Can you put epoxy over polyurethane?
Accordingly, can I put two part epoxy over polyurethane?
If your surface has an oil based stain or oil based paint, you must apply 2-3 coats of oil based polyurethane before doing the seal coat. The polyurethane will cover that and allow the epoxy to stick. This does not take the place of the epoxy seal coat as that is still necessary.
Also, can you pour on polyurethane? To seal the wood before top coating, thin your oil-based polyurethane to one part mineral spirits and two parts polyurethane (first, gently stir the contents in the can). Pour the products into a glass jar and gently stir the mixture with a flat stir stick. NOTE: Never shake a can of polyurethane!
One may also ask, does epoxy bond to polyurethane?
Epoxy and Polyurethane compounds are thermoset plastics. Epoxy and Polyurethane substrates bond well to each other as long as the surfaces are clean and slightly abraded.
Can you use glaze coat over polyurethane?
You can turn any clear finish into a glaze by adding pigment, or you can buy a pre-mixed glaze. Oil-based polyurethane and epoxy resin glazes work best on cured polyurethane. Apply with care.
