Can a clear coat of polyurethane be applied over furniture that has been painted with latex paint?

Never tried this...but if you do use waterbased poly, and make sure the latex is fully cured before applying....I would be afraid of the latex lifting...





if i was going to consider this.. i would paint a board, let it sit for 48 hours, put on the poly and see what happens....Can a clear coat of polyurethane be applied over furniture that has been painted with latex paint?
Anything can be coated with something else, the question is should I do this? In this instance, you'll only cause yourself heartache. Latex and poly coats are basically incompatible. Latex is a much softer and less durable, surface-only coating than polyurethane, which when used on new porous surfaces sinks in and bonds on a molecular level. If this furniture item is for display only it may serve. Covering a softer finish with a harder one will only work if abrasion is severely limited or non-existent. Good paint integrity is like a chain and the chain is only as strong as its weakest link. You may be able to strip the furniture and use a water based acrylic solid stain to obtain the look and toughness you desire. Hope this helps.

I painted my porch with latex and applied poly to it and it held up just fine, After some time though the poly yellowed the floor.
yes. use water based poly.
