TYPES OF
DAMAGE

Without proper protection, exterior building stone can develop many types of damage. From staining to mold to leaching efflorescence, all are caused by allowing water to penetrate the stone.

STAINING

Without protection, vehicle exhaust, tree sap, fluid from leaking vehicles, and other environmental contaminants will adhere to stone surfaces. This collection of dust, dirt and oils causes unsightly stains on the building and walkways.

MOLD & MILDEW

There are many types of mold and mildew, but no type will grow unless moisture is present. Sealing exterior building stone prevents water penetration and eliminates these green and black stains from forming on the architectural surface.

LEACHING

Efflorescence is a white, chalky substance that appears on exterior building stone when moisture in the stone is drawn to the surface and evaporates leaving salt deposits behind. These minerals can continue leaching down and also stain nearby glass, metal or other architectural materials. Protected masonry helps prevent stone as well as other building surfaces from needing future restoration.

WATER PENETRATION

If water is able to penetrate the building stone, it will begin to erode the bond that holds the masonry together. This is especially damaging during the winter months when the water freezes and expands, compromising the strength of the manufactured stone. The resulting cracks and separation of material components can lead to costly repairs.

structuraL

If water is allowed to penetrate beyond the building masonry and reach the steel components that hold the building together, the steel will begin to rust. This issue, left unresolved, can lead to structural damage as well as further staining.

PROTECT YOUR
INVESTMENT

Whether you own one building or an entire portfolio of properties, we know that what's most important is ensuring your investment grows in value. Selecting the right restoration and protection methods will have a positive economic impact for years to come.

High-Performance Results

Chemical cleaning is the most cost effective and efficient means of removing severe stains from a building’s stone surfaces. Stone cleaning can be performed with high or low pressure techniques depending on the type of stone. Presto technicians carefully select the right combination of pressure and chemical cleaning technology, making sure to effectively clean the stone without wearing away the surface.

Presto’s technicians are also thoroughly trained in safety-compliant cleaning and restoration methods to ensure your protection of pedestrians and other elements on the property.

Long-Lasting Protection

A high-quality restoration is not truly complete until the stone surfaces have been sealed. An invisible protective coating will prevent water penetration and erosion as well as resist staining from mineral deposits, biological growth and other environmental contaminants. Applying a clear water repellent will ensure the greatest return on investment for your property’s stone cleaning or restoration services. Sealed stone prevents the need for frequent pressure washing, as any settled dirt or contaminants easily rinse away.

Presto products contain high-quality silicone and acrylic coatings designed to close the pores of the stone and provide durable, long-lasting protection.

Exceptional Warranties

Presto provides a 10-year warranty on all stone sealant products. And we always make sure our clients are armed with the proper maintenance knowledge to extend the life of these protective treatments. Presto’s detailed recommendations will show how to correctly clean the stone without damaging the protective coating. Plus, if the stone is properly maintained, an extensive restoration should not be needed again.
