1. How do you prepare pressure treated wood for painting?

Pressure treated wood requires proper care before it can take on a paint coating. You need to clean the wood surface, allow it to dry properly, and apply primer, before you can use your paint coats.

Although the pressure treatment protects the wood from termite and decay, a sealer is necessary to control cracks or splitting of the wood surface. And the sealer enhances the appearance of the wood.
