How much sand paper

[BigCal]

I was just wondering if there is a "rule of thumb" when it comes to working out how much sand paper will do m2 of flooring...? I'll be hiring some sanding equipment probably next weekend to sand our floor but wouldn't know where to start with how much paper to get...

I know to buy more than I "think" because they will refund it, but at the moment I have no basis by which to "think" anything...

No one out there even prepared to give a rough amt? i just need a basis to work from... at the moment im thinking 14 of 40, 10 of 80 and about 8 of 120 for my floor which is about 40m2.. for the drum sander... and god knows what for the edger...

Cal, here are some pictures of a glue removal job I did last year. It has very similar glue to that gunk you've been blessed with.

For best results I find it much quicker and easier to edge the glue off rather than trying to sand it off with the drum sander.

The other tip is to spray the glue with Kerosene as you go, this softens the glue enabling it to come off relatively fast.

Thanks Dusty, its a job I'm really looking forward to... not...

Might go hire just a floor sander for the day... looks like you used about 20 discs if thats all of them on the bench... bloody hell i might be up for a few more i think i have more area...

[BigCal]

Oh BTW Dusty, was that 24 or 40 grit?

[Dusty]

The grit I would recommend is 24. Although, some of the discs in those photo's are 40 grit which I save from the drum sanding machine 'specially for jobs like this one.

As for how much sand paper you might require, well, that small section used up 20 or so discs and with what they cost from a hire place you'd be looking at $60 to $80 just to do a section the same size as in the photo's.

For that reason I strongly recommend that you consider having a floor guy come in and do it for you. It will work out cheaper and better overall.

Edit: Thanks to the moderator who put all those photo's onto the one page. Looks heaps neater.

Cheers dusty...

Every dollar I can save on this job is important at the moment so I will be doing it myself (surely by the time i pay someone for their materials and tim it must add up to being more expensive...) I i've quite been enjoying the work as its a big difference to sitting at a computer all day!! I'll see if the bloke that im getting the bona traffic product off also sells discs, might be able to swindle some a bit cheaper...

BTW, is that your work under your "some mighty fine floor sanding" link? some nice floors there for sure...

Hey Dusty, Did this job today, hired an edger from bunnies and bought some 24 grit from the Bona supplier for $1.20 a disc (much better than the $4+ from bunnies), my gunk can't have been as thick as what you dealt with in those pics, i did all of my area with 14 discs.. i had a couple of spots where it was thicker and it clogged the discs in no time... discusting crud it is... Came across heaps of staples under the black crud in a part of the kitchen that i had no idea were there so this dealt to a couple of discs as well...

5 hrs on the edger to get it done, rather sore now, especially after a day of pulling up tiles yesterday as well!!

Floor just needs some of the nails punched further and the staples removed (they're nice a polished after beeing sanded with 24 grit!!) and/or punched and then we're ready for the drum sanding which should be on friday with any luck... floor is still quite rough with other tile adhesive kind of concrete stuff so im going to start with 40 grit then 80 and finally 120...

cheers for the suggestion of the edger, altho it took 5 hrs any other method i was thinking of was going to take much longer!

Way to go, big fella.

Glad to help. Also glad it wasn't too hard a job.

I'm sure you will share the finished results with us all when your done.

Cheers.

P.S. A buck twenty for the discs is excellent, well done. You can see where the hire joints make their dough, with the amazing mark up on the bits and pieces we need to complete whatever jobs we tackle.

Definitely, the bunnies ones didnt seem as good quality as the others either... so you pay more and they probably don't last as long... Now i'm on a mission to find the abbrasives for the drum sander locally as well, the bona guy is a courier charge as well which didnt matter last time because he was sending me the finnish for the floor as well...

There'll be plenty of pics once its all finnished for sure!!
