Who is responsible for repairing defective concrete before applying a liquid coating?

• A. General contractor
• B. Concrete contractor
• C. Roofing contractor
• D. Site supervisor

Answer: (B)

The responsibility for repairing defective concrete before the application of a liquid coating typically falls to the concrete contractor. This is because the concrete contractor is specifically skilled and trained in working with concrete, including identifying and addressing any defects that may compromise the integrity of the surface. Ensuring a sound, defect-free substrate is critical for the successful adhesion and performance of the liquid coating. By addressing any cracks, spalling, or other imperfections in the concrete, the concrete contractor lays the groundwork for a proper installation, which is essential for preventing future issues such as water infiltration or coating failure. The roles of the general contractor, roofing contractor, and site supervisor, while they may be involved in different aspects of the construction process, do not typically include the specialty knowledge required to effectively repair concrete.
