How to Control Moisture Before Painting Concrete
Moisture is one of the leading causes of coating failure on concrete surfaces. Controlling moisture before painting ensures long-term adhesion and prevents blistering.
Begin by testing the floor for moisture using either a moisture meter or a plastic sheet test. If moisture levels are too high, address the cause. This may include improving ventilation, repairing leaks, or allowing more drying time after cleaning.
If the floor is new, allow proper curing time before painting. Older floors may retain moisture due to trapped water or poor drainage. Once moisture levels are acceptable, prepare the surface with mechanical abrasion and apply the coating system following recommended conditions.
Monitoring humidity and temperature during application helps ensure proper curing and long-term performance.
