When a masonry project is completed, P&G will combine the project with a waterproofing procedure to ensure effects of water entering and damaging your structure in the future. Water damage can have lasting effects on your property. Waterproof coatings seal the surface from liquid water and from water vapor. They are usually opaque, or pigmented, and include bituminous coatings and some elastomeric paints and coatings. P&G ensures that all the precautions listed in the Material Safety Data Sheets are followed and that they are always available to the customer when asked.
