Floor sander

[poynton phil]

I have a anhydrite floor to sand, what type of floor sander do i need, is it the same type as used on wooden floors. Thank you in advance, for any advice.

I use a slow speed rotary polisher/buffer 180rpm with 80 grit silicon carbide discs. It does the job great and does not great a lot of dust in the air.

Ya got there first Ramic

This is the best I have tried and I tried lots...Belt sanders ( hand held) 7" grinders with discs, drywall sander ( not bad but too much dust due to high speed) Floor sander ( belt driven, nearly blew it up)
This makes it so easy.

How much and where do you get the discs Neale !

 

[radim]

I hire mine from local carpet and flooring company, the same as Sir has. It is fast machine.

Cant rember how much but they are 17" annd I think they were from Abtec

Neale I have the same machine it came with 2 spare drive boards one of which I bolted carborundum stones to as on damp screeds the Silicon carbide discs clog too easily and over work the motor I will take a picture tomorrow but I recommend you try bolting the blocks on the drive board

gary u got these pics? sounds interesting...

I havent had one clog up as yet Gary but you never know.The reason I didnt want to bolt anythhing to the drive board is that I dont want to damage it or even throw it off balance. I use both brushes for cleaning purposes. If i had another spare drive board and the stones then maybe I would try it...the again I havent had a Anhydrite screed for months....most of the builders I work for have gone back to sand and cement.

If they clog it tends to mean the screed is too damp which means it's not ready to tile anyway...

But sanding also aids in the drying 🙂 , well if a laitence is present .
