The garage floor is giving off a lot of concrete dust, which can be seen by
exposed aggregate .. .and SWMBO is complaining that every time I walk out of
garage I leave a trail of white foot prints across brown pavior drive (they
do stand out)
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 would I
have to use self-levelling 2-part, or perhaps even 2-part floor paint.

I had a similar problem and went straight for the 2 part epoxy floor
paint, it stopped the problem and made sweeping the floor a darn sight
easier too. The only thing I would do differently if I was doing it
again would be to add sand to the mix to give more grip. If the floor
is wet it is somewhat slippery.

easy peasy. Use a concret hardener, works a treat

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.

Even that is overkill.

For simple dust prevention PVA will work, but its not fully waterproof.
Concrete paint - not two part - is perfectly adequate for low wear
areas. The epoxy is the dogs ******** industrial grade solution. Bloody
excellent but expensive.

True, but both prevent dusting

Look interesting! What sort of area would 5 litres cover?

Would it do anything to stabilise concrete which is crumbling and
forming craters due to the frost?

I have some TrueFix concrete PVA additaive, which was sprayed onto the
screed after laying to harden the surface .... I'll give that a go.
Any idea what the dilution is ?

There's a school of thought that says this is bad concrete work and
nothing can fix it...

Floor paint works, but it's expensive to get one (chlorinated rubber
or epoxy) that can stabilise concrete. The affordable stuff won't.

A better sealer for concrete is waterglass (sodium silicate). This is
cheap(ish), if only you can find it. It's a bit obscure these days.

Was the dry day/power float etc in the spec? If it was you should
have got 'em to remove and dispose of the incorrectly laid raft and
re-lay properly at their expense.

It was ... however they said 'no problem' screed will take care of it

The screed of course sorted out house, but not garage.

Been thinking of 'maybe' using a self leveling screed, but this may be
prohibitively expensive.

It's not too bad.

But you'll still need to stabilise the surfce or the bond will fail.
For that, I would soak it until it can take no more in 1:2 - 1:3 SBR:water,
which is exactly what I did with some friable screed I was about to top over
with compound. Worked too.

Don't know off hand, you would have to look at the can or ask the mfrs.

Would it do anything to stabilise concrete which is crumbling and

It reacts chemically with the surface of the concrete, so it would
prolly help.
