Preparation Before Painting
Pressure treated lumber often holds moisture. Check moisture levels with a moisture meter. Wood must be dry before painting. Wet wood can cause paint peeling. Drying time varies. It depends on weather and wood type. Patience is key for a good finish.

Safety is important. Wear gloves and goggles. Protect your skin and eyes from chemicals. Work in a ventilated area. Avoid inhaling fumes. Ensure tools are in good condition. Safety measures prevent accidents.
Ideal Timing For Painting
Drying time depends on several factors. Wood moisture level is key. Higher moisture means longer drying. Weather also plays a big role. Sunlight can speed up drying. Humidity slows it down.
