After repairing a cracked resin shower tray, it’s vital to allow the repair area enough time to cure before using the shower again. Proper curing ensures the repair is durable, waterproof, and ready for daily use.
Typical Curing Times and What to Expect
Curing times can vary depending on the repair product you use. Always consult your product’s packaging for exact instructions. Most polyester resin and epoxy repair kits require at least several hours to harden fully, with some recommending that you leave the tray undisturbed overnight. As a general rule:
- Polyester resin and fibreglass repairs: typically 6 to 24 hours
- Epoxy glues or putties: can set in as little as 5 minutes, but full strength is usually reached after several hours
- Colder or more humid rooms may slow down curing
How to Ensure a Lasting Repair
To guarantee a reliable fix, always follow the instructions for your chosen product and avoid using the shower until the suggested curing period has passed. For example, with a Resin Fibreglass Repair Kit, overnight curing is usually safest, particularly if the environment is cool. For fast-setting epoxy options, allow some extra time beyond touch-dry for the repair to reach full strength before exposing it to water and normal foot traffic.
When Curing Time Matters Most
Being patient with curing is especially important in busy households or rental properties. Using the tray too soon can weaken the repair and lead to further leaks or cracks, so plan around the curing schedule to avoid inconvenience and costly rework.
