Can you use epoxy over stained wood?

Yes, though the effectiveness varies depending on the type of stain used.

Alcohol-based and water-based stains are ideal and dry fast. An epoxy coat can go over them in about 24 hours.

Note: This is meant to be general advice. Some niche products may be uniquely different from the average stain of these types and cause unforeseen issues.

Oil-based stains such as Minwax will take a very long time to fully dry. If an oil-based stain is used, you must apply a clear oil-based polyurethane to seal the surface before applying a seal coat of our UltraClear table top epoxy. If you pour epoxy directly onto the oil-based stain before it has dried completely, the epoxy may end up not bonding properly and could peel off months later.

Note: Even with two or three coats of oil-based polyurethane, you'll still need to apply a seal coat of epoxy; don't skip that step. The poly does not seal the wood adequately to prevent air bubbles from forming during the epoxy flood coat phase.
