When layering, General Finishes says to let oil-based products dry 72+ hours before a water-based topcoat and let water-based products dry 24+ hours before an oil-based coat. Above 75% humidity, water-based finishes can blush; GF suggests its Accelerator plus extra air movement. Never pair a water-based topcoat with linseed or Danish oil systems.

FAQ
Which topcoat for cabinets and tabletops?
General Finishes calls High Performance its best choice for high-use areas such as tabletops and kitchen cabinets. It brushes, rolls, or sprays and dries clear.
Will a water-based topcoat amber?
GF lists High Performance as water white in the can and non-ambering. Oil-based topcoats such as Arm-R-Seal and Gel Topcoat amber as they age.
Can I topcoat over oil stain?
Yes, once it is fully dry. General Finishes says let oil-based products dry 72+ hours before a water-based topcoat, and not to use water-based products with linseed or Danish oil.
Can I clear-coat white paint?
General Finishes warns against any clear topcoat over white or light paint because it can yellow. Use a white poly or a self-sealing paint instead.
Interior or exterior?
High Performance is interior only. For outdoor wood, look at GF Exterior 450, spar urethanes, or marine spar varnish.
