Hump in subfloor


Is it ok to use a wood floor edger to sand the hump out of a subfloor in order to avoid having to use floor leveling compound? The hump goes perpendicular to the floor joists in my kitchen and it is raised up about an 1/8", possibly a hair more. Just curious on how much is too much to sand out.

Hump in subfloor


Hi and welcome to the forum.

If it's SOLID hardwood flooring, I'd be comfortable doing it, but absolutely not if it's engineered/veneered/manufactured stuff.

If unsure what it is, lift out a register cover in that room and look at the edge of the flooring.

In my kitchen I sanded the 3/4 thik subfloor at a joint (speedbump) at least 1/8 then covered it with a good linoleum floor. I prepped the floor first by screwing down the subfloor joint to stop movement and squeaks. I am watching this thred because the next floor in this kitchen, possibly winter 2011/12, I might go tile/ceramic, and I am unsure if I compromised the subfloor strength.

Maybe someone with more experience can give us the run down on floor prep, in the meantime I will do some searching around.

Thanx in advance
Frank

Hump in subfloor


What is the material you want to sand? Is it in fact hardwood flooring, or something else?

What causes the hump?

What will you do next?

The more information you give the more accurate your responses will be.

Hump in subfloor


Are you asking me??

My subfloor is just your everyday 3/4 tongue and groove plywood. It has a hi spot either because of the joist right below this joint is a little high or the two other joists (one on each side of the joint) being a little low. I did see on a "Homes" show that they just sand the floor more or less level.

your opinion?

He is asking what the final floor covering will be. That would determine how to fix it.

You can sand the subfloor to make the hump go away.
