Whether you’re using granite countertops or marble floors, it’s essential to take good care of natural stone with the help of a reliable sealer. This product protects the natural stone surface from contaminants that are able to slowly seep into it. There’s no way around using a sealer product considering the porous nature of stone that makes it highly susceptible to staining and damage. Some types of stones can feature greater porosity which translates to additional vulnerability. In any case, it’s recommended to find a solid stone sealer to reinforce the surface of your floors, walls, and countertops.
The popularity of natural stone in the world of interior design helped to create a big market for stone sealers. This can make it very challenging for regular homeowners to figure out which product works best for their needs. Most choices can be broken down into coating sealers and impregnating sealers. The former is based on simple-to-apply coatings for convenient and inexpensive protection. Coating sealers are typically used for flooring and countertops. They can require some extra maintenance work. Impregnating sealers are more expensive and challenging to use. They’re more durable and reliable against water and oil damage.
