Sand and seal my OSB sub-flooring?

bnewman's picture

I would like to sand and seal my OSB sub-flooring in my new home construction, instead of buying hardwood flooring. I would like to delay that expense for a couple of years. Can you comment on that idea?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

No real problem with that as a temporary fix. You will find that the first coat of poly will raise the edges of a few of the 'wafers' because the coating shrinks as it dries and pulls the edges up.

Leave the first coat to thoroughly harden before cutting back and continuing with the next 2 coats.

Seen a few in Artist Lofts in Venice California. Just so long there is no moisture underneath and the sheets are staggered across the joists.

Floor enamel would cover the printing better and faster.

seen osb & advantek sealed, especially at entry doors    check w their tech lines to see if they have recommendation   may tell you to avoid oilbase as it could attack glue     


presand high areas w belt sander (agressive belt if raised considerably) and set high nails      wouldn't sand the whole floor, just high or bad areas    hand operated belt sander is best, using a floor machine will cause damage to the equipment as you get down to nails

Thanks to everyone for the tips and tricks. I appreciate it!

First comment I ahve is don't use OSB in the first place. Use Advanteck!

Oooops? Already too late? Then you absolutely need to seal it.

Before the time of Advanteck, we would use up old leftover paint on plywood subfloors when it was likely to be exposed to the elements for awhile to help it out. Won't hurt you at all. My DW just reminded me the ply subfloor in the bedroom needs another coat or the final floor soon.

In my old house I put OSB down over the old asphalt tiles because I was told they may have asbestos and didn't want to take them up and find a way of disposing of them, etc. I masked and painted a sort of border around a field. Between the way the various chips took stain and the stain creeping under the masking tape, the end product looked like an oriental rug. Only problem was that I didn't sand enough (or put enough coats of poly on it) so it was kind of rough.
