Coatings and Sealant

This case involved paint peeling from galvanized metal panels. Gerald Zakim Associates tested both the paint and panels in question, and found the contractor had painted over old paint.  Though it appeared to be sound, the adhesion was so poor that new paint coating, while compatible, pulled the old paint off during its drying and shrinking process. Due to GZA’s recommendation, the building was sandblasted and properly repainted.
