Wet lay flagstone patios are made from flagstone which is a hard, flat stone. Flagstone can either be cut or split.
Flagstone patios are becoming more popular because of the distinctive, natural look. It typically comes in red, blue, or buffed colors.
Flagstone is extremely durable and can last for centuries while requiring little to no maintenance.
It also provides a beautiful, natural aesthetic for your patio!
Because flagstone reflects the sun, it can get pretty warm underfoot. Still, flagstone handles different climates well and doesn’t expand and contract when the weather changes.
Flagstone requires little maintenance beyond regular sweeping away of debris that could leave stains or mold on the stone.
Unlike pavers which sometimes need readjustments to keep it level as it settles, a flagstone patio set in concrete results in a permanent patio that requires virtually no maintenance.
Bleach and water will remove most mold stains, but grease or rust stains call for harsher chemicals. Because flagstone is laid in pieces, it’s easy to replace broken or cracked stones without tearing up the whole patio.
A flagstone patio can last a lifetime if taken care of properly.
Flagstone maintenance tip: Don’t seal your flagstone. In the hot sun, sealed flagstone becomes more likely to deteriorate and discolor
