Preventing resin leaks at your table edges is crucial for a smooth, hassle-free epoxy pour. Proper sealing contributes to clean results and saves time and materials.
Why Edge Sealing Matters
Epoxy resin is a fluid material and will seep through any gaps or joins in your formwork. If table edges are not properly sealed, leaks can occur, resulting in wasted resin, sticky workspaces, and compromised table edges.
- Ensures a crisp finish and accurate table shape
- Saves resin by preventing loss through leaks
- Reduces cleanup after your casting project
Effective Methods and Materials for Sealing
A popular and reliable approach is to use a silicone rubber paste on formwork joints and edges. This barrier blocks any escape routes for liquid epoxy, providing a thorough seal. The River-Table Complete Kit includes a specialist silicone sealant along with detailed instructions, making edge sealing simple—even for beginners.
- Apply silicone rubber paste to all internal formwork joins and corners
- For additional peace of mind, use a release film on the base for easier removal after curing
- Check your seals before pouring by running a small amount of water along the joints—dry any moisture before you start your resin work
When Edge Sealing Is Especially Important
Edge sealing is essential for deeper pours or when working with thin liquid resins such as EpoxyTable 5-Five. Thicker, larger projects place more pressure on formwork joins, increasing the risk of leaks without proper preparation.
Why formwork sealing is crucial
Overlooking formwork sealing is one of the most common causes of resin leaks when casting epoxy tables. Leaky forms waste costly resin, spoil symmetry, and can lead to uneven or incomplete edges. Investing the time to seal all joints thoroughly helps you achieve a professional result and keeps your workspace much tidier.
Specialised kits such as the River-Table set offer all the essentials you need for reliable sealing—including silicone suitable for use even on complex table shapes. Always inspect your formwork before pouring to avoid preventable problems later in the casting process.
