Floor sanding with Angle grinder???

[raafbeard]

Possible? Or waste of time??

 

Being a bit tight to hire a floor sander...

 

Any sanding disc recommendations? Or should I stick to a belt sander/planer?

 

Have all of the above and would rather not hire a machine if I don't have too

No, an angle grinder will wreck the floor, too many nails for a planer. Belt sander would be ok but slow.

My preferred options for bringing a floor back to life are either carefully lifting, denailing and through the thicknesser, or using a floor sander.

You could do it but sanding across the grain will never look great and a risk of leaving deep scores in the wood. It would make a helava lot of dust as no way to extract with an angle grinder. I have sanded several floors back with a Ryobi 4" belt sander. You could probably buy one for the hire price of dedicated floor sanding machine and at least it is useful for the future.

Thanks for the advice mate.

 

Guess I'll get a floor sander, its not too expensive don't know if I trust myself to lift all the boards without breaking them and getting them back as they are meant to be..they are fixed quite well at the moment.

Iv just done my whole stair case with an angle grinder, with a flap disc- did a brilliant job and much quicker then the belt sander. If you wanted a really fine finish you may need to just rub it down with sandpaper or a light duty sander, but I think the angle grinder did fine.

I had quite a bit of paint on the stair two strips either side which the belt sander wouldn't do as it would clog up the sheets, so angle grinder was better for this as it is more aggressive.

As said, a huge amount of dust is created, but the trick I found with the grinder/flap disc was just be light handed with it using circular motions as if polishing a table.

Angle grinder.. used for grinding stuff, drill, used for putting holes in stuff, sander, used for sanding stuff. 

 

What kind of condition are the floorboards in to need sanding? and what kind of condition is the upside down face of them in? For ease if they are all lifted, can't you put them in upside down? Suitable attachments could cost as much as a cheap sander or sending them off to a carpenter to sand down
