## Customer Reviews

### ⭐⭐⭐⭐⭐ Highly recommend
*by  on Reviewed in the United Kingdom 25 December 2025*

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

### ⭐⭐⭐⭐⭐ Perfect Product
*by  on Reviewed in the United Kingdom 26 October 2025*

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.

### ⭐⭐⭐⭐ Sealing garage floor
*by  on Reviewed in the United Kingdom 24 April 2025*

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.
