How Should I Prepare Gadget Surfaces for Epoxy?

Getting the best results from epoxy resin on your gadgets starts with proper surface preparation. By taking a few simple steps, you can maximise adhesive performance and ensure every bond is strong and durable.

The Essentials: Clean and Dry

Before reaching for your epoxy, remove all dirt, grease, and dust from the gadget’s surface. Use a gentle degreaser or isopropyl alcohol on a lint-free cloth. Make sure to let surfaces dry thoroughly—any dampness can weaken the resin’s hold.

Improving Adhesion: Abrasion and Fitting

Slightly roughening smooth plastics, metals, or glass gives the epoxy more texture to grip. Lightly sand shiny areas with fine-grit paper, then wipe away any residue. For best results, ensure the pieces fit together snugly before applying the resin for an even, gap-free bond.
