Concrete, coatings and sealers all need the right conditions to cure. In the desert, that makes timing part of the quality of the job.
Season by season
- Fall (October–December): The best window. Warm enough for coatings to cure well, cool enough that nothing dries too fast, and the deck is ready for winter.
- Winter (January–March): Still very good. A rare cold snap can slow curing.
- Spring (April–May): Workable, with earlier starts as the heat builds.
- Summer (June–September): Avoid major work if you can. Ground temperatures are extreme, materials set too quickly, and afternoon storms interrupt.
What the weather does
- Extreme heat: Speeds up drying, which causes cracking and poor adhesion. Crews work early and stop before the worst of it.
- Very dry air: Concrete has to be kept damp or covered so it cures slowly and evenly.
- Monsoon rain: A sudden downpour ruins a fresh coating or sealer.
- Dust storms: Blown dust contaminates anything still wet.
Protecting the work afterwards
Keep the surface clean, reseal every two to three years, deal with small cracks before they grow, and add shade where you can. Rinse off pool chemicals as soon as they are spilled. The deck will look good far longer for it.
