Flagstone, also known as sandstone, Arizona flagstone, Santa Fe flagstone, or Oklahoma sandstone, is one of the most popular material choices for paving and building in Texas. Flagstone is a type of sedimentary rock that contains quartz and feldspar. Because of this, flagstone is prone to weathering and erosion overtime, which is why sealing flagstone patios, tiles, flooring, or pool decking is highly recommended.
Flagstone Vulnerabilities & How to Prevent Damage
The biggest vulnerability of flagstone is its tendency to develop water stains. The damage can be even more severe if the moisture contains minerals, or is alkaline.
Because of its versatility and generally inexpensive cost, flagstone is a very popular type of sandstone. But, like all other types of stone, flagstone is vulnerable to wear and tear caused by the natural elements.
