Why Use Silicone Rubber and Release Film in Resin Table Formwork?

The Role of Silicone Rubber in Formwork

Silicone rubber acts as a reliable sealant to close any gaps or join lines in your formwork. When constructing moulds for resin pours, especially for tables, using a specialised silicone paste prevents leaks and resin seepage, helping to deliver crisp, professional edges. This is particularly valuable if your formwork is made from multiple parts or needs to accommodate irregular shapes.

Why Use a Special Release Film?

A release film is applied directly over the base and inner sides of your mould. Its non-stick, adhesive nature allows you to demould your finished table without damaging surfaces or leaving sticky residues on your resin. This is essential for maintaining the clarity and smoothness of large, poured resin surfaces and is an invaluable step for minimising finishing work.

Practical Steps for Beginners

• Seal all joints in your formwork with a silicone rubber paste before pouring resin.
• Carefully line the inside of your mould with release film, smoothing out bubbles for best results.
• Refer to detailed instructions like those included in the River-Table Complete Kit to follow a step-by-step approach.

Using both aids helps minimise mess and frustration, especially if it’s your first resin project.
