Ash in the joints after a brush fire
When the Everglades burn west of Sunrise, as they did in June 2026, ash falls on pavers and washes into the joints with the next rain. It mixes with the joint sand and whatever algae is growing there, and it turns the joints dark grey. Light pavers show it most.
Before sealing, the joints are blown out and the pavers cleaned so none of that is locked in. Fresh polymeric sand goes back in, then the sealer. Sealing while ash is still falling nearby is a waste, so the timing follows the fire season. The same goes for a wet stretch of summer: sealing waits until the pavers have dried out. If the joints are only partly filled, the fresh sand brings them back to full height before sealing.
