How should I clean my sink before applying epoxy resin?

Proper cleaning is essential before you attempt any sink repair with epoxy resin. The right preparation ensures maximum bond strength and a smooth, lasting repair—here’s how to get started.

Why Cleanliness Makes a Difference

Epoxy resin needs a clean, grease-free surface to adhere effectively. Residues from soap, limescale, oils, or old cleaning products can prevent the resin from properly bonding, leading to weak repairs and potential rework. Going the extra mile with preparation leads to better results and fewer surprises down the line.

When This Matters Most

Thorough cleaning is especially important when repairing cracks or chips in ceramic or stone composite sinks, or where a product such as Magelstick Epoxy Mastic will be used. Well-prepared surfaces help ensure the epoxy bonds tightly and cures uniformly, which is vital for water resistance and a seamless finish.
