Why do courts fade, crack and turn slippery?
Sun, rain and shoes wear any court colour over the years, and water standing on the surface shortens its life; the AC25 data sheet asks for the falls and ponding to be put right before coating. Cracks and depressions show through new paint, and algae and old flaking paint make a court slippery.
That is why the work starts with repairs, not colour: failed paint, algae and contamination removed, cracks and depressions repaired, and ponding corrected, so the new coats bond to a sound, clean, dry surface.
