Which surface treatment for dusty concrete floor?

[clangers_snout]

I'm about to lay some ceramic tiles on our kitchen floor but the concrete onto which I'm laying it is a bit dusty, i.e it produces dust if swept with a broom.

Is there a surface treatment which will stabilise it so that the tile cement will stick to it?

Yes.

Soak it in 1:1 diluted SBR - ideally as much as it will absorb in one session.

It will set it like a rock through quite a thickness from the surface due to the excellent penetrative powers of SBR.

Tile adhesive loves SBR and it is 100% water resistant (as in the SBR is stable and will not go mushy - it does give some water resiting properties to the substrate but it is not tanking).

IME tile cement will bind up any amount of dust when applied with a spreader. A 10% pva solution makes a good stabiliser to be on the safe side

Its no big deal - just slosh water on it before the cement Or use thinned PVA. I've done both. Both work
