2.1 Surface Preparation and Cleaning. a) Thoroughly pressure wash all court surfaces (indoor and outdoor) to remove dirt, mold, mildew, loose paint, and debris. Use cleaning equipment and solutions appropriate for tennis court surfaces. b) Ensure all surfaces are dry, clean, and free of contaminants before proceeding with crack repairs or resurfacing. c) Remove and properly dispose of vegetation, direct, or debris within cracks. 2.2 Crack Repairs. a) Inspection: Identify and mark all cracks and damaged areas needing repair. A joint inspection with the City’s representative is required prior to beginning work. b) Method: Clean cracks thoroughly to remove all loose material and moisture. Fill cracks using a 100% acrylic crack sealant approved for tennis court surfaces. Repairs such as spalls, delamination, potholes, scaling, popouts, and other defects in the substrate must be repaired and all projections must be leveled prior to the commencement of the installation. c) For wide or structural cracks, embed fiberglass or geotextile fabric (.30 Mil thick waterproof fabric adhesive tape six inches wide) with the crack filler to enhance durability and prevent re-cracking. d) Layer crack filler as needed, allowing each layer to fully cure. Sand repaired areas to a smooth finish to ensure a seamless surface transition and proper court playability. 2.3 Leveling Birdbaths. a) Inspect all courts for birdbaths (areas holding more than 1/16 inch of water for over an hour after rain or cleaning). b) Fill depressions using an acrylic binder or leveling compound mixed with silica sand, ensuring a stable and durable repair. c) Sand the leveled areas to create a smooth, uniform surface that complies with NCAA and USTA court standards.
