Step 1: Clean and Inspect the Resin Shower

Start by thoroughly cleaning your shower to remove soap scum, limescale, and residues that can interfere with repairs or adhesion. Use a gentle, non-abrasive sponge or microfibre cloth to avoid scratching. Pay close attention to corners, drains, and textured areas where grime may build up. Rinse thoroughly and allow everything to dry before moving on to inspection.

Once clean, check closely for chips, cracks, dull patches, or deep scratches. Note any areas that require surface-level attention and those needing more robust repair. Cleanliness is critical before starting any restoration.

The Strong Technical Degreaser for Resin Projects – 100% Natural Formula can be applied to efficiently remove grease and residue without harming the resin, ensuring an optimal surface for subsequent steps.

Step 2: Sand and Smooth Surface Imperfections

For light scratches or dull spots, start by wet-sanding the affected areas. Use a fine grit (start with 400 grit, moving to 800 and up to 1200) and sand with gentle, circular motions. Rinse and wipe clean frequently to monitor progress and avoid over-sanding.

For stubborn marks or more pronounced dullness, use incrementally finer grits to gradually restore smoothness. Be cautious—overzealous sanding can thin the surface or leave uneven patches. Remove all dust and residue before proceeding.

Step 3: Repair Cracks or Chips

If you discover cracks, chips, or structural damage, these must be securely repaired before finishing. Prepare the damaged area by lightly sanding and taping around it for a clean working margin. Following the product instructions, mix and apply repair resin to fill and seal the imperfection, ensuring complete coverage and a slightly raised surface for later smoothing.

Where reinforcement is required, such as deeper cracks or holes, a fibreglass mat can be cut to size for extra strength. Allow the repair to fully cure based on the specified product time before sanding flush with the surrounding area. Patience is essential for a professional finish.

The Resin Fibreglass Repair Kit – Complete Polyester Resin and Hardener Set is ideal for these structural repairs and comes with everything you need for a seamless restoration.

Step 4: Apply a Clear Epoxy Resin Top Coat

Once the surface is repaired and completely dry, mask off the shower area to avoid spills. Mix the clear epoxy resin thoroughly, according to the provided ratio, in a clean container. Pour or brush the resin evenly over the surface in a thin layer, and use a gloved hand or a spatula to distribute it smoothly.

Work in a dust-free environment and allow ample time to cure according to the product guidelines. Avoid touching or using the shower until the resin is fully cured, which typically takes 12–24 hours.

For a durable, high-gloss and protective finish, “Art Pro” – Clear Epoxy Resin for Artists and Surface Coating is specifically formulated for decorative and protective layers on resin surfaces.

Step 5: Polish to Restore Shine

After curing, if the surface appears slightly cloudy or has minor imperfections, polishing will enhance gloss and remove light blemishes. Use a polishing cream suitable for epoxy resin, working it gently into the surface with a soft pad or microfibre cloth. For best results, use circular motions and minimal pressure.

Continue buffing until you achieve a mirror-like shine. Remove any remaining residue with a clean, dry cloth. Buff gently to avoid scratching the resin. For a flawless, professional finish, the “Epoxy Polish” – Epoxy Resin Polishing System is recommended for use on newly restored showers.

Tips and Troubleshooting for Resin Shower Restoration

• Always wear gloves and work in a ventilated area. Epoxy resins and hardeners can be sensitive to skin and odours.
• Test your cleaning and sanding methods on a small patch first if unsure.
• Do not rush cure times; premature use can damage fresh resin layers.
• If bubbles appear in the resin, pass a heat gun or hairdryer briefly above the surface to encourage them to rise and pop.
• Keep the shower dry and free of dust during the entire cure and polishing process.

Expert Advice for a Lasting Finish

Clean early, let cure fully and take your time at each phase for durable, beautiful results. Attention to every step ensures your resin shower stays glossy and watertight for years to come.
