Sequential Approach to a Concrete Floor Condition Assessment
Abstract
This report presents a sequential approach to assessing the condition of concrete floors. The condition assessment is to be performed prior to specifying either an initial coating system or an overcoat to an existing coating system. The condition assessment is designed to identify problem floors and eliminate premature coating failures resulting from the following practices: (a) overcoating unsound coating systems, (b) coating concrete with low surface strength, (c) coating concrete with high levels of surface contamination (oils, fuels, fats, waxes, etc.), and (d) coating concrete with a high rate of moisture vapor emission. The condition assessment consists of eight tasks: (1) identify concrete surface texture, (2) identify chemicals and exposures, (3) identify service conditions, (4) measure floor dimension, cracks, joints, and specific defects, (5) determine rate of moisture vapor emission, (6) determine concrete surface strength, (7) determine depth of surface contamination, and (8) determine adhesion of existing coatings. Results from the condition assessment are to be used in specifying appropriate concrete repairs, determining a suitable level of surface preparation, and selecting a proper coating system.
