I was expecting to spend my whole weekend doing my master shower however it only took couple of hours. I plugged in my audiobook and time passed quickly. Prep/cleaning was tedious because I didn’t want to repeat the process. The sealing was simple and rather fast. I detected no odor with the sealant but my prep, otherwise, was strong as I used old fashion bleach and toothbrush. Great value in my opinion and I would purchase again when needed.

Have bought in the past and came with the sprayer this time it did not. Pretty hard to use the product if you have no sprayer. Not a product you want to have to put into another sprayer. It would be kind of a hassle luckily, I was able to gather the other sprayer I had out of the trash before it went out. The last time I bought, it came with a sprayer.

I was concerned about purchasing a sealer that would cause new black grout to become discolored after sealing it as had been my experience in the past. After doing some research, I learned that as long as the sealer is water-based this would not happen. Even so, I was still skeptical but decided to give BlackDiamond a try based upon other reviews. I applied it to the grout with a paint brush in an inconspicuous spot behind the toilet and was very pleased to find that not only did not change the color of the grout at all, but it did a fantastic job of sealing it. It's an excellent product that is worth every penny and goes a very long way.

My Goo Gone grout cleaner and Stone Works Ultimate grout sealer both arrived on time and well packaged.I followed the directions on the back of the bottles, sprayed the Goo Gone cleaner on and let it sit for a couple minutes, then scrubbed it with a soft kitchen scrub pad and toothbrush, and the dirt and grime from the last 20 months came right off.The most tedious part of the process was using a artist paint brush to apply the StoneWorks sealer, but it's all done.Next month I will probably have the Hydroshield company come to clean and seal my granite countertops, all of my tile in my bathroom, and the glass inside my shower, but these are great products with or without that.

Purchased for floor tile grout. Easy to apply. Once dried looked same as before, so good. Time will tell if protects grout, but so far I'm happy with product.
