What sort of sander should I go for, and how many belts/pads can I expect to go through in the course of onw normal size room.

The flooboards are brand new, unvarnished.

Cheers

Are you looking to hire one of the big b*gger sanders?

I know a few years ago we hired two sanders from a local company, one huge thing that nearly ripped my arms out and a smaller one to do the edges. In our deal we got a load of the sandpaper belts with them.

Sorry I am not being very helpful on technical stuff, but Lundy normally sees to that side of things

If they're brand new you should be able to get away with a high value grit (extra-fine).

If the boards are down already then get (hire) a floor sander. You should be able to return any unused papers.
Don't bother with an edge sander, just use a hand one.

You need two, a big belt sander (aka the devil's vacuum cleaner) and an edger. The hire place should be able to give you a good idea as to how many sheets, and they'll usually refund you for unused ones. Make sure you punch all the nails down before you start, otherwise you will go through a lot of sandpaper.

I've got a better idea - pay someone to do it. Not very helpful of me, I know, but after hiring one, ripping half a board out and getting angry at the guy in the hire shop it was money well spent. You'll be cursin' if you do it yourself.

Ta, got decorative nails so they should be out of the way.

Is it worthwhile buying a cheap sander? As they are new they just need a light going over I guess.

How much is it to hire one?

Hiring one is suprisingly cheep (<�100) IIRC.

I helped do my sister's a few years back and it was a piece of preverbial - even she could handle the machine.

If you're likly to use a hand-sander again then it wouldn't work out to be much more expensive.

About �30 or 40 for a weekend IIRC. Don't buy a cheap sander, the advantage of using a big hired one is that it's working on a largish area of floor at any time which makes it easier to get a really even finish.
I'd go for waxing the floors afterwards. It's more work than varnish, but if it gets scratched it's easy to touch-up.

I've hired a biggie.
The trick to not getting taken around by it is to press *down* on the handle, which reduces the pressure on the belt and hence the amount of 'traction' it gets...
Only real mistake was not taking really fanatical care with gap sealing, using the sander's collected dust + varnish/wax. You need to really carefully fill all the cracks, slightly proud of the boards. Then after it has 'set', sand it off level to finish.
Gaps in a suspended floor make for draughts...

BTW, Lidls happen to have a (smallish) belt sander today at �25. And cheap belts for it too.

I found them most efficient when dragged backwards rather than pushed forwards.

Hired edge sanders are very aggressive and have a tendency to score or leave circular patterns, so would advise using a random orbital to do the edges.

I wouldn't recommend a belt sander at all, particularly if the boards are a soft wood such as pine. It takes a lot of practice to get an even movement across the wood and it's very easy to gouge deeper hollows in it which are very obvious to the soles of your feet! Better by far to get an orbital sander (sort of like those floor polishers but with sandpaper); however, you might have to ring round a lot of places, because they're not easy to get hold of.

With new boards I'd buy a cheapish orbital sander, and not bother hiring a big mother of a belt sander at all, you just won't need it and stand as much chance of gouging out a big chunk as getting it right. Go over with medium grain, then fine. Invest the monies you've saved in some really good knee pads.

When you've got a good finish if you are varnishing hand sand lightly inbetween each coat. Its always the bits of hair that catch you out. And don't skimp on the varnish. Its the good stuff that'll last.

Its one of those things where you get a direct correlation betwen the amount of effort you put in and the finished result.

Really good tip about the gaps, though I don't suppose you've got many with new boards. Use PVA to mix with the wood dust to make filler for them if you do- its worth it in the end.

Best of luck. And think of us when you blow your nose after the first hour.

Cheers and thanks for the advice!

As they are brand new boards i don't have any gaps, they've been left in the house to equalise temp and cramped up really well. I know it won't last though.

bit late but if you did have gaps the first pass dust mixed to a paste with animal glue /size makes a cheap filler which sands a treat when dry and goes hard when varnished , pva and dust clogs the abrasive belts really quickly and costs a fortune in sanding . for a permanant finish use 2 part acid catalysed resin that stuff stinks but lasts extremly well once it sets it makes the surface very hard , water and stainproof , this is good with softwood as it is prone to puncture and water damage . hard wood should be treated either with the above or oiled . beware the sliding rug .
