Bostik Concrete Sealer 5L is rated 4.9 out of 5 by 19.
Rated 5 out of 5 by from Great Product, Easy to Apply Bought this to seal a garage floor to a new build house, over 3 years old, as the floor was dusty. Previously have used a resin product that was messy to apply and took ages to dry. This item was superb. Literally pours like milk and can then be rolled onto surface. It took 30 minutes to vacuum the floor and less than 20 minutes to paint the area of 3m wide x 7m long. I will leave it self finish but could readily be painted over with floor paint if desired.

Rated 5 out of 5 by from Great concrete floor sealer. Easy to brush and roller apply. It does go white during application so easy to see where you gave been. Dries clear. Only just had enough to cover my floor so square meterage stayed on tub is tight if you are applying first coat to untreated concrete. Very good product though and would recommend if you can get it!!

Rated 5 out of 5 by from Expensive but Worth it! Great Product for sealing my newly laid workshop concrete floor. Used a long handled roller to apply and it went on and spread like water although its a milky colour. Great coverage rate, only used approx 1.25 Lt of the 5 Lt tub to cover approx 12 sq mtr. Painted over the next day with concrete floor paint with great results.

Rated 5 out of 5 by from No more dust Brushed and then vacuumed my very dusty garage floor before rolling concrete sealer on. Very slight darkening in colour but the dust has gone away like magic. Appears to put a very thin rubber membrane over the floor. Dried in about 30 minutes (Summer application).

Rated 4 out of 5 by from Seems to be a quality product Goes on nice and easy and coverage is excellent. I used a roller and paintbrush to apply it to concrete flooring in a 6m X 6m double garage and one bottle did over half the area (and it wasn't applied sparingly!). Dries quickly and leaves a slight sheen that makes it easy to spot any bare patches for touch up later. Strangely, despite the floor being quite rough in places, a medium pile roller did a better job than the long pile I used for the second half, which left a few bare patches (not sure why this would be). Easily had enough left to reapply, so we'll see what happens. Poured some water on after a day just to check and it beaded off nicely, so seems to do the job. Also, doesn't seem to have an unpleasant or overpowering odour like a solvent based sealant would. Not sure why anyone has had trouble cleaning up afterwards as washing up liquid and warm water seen to clean everything off easily.
