Why is my Polycrylic breaking?
It’s called “alligatoring” and can happen when you put a hard finish (polycrilic) over a more flexible finish (latex paint). It can also happen when too much additive is used to help speed drying. So, if you added a drying agent (like Japan Drier) that could be the problem.
How durable is Polycrylic?
Polycrylic is basically an acrylic finish with a little polyurethane resin added. Like almost any other film finish you can use, there are no really “durability” concerns with the product, especially on a turning. But IMHO, turnings are often better served by oil finishes simply because of what they add to the wood.
Do you sand the last coat of Polycrylic?
Should Polycrylic™ be sanded between coats? Yes. A light sanding (#220 sandpaper) will remove any fine particles of dust which settle on the finish while it is still wet. Light sanding also helps abrade the surface, improving intercoat adhesion.
Can Minwax Polycrylic be used over paint?

How do you keep bubbles out of Polycrylic?
Avoid bubbles by flowing the Polycrylic from the brush.

Any bubbles that exist a minute or two after application will need to be cleared away before the Polycrylic dries.
Can you rub out a Polycrylic finish?
