## Customer Reviews

### ⭐⭐⭐⭐⭐ Premium product
*by A***A on 7 November 2021*

The media could not be loaded. This has to be the best sealer on the market.a bit pricey but after 2 coats gave my driveway a beautiful wet and glossy look.no weeds so far for last 6 months

### ⭐⭐⭐⭐⭐ It does everything it claimes
*by J***Y on 21 September 2021*

Used on block paving turned out to be exactly as we imagined

### ⭐⭐⭐ Cannot really tell
*by S***E on 16 June 2023*

Sent for a sample tin (which was not cheap) and the tin I was sent was very small - could maybe cover one or two blocks. I was expecting to be able to cover a reasonable area to try since it is quite an expensive product but could not. When I asked to return the sample unopened I was told I had to pay the postage myself. So a good idea to try a sample but it hasn’t worked out. In the end I cut my losses and put it down to a bad example of customer experience with that company.
