How long does Gorilla Epoxy take to cure on Oak?

Gorilla Epoxy takes 24 hours to fully cure on Oak at 70°F and 50% RH. Temperature and humidity significantly affect this — use the calculator on this page for an adjusted estimate at your actual conditions.

How do I prepare Oak before applying Gorilla Epoxy?

Sand to 120-grit — no finer, as over-sanding glazes the surface and reduces absorption. Wipe with a clean, dry cloth to remove dust. Do not use solvents before PVA or aliphatic glues.

Safety Warnings

Amine blush risk: At high humidity this epoxy may form a waxy surface film. The calculator will flag this if your conditions trigger it.
