AGENDA

 
Friday, May 3, 2019
8:00 – 8:30 am    Registration, Coffee and Continental Breakfast

8:30 – 9:00 am    Welcome & Introduction
Presenter introductions, sponsor acknowledgements, learning objectives and introduction to the workshop beginning with the overarching questions – “Why Clean?”
Amy Lamb Woods, P.E., International Masonry Institute

9:00 – 9:50 am    Understanding Your Substrate    
An overview of the geology and material properties of the substrates to be cleaned – stone, brick, terra cotta and concrete/cast stone.  Risk factors and counter-indicators for cleaning different types of materials – such as hardness or chemical interactions – will be discussed, as well as available test methods for substrates and their potential benefits to developing a cleaning program.
Amanda Thomas Trienens, Cultural Heritage Conservation, LLC

9:50 – 10:40 am    Types of Soiling
The appropriateness and efficacy of different cleaning methods are directly related to the type of soiling to be mitigated or removed.  This presentation will review the nature of different types of soiling – dirt/soot, efflorescence, salts, biologics, metallic or mineral staining, and graffiti, other paints and coatings, whether visible or not – and their susceptibility to removal.
Sarah Holder, PROSOCO, Inc.

10:40 – 11:00 am    BREAK

11:00 – 12:00 pm    Cleaning Methods Overview
An overview of currently available cleaning methods, how they work, and their suitability and risks for different substrates and soiling.  Methods to be presented include:
•    WATER – misting, low and medium pressure, hot water/steam, detergents; 
•    CHEMICAL – acidic, alkaline, chelating agents, solvents, biocides, and poultice methods;
•    MECHANICAL – dry hand tool methods, and wet and dry micro-abrasive systems; and
•    Laser systems

New developments in research and/or trials on masonry cleaning will also be discussed.

Roy Ingraffia, International Masonry Institute

12:00 – 1:00 pm    LUNCH (provided)

1:00 – 1:30 pm    Cleaning Parameters and Protocols
This presentation considers a number of parameters that surround and affect decisions on cleaning – beforehand and during the cleaning project.  These include aligning the purposes of cleaning with expectations, who makes decisions and when, applicable standards, methods of specifying cleaning, developing a cleaning plan, and field considerations such as sequence of work, environment condition, protection, and field testing and mock ups.
Amy Lamb Woods, P.E., International Masonry Institute

1:30 – 4:00 pm    Demonstrations
Attendees will rotate through demonstrations of various cleaning methods by experienced contractors.  Most demonstrations will be performed on the actual masonry of the building.  Demonstrations will include the following categories of cleaning methods:
•    Water, steam, mist methods
•    Chemical methods
•    Micro-abrasive methods
•    Poultices and latex waterless methods
•    Laser cleaning methods

4:00 – 4:30 pm    Q&A Panel Discussion

The day’s activities will conclude with a 30-minute panel discussion with the workshop speakers.

4:30 – 6:00 pm    Cocktail and Appetizer Reception
Continue the dialogue with the speakers, demonstrators, sponsors and attendees over drinks and light appetizers.
