If you’re looking for a granite sealer, Consumer Reports has you covered. We tested three popular brands—Granite Gold, Miracle Sealants, and Rock Doctor—to find the best granite sealer.
Here’s what we found:
Granite Gold: This sealer was easy to apply and left our countertops looking shiny and new. It also repelled water and oil, making it a great choice for busy kitchens.
Miracle Sealants: This sealer was a bit more difficult to apply, but it did an excellent job of repelling water and oil. It also left our countertops looking shiny and new.
Rock Doctor: This sealer was the most difficult to apply, but it did an excellent job of repelling water and oil. It also left our countertops looking shiny and new.
So, which granite sealer is the best? All three brands did a great job of repelling water and oil, and they all left our countertops looking shiny and new. However, we think Granite Gold is the best choice because it’s the easiest to apply.

- ✅ Professional Quality Stone Care – TriNova’s Granite Sealer & Protectant offers a premium sealant and caring solution for your premium stone surfaces, including marble. Whether you’re looking for a sealing product for the first time or a resealer for long-lasting protection, this product can give your granite surfaces the before and after results you want to see. Great for Quartz, Marble, Granite, Quartzite, and Soapstone.
- ✅ Advanced-Action Stain Protection – This spray uses a powerful blend of polymers to penetrate the stone’s naturally porous surface to block out stains from seeping in and becoming permanent. By doing this, TriNova’s Granite Sealer also provides a protective layer on top of the granite to prevent water spotting and to keep other residue from sticking.
- ✅ Enhancing Formula for Gloss & Shine – TriNova’s Granite Sealer & Protectant is essential when the time comes to treat all types of stone and to enhance surfaces for a polished and natural look. It also works miracles on grout to guard against stains that develop between your shower or bath tiles that can be the most difficult to remove with your hands and a sponge, no matter how hard you scrub.
- ✅ Do the Water Test - The best test to see if your granite needs to be sealed is to put drops of water in certain sections of your granite and wait 30 minutes. If the granite absorbs the water, you need to reseal. If not, your granite is protected. However, we still recommend using the Granite Sealer at least once a month to prevent stains from happening in the future.
