The garage floor has only ever had foot traffic.


On recent job (car port& boat shed) I had the floor power floated and
they added hardener to surface& that shows no sign of breaking up,
and it
has vehicle traffic.

Is there anything I can spay, pour on surface to stop this ? or

I have to use self-levelling 2-part, or perhaps even 2-part floor paint.

Going over it with dilute PVA will do the job cheaply - I'd probably
try 1:3
PVA:Water on a bit and vary it so it penetrates rather than glooping
on the
top, then roller all over.

It will be shiney afterwards, but not dusty - I did the same to a bit of
subfloor slab that was annoying me(!).

If you are worried about PVA becoming tacky or going weird when it
gets wet,
use SBR instead - costs more but will give a very stable surface and
will be
water resistant - also good enough to put floor paint on later if the
mood
takes (wouldn't fancy that with PVA in a damp environment).

PVA or SBR are surface treatments, a silicate concrete hardener reacts
with the concrete & changes the surface.

True, but both prevent dusting
