Hi, I have a groundwood floor which has been polished with a polyurethane polish.

It has started to crack and peel in a few places. I`ve not done any polyurethane work before. so I`m debating whether to strip it and repolish using a resin polish like Oleo or  an emulsion polish. The floor is buffed regularly so either of these should hold up ok.

But the floor apart from the cracking/peeling bits is in really good condition, its a large school hall floor. So i`m after finding out if I can just repair the damaged parts with a polyurethane finish.

As far as i`m aware polyurethane is the hardest wearing out of the 3 options, are there any other benefits or anything I need to be aware of if i do decide to strip it.

Many Thanks

  I take it you mean Granwood flooring? There a composition of cement and sawdust blocks. Never had to strip one yet. I would try a neutral floor cleaner first (chemspec) with a blue pad. If that doesn't work then your'll need to strip it. Re-seal with chemspec floor sealer if you need to strip, otherwise if ok after cleaning seal with chemspec tight shine.

If it is the Granwax solvent based sealer you are trying to strip you will struggle. It needs to be sanded and by that not in the normal way of sanding.

If it has been over coated with floor polish then you may be in with a chance using the method Mark suggested.
