Before-and-after images help visualise the transformation possible with careful cleaning and a new resin coat. Real-world projects reveal how faded or stained sinks regain their original vibrancy and shine. For inspiration, explore customer success stories and gallery images using the recommended resin and colourants.

Step 1: Deep Clean and Prepare the Sink

Remove all soap, limescale, and grease from the sink to ensure the new coating or colour adheres properly. Use a non-abrasive cleaner and a soft sponge to avoid scratching. Rinse thoroughly and let the sink dry completely before proceeding. If the sink is heavily stained, repeat the cleaning process as needed for a spotless base.

Mask areas you wish to protect, like the tap or worktop edges. Protect surrounding surfaces from drips or splashes with tape and plastic sheeting if possible. This stage prevents contaminants from interfering with adhesion during restoration.

Step 2: Sand the Surface to Remove Residue and Prepare for Restoration

For areas with minimal colour loss, a gentle buffing with fine-grit sandpaper (600–1200 grit) can remove surface wear, light scratches, and residues. Always sand in circular motions with very light pressure. Thoroughly wipe away all dust with a damp microfiber cloth after sanding. Let the surface dry before proceeding.

If the finish is badly damaged or you are repairing a coloured resin section, prepare to apply an epoxy-based restoration coat in the next step.

Step 3: Mix and Apply the New Coloured Resin

To restore or renew the sink’s colour, mix a fresh batch of clear epoxy resin, such as Art Pro – Clear Epoxy Resin for Artists and Surface Coating, following the manufacturer’s ratio and instructions. For sinks requiring a colour refresh or complete recolouring, add several drops of Colourfun – Liquid Epoxy Resin Colourant to the resin, blending until you reach the desired shade. Stir slowly and thoroughly for an even, bubble-free mixture.

Pour or brush the resin evenly onto the prepared sink surface. Work in thin, even coats to prevent streaking. Avoid pooling and drips by spreading with a soft brush or roller. If treating a small area only, feather the new resin into the old surface for a seamless blend.

Step 4: Allow to Cure and Finish the Restoration

Epoxy resin must cure fully to provide maximum strength, gloss, and colour vibrancy. Always use gloves, eye protection, and ensure ventilation during the curing process. Keep the area dust-free and undisturbed for at least 24 hours (or the time stated by your chosen resin’s instructions).

Once cured, gently polish the surface with a clean, soft cloth to enhance shine. Remove all masking and inspect the colour finish. If necessary, repeat the application for greater coverage or intensity.

Allow full curing before using the sink again. Exposing the fresh surface to water, heat, or cleaners before the epoxy has set could compromise long-term results.

Tips and Troubleshooting for Sink Colour Restoration

Colour matching can be challenging—always test your colourant blend on a spare surface first. Too much pigment can affect resin strength; add colourants gradually and follow mixing recommendations. Take care to avoid air bubbles during mixing and application, as these can create patchy colour and a rough finish.

For high-wear areas or marble-effect finishes, a specialised kit like the Stone Effect Collection – Marble Epoxy Resin Countertop Kit provides comprehensive pigments and tools for a durable, designer look. Address stubborn or persistent stains with several thin coats rather than a thick single application for a smooth, lasting result.
