By Barrie Sharrock

Easy to use sealer with no smell. Used on new pavioursand the slight colour change was an improvement. Job not yet finished on quite a large area and I'm not sure if I have ordered quite enough.

By Gurdip Sidhu

This sealer is fantastic my neighbour asked me to order for him as well. I will advise others to use this one.

By Elizabeth Brahim

I was pleased with the very speedy delivery. We spread the block paving sealer from a watering can and used the spreader. It's quick and easy but we needed more sealer than expected as it absorbed quickly. We're very pleased with the result and confident it'll protect the blocks so definitely worth the money.

Product FAQs

Q: Hi If spraying the eco sealer what face mask would you recommend

Brent Evans

A: It is always worth wearing safety wear, it is never advisable to enhale chemicals if it can be avoided. Hope that helps.

Response from George

Q: how long does the sealant last after applying?


A: For optimum protection, we recommend a top up coat of sealer everyt 3-5 years.

Response from George

Q: Hi. How many litres would I need for a 25m2 block pathing driveway ?


A: For a 1st coat on 25m2, you would require minimum, 16.6L on a 1st coat, and 6.25L on a 2nd coat. 1 x 25L would suffice for an area of your size for 2 coats with the Solvent Free Block Paving Sealer.
