Garage base query

[OpenToSuggestions]

Recently I had a concrete garage put in, which I am happy with the job that has been done.
The concrete surface seems to be a bit powdery, as in rubbing it with hard my finger creates dust.
I sweep up the garage often, but the dust keeps coming back as it is coming from the surface.

I have read this thread:
https://forums.overclockers.co.uk/threads/garage-floor-seal-paint-cover-whats-best.18740667/
However my base seems to be quite soft.

A quick google suggests I need to apply a sealer or floor paint, such as this:

Alternatively I could put perforated rubber matting down.
The garage external dimensions are 22'3" long x 9'6" wide.

I'm sure Motors has sufficient knowledge to help a garage/workshop newbie make a cost effective decision .

tis worth putting a decent sealer down, mate of mine did this on his shed 30+ years ago and the floor is solid to this day (and we're no strangers to dragging heavy metal objects across the floor)

Unsealed concrete will always produce a dusty top layer, so get a sealer on it and it'll be good for many many years.
