Sandstone, flagstone, limestone, travertine, slate and bluestone are just some of the many different types of natural stone or rock used in masonry construction. Natural stone is usually quite durable and is often used for many projects like stone walls, pool decks, water features, patios and sidewalks. Most problems with natural stone occur not with the stone itself, but with the porous mortar that holds it together. Unsealed mortar will quickly absorb water from rain and snow. When this moisture freezes and expands, it can cause cracks to form and can even cause the entire structure to break apart. A water-repellent sealer will stop the water from absorbing and will prevent this type of damage.

All natural stone surfaces need to be sealed periodically. This is because stone is naturally a porous material and can absorb bacteria, food particles, and liquids that we use throughout our home. The good news is that sealing your stone surface won’t cost a fortune. Sandstone surfaces, due to their porous nature, can become stained very easily. Any oil or grease spill will absorb into unsealed sandstone, but remain visible on the surface.
