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

The GLEAN Black Stone Restorer & Sealer is absolutely fantastic. It brought my faded black stone surfaces back to life, restoring the deep, rich color and giving them a beautiful finish. The application was straightforward, and the impregnating sealer has provided a durable, protective layer that repels water and stains. It’s been weeks now, and the stones still look as good as new. If you have faded black stone surfaces, this product is a must-try. It’s worth every penny for the incredible results it delivers. Highly recommended!

Restored the tiled floor colour very effectively.

We put this on our outside slate patio, it's left streaky marks where it was applied but worse, it's all black when you touch it or walk on it. We've tried to jet wash it off but it's still leaving marks and footprints. It's a nightmare, took ages to apply and now we have a patio we can't use. No idea how we are going to sort it out.

Used these in damaged sandstone slabs and the look wonderful but think we will need a gloss wet look ciber to stope the dusty footprints showing

Improved the colour of my slate tiles. Took a while to dry. Did 4 coats. Pleased with result. Although have noticed if water splashes on the ties and its wiped off, the black comes off too. Hope this is helpful.

I found the product to be absolutely fantastic providing that you take your time, well worth the money but make sure you clean the slate fully before applying

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

I used three coats of this on our limestone fireplace hearth stones. They've definitely made them look darker and hopefully also protected them. You need to be careful with the secondary Lid on this bottle. When I went to do the second coat, I couldn't get it out.. I tried squeezing it only for the bottle to burst.. spewing the black liquid all over my face, clothes, the dog, the bed and floor... It wasn't a good time...

Top!!! Super produit mon mur est éclatant comme au premier jour.

Non ci sono le istruzioni per come usarlo. Comunque ho fatto un po' di prove e non funziona

Creíamos que era otra cosa, realmente es un tinte negro que ni sella, ni da brillo. Lo único que hace es teñir y manchar muchísimo No hay instrucciones en español

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:(
