Before staining and sealing pine with brush-on poly, what grit paper should be used to sand it?
I sand up thru the grits to 320 on bare wood before sealing with lacquer products. I also spend a lot of time looking at the surface in raking light to see if there are any scratches that have not been taken out with the sanding. Wetting the wood will raise the surface grain so you can sand that back, wiping with naphtha will show the color and any imperfections.
Cool, thank you.
I used to sand to 400, but over time decided there's no advantage to going finer than 220. You can use water to raise the grain, then sand again, or use the first coat of sealer to raise the grain, then sand it smooth again, either one works. Three coats minimum for poly.
