Historic Surfaces & Materials Commonly found materials in historic buildings include:
- Plaster
- Paint
- Wood Finishes
- Metal
- Marble & other stones

Causes of Deterioration Other Causes
- Structural Issues
- Mechanical Wear
- Natural Aging
- Incompatibility of Materials, Workmanship,
& Alterations
- Environmental Issues
SLIDE 9
Causes of Deterioration - Water Typical Causes
- Infiltration from the building exterior
- Infiltration from mechanical
systems Effects
- Efflorescence & Plaster
deterioration
- Flaking and Peeling paint
- Water staining on finishes
SLIDE 10
Causes of Deterioration – Structural Issues Typical Causes
- Building Movement
- Natural Aging
- Environmental Issues
Effects
- Cracks and unstable elements
SLIDE 11
Causes of Deterioration – Mechanical Wear Typical Causes
- Manual Touch by public
- Moving of Furniture & Furnishing
Effects
- Nicks, Scrapes, & Abrasions
- Losses
SLIDE 12
Causes of Deterioration – Natural Aging Typical Causes
- Normal ‘Shelf Life’
- Exposure (Environment)
Effects
- Material Breakdown
- Finish Discoloration or Degradation
SLIDE 13
Causes of Deterioration – Incompatibility Typical Causes
- Wrong Material
- Wrong / Poor Repair
- Poor Decision
Effects
- Material Breakdown
- Poor adhesion on finishes
SLIDE 14
Causes of Deterioration – Environmental Issues Typical Causes
- Mechanical System Operations / Failure
- Control of Exterior Environment
Effects
- All of the Above
SLIDE 15
Finding Solutions First Step
- Document & Evaluate the Condition Issues
- Look for the Causes
Methods
- Material Assessments
- Lab Analysis
- Environmental Assessment & Monitoring
SLIDE 16
Finding Solutions Material Assessment
- Cursory Survey
- Comprehensive Examination
SLIDE 17
Finding Solutions Lab Analysis
- Determine components
- f original material
- Find elements that could
be contributing to the problem
SLIDE 18
Finding Solutions Environmental Assessment & Monitoring
- Monitor Relative Temperature & Humidity
- Review of Mechanical Systems
SLIDE 19
Environmental Assessment & Monitoring
Temperature & Relative Humidity data collection
- This can be done at any point to create a
baseline of data.
- If setting a survey before an issue arises
then this data can be an early indicator of an issue.
- OR it can be started once an issue is
discovered
- Looking for understanding of how the T&RH
fluctuates in the space of concern.

Environmental Assessment & Monitoring
Tools for Measurement

Environmental Assessment & Monitoring
SLIDE 22
Environmental Assessment & Monitoring
Detailed survey of the space, building and building systems
- Building envelope deficiencies could be directly contributing to issues
through bulk water leaks or excessive air infiltration.
- Building systems could be directly contributing to the issue through
leaks – water, steam, conditioned air, sanitary, storm water, etc..
- Building systems could be indirectly contributing due to poor
performance in removing excess humidity or poor temperature control.
- IR survey to see hot/cold spots behind walls and ceilings.
- Blower door testing.

Environmental Assessment & Monitoring
Sometimes the results are indeterminate / inconclusive In that case, if there is no smoking gun?
- Expanded T & RH Data collection is needed.
- May Require Destructive testing with the use of a
Boroscope
