grit sandpaper to remove any loose material and to roughen the repair zone. This enhances adhesion for the repair compound and prevents further delamination.
Step 2: Mix and Apply the Chosen Repair Product
Based on the size and depth of the chip, choose your repair approach:
For structural reinforcement or larger chips, the Resin Fibreglass Repair Kit – Complete Polyester Resin and Hardener Set offers a robust waterproof solution. Mix resin and hardener as directed, then trim a piece of fibreglass mat to fit if necessary. Use the supplied brush and gloves to apply the blend over the chipped area, layered as appropriate, and allow to cure as specified.
For mid-sized, deep chips or holes, CROP 2K Fiberglass Putty – 750 ml + Hardener is ideal. Add the hardener to the putty following the pack instructions, then use a plastic spatula to press the product firmly into the chip. Level it slightly proud of the tray surface—this will be sanded flush after curing.
For small and shallow chips requiring a quick, less visible repair, select either “FixExpress” – Two-Component Epoxy Glue 500g or “Klebfix” – Two-Component Fast Epoxy Glue 2K, 25g Syringe. Mix equal parts, apply precisely using the applicator or syringe, smoothing to level as much as possible with a spatula. These solutions cure rapidly—allow only the recommended set time before proceeding.
Apply repair product precisely to the chip for best results. Take care to avoid contaminating the surrounding intact finish.
Step 3: Sand, Level, and Finish the Repair
Once the repair product has cured fully according to the instructions, gently sand the repaired area with fine-grit sandpaper until it is flush with the tray’s surface. Progress gradually to avoid over-sanding into original finishes. If needed, apply a touch-up coat and re-sand.
Clean away all dust and residue before considering repainting or sealing if your repair method requires it. For aesthetic blending, you may tint the epoxy solutions during mixing prior to application, so the patch matches your tray colour.
Allow full curing before using the tray. This ensures maximum waterproofing and durability.
Tips, Common Mistakes, and Troubleshooting
Patience and detail pay off in shower tray repairs. Avoid overfilling or underfilling the chip, as having too much or too little product requires extra sanding or a second round of filling. Protect the workspace with sheets or masking to contain dust and splashes. Be sure to ventilate the area and use PPE at all stages.
Typical mistakes include mixing incorrect ratios (especially for two-component products), using products unsuitable for constant water contact, or skipping the sanding step. Follow product instructions closely, and do not shortcut curing times if you want a long-lasting, waterproof finish.
Aftercare for Resin Shower Tray Repairs
Keep the shower tray dry and untouched for at least 24 hours after your repair to ensure a complete cure. Avoid aggressive cleaning agents and abrasive pads in the repaired area. Maintain the tray with gentle cleansers and check periodically for signs of further wear.
