Sandstone is a sedimentary rock that consists of finely ground quartz grains. This type of stone has been used as an architectural building material for centuries, and it continues to be so today with its modern applications in construction materials such as concrete or masonry.
If you have sandstone that has been damaged, you can use a “sandstone repair kit” to fix the issue.

- With a pneumatic hammer and chisel, chip away at the stone outlined by the diamond cuts.

What, after all, causes sandstone to crumble?
Excessive spalling may lead to the collapse of a building. Water penetrating brick, concrete, or natural stone causes spalling, which is also known as spaulding or spalding. It causes the surface to peel, pop out, or flake off as a result of the pressure. It’s also known as flaking, and it’s particularly common in limestone.
