[Bobupndown]

Any recommendations for coating concrete floor ,100ish sq meters of garage floor. Very dusty naturally, looking cost effective solution.

if u want cheap and tough without color sbr bonding agent .one coat watered down and put on with a sweeping brush will seal it. you can coat over with concrete paint if u want

Polyurethane floor paint, follow the instructions

+1 on sbr. Cheap as chips from SF/TS.

Never ever use pva though. If pva gets water on it it'll get wet / slimy again. Even worse if you use pva under tiles, if water gets under the tiles the pva can "re wet" and the tiles lift!

watered down 50 percent will give you 2 gallons and go one hell of a way depends on how porous the concrete is

That's different...and a LOT more expensive than sbr.

Sbr is good stuff. I noted on the instructions for my bathroom tanking kit it said you could use it if you run out of the specific primer that comes with the kit.

that long ago cant remember the cost but i think maybe about £15 5l tub, it was black tubs though. Used it a few years ago for plastering aswell, but thats a dry area, either way if i cant find the 10l i have SBR isnt dear.

What sort of mix or ratio of water would be best, 1:1, 2:1,? I'd say a 5 litre container even mixed at 1:1 giving 10 litres would cover my whole area?

I recently drowned a porous screed with SBR , literally tipped out the bucket and swept it about and until it had all gone in. Works a treat.

Put floor paint in my garage, in retrospect I should've used something like SBR, or "water glass" (sodium silicate) instead. There was also some poly based sealer which soaked into the concrete that would've worked. At any rate I think such a solution is better than the thin barrier based one.

Here you go, see the bit about dustproofing:

UPDATE: A couple of months ago bought this product for dustproofing my new garage floor. I put three coats on, with drying time in between as per instructions.
All I have to say is that in my opinion, " It is worthless. "
