Clean the Surface Thoroughly
Preparation is crucial for a flawless white finish. Clean the sink, worktop, or mould to remove all grease, dust, and old residues. If restoring an existing sink, lightly sand or degloss the old surface to increase adhesion. Remove all sanding dust thoroughly using a moist cloth and allow it to dry. Tape off any areas you don’t want coated, and ensure every surface is dry before beginning.
Mix Resin and White Pigment Evenly
Measure your epoxy resin and hardener precisely according to manufacturer’s instructions. Add the recommended dose of white pigment or dye, stirring slowly to avoid introducing air bubbles. Ensure the colour is completely even—no streaks or clumps—otherwise your final sink surface may appear patchy.
If you need a highly decorative finish reminiscent of white marble, consider using the “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit, which includes pre-measured pigments and essential additives for seamless colour blending and marbling effects.
Pour and Shape the Resin
For thicker sinks—especially those with a depth greater than 2cm—use a deep pour resin such as “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting or “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm for optimal clarity and depth in your white base. Pour slowly in stages if necessary to reduce heat build-up and prevent bubbles. For coated surfaces or inlays, spread the coloured resin evenly using a notched trowel or spreader. Monitor for air bubbles, popping them with a heat gun or torch as needed.
Sand and Finish for a Polished Look
Once the resin has fully cured (refer to the chosen product’s cure time—typically 24-72 hours), carefully de-mould and begin wet sanding to refine the surface. Start with 400-grit and progress up to 2000-grit for a glass-like sheen. Polish with fine compound or specialised polishing cloths for maximum shine. For final food-safe and UV-protected sealing, apply a clear coat with “EpoxyFood” – Certified Clear Food Contact Epoxy Resin for Coating if required, ensuring at least 7 days of full cure before putting your white resin sink into everyday use.
Tips, Common Mistakes, and Troubleshooting
Use ample ventilation and PPE when working with resin to ensure safety and the best finish. Avoid pigment clumps for a uniform white—stir slowly and scrape the sides of your mixing tub. Take your time with deep pour layers, as rushing can trap bubbles or cause yellowing due to excess heat. Always measure and mix carefully to avoid sticky surfaces, and do not use your sink before the resin has fully cured for maximum durability.
Expert Advice for Lasting White Sinks
Maintain the brilliance of your white resin sink by cleaning with non-abrasive cloths and gentle soap. Avoid aggressive scouring pads to keep the surface glossy. If stains or dullness appear over time, a light re-polishing with a fine compound can restore its pristine look. For heavy traffic or food-safe applications, the right topcoat makes all the difference.

Frequently Asked Questions
What is the best white pigment for resin sink projects?
Choose a resin-compatible, non-yellowing white pigment or paste. Kits like Stone Effect Collection include suitable pigments for strong opacity and stability.
Can I make an old sink white with resin?
Yes. Clean, sand, and coat the old sink with pigmented resin. Surface preparation is crucial for good adhesion and coverage.
How thick should a resin pour be for a sink?
Use deep pour resins for bowls 2–10cm thick. Pour in stages for thicker castings to prevent heat build-up and ensure clarity.
How do I achieve a marble look for a white resin sink?
Use marble-effect kits with appropriate white and grey pigments. Manipulate with spatulas or isopropyl alcohol to create veining effects.
Do I need food-safe resin for a sink?
For kitchen or direct food contact, finish with a certified food grade resin such as EpoxyFood, especially on rinsing or prepping surfaces.
Why does my resin sink look yellow?
Exposure to UV or incorrect mixing can cause yellowing. Always use resins with UV filters and avoid direct sunlight curing.
