Concrete Sealer 5L

Bought this for a new build garage and it was so easy to use. It sealed the floor perfectly and was applied and dried in only a few hours in the summer. Would highly recommend

Excellent product. Although the product states indoor use, I used this to seal an outside slope. Previously the top layer of concrete on the slope was washing away in the rain leaving a powdery residue over the drive way. Once sealed the surface was stabilised and after several weeks of heavy rain the surface remains sealed and protected. This is so easy to use. I highly recommend this product as it solved my problem with one coat.

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.

Applied this to a brand new bare concrete slab in a garage. My main aim was to reduce dusting before laying rubber mats, rather than fully waterproofing the floor.I applied it with a standard roller and paint tray. It’s quite thin and watery, so be careful of splashing. A deeper tray would have helped. I only applied one coat.The 5L container covered roughly 30m² in my case as I used every drop.I applied it in November in an external garage, so drying time was longer than ideal in places, particularly where the slab was colder. It does dry clear, but it slightly darkened the concrete, which didnt much matter to me.Most importantly, it has significantly reduced surface dusting. That alone made it worthwhile for my use case.If you’re sealing a new slab and mainly want to stop concrete dust, one coat appears sufficient - but I suppose if it's high traffic or no matts I would have gone with 2.

Works very well, spreads easy. Good value

Works well dries fast -under an hour outside at 13deg CUsed a long pole & a paint roller on fresh concrete outside.No dust at all now

great stuff for sealing a large area of new concrete. easy to apply and totally effective.

The product has satisfactorily sealed a concrete garage floor. I used a roller and a paint tray. The roller is easily washed out with warm water and some dish soap. I was satisfied after 2 coats that the concrete was properly sealed. Impossible to judge long term durability at this stage. Coverage pretty good.A decent product, did the job.
