SmartSealNatural Stone Sealer - 'Wet Look' Finish for Sandstone, Limestone & Slate - Professional Grade, Easy To Apply Patio Sealer (3 x 5L)

Good product, easy to apply,used a short pile roller,tried spray gave it up,to many pools.LEAVE the first coat to soak in 45. 50 mins .I put on 4 coats,just the job,great finish

You get a lovely shiny floor but you have to re-apply a week later, I used it on slate floor in the kitchen which was really dull. It's now shiny and looks better, only real drawback is at 29.95 for a litre it's expensive.

Great product - used it for crafts to seal some engraved pebbles. It did the job perfectly 🙌

Goes on easily. Dries quickly. Leaves a good finish. I always use two coats.

Ultimately very disappointed with this product.I did a lot of research and tested the product beforehand with a sample bottle. It was applied in accordance with the instructions.Although it was of course very easy to use (apply with a cloth and leave to dry) it has only recently come to light that this product has failed. A few weeks after applying the sealer to flamed granite pavers I noticed what at first looked like a milky residue (similar to diluted PVA) on the pavers had appeared after a period of heavy rain. It looks like the rain has somehow got through the sealer in some areas and caused it to 'bubble'. It can now be peeled off. In summary, doesn't seem to have 'sealed' Please see pictures.

Excellent product, easy to apply. Really brings out the natural stone colour. All sealed ready for the next part of the project.

The surface must be clean . It works good

Used this on our riven sandstone patio. I applied this with a garden sprayer and got rid of pools of sealer with a paintbrush. Two coats and it looks great. The colours are brighter with a gentle sheen. Expensive but better than sealers I've used before.
