While family and friends may give you helpful advice, reading the instructions on the can of stain leads to a beautiful final finish. Many brands advise buyers to plan on four to 12 hours of drying time between coats of stain and another 12 to 24 hours before applying the first coat of polyurethane.
Also question is, what type of brush to use with polyurethane?
Apply polyurethane using a bristle or foam brush about 2″ wide. Foam works well and eliminates the chore of cleaning, because the brushes are cheap and thus disposable. You can apply the first coat full strength or thinned up to half with paint thinner, making, in effect, a wiping varnish.
Do you have to sand in between coats of polyurethane?
Issue sanding between coats of polyurethane
- Apply a THIN coat of Minwax® Fast-Drying Polyurethane using a high-quality natural or foam brush.
- Let dry 4-6 hours. Then lightly sand entire surface with fine sandpaper (220 grit) to ensure an even finish and proper adhesion.
- Apply second coat. If third coat is desired, repeat step 5 before application.
What do you use to sand polyurethane?
After drying, sand first coat lightly with 220 paper on a sanding block. Wipe off polyurethane dust with a soft cloth, then wipe with a tack cloth, and begin applying second coat. I do not use sandpaper on the second coat. I use medium steel wool on the second coat, and fine steel wool on the third coat.
