Finally catching up on some interesting projects. This one was a little different, in that we did this project some time ago, but I have returned recently for an inspection of another project. While there I was able to see how the cleaning and sealing of the exterior porch, walls and pillars were holding up. Exterior cleaning is most typically done via high pressure alone, I see it all the time. When that method is used, you usually see the marks or patterns the technician haphazardly placed into the surface. De-greasing or loosening of the embedded soils is a very important part of exterior cleaning, but usually ingnored. I will not give a lesson on exterior stone cleaning with this post, but I wanted to show the difference when a plan is executed properly. After the surface was dry, we applied a special exterior sealer that will prevent the future growth of mold and mildew. Two years later the pillar in this picture looks the same!!
