Also, why am I getting bubbles in my polyurethane?The concept behind thinning the first coat is to fill some of the unseen or unfelt pores in the sanded wood. If polyurethane is thinned, it will seep into the undetected pores much easier than unthinned poly. If the wood has not been sufficiently sanded, it could show up as air bubbles.Likewise, how do you apply polyurethane without brush marks? A light coating of finish after sanding disguises the area. Sand down the brush marks lightly with the fine-grit sandpaper. Brush the sanded area off with a soft cloth to remove all traces of dirt and grit from the sanding. Apply the polyurethane finish lightly to the brush, making sure to wipe off any extra. Likewise, will polyurethane bubbles go away? In those instances where they still occur, allow them to hopefully dissipate on their own. Any remaining imperfections in the finish can be removed with mineral spirits for a period of up to 20 to 30 minutes after drying. Gently wipe the bubbles away and, if necessary, reapply the polyurethane finish to the area.How do you fix bubbled varnish? How to Remove Bubbles From Polyurethane Finish Scuff-sand the bubbles with 120-grit or finer sandpaper, depending on what you’re finishing. You would use coarser paper to scuff a floor than you would a tabletop. Wipe away the sanding dust with a damp cloth. Apply a fresh coat of finish, moving the applicator slowly to avoid turbulence and more bubbles. Tip.
