How do you cover the corner (inside & outside corners) "mistakes" in baseboards that are already installed?

Question

Baseboard corners don't line up. There are gaps in some. There are uneven matches in others.

Answer 1

Buy elmer's wood putty. It's water clean up and finally comes in a resealable tube. You can add, fill whatever you need to do to make it look better. Your repairs will be as strong as the orginal wood. Then sand and add until you get it right, prime it and paint it. Elmer's wood putty has interior and exterior ratings and it is excellent and cheap and easy to handle. You'll love what you will be able to do with it.

Answer 2

there are corner pieces that wrap around a 90 degree angle corner and come in various styles, you cut the baseboards off square and just put them up tight against the corner pieces that you install first. saves having to miter cut the baseboards. big-box hardware should have them, if not try a cabinet shop

Answer 3

I've used chalking and used a putty knife to smooth it out and then paint over it. DAP makes a new type of spackling called "Fast'N Final" that's real easy to work with. To get a really smooth finish on it all you have to do is damped the putty knife. Great for drywall.

Answer 4

Try stuffing in wood filler and sanding to a sharp edge. No one is going to crawl around on the floor inspecting them anyway (except maybe your brother-in-law) so filler and paint will hide those sins.

Answer 6
