Limestone and sandstone have distinct differences in terms of strength and durability. Limestone, as calcite rock, is known for its durability and ability to withstand weathering. It's relatively resistant to damage so it's suitable for various applications, including limestone pavers. On the other hand, while sandstone is generally strong and ... Adding stone steps is a great way to elevate the look of your home.

Step 3: Cut - Guide the limestone through the wet saw to cut it. Avoid the temptation to push it through quickly because that will likely cause chipping and cracking at the second edge. Allow the saw to do the work for you. Step 4: Shape - One other step that can be taken is to use a sander to smooth out the edge.Crushed stones #2: ½″ to 2-2/2″ wide.
