Can Oil and Water Based Products Be Used Over Each Other?*

Yes! But you must follow ONE simple rule to ensure the best possible finish: the underlying finish must be absolutely dry.

When using a water-based product over an oil-based product, such as water-based High Performance Topcoat over oil-based Gel Stain, wait 72 hours before applying the water-based product.
When using an oil-based product over a water-based product, such as oil-based Arm-R-Seal Topcoat over Water Based Wood Stain, wait 24 hours before applying the oil-based product.

General Finishes Enduro-Var Urethane Topcoat can only be used over raw wood or General Finishes water-based wood stains or dye stains. Enduro-Var cannot be used with any oil-based product, sanding sealer or shellac.
