True or False: Wood siding that will be painted does not need to be primed before installation.

Wood siding that will be painted should indeed be primed before installation. Priming serves several important purposes that enhance the longevity and appearance of the painted surface. First, it provides a uniform surface that helps the paint adhere better, ensuring that the finish will last longer and reducing the chances of peeling or flaking. Priming also helps to seal the wood, preventing moisture penetration, which can lead to wood deterioration over time.

Additionally, the primer can help to block tannin bleed, which occurs when natural oils and compounds in the wood seep through the paint, potentially discoloring it. By applying a primer, you create a barrier that mitigates this issue, resulting in a cleaner and more consistent color after painting.

While there may be some instances where certain types of pre-primed siding are available, for most wood siding applications, priming is a crucial step that should not be overlooked.
