Decks and patios in the Texas sun
Outdoor living in Dallas runs most of the year, which means decks and patios take sun, rain, grill grease and spilled drinks almost year-round. A wood deck grays and grows mildew in the shade of the house. A composite deck resists rot but still collects pollen, mildew and grime in the grooves. A concrete or flagstone patio darkens under the table and around the planters.
Wood decks
Cedar, pine and hardwood. Cleaned gently with a wood cleaner and brightener, then left to dry before sealing.
Composite decks
Cleaned by the manufacturer's care guide, which limits pressure and the type of cleaner. Too much pressure can mark the surface and affect the warranty.
Concrete patios
Surface-cleaned like a driveway, with grease from the grill area treated first.
Pavers and flagstone
Cleaned at moderate pressure so joint sand and mortar stay where they belong, and re-sanded if needed.
