Many commercial buildings are made of precast, a porous material with a composition of sand, gravel and crushed stone held together by cement.  

A precast panel was sealed on the left with Presto Restoration's Leachstop® silicone sealer the day before. Water was applied to both sides to demonstrate the effectiveness of the protection. The left side demonstrates how precast protected with LeachStop® repels water and remains protected from damaging elements. The right side shows how water soaks into the unprotected precast and darkens it, also allowing dirt, pollution and contaminants into the pores of the precast. 

After cleaning and/or restoration of precast, it is vital to seal the surface of the stone composition to help prevent immediate precast leaching and water penetration. If not, the precast acts as a sponge, and creates a breeding ground for biological growth. Sealing also closes the pores of the concrete so that water is not able to freeze and thaw creating precast spalling or chipping. 

Presto's LeachStop® is a revolutionary sealer that carries a 10-year warranty. Imagine a freshly restoration commercial high-rise building that looks clean and protected for an entire decade and beyond.

Interesting enough, while Presto cleaned and sealed the precast on the Omni Hotel in 2008, notice how it STILL looks great after using Presto'sLeachStop sealer.  Eight years later and counting, the precast remains stain-free.

Over the years at Presto Restoration Products & Services, we have witnessed countless commercial buildings with precast sealed with silane. This material performs poorly, causes stains on glass and metal surfaces and is harmful to the environment. Unfortunately, the water repellent most commonly used today to seal architectural stone consists of 40% solid content silane. In our experience, 40% silane is one of the least effective product options available for vertical precast surfaces, especially when flush-mounted windows are present. 

September 2015, Presto Restoration Products & Services completed an extensive glass, metal and precast restoration project of the North American Mission Board (NAMB) in Alpharetta, Georgia. The entire building’s exterior surface, including glass, metal and precast concrete was restored and protected using Presto's uniquely designed product line. Nearly 8 miles of caulking was replaced using Dow Corning 757 SMS silicone caulking a unique silicone caulking that reduces residue rundown and substrate staining. The building’s glass, metal and precast surfaces were restored and protected as well and covered the distance of two football fields.

Many high-rise buildings are constructed similarly and the windows are typically cleaned in a traditional manner every six months only to develop stains on the glass, metal and precast surfaces within a couple of years after construction. By maintaining the building’s exterior with Presto Restoration Products, the NAMB building can preserve its original appearance and will prevent unnecessary and expensive restoration services from ever being performed again, if maintained properly.

After over a decade of continued use and testing, case-study after case-study proves that Presto’s protective treatments and maintenance process allow building facades to remain stain-free.

The following services were performed using the following products:
