SmartSealNatural Stone Sealer - Dry Finish – Impregnating, Durable, Clear Sealer for Sandstone, Limestone, Granite, Travertine & Slate - Easy to Apply SandStone Sealer Outdoor & Indoor Use (2 x 5L)

Bought a 100ml sample for the bowl of our birdbath after constantly havigg by to clean red algae off. Did 3 coats, easy to apply and still have some left. Now really easy to clean with a quick wipe.

Highly recomended

Bought to seal a fireplace granite floor, goes a long way easily covered 1 sq metre and so far has done the job of protecting the hearth and keeping it stain-free. Highly recommended

This product was good. Provided anti slip finish whilst not changing the natural appearance of the slate. Recommended.

Will need more thsn 3 to cover gravestone

I liked the delivery, it sealed my natural stone patio with the correct method of application, proof is water not soaking in the stone as it did before and you can now wash of dreaded bird droppings! Great stuff!

We had a new granite patio area laid and decided to seal the granite slabs after carefully keeping the area spick and span before 'leaves and debris' from a neighbours chestnut tree starts. The area was given two coats which the manufacturer recommends and within 2 weeks of sealing the area, the tree has dropped leaves and brown finger like debris which has left a brown stain after a heavy rain fall. We have kept the new patio cleared on a daily basis except when raining.This stone sealer is not cheap at £75 and is applied directly (ie. NO mixing or watering down) and frankly has been a complete waste of money...My advice is 'Avoid' and save your money.

Easy to apply and it really does go a long way. I didn't think I had enough for the job in hand but I had enough for two coats with almost 50% still left. Great buy.
