Photograph of  peeling paint on a building exterior - can you diagnose this failure by eye? Invasive Methods to Find Causes of Paint Failures - Paint Failure Indicators

  • POST a QUESTION or COMMENT about special methods to diagnose the causes of paint failures such as peeling, cracking, bubbling on buildings or other surfaces

This article describes how to use more thorough, invasive measures (removing paint, making test openings, scratch test, peel test, solvent tests) to diagnose the cause of exterior & interior painting mistakes.

This article series describes how to diagnose paint failures on buildings, and outlines a procedure for diagnostic field inspection & lab testing of failed painted surfaces. We include photographs of paint failures on buildings and more photos of forensic paint laboratory examination of samples of failed paint useful to assist in diagnosing the probable cause of each type of paint failure.

The examples use building exterior paint failures (and remedies), but many interior paint failures are similar their origin and cure, including general information provided by some paint manufacturers, home improvement suppliers, and by National Forest Products Laboratory experts.

List of Paint Failure Indicators That Can be Observed Where Demolition is Allowed

If you are able to use invasive methods such as removing siding or cutting openings into wall cavities from a building interior, the diagnosis of cause of failing paint on building surfaces can be supported by very strong evidence. Here is a list of what to look for when using modest demolition or invasive building diagnostic methods:

The diagnosis and cure of paint failure on buildings, particularly on wood siding and trim, is quite possible if there is a careful and thorough inspection of the building, its history, its surfaces, and the actual points of paint failure. It is diagnostic to compare the same coating on the same type of surface at different locations on a building and in areas of failed and not-failed paint.
