Our Flagstone cleaning process is very aggressive. We use a medium to heavy custom abrasive process to sand away any loose surface to expose fresh stone. During the sanding process the stone is washed with our truck mounted cleaning equipment. We inspect the surface for layers that are peeling off and need to be removed before the densifier is applied.

Unique Two-Part Sealing System: Why Replace when you can Protect?

Exterior 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 (see photos below. If the stone is treated with densifer, 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.

Spalling is the crumbling process typical with flagstone that is not protected from the elements.

Does your patio look like this? Water exposure, heat and sun will speed up erosion. Spalling is flaking off in layers, as seen in the two examples above.

Stone Densifier: Unique — We Invented It!

Our goal is to protect and extend the life of your patio so you can enjoy it! The old standard way of sealing flagstone was to apply a penetrating sealer alone. This just wasn’t offering the protection needed in our harsh environment.

We kept seeing heavy erosion on every patio we visited. We didn’t feel good about applying a useless penetrating sealer, knowing it did little good, so we stopped sealing patios altogether. Then Tom did some research and experimenting and came up with our Stone Densifier. After a good amount of testing under the elements, we started offering this treatment in 2010 with great results.

How it works~ Stone Densifier penetrates deep into the stone, rebonds the sand particles and reinforces the bonding molecules already there. It helps to seal the the stone by occupying voids between the sand preventing water from getting in and causing damage. The patio is harder overall and more resistant to chipping and flaking.

Enhancing Sealer

After the Stone Densifier we soak in an Enhancing Penetrating sealer to help slow water absorption. This product becomes more effective when used in conjunction with the Stone Densifier. The colors will be slightly enhanced, keeping it very natural looking.
