Polyurethane is a very useful product with multiple uses. Curing times vary according to paint type and atmospheric conditions but a safe average is about a week. Last time i used rust oleum water based matte polyurethane. A polyurethane finish or varnish is a durable coating that protects a wooden surface which means you can t paint directly over it or your paint won t adhere to it.

However oil based polyurethane tends to yellow as it ages whereas water based varieties stay transparent. It s durable flexible and resilient. It was fine but i wasn t impressed enough with it to use it again. Applying polyurethane over a painted surface will give it an impeccably smooth finish.

You can manufacture it to be hard like wood spongy like upholstery. You can apply polyurethane over any type of paint as long as it s clean and has been properly prepared.

Preparation and application procedure if you re coating fresh paint allow the paint to cure first. Start by cleaning the surface and filling in any cracks or imperfections.
