How to prevent drips

Drips form when resin runs over the edge of a piece and cures into a hardened trail down the side before you can catch it. It's a finishing and technique issue, not a mixing problem — the resin itself isn't at fault. This guide covers how to stop drips before they set, and what to do with the ones that get away from you.

Why drips happen

Resin needs to flow to self-level, which is part of what gives a piece its glassy finish — but that same flow is what carries resin over an edge if there's too much of it or nothing to stop it. Pour more than a surface can hold, work without an edge barrier, or tilt your workspace even slightly, and the excess runs downhill under its own weight and hangs there until it cures.

Preventing drips before you pour

• Tape the underside edge. Run a low-tack painter's tape (something like Frogtape works well) around the underside of your piece before pouring, following the edge closely. It won't stop resin from reaching the edge, but it catches the drip on the tape rather than on your work, so removal later is a peel rather than a repair.
• Pour what you need, not more. Measure the surface and mix close to the amount it actually requires. A controlled, shallow pour is far less likely to overrun the edge than a heavy one.
• Work the edge as you go. With gloved fingers or a brush, run along the edge while the resin is still workable to guide any resin that's crept toward the side back onto the surface, rather than letting it run down.
• Level your workspace. A perfectly level surface spreads resin evenly. Even a slight tilt pushes extra resin toward one side and makes a drip there far more likely.

Removing drips after curing

What to do next depends on whether you taped the edge.

If you taped the underside: wait for the resin to reach a hard cure before peeling the tape off. Pulling it too early, while the resin is still soft, risks smudging the edge or tugging at the artwork itself. Hard cure time depends on which product you used:

Product	Approx. hard cure
Arts & Crafts	24 hours
Table Top	36-48 hours
Deep Pour	48-72 hours

A little gentle heat — a hair dryer, or a heat gun kept moving and at a distance — can make the cured tape more pliable and easier to lift cleanly. Never apply direct heat to a Deep Pour piece; it's prone to cracking and yellowing under a heat gun or torch, so that technique is for thin coating layers only.

If a drip cured without tape underneath it: you'll need to remove it mechanically. Sand it down, starting with a coarser grit and working up to a finer one, or use a rotary tool for more control on an awkward edge or corner. Go slowly — it's easy to take off a little more resin if needed, much harder to put it back.
