The Best Granite Sealer is MB-4

MB-4 is the Best Granite Sealer. It requires only one application and it's good to go for 10 years or more

I'm a professional granite installer and in my own home I have natural stone tops in the kitchen, every bathroom, laundry room, outdoors on the deck, even my kids' desks. I have never reapplied sealer in over 9 years. Sealed all the tops one time (granite, limestone, marble) - never a stain, never a dull shine.

Why should you seal granite? Sealing granite is such a misunderstood practice and misused marketing weapon. It's the result of ignorance in the stone industry and malicious intent by sales people of competing countertop materials.

It's generally believed that when a material is delicate and hard to maintain, it needs to be sealed. The stone industry set out to solve the concerns of staining granite countertops by soliciting chemists to find a sealer for stone. Unfortunately, the chemists didn't know the first thing about petrography.

The best performing product we have found is MB-4 Impregnator/Sealer from MB Stone. We have provided this to all our customers as part of a stone care kit when we install a new countertop and when we show them how to clean and seal their granite.

MB Stone granite countertop sealer is superior to other granite sealers. Applied properly, this sealer will last 10 years.
