About Black Diamond Granite Countertop Cleaner & Sealer
Overall Feedback:
84% positive
86% appreciated the waterproofing feature
Water beads right up, making it super easy to clean.
After applying two coats of the sealer, water beads up and the color of the stone doesn't change.
71% liked the uv protection feature, but 29% faced issues
Under the can of ice cold soda, I observed the concrete surface darkening and spreading out, indicating inadequate UV protection from the deck-sealer.
74% were satisfied with the maintenance requirements, but 26% encountered issues
I am dissatisfied with the maintenance requirements of the deck-sealer and afraid to reapply it as it may seal in the orange-dye specs and dark shadow stains.
80% were impressed by the durability, but 20% raised concerns
I move the product inside a building for winter, but it lasts all summer.
After applying the product, water does not immediately bead up but eventually gets in.
I am disappointed with the durability of the deck-sealer. I have wasted my money and hours of labor-intensive non-stop applying and buffing. Now, I am using plastic tablecloths on my counters and Island to stop more spots from occurring until I can find something to deep clean and permanently seal.
