Learn by doing in this full-day workshop with opportunities to use cleaning materials and tools to address staining and deterioration conditions frequently encountered on historic masonry structures, including urban grime, mold and mildew stains, and paint and graffiti removal. Additionally, there will be demonstrations in the use of various materials and techniques for masonry repair and repointing.

The workshop will begin with a classroom component to introduce the features and format of the workshop. Then, it will move outdoors on the grounds of the Texas Historical Commission’s French Legation State Historic Site, and will include a short “hard hat” tour of the site, which is currently closed to the public during ongoing preservation work. Come prepared with weather-wise clothing and shoes suitable for a muddy jobsite.
