Use a High-Quality Sealant for All Edge Joints

Edge joints are the most vulnerable parts of any resin shower tray. Using a reliable, high-quality sealant is crucial for a long-lasting, watertight finish and to prevent water damage or mould around your installation.

Why Quality Sealant Matters

Inferior sealants may fail to form a complete barrier, allowing moisture to seep beneath your tray and potentially damage supporting surfaces. A top-grade sealant is specifically formulated to provide strong adhesion to both resin and adjoining tiles or walls, creating a flexible waterproof seal that withstands daily use and temperature changes.

How to Choose and Apply Sealant

Compatibility: Select a sealant recommended for use with epoxy and resin surfaces as well as tiles or typical bathroom substrates.
Application: Make sure all surfaces are clean and fully dry before applying the sealant. Run a smooth bead along each joint, then shape it with a finishing tool or damp finger for full coverage.
Maintenance: Routinely check joints for any signs of wear or discolouration, reapplying fresh sealant as needed to maintain the waterproof barrier.

For a complete beginners’ approach, the “River-Table” Complete Kit provides you with silicone rubber paste suited for reliably sealing formwork or edge joints, plus step-by-step instructions for flawless results.

When This Matters Most

Sealing becomes particularly important in wet rooms, showers with irregular tray shapes, or where the substrate is prone to movement or settling. Investing in high-quality sealant at the outset reduces future issues and repair costs.
