Limestone needs to be sealed in order to last as long as possible. It maintains the natural appearance of your stone, and can prevent it from getting stained. Even dirt and water can cause a form of “crystallization” within the pores of your limestone, creating detrimental and unsightly stains.

How often does limestone need to be sealed?

The sealer should be applied when the limestone is installed and every two years after that to maintain the beauty of the stone. You will know when your limestone tiles require resealing by the way any water sits on the stone. Water on a protective seal will bead.

How can you protect limestone from weathering?

This is a common problem which is seen especially on the limestone walls which suffer substantial deterioration. You can avoid this problem by building a kind of a shelter above the limestone walls in order to protect them against rainwater. Or you might restore them if the weathering is on a deeper level.
