All Surface Restoration offers pressure washing & sealing services to maintain the beauty & durability of exterior limestone surfaces. No matter how faded, dirty or neglected your limestone is, we can transform it to a like new condition while also protecting it from water penetration & future stains.
Limestone is extremely porous as compared to other types of stone. Limestone deterioration occurs through weathering, pollution, soot & dirt accumulation. Further damage can occur through erosion, as a result of movement caused by thermal expansion & contraction.
Pressure cleaning limestone is essential to keep dirt & pollutants from accumulating. Our cleaning process is safe & will not damage the integrity of the surface. Limestone is especially sensitive to acid based cleaners and should only be cleaned using specially formulated limestone cleaner. The cleaner used in conjunction with soft water washing removes embedded stains safely & effectively.
Exterior limestone surfaces in Michigan should be cleaned & sealed at least once every 2-3 years to protect from water penetration & stain build-up. Pressure cleaning will remove moss, mildew, algae, dirt, rust, black carbon build-up & mineral stains.
After limestone is cleaned it should ALWAYS be protected. Application of Surface Saver Sealer will prevent water infiltration without trapping moisture within the stone. It allows for 100% water vapor transmission. Surface Saver penetrates deep into the limestone forming a lasting bond below the surface. It does not change the natural buff appearance of the stone.
Sealing limestone with Surface Saver Sealer forms a tough barrier that locks out water & stains for an extended period, typically 3-4 years on horizontal surfaces & 5-7 years on vertical surfaces.
If you notice that your limestone frequently develops stains from mildew, algae, dirt, soot or crusts, you should have it sealed to help prevent frequent recurrence of stains. Never trust your limestone to a contractor who is not knowledgeable, trained & experienced in restoring exterior limestone.
