Floor sanding accessories

Well, I'd take that with a pinch of salt ey.
I've come across all sorts all more so lately cement based screeds that need sanding, and if your sanding within the first couple of months they all sand pretty easily, the diamond can be over kill for them.

Take a look at Abtec Abrasives website, they stock things like silicon carbide screen meshes which are less aggressive than cup wheels but tend to be for larger machines at 225mm or 430mm.

We point people to them when they are trying to sand or polish some microtoppings that behave more like a levelling compound than a sand/cement screed.

The advantage of diamonds only kicks in when you're removing a lot of material or the floor is very dense/abrasive, or both.

I've always sanded them but am going to do a test next one I get. Primed, unprimed, sanded and primed, unsanded and umprimed. I'll fix with anhyfix as usual and post results.
If it was a screed company saying that then I'd take it with a lot of salt but can't imagine a company like knauf making a statement like that without it being factually correct. Big firms like that tend to err on the side of caution. Who knows?
Big risk as opposed to a relatively small amount of work though
