Black Diamond StoneworksNEX-GEN Natural Stone Penetrating Sealer: Long-Lasting Protection Interior and Exterior ; Granite, Marble, Travertine, Limestone, Grout, Tile, Brick, Slate Floors (1-Gallon)

Easy to use and works

Surprised it did not have a spritzer with it. I know it didn't have one in the picture but II thought it was just a mistake. The product went on easy enough and time will tell how effective it is.

This is the best granite sealer I've ever used. Gets into the pores of the granite as well as little nicks and scratches in the granite so that, when you run your fingers over it, it feels perfectly smooth with no indication that there were ever any nicks.

I wanted a glossy finish and it turned out to be matte.

Product was easy to apply and left a wonderful luster on my granite countertops; just follow the directions. Glad the countertops have a level of protection that they didn't have before. No problems with order, delivery or condition of product when it arrived

Don't like it, I used it yesterday, end up with lots of water mark and matte finish after dry. I need to use another dry cloth to buff my floor, lots of extra work. My husband was saying what happen to the floor ?, you make it very dirty... since it was not as shinny as before application.

Best value for your money and does the job

This product has a very harsh chemical smell. So bad that I had to open all the windows in my house despite the cold weather. This left my granite counter tops feeling grainy and dusty. Did not like the product at all. I feel like I over paid for something that does not work. I’ll keep using method granite cleaner that I buy at Target for a fraction of the price.

Worked great on my 3000 grit polished concrete countertops.

I used this sealer for my DIY councrete countertop. It will slightly darken the surface from the untreated color. To give you an idea of the finished color, it’s about halfway between the untreated color and when it’s soaked with water.It has good water repellent properties however water sitting will be absorbed over time, you should clean spills ASAP, this product is not miracle, it only buys you time.I put 8 coats and let dry at least 2h between each. I used a small foam roller to apply and it worked quite well. Keep it wet for 5 minutes and wipe excess with dry cloth. Follow directions and don’t let product dry or sit on the surface.If using on concrete, you better finish it with beeswax for additional protection.

Didn’t appear to have done any thing after two coats.

My soap stone counter top was a beautiful marble colour. Now it’s dull and white splotches all over it. This crap ruined my soap stone.
