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!

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.

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

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.

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...

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!

As it’s water based, it’s very thin, and I’m sure might absorb into freshly quarried stone, but on mine, it’s simply ran off the stone. Where I did manage to get it to rest, it evaporated and made no difference to the tone of the stone. Just naff really… The photo shows which stones I coated, with some wet patches still visible but these even disappear when dried.

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.

​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:(
