How To Install Outside Trim Made Of Pressure-Treated Wood?

Pressure-treated wood is suitable for exterior trim due to its resistance to decay and insect damage, making it suitable for outdoor applications. The pressure treating process is designed to pull the treatment chemicals into the wood, making it easier to adhere to paint. However, pressure-treated wood may not be the best choice for exterior trim due to its rough appearance and tendency to rot.

For decks, railings, playground equipment, fences, garden beds, and other wooden structures, pressure-treated wood is necessary to stave off life-shortening threats. Softwood lumber, typically southern yellow pine, is chemically treated to resist rot, decay, and termites. General Contractor Jeff Sweenor explains how to use pre-primed, pressure-treated pine for exterior window trim and door casings.

To install pressure-treated wood, trim around windows and doors before siding goes on, put flashings on over door and window trim, and prime it with an exterior oil primer. Cedar or redwood will hold up better than most woods, and white aluminum or PVC can be used as a long-lasting material.

To use pressure-treated wood on trim, prime the wood first and then paint it. Composite and fiber cement are good choices, but they are more expensive than the cheapest exterior grade wood trim, including finger-jointed. Caulk exterior siding and when to caulk pressure-treated lumber is essential, and the glue should bond fine as long as dry, clean, and flat wood surfaces are provided.

Pressure-treated wood is just pine and rots fairly quickly compared to untreated cypress. Learn when to use both types of lumber for your project and ensure a smooth project.

Can I use pressure-treated wood for exterior trim?

Pressure-treated wood is not suitable for finish work due to its greenish tone and need for priming and painting before use. This adds time and expense to the project, and can cause splitting and patching issues. Chemical leaching from the chemicals used in pressure-treated wood can affect soil, plants, and landscaping. Although new compounds used in pressure-treated wood are not as hazardous as earlier ones, the heavier treatment can cause environmental concerns.

Many homeowners are becoming more environmentally conscious and prefer preservative-treated wood like XT Trim produced by Belco Forest Products. This non-toxic material resists moisture and insect activity, making it attractive, easy to work with, and comes pre-primed and ready for installation. It is faster to work with, eliminates the priming step, and is produced responsibly.

What to use to fasten exterior trim?

The area is susceptible to water infiltration, which may result in premature deterioration and rot. The area displays indications of being in a state of deterioration, yet further examination is necessary to ascertain its precise condition.

How do you make pressure-treated wood last outside?

This guide aims to provide a comprehensive understanding of the lifespan of pressure-treated wood, a popular choice for outdoor structures like decks, fences, and pergolas. Pressure-treated wood is lumber infused with preservatives to make it resistant to decay, rot, and insect damage. The treatment process involves placing the wood in a pressurized tank, where the preservatives are forced deep into the wood fibers. This creates a barrier that repels moisture, fungi, and insects, making pressure-treated wood an ideal choice for outdoor construction.

Regular cleaning, application of a protective finish, proper installation, prevention of water pooling, and regular inspections are essential steps to maximize the longevity of pressure-treated wood structures. By following these guidelines, you can ensure your wood structures stand the test of time and provide a long-lasting, durable solution for your outdoor construction needs.

What is the best fastener for exterior trim?

Stainless steel nails are the most suitable fastener for basic construction, such as building a box, and are used in framing and structural applications. Outdoor applications require stainless or galvanized nails, while finish nails are best for trim and molding, furniture assembly, and outdoor projects. Deck screws, coated to resist corrosion, are less expensive than stainless steel nails and are suitable for attaching deck boards and outdoor furniture.

Stainless steel screws are the best fattener for joints that will be subjected to multiple directions of force or extra weight, such as a bookshelf. They grip and bite into the wood, resulting in stronger and more secure joints. However, using nails in these situations can lead to substrates disconnecting. Overall, stainless steel nails are a cost-effective and reliable fastener for various construction projects.

Is it better to nail or screw pressure-treated wood?

Coated outdoor screws are a suitable choice for pressure-treated wood or outdoor decking due to their resistance to staining and corrosion. FenceWorks NW, a veteran-owned company with over 50 years of experience, uses coated screws for fence construction. The choice between galvanized nails and coated screws depends on personal preference, but the best choice is one that extends the structure’s lifespan.

What is the best sealant for pressure treated wood?

Cuprinol Wood Preserver is a clear deck sealer suitable for pressure treated wood and both exterior and interior wood types. It protects against decay, rot, and mold before painting, staining, or varnishing the deck. Barbettine Decking Oil offers anti-slip properties, UV protection, and reduced water absorption rate. When choosing a deck sealer, consider factors like UV protection, water absorption rate, and deck sealer compatibility.

Can you use regular nails in pressure-treated wood?

Pressure-treated lumber is ideal for outdoor projects due to its resistance to rot and insects. However, it is crucial to use materials specifically designed for treated wood, such as galvanized nails. Standard steel nails can rust and corrode due to moisture exposure and chemicals in pressure-treated lumber. Galvanization, the process of coating the metal with zinc, protects nails from corrosion and enhances their durability. It prevents staining or discoloration of treated wood and leaves behind unsightly marks even in wet conditions.

Ring shank nails are another important factor to consider for pole barn construction. These nails have a textured edge that firmly grips into wood, making them suitable for floors, walls, and other lumber that needs to withstand movement and wind forces. They provide 288 greater pull-out resistance than smooth shank nails, ensuring your project remains secure over time.

What should never be done with pressure-treated wood?

Pressure-treated wood should not be used for food containers or cutting boards, and even playsets should be protected with a sealant. Workers should wear gloves, protective clothing, respirators, and goggles when working with pressure-treated wood. Wash clothes exposed to treated lumber separately and avoid burning it. Applying an oil-based primer and protective sealant can limit pesticide exposure from skin contact, dust, or rain, using sealants labeled as safe for pressure-treated lumber.

What fasteners to use with pressure-treated wood?

For your next project, choose hot-dipped galvanized zinc, stainless steel, or a proprietary connector line for pressure-treated lumber. These fasteners ensure longevity and protect against corrosion. Keep pull-out strength in mind, as the length and width of the fastener, along with the lumber’s thickness, can impact tensile strength, potentially causing the project to fail if not calculated correctly. If you’re unsure about the best fasteners, consult with the SFS team at 610-376-5751.
