Easy solution.
Worked remarkably well. Don't be too tight. Pour it straight from the container as instructed and spread with a mediium pile roller or a brush. Soon goes clear and dries hard over 24 hrs. Does what is says on the bottle.

Sealing garage floor
Just started to use product. Garage floor new and very powdery cement laid down. Swept up as much cement dust as possible and applied the Bostic product. It was easy to apply and dried quickly. I was impressed by the low coverage rate.After 1 st coat will probably apply a second in mainware areas.

Excellent garage floor sealer.
I used this to seal my new garage concrete floor. It’s about 25sq/m and I only used about half of this 5L tub, despite adding it quite liberally. I used a rolling brush with a long handle and it was really quick. The solution is milky and drys clear.My garage doesn’t have a door on it yet so it dried really quickly.I’m going to now paint the floor with Ronsenal Garage Floor Paint, but you could easily leave it like this. Great product and highly recommended.

Simple solution to reduce concrete dust
Like...simple roller application using kit I had already from my decorating box. Drys quick and you can see where you have bin. Leaves the original concrete a shade or two darker but otherwise no obvious difference in colour. It works, no sanding since I put it down. Dislike...went through a lot of it and had to get two 5Ltr tubs for a 6m x 7m floor area as the 'crete just seemed to suck it up.

Decent job but not great coverage
Covered a 17 sq.m floor in one coat which is all I really needed but, that was it. Not enough for touch up.

Worked perfectly on my garage floor
My garage was endlessly filled with dust so I gave this a go. Absolutely perfect. Easy to apply (be sure to use a paint roller that's designed for thicker paint or gloss) and dried quickly. Scrub the floor with disinfectant first and let it dry overnight, and remember not to apply 2 coats, as once it's dry it's done

Easily covered a 30m2 garage concrete floor
Sealed a 30m2 garage easily with just one tub. I bought two thinking I would need both but didn’t so sent the second back (sorry). Did the job well and would recommend it.
