Customer Reviews

First time I've used this sealer. Very impressive. Easy to work with and provides a good durable finish.

By Asim Hamid From Manchester

Excellent coverage

By Jane Lea

The block paving sealer was a lot cheaper than the rest on the market we were made up with it and still plenty left to do it again.

By Maureen Slater-murray

Excellent product with service to match.

By Deryck White

Easy to apply , hopefully no more oil marks. Underestimated amount to buy had to re-order but 2nd coat applied without any hitches. Natural Matt finish although in certain sunlight angles of view looks a bit shiny. But not enough to look bad. Good product will buy again


Excellent sealer. Follow the instructions and you will have a smart, new and weed free drive. Excellent customer service.

By Martin Holman

By Keith Bradshaw From Nottingham

Seems to be an excellent product, will be interesting to compare with the sovent-based sealer over time.

By Suzan Maric

New drive, new product, well new to us. Goes a long way, solvent free so no fumes when applying.25 lts plenty for our 50 or so sq metres. only drawback some places showing white on bricks after rain but dries out o.k all in all will use it next time we have to seal. Looking forward to seeing long time results, at moment rain running off and doing what it says on container.

By Mark Garside

Easy to apply, prompt delivery, happy so far, but too soon to determine long term performance.

By Paul Carruthers

I last used this sealant four years ago & have never refreshed it or washed the driveway down. In all honesty, I also economised a bit on sealer since the driveway is quite a big area & I should ideally have used 6 drums but just managed with four, so this year the driveway was looking a bit grubby & moss appearing in joints. I spent a few days raking out all the poor joints , applied moss killer and resanding. I also modified a little watering can and went over all the fresh joints with sealer to make sure there was enough to soak right in. Next day I did the whole of the driveway again : three drums were more than adequate since the blocks and joints were not very porous any more and because the driveway is slightly uneven I found brushing it on with a soft window-cleaning brush worked a treat rather than using the squeegee. It's all dried now, the finish is superb, rain just beads and runs off and the sanded joints are set hard. No smell, no mess, easy to apply, a superb product.

By John Scott From East Renfrewshire.

I purchased two drums of the Eco-friendly Smartseal block drive sealant. It was easy to use and the instructions, supported by an online video, were easy to follow. Ajob well done, I think.

By Tony Watson From Farnham

We always use the Solvent Free Block Paving Sealer (Eco Friendly) on our block paving. Easy to use, no smell and a fantastic finish.

By David Leopold From Ultimate Cleaning Solutions - Gloucestershire

So far it seems to be good, but as I told you on the phone my drive is not level and the Sealer ran down very quick in the joints. I had to order another two as I ran out very quickly. I would rate it 3. It may get better when finished.

By MICHAEL MURPHY From 211, Chells Way. Stevenage. SG2 0LX

the product was very easy to use,customer was delighted with end result
