When building a resin-coated staircase, ensuring each step has clean lines and no unsightly drips is essential for a professional finish. This is where formwork comes into play, acting as a temporary mould for every stair tread and riser.
Why Formwork is Needed for Every Step
Formwork acts as a barrier, keeping liquid resin exactly where you want it and preventing it from spilling over the edges or seeping between steps. Without it, resin can leak out, run down the staircase, or form rounded corners instead of sharp, defined edges. Building formwork around each stair tread and riser also gives you the control needed to achieve the crisp lines and thickness that are characteristic of modern resin stairs.
Choosing and Setting Up Your Formwork
Opt for a non-stick formwork material, such as melamine board or suitably coated timber, which allows for easy removal once the resin cures. Ensure each piece is securely fastened and sealed at the joins—simple tape or silicone can help prevent unwanted leaks. The time you invest in patiently setting up formwork prevents costly messes and extra sanding later on. If you’re working with deep resin layers, a product like EpoxyTable 5-Five supports thicker applications without risk of deformation, provided your formwork is solid.
When This Matters Most
Formwork is especially important for projects involving multiple resin pours or steps that require a substantial edge profile. Whether your design is simple or incorporates striking, clear resin features, formwork ensures your hard work results in straight edges and a leak-free application.
