lumber treated with waterborne preservatives contains a good amount of moisture that will affect the penetration and drying of stains and paints. For the best performance of paint and stain coatings, allow treated wood to dry prior to application which is typically 60 to 90 days after installation
Estimating exactly how long treated lumber will take to dry is hard to predict, and will depend on sun exposure, local temperature and recent weather conditions. Take these factors into consideration for your specific installation and use your best judgment. Be sure to follow the stain manufacturer’s instructions for best results.
