Yellowing can affect the look of any resin shower tray over time, making it appear dull or aged. The good news is, restoration methods exist that can visibly improve or even resolve discoloration depending on its severity.
Understanding Yellowing and What Can Be Fixed
Minor yellowing is typically surface deep and often caused by exposure to light, cleaning chemicals, or build-up from soap and hard water. These types of imperfections usually respond well to polishing products formulated for resin surfaces. Polishing can lift away surface stains, restore gloss, and bring back the tray’s original brightness.
How to Improve a Yellowed Resin Shower Tray
The first step is to thoroughly clean the tray, removing all soap residues and minerals. Next, use a dedicated resin polishing system, such as the Epoxy Polish, with a rotary polisher or an appropriate pad. Work in small sections using circular motions to gradually buff out the yellowing and revive the shine. For those aiming for a transparent and durable finish, a high-quality clear epoxy like Trasparente Epoxy Resin can be applied as a ultra-thin topcoat after preparing the surface, providing fresh protection and a crystal-clear look.
When deeper yellowing requires more than polishing
If the discolouration goes beyond the surface or the core resin material is affected, polishing alone may not be sufficient. In these cases, lightly sanding the tray and recoating with a clear resin layer is recommended. This approach seals and conceals the yellowed area underneath while delivering a long-lasting, glossy result, although it involves a bit more preparation and care.
When this matters most
Restoring yellowed shower trays is most important when the tray forms a central part of your bathroom’s look or before attempting to sell or rent your home. Addressing surface yellowing early helps prevent further deterioration and keeps your bathroom looking fresh.
