Sanding particle board where it has buckled?

Q imported from our old site, Face Lift Floors: This is my problem. I have particle board throughout the house. The only area that I have a problem is where I installed self advise vinyl 12″ tile. The edges of the particle board have buckled up where they join to each other in some places.

I want to install hardwood laminated plank flooring. I am not going to remove the particle board. Is it possible to sand particle board where it is buckled with a belt sander?

A: I am not a big fan of particle board. Yes, you can sand particle board with a belt sander along the joints to flatten curled edges. It may take some time with a belt sander.

You may want to consider renting a floor edger for an hour. This is a much more powerful “grinder”. I use such a floor edger in refinishing hardwood floors and learning the technique and proper operation does not happen in a few hours, a day, or even several weeks. But you are only grinding plywood. No special experience needed. Also, get a few rough discs, say 20 or 24 grit.

Make sure you countersink any screws or spike heads first.
