How to Fix Brush Strokes After Applying Polycrylic?
Asked by CraftyCoyote96
I'm new to woodworking and just finished building a table. I stained it and applied a coat of Polycrylic, but it dried faster than I expected, leaving some brush strokes. Can I fix this by lightly sanding it down, or am I out of luck? Also, how long should I wait before applying a coat of polyurethane over the Polycrylic?
Answers
Yeah, a light sanding with some 320 grit should help smooth out those brush strokes. If you want to keep using Polycrylic, go ahead and apply another coat after sanding. Just a heads up, Polycrylic is really just a water-based polyurethane, so if you're thinking about switching to polyurethane as a topcoat, that's totally fine as well. The hardware guy might've mixed up the details, but you’re not alone in facing this issue!

Definitely sand it down lightly, and when you reapply, consider thinning the next coat a bit. That should help with the brush strokes action. Just remember, finishes are pretty forgiving—if things go wrong, just sand it back down and give it another shot!

You can absolutely sand it down and reapply! If you find the brush strokes are still there after the first coat, you might want to try making a "wipe-on poly" by mixing the Polycrylic with water (about 50/50). It’ll take more coats, but there'll be no brush strokes that way! And if you still have any nibs after your last coat, a quick buff with some brown paper bag works great.
