Ensure Accurate Measurement and Mixing for Best Results

Getting accurate measurement and mixing is the foundation for any successful resin shower tray project. Careful preparation helps you achieve a smooth, even, and strong finish, reducing the risk of curing issues or permanent flaws. Here’s how to do it right.

Choosing the Right Resin System

Pick your resin based on the thickness of your planned shower tray. For layers up to 2cm, a multipurpose clear epoxy like “Trasparente” provides clarity and durability. If you require a thicker build, opt for a deep casting formulation such as EpoxyTable 5-Five (up to 5cm per pour), or for the deepest requirements, Epoxytable 10-Ten (up to 10cm). Selecting a resin that matches your project’s depth helps ensure even curing and minimal risk of overheating.

How to Measure and Mix Resin Properly

Always refer to your resin manufacturer’s recommended mix ratio, typically given by weight or volume. Use precise digital scales or graduated containers, as even small errors can affect curing and clarity. Pour the resin and hardener into a clean mixing container, then stir slowly for at least 3-5 minutes, scraping the sides and base regularly to avoid unmixed spots. For deep casts, prepare only as much as you can pour within the working time to avoid waste.

Never estimate ratios by eye—accuracy is essential

When This Matters Most

Precision matters most when making large or thick shower trays, where incorrect measurement can lead to surface imperfections, soft spots, or incomplete curing. This is especially important for functional surfaces exposed to water or soap, as proper mixing ensures durability and a flawless finish.
