See How a Professional Shower Tray Repair Is Achieved
Watch as the entire process, from surface prep to final resin finish, is demonstrated. Notice the importance of cleaning, careful material application, and patient finishing for a flawless result. Each stage is key for a fully waterproof and long-lasting repair.
Step 1: Clean and Prepare the Tray
Begin by thoroughly cleaning the entire surface of the shower tray with warm water and a mild detergent. Remove any soap scum, oils or contaminants as these will affect adhesion of the repair materials. Once rinsed and dried, degrease the area around the damaged section with acetone or isopropyl alcohol for an extra level of cleanliness. Use masking tape to define the repair area and protect the undamaged surface if necessary.
Cleanliness is key to successful bonding. Any residue could cause the repair to lift over time.
Step 2: Sand the Damaged Area
Sand the cracked or chipped area using P120 sandpaper to roughen the surface and feather the edges. This provides a firm base for your chosen repair medium. Remove any loose particles and dust with a microfibre cloth.
Ensure the area is dry and free of debris before proceeding.
Step 3: Fill and Repair Cracks or Holes
For cracks or deeper chips, select CROP 2K Fiberglass Putty – 750 ml + Hardener. Mix as per product instructions and use a spatula to generously fill the prepared area, pressing firmly to eliminate air bubbles. Shape the surface as closely as possible to the surrounding tray. Allow to cure fully—refer to manufacturer curing times.
For smaller chips or quick repairs, “FixExpress” – Two-Component Epoxy Glue 500g can be ideal. Its quick setting time and strong bond make it suitable for minor surface defects requiring rapid fixes.
Do not rush the curing or sanding stages. Curing properly ensures a solid, lasting repair.
Step 4: Sand and Smooth the Repaired Surface
Once the filler or adhesive is fully cured, sand the repair with P120 and then P400 sandpaper. Shape it back to the original tray contour. Use light, circular motions to feather the edges seamlessly into the surrounding area. Wipe off dust with a damp or microfibre cloth and inspect for imperfections. Repeat filling and sanding for any low spots or pinholes.
Step 5: Apply a Protective Finish
For a fully water-resistant, glossy finish, apply a thin coat of “Art Pro Deluxe” – Ultra-High Viscosity Epoxy Resin for Artists over the repaired section. Mix as directed, pour or brush on evenly, and allow it to self-level. Avoid disturbing the surface while it sets—follow minimum curing times for optimum results. This added layer protects against water ingress and replicates the high-gloss look of a new tray.
If masking tape was used, peel it away gently before the resin has fully cured for a crisp, clean edge.
Tips and Common Mistakes
- Always match the repair material to the severity of the damage: Deep cracks may need filled fibreglass putty, while minor chips respond well to rapid-set epoxy glue.
- Ensure each product has fully cured before moving to the next step—rushing can lead to soft, uneven patches.
- Sand gently; pressing too hard may cause low spots or mar the surrounding finish.
- Work in a ventilated area and always use gloves to avoid contact with resins or solvents.
- If the tray has a patterned or textured finish, use masking and fine brushes to replicate it during the final epoxy layer.
