The first step involved identifying all areas of spalled concrete, which were then carefully demolished and rebuilt using a high-strength repair mortar. This process ensured the courtyard had a sound and level foundation before resurfacing began.
To prepare for coating, the entire surface was mechanically shotblasted to achieve a CSP-3 profile, which enhances adhesion for subsequent layers. All cracks greater than 1/16” were routed and sealed with a urethane sealant to prevent future water ingress. Due to high moisture readings in the concrete, a specialized moisture mitigation primer was applied across the surface. This primer acts as a barrier, reducing the risk of future coating failure due to moisture vapor transmission.
Following preparation, DCPS applied a two-component base coat, followed by two successive layers of a high-wear epoxy traffic coating. Each layer received a full broadcast of aggregate to refusal, creating a durable, slip-resistant surface that will perform under the high foot traffic expected in this commercial.
Despite the addition of over 100 square feet of unexpected repair work due to a change order, the DCPS team delivered the project ahead of schedule. Their methodical approach and deep experience with moisture-sensitive installations ensured a long-lasting, high-performance courtyard surface ready for the busy summer season.
