Black Diamond Stoneworks Color Enhancer Sealer for All-Natural Stone and Pavers. Marble, Travertine, Limestone, Granite, Slate, Concrete, Grout, Brick, Block. (trial)

This amazing little product took my tiles, and I just installed on my backsplash in my kitchen from looking like a very chalky pale color to bringing out its natural array of Earth tones and took the chalkiness away. I only had a very small area to do so. I just brought bought the small sample size It worked fantastically, and it was exactly the amount that I needed. In the photo, the small piece of tile in the front is a extra piece i had left over that has not been sealed.You can see that its color is a lot paler than the color of the tile around it. The directions were easy to read and basically I painted the sealer on I did two coats.And the little bottle that I bought was perfect for covering the thirteen square feet that I had. I have just completed the backsplash, so I cannot say long term.How things will go?But for the time being, everything looks amazing.And I am very happy I believe this product needs to be reapplied occasionally.So I will end up buying the larger one in the future, but for the time being.This was what I needed, and it was perfect.Great value great product!

I bought the trail size as I have a few extra pieces of slate sitting around to test it on BEFORE I use it on my faded, old, blue/black slate patio and sidewalk. I did not want the “ wet look” as I did not want it to be slippery so, I bought the color enhancer one. Tried 1 coat on my test piece, let it sit for approx 10 or so min and wiped off with dry cloth. I WAS,AND STILL AM, AMAZED! It’s been about 2 weeks and yes, it has rained here about 3 times. Color was definitely enhanced as it now looks almost black. It does have a slight sheen and when I rub my foot over it with slippers and then flip flops on it does not seem slippery. It will take a long time for me to clean my slate and apply this but I feel sure it will be worth it. I still can decide though if I want to keep the color my slate is now ( a light blue/ black from fading over 40 years) or for it to be a much darker color. I am leaning toward using this product. Can’t do it at the moment as it is now in the upper 90’s here and it’s too hot to start on it. Another review said “ use it up to 80 degrees. I would say BUY IT!!

The product is a color enhancer only. I tested it on a cleft granite thin veneer stone. It does darken the stone and make the color variation pop. It provides no sealing qualities. After applying multiple coats and puddling the material on the stone to let the stone soak it in on my test pieces, the stone would not repel water. After the multiple enhancer applications, the color did not change but the water was still absorbed by the granite. The cost and time of this product and applying a sealer on top, didn't make sense.

Wanted to bring out tones in 2x4 tile travertine backsplash slightly, but got no perceptible color enhancement even with two coats. It did darken the grout slightly which was fine, and did seal the travertine tiles nicely. But I was a little disappointed. Maybe works better on more porous stone, but travertine may be too dense for it.

Color Enhancer Sealer worked wonders for my outdoor bricks. The hardest part, however, was prepping the bricks by cleaning them with vinegar and water and scrubbing with at steel brush. I prepped the bricks three times, three consecutive days because they had stubborn water marks (efflorescence) from years. Lots of elbow grease! Finally, I applied the enhancer with a sponge brush and with only one application, the bricks came back alive bright red. I only used between 1/4 to 1/3 of this small bottle. See pictures with results.
