How Do I Avoid Marks or Drips on the Edges of Resin Projects?

Edge Preparation Before Pouring

To prevent resin from dripping or pooling along the edges, it’s best to mask the sides of your project using a good-quality tape. Apply tape flush along every edge, ensuring there are no gaps or overlaps. This acts as a barrier, minimising runs and helping control the flow of resin.

• Press tape down firmly for a tight seal.
• Choose low-tack tape for easy, residue-free removal.

Pouring Tips for a Smooth Result

Set your piece on a completely level surface—this is crucial for even resin distribution. Pour resin slowly and methodically, working towards the taped edges but not flooding them. Take care not to overfill, as this increases the risk of run-off.

Once the resin has partially cured to a firm but flexible stage (often reached after a few hours), gently peel away the tape. Doing this while the resin is still slightly pliable helps avoid sharp lines or sticky threads. If you’re aiming for a professional finish, resins such as Art Pro help, thanks to their controlled viscosity which resists sagging and drips.

When This Matters Most

Careful edge preparation is especially important for showpiece work, like trays, coasters, or serving boards, where neatness counts. For rounded edges or projects with intricate shapes, patience with taping and pouring pays off with a cleaner look and less need for sanding or touch-ups.
