No mystery to it. Here is exactly what happens from the moment you call to the moment we hand the job back.
Cracks evaluated for movement and the court flooded to reveal where water stands. Both determine scope, and both should happen before a firm price is given.
Pressure washing, removal of organic growth, and scraping of any delaminating existing coating. Adhesion depends entirely on this step.
Cracks routed and filled, or bridged where they move. Birdbaths patched and feathered, then re-flooded to confirm the water now drains.
Acrylic resurfacer squeegeed to level texture, then color coats. Each layer needs to cure and weather conditions govern the schedule tightly.
Lines laid out, taped and painted to specification, then the court left to cure fully before play. Playing early scuffs coatings that have not hardened.
None of this is required — it just makes the visit quicker.
