GLEAN Black Stone Restorer & Sealer | BLACK | 1 Litre | Impregnating Patio Sealer Restores Colour Of Faded Black Limestone, Slate, Marble & Concrete | Interior & Exterior Sealant

Took 4 coats. Totally panicked after the first 2 coats as was so streaky and patchy. Bought wo more bottles and did 2 more coats. Looks great finally. I tried applying with a small roller, a sponge and a large roller. The large roller worked best but had to really concentrate around the grout. We have had heavy rain since and my worry about it streaking was put rest. I would recommend but be patient

This works so well. We had a Black limestone patio fitted years ago and over time it has become more grey than black. I have used all kinds of treatments to bring back the colour but nothing has really made a huge difference. I bought the small bottle to try it and the difference is amazing. It turns out that for my patio I actually need 2Litres but that is so worth it. I have applied by paintbrush to each slab and the difference is amazing. The photo shows the difference between the old colour and the slabs I have just completed. This was 1 coat - no second coat required so far.

Very disappointed with this product needed to give my charcoal block paving kerb edges 5 coats to get it looking half decent . Each coat goes on well and looked great nice and dark but few hours later looked faded again and the paving is only laid last July so one year old. . Just order another product black Magic it’s had great reviews for doing the same job. Fingers crossed it’s as good as they say and most cases needs only one coat .

Restored the tiled floor colour very effectively.

Amazing! I used this to restore a couple of gargoyle statues in my garden. They look better than new, I’m very happy. It was incredibly easy to use (brushed on a thin layer with a paintbrush) and it dried quickly too. Photos show before and after just one coat.

It did not cover my granite worktop properly and that which did take rubbed of when wiped to clean

Loved this product, it's a bit pricey but you do get awesome results. We put a water sealer on our new patio, because there is so much dust in the air on the new development, it soaked in as it was drying ugh...so had to strip it all off then as you see in the first photo, it was pretty light. One coat only so far, it's used practically all of the 1 litre bottle, and I will need to do a second coat for my liking, but am really impressed. I just rollered it on and just watch you go easy!

To cover an area where dish soap had taken the colour. I felt it never really did the job and if wipe several days later, the black comes off.

Produits récemment utilisé sur les galets à l'origine noirs de la douche mais très "fatigués". Deux couches effectuées renforcées par une couche de rénovateur pour carrelage (vernis). Produits aisé à appliquer ici à l'aide d'un pinceau et résultat très concluant. Maintenant à voir résistance dans le temps avant un nouveau traitement Attention petit bemol, toutes les informations d'utilisation sur le flacon uniquement en anglais.

​Ich bin sehr enttäuscht von diesem Produkt. Für Schiefer ist es absolut ungeeignet. Die Konsistenz erinnert eher an Wasserfarbe; sie zieht überhaupt nicht in den Stein ein, sondern bleibt lediglich auf der Oberfläche liegen. ​Das größte Problem: Selbst im trockenen Zustand lässt sich die Farbe mit einem einfachen Lappen wieder abwischen. Im Duschbereich ist das Produkt eine Katastrophe – beim Duschen löst sich die Farbe und man bekommt schwarze Füße. Für den Nassbereich oder Schiefer ist das Produkt definitiv nicht zu gebrauchen:(

Nicht so ganz wie vorgestellt, aber ansonsten bis jetzt, ohne das erste Mal gewischt zu haben, passabel.
