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.
Do I really need to sand between coats of Polycrylic?
Do You Have to Sand Between Coats of Polycrylic? Yes. Apply the Polycrylic and allow each coat to dry for about two hours.
How do I get a smooth finish with Polycrylic?
Sanding smooths it out and allows you to get a buttery soft finish. Paint doesn’t raise the grain of the wood, so I typically do not sand between coats of polycrylic over paint. However, if it feels rough to the touch after a coat of polycrylic, you can sand it with 400 grit sandpaper to make it smooth.
Can you skip sanding between coats of polyurethane?
Polyurethane dries slowly, so there are always dust nibs that should be sanded out before the next coat is applied. I never back the sandpaper with a flat block when sanding between coats to remove dust nibs, though it would be all right to do this if the surface is truly flat.
Do I need to sand between coats of finish?
When applying several coats of finish to a project it becomes necessary to sand between coats to not only remove any trash that has settled into the finish but also to promote good adhesion between the layers of finish. Here are some tips: Never sand any finish with less than 320 sandpaper.

How do you keep bubbles out of Polycrylic?

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?
With sufficient build it can be wet sanded and “rubbed out” to a piano finish if necessary. It takes successively soother grits of wet-or-dry silicone carbide sandpaper and water (up to 1500x-1800x). If less than that polished piano finish is desired, use a synthetic microfiber pad, like Scotch Brite.
How many coats of polyurethane is too many?
For ideal results, you should use about three or four coats. You will also have to wait quite some time between coats, as this polyurethane takes longer to dry. No matter how many coats of polyurethane you apply, it will always be quite a time-consuming process when using an oil-based finish.
Is it better to spray or brush polyurethane?
Every poly has its preferred applicator, typically a brush or cloth. Some polys also come in aerosol spray cans. Brush-on polys work best on flat surfaces where it’s important to build up a durable film. Aerosol sprays require good technique to avoid drips, and extra prep time to protect surfaces from overspray.
Is two coats of polyurethane enough?
Many people ask the question, “Is one coat of polyurethane enough?” More often than not, you will require multiple coats of polyurethane to protect your wooden surface sufficiently. Usually, you will need more coats of water-based polyurethane than you would with an oil-based product.

Apply a second coat of stain after the first has dried fully. This will usually produce a darker coloring, but it adds a step to the process and slows production. Leave a dampness of stain on the wood that dries to a darker coloring.
