Silicone Rubber for Reliable Sealing of Your Formwork

← Back to Buy Patio Resin Kits Online with Fast UK Delivery

Creating resin tables or patio features requires a well-sealed form to ensure crisp edges and prevent leaks during casting. Silicone rubber is a trusted choice for sealing your formwork, helping you achieve professional, mess-free results.

Why Use Silicone Rubber for Formwork Sealing?

Standard construction adhesives and sealants may not always withstand the weight or flow of resin, leading to costly leaks and lost materials. Silicone rubber offers a flexible, reliable barrier that adapts to minor imperfections in your form, preventing resin seepage at the joins or along the base. This is particularly helpful when working with complex shapes or reusable mould setups.

How to Apply Silicone Rubber Effectively

Before you pour resin, apply silicone rubber along all seams and corners of your formwork. Squeeze a steady bead, then use a gloved finger or spatula to smooth for a flush seal. Allow it to cure as directed before starting your pour. When you’re finished, silicone rubber usually peels away cleanly, making demoulding easier and leaving crisp edges.

Clean surfaces thoroughly before sealing
Apply an even bead – more in corners or where panels meet
Allow full cure for best protection against leaks

When Reliable Sealing Matters Most

Sealing with silicone rubber is crucial when working with deeper resin pours, intricate projects, or if you’re aiming to reuse your formwork multiple times. This not only protects your materials, but saves time on tidying up spills or reworking sticky leaks.
