As a building ages, the masonry collects a film of soot, dirt, and airborne pollution, including oil by-products from vehicle emissions. These pollutants can trap moisture within the porous masonry which can lead to deterioration.
This soot can be removed gently without abrasive sandblasting using special cleaning solutions. Chemical cleaning often restores the lost appearance of a building's former detail and brings back to life lost colors. J.W. Waterproofing uses blends of proven cleaning chemicals to gently remove the soot and restore the building's beauty.
