– GLEAN Stone Restorer and Sealer, Black, Impregnating Sealant Restores the Colour of Faded Black Limestone, Slate, Marble and Concrete, 500 ml

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!

Tiles looked great when it was first applied, however it states it is water resistant but it isn't. It is coming off every time I wash the floor.

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

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.

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.

Great restorer I use it for old /used slate tiles, once sanded and cleaned just rub this on,slate looks brand new ready for engraving on again. Money saver as well. Decent price delivered on time

Waste of money. Spent all day covering my slate tiles. Left to dry for 2 days. Mopped the floor and it all came off. Spent over £50 to have my tiles rejuvenated for 2 days!

This does work, however I put it straight onto a tile and it didn’t work, so what I did is scrub another tile first with Stainless Steel Sponge Scourer, wiped it down then applied this product and it worked. I did 2-3 coats. So don’t downplay this product just make sure the tile is cleaned and scrubbed first

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:(
