Coatings Evaluation

Coatings like paint, primer, epoxy, and polyurethane enhance the durability and finish appearance of structures and materials. In both architectural and structural applications, these protective layers shield substrate materials from environmental exposure and deterioration. However, material incompatibility, improper installation, age, and other factors can lead to distress in coating systems themselves. Our extensive materials expertise and field and laboratory testing capabilities help clients determine the types and sources of coating distress and inform selection of effective repair approaches.

Existing conditions are assessed in the field and, if necessary, samples of the finishes and substrate are removed for laboratory analysis in our Janney Technical Center laboratories. Materials are assessed as components of systems and individually to determine their condition and history. Once the existing coating, finish, or material has been characterized, we develop substrate preparation and coating approaches that are sensitive to the material—and, when appropriate, to its historic character—while considering durability and compatibility with the existing substrate.

Our professionals regularly assess coatings and finishes applied to concrete, stone, brick, tile, metal, wood, art glass, plaster, and stucco. We also specialize in immersion-grade coatings and linings systems that inhibit the ingress of chemicals as well as passive and active cathodic protection systems to counter the effects of corrosion.
