Don’t Paint That Pressure Treated Wood Until It’s Ready — Pete The Painter

Pressure treated wood is the ideal option for outdoor projects like fencing panels. Pressure treated doors do not have to be sealed, painted or stained however, this may help protect the door against the elements and extend the longevity of the product. You can’t let it dry out before installing unless you can apply a serious amount of pressure on all sides of the wood. This is important on wood that people will be touching, such as decks, porches, and outdoor railings.

The point I’m trying to make is that someone with the necessary knowledge and experience to build you a safe deck is not going to be cheap. Once you’ve given due attention to the entire surface, rinse off the wood and allow it to dry thoroughly. An exterior all-acrylic latex house paint would be the best choice for painting pressure-treated wood. However, once the surface oil evaporates, treated timbers ignite no more easily than untreated wood. Over the centuries, various practices have been used to protect wood from such attacks.

Cover lumber stored in an open area with a material that will give protection from the elements, but be porous enough to allow moisture to escape. He assured me that the only lasting way to treat wood is with a mixture of engine sump oil and creosote! First is the use of pressure-treated wood in place of Douglas fir for sill plates in new construction.

Do not use treated wood where it may come in direct or indirect contact with public drinking water, except for uses involving incidental contact such as docks and bridges. It is not recommended to paint a deck unless it has some protection from the weather. Bark prevents the penetration of preservative and even small patches will have untreated wood underneath. Pressure treating with waterborne preservatives forces large amounts of water into the wood.

Landscape timbers should be pressure treated to AWPA or federal specifications for use in ground contact. As small cracks develop on the deck’s surface from exposure to sun and water, water passes through and the paint soon peels. The wood is treated successively in two waterborne salt solutions that react with each other to form an insoluble compound. Wood products for construction are typically treated in a factory, using a pressure process.

Composite decking, made of a combination of wood and plastic, is impermeable to insect damage, will not rot or splinter; it’s also resistant to fading and moisture. Ecolife treated wood exhibits reduced cracking, warping and splitting in service, and uses no more chemicals than is absolutely necessary. Cover CCA-treated wood used for raised garden beds or borders with heavy plastic to prevent contact with garden soil. However, always check the label on the paint can to be sure it is recommended for use on wood products. Sharp instruments such as tongs should not be used to handle the wood, and throwing or dropping treated wood should be avoided.
