SmartSeal's Natural Stone Sealer - Wet Look Finish - Professional Grade, Easy To Apply - Durable Gloss Sealer for Sandstone, Limestone & Slate (2 x 5L)

Great product. I used it indoors on grey slate floor tiles. They always looked a bit dull except when they’d just been mopped. I put four coats on over the course of an afternoon and they have a lovely sheen to them now. Easy to apply. Ready for extra coats in about an hour. And no smell or mess. Not sure how durable it’ll be in a high foot traffic area, but fingers crossed.

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.

Good product and the bottle went far covered a stoney wall approx 20ft high x 15ft wide with some left over for touching up. Nice sheen not glossy as we only did 1 coat. But great has really highlighted the colours well

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.

After much research I tried this and it's perfect. Easy to sponge/roll on, dries quick. Keep adding coats for glossier finis. Btw it goes far.

It's definitely sealed the brickwork as you can tell the difference in texture however to say wet looks is totally misleading. I specifically wanted to bring the original colours back as they look after being wetted and this product only slightly brings up the colour. I'm disappointed at £30 per litre I was expecting it to be as described. Not returned as used most of it. Avoid

I have a 300mm sandstone ball in my garden and when it rains, the colours on it really pop and stand out, it looks beautiful. I thought this treatment would give it that look permanently, but it just looks ever so slightly darker. Thankfully I only purchased the sample size. Did 2 coats but only used half a bottle.

The surface must be clean . It works good
