When doing hardwood floor and sanding out 3/4 OSB Tongue and grove plywood will a belt sander work? I dont currently own one and Im putting hardwood floor down. I mean I should own a belt sander but I dont.

Im just worried about it cutting the paper on the nails/screws in the floor.

Or should I rent something more powerful?

If you are talking about prepping subfloors prior to install, I use an edger. A 7" grinder with a 36 grit sanding disc works pretty good too, but kicks out a helluva lot of dust....not that cool in occupied but fine for new construction.

For prepping subfloor especially that which has a bunch of old 1/4" staples in it I have found that the best tool is a Hilti DCG500 and Dustless cup shroud attachment. It cuts down everything high and leaves the surface like it was sanded with 60 grit... the wear on the wheel is unique as it pulls more bonding material leaving more exposed diamond... not as bad as mortar residue (wears the cup fastest) but more than when running on concrete.




You can see that this pic was taken after being used on wood from the yellow orange color of the diamond blocks

got a grinder and used sanding grit wheels.

Worked great. Kicked outta lot of dust but it all blew off the walls with the compressor in 5mins. Thx hardwood floor looks great.

I hope you didn't install hardwood flooring on top of that particle board in the pic.

I use either my edger or a floor sander with a used 24 grit belt. The floor machine does a better job of containing the dust in an occupied home.
