Black Limestone Sealer - Transforms, Recolors, And Protects Slate & Black Limestone Surfaces - Perfect Easy to Apply Slate Sealer - Highly Effective & Long-Lasting (3 x 5 Litre)

Follow the guidlines and it makes a great improvement to the limestone slabs. It really brings out the natural colour, easy to apply, I did it with a pain brush and it came out better than I expected.

Easy to use gives patio a lovely shine. But it is expensive.

Easy to apply, but very strong fumes , even though it was tried on my back door step first won't apply to the rest of my garden limestone slabs as it would make them to dark will wait and see how long it will take to fade as I would have preferred a bit lighter black stone.

I bought a sample tin to try out first of all which cost £7.99. I applied the sealant to a spare patio slap which had broken and based on the results I decided to purchase a 5 litre container at £69.95.My patio is about 32 square metres in size and the 5 litre tin applied one coat to the entire patio and steps with a tiny bit left over. I’ve ordered another 5 litre tin to do my path and to apply a second coat to the patio but only to areas where I think it could do with a touch up.I’m pleased and surprised with the results. My limestone slabs were starting to fade despite only being laid 12 months ago. I’ve attached before and after photos to show the results. I will explain them later.I applied the sealant with a 1 inch brush to paint the joints and a six inch roller to cover the stone surfaces. The job was spread over a couple of days because of our wonderful temperamental weather. The total duration to seal the patio took 4 hours overall. I had to return to a small area by the back door to apply sealant when everybody was out for the day. There is an odour with the sealant but when working out doors it’s fine and the smell does go away quickly once applied.So on to the photos. I’ve taken a few of the patio to show how it used to look and to give you an idea of the area. Then I’ve taken some photos to contrast between the old and new. A few of the photos were taken a day after I’d completed most of the coverage and we’d had heavy rain over night. You can see how the water pools and beads on the patio surface. One of the photos shows a close up of a small area by our back door which I had to do when nobody was home but you can see the difference between the old and new colour. I be taken a close up photo of this section to show the deep black colour once applied. I hope these photos and descriptions are helpful to form an opinion on how effective the product is.As I mentioned earlier I’ve ordered another 5 litre container to do my limestone path next and will post more photos before and after once I’ve been able to do the job.While at first I thought the product was expensive the fact I’ve ordered it again tells you I’m satisfied with and importantly very happy with the finish. More importantly my wife likes it and as the saying goes - happy wife, happy life.

Was initially concerned if it would work (as had treated paving with a sealer when laid 4 years ago and other comments saying it was like a paint). I cleaned patio twice with Sodium Hypochlorite from Amazon and pressure washed, let dry for 3 days and then applied. I used a 4" foam roller to cut in edges, however as it applied it so well i used it for the whole area, about 30sq m. First coat took 90 mins second coat 60 mins.Since applied it has rained on it it and the garden furniture both wooden and metal have not scratched it either...looks superb and still have half a tin left!... It does have a strong odour but if instructions are followed you will not be disappointed!!

Do my garden in two halves. Takes about 90 mins but lasts a year. Seals it very well. Good product

Good coverage, needed two coats to bring my limestone back, but looks good.

Took a while to get the coverage right. I found a paint roller and tray best in the end. Product goes a long way. Be sure to shake the tin well prior to starting. Looks fantastic when fresh, though I think will need an annual renewal. Only issue is that being a sealant (obviously) the slabs are incredibly slippery when it rains and/or freezes. Trainers are particularly bad and several family members have slipped over when approaching my house. I warn everyone! Shame, as I say, looks great!
