Hi all
What is your set up for prepping these floors as far as sanding goes
I've always hired polishers with 60grit
But I've got a biggish floor to do that is going to be in stages
Is it better to be Looking at buying second hand
Is it a polisher with adapters to take the disks
Anyone know of company's they deal with that sell on there equipment
Thanks in advance

60 grit sanding pads wont be enough for sanding off laitance
Copper disc or diamond cups will do it but you may need some dust extraction depending on how dry the screed is
This is something I have been doing a lot more of and have invested in some good gear and have opened up another business for it

Have a look at a sander called Sand Glider. I saw it being used on a site I visited and seemed to be doing a very good job. It may be on You Tube and it is available through some tool hire shops.

simple STR floor sander with SPE ltd turbo disc seems to take care of most situation quickly and easily and most of all cost effectively.

Thanks for your replies
Is this disk a sanding disk or grinding type of set up
I managed with a 60 grit sanding disk on a small floor
Would this struggle with bigger area?

60 grit is usually sufficient for a loose friable laitance. This is a sand paper disk that goes onto an STR sander (the type that people of a certain age would have seen the school caretaker using to polish the hall floor). If the laitance has become hardened or baked on but remains flaky then a lower grit or more aggressive disk such as a copper disk is ok. The turbo disk is impregnated with diamond studs so is a cross between sanding and grinding. It seems to cut through most laitance easily whether on anhydrite or sand cement or cement based flowing screed. The only place I know of that sells these disks is SPE ltd. They have depots in Lincoln and Norwich that I know of but others that I might not know.

Ive bought an Errut prm twin disc floor grinder which uses 6 carborundum blocks and has a low dust emission I use this regularly as an extra to my tile work aswell does the job well !

60 grit is perfect if the timing is right. admittedly, if the screed has been left for months you'll struggle!

Your gonna need diamond grinding cups let’s not pretend sand paper is gonna do it!
