Our Process


Our Process for Cleaning Stone & Applying Sealant

Flagstone is the most common type of stone used in outdoor patios, decks, and outdoor features. The term “Flagstone” actually refers to the cut of the stone, not the type of stone. Flagstone is almost always a Sandstone. Flagstone refers to the cuts and the installation with large irregular shaped pieces of stone and large grout lines. Any stones can be cut and installed as a Flagstone pattern.

Sandstone is a sedimentary stone that is deposited as mountains are turned into sand grains by erosion. After time, the sand grains are compacted together and bonded together by minerals to form a solid rock.

Flagstone and Spalling

Flagstone is very susceptible to erosion and spalling. Spalling is when water erodes the bonding molecules that hold the sand particles together and the sandstone starts to peel off in layers.

If the stone is treated with a sealer, spalling might never occur. Once spalling occurs (and it will if the sandstone is exposed to the elements) there is permanent damage that could have been avoided or delayed for decades instead of occurring in years.

Cleaning & Sealing Process

Our Flagstone cleaning process is very aggressive. We use a chemical cleaner with a surface cleaner and hot water to remove oils, dirt and any loose stone. We then inspect the surface for layers that are peeling off and need to be removed before the sealer can be applied.

Once all the loose debris has been removed and the stone is dry we then soak the stone with as much sealer as it will absorb. We apply an ample amount of sealant, or as much sealant is necessary to seal each particular type of stone and we stand behind our written guarantee. We perform a manual compound acid scrub that consolidates and clarifies the sanding and stone.

Flagstone installed as coping on pools, especially saltwater pools, should always be sealed. This will give it protection from chlorine, saltwater penetration and stains. Sealers are not bulletproof and once a sealer is applied it needs to be maintained regularly. It will generally need to be applied every 5-7 years depending on the condition of the stone when first applied.

Special note: Drying times – Depending on humidity and average daytime temperatures the sealer should be fully cured prior to water contacting the surface. Full cure is generally achieved in 72 hours. If there is a possibility of rain within the 72 hour cure time, we cover the surface so it will remain dry. However, in Texas with the temperature above 90 degrees drying time can be achieved in much less time.
