The Best Way to Protect Sandstone and Limestone Against Salt Damage

When it comes to salt, most people think of the white stuff that we sprinkle on our food. But salt can also be a serious problem for stone surfaces like sandstone and limestone. If you live in an area with a lot of salt in the air, like near the ocean, your stone surfaces are constantly under attack from salt. Over time, this salt can damage the stone, making it more susceptible to stains and eventually causing it to crumble.

Fortunately, there is a way to protect your sandstone and limestone from salt damage: seal it. Sealing your stone will create a barrier that will prevent salt from penetrating the surface and causing damage. There are a variety of sealers on the market, so be sure to choose one that is specifically designed for sandstone or limestone.

Sealing your stone is a simple process, but it's important to do it right in order to get the best results. First, make sure the surface is clean and dry. If there is any dirt or debris on the surface, it will prevent the sealer from bonding properly. Next, apply the sealer according to the manufacturer's instructions. In most cases, you will need to apply multiple coats, letting each one dry completely before moving on to the next.

Once the sealer is dry, your sandstone or limestone will be protected from salt damage. You'll still need to take care of it, of course, but sealing will give you some peace of mind knowing that your stone is salt safe.
