Trim with Denali Cedar
Trim defines your house and increases its value. Denali Cedar is ideal for exterior trim. As a species, Alaskan yellow cedar is renowned for its decay resistance and stability; it will outmatch any other. Use Denali Cedar for all trim and architectural details: cornerboards, fascia, soffit, freize board, casings, boxed post-and-beam.
Manage the Application
Key to all trim applications are well-documented techniques to manage moisture away from the building.
- 1. Use a drip edge at the roof and fascia intersection.
- 2. Install Z-flashing at window and door casings.
- 3. Do not apply trim directly to sheathing; create an air space.
- 4. Apply breathable rainscreen housewrap or firring strips behind the trim.
- 5. Never apply dry trim over wet material. Do not fasten directly on pressure-treated products. (see #4)
- 6. Avoid miter joints on exterior trim.
TIP: Make sure all vertical trim runs past intersecting horizontal trim to direct water flow downwards.
Prep for Paint
90% of house trim is painted. Ask your builder to have your trim pre-primed prior to delivery, even if you have not settled on topcoat color. A professional pre-primer will coat all sides evenly in a controlled environment. When you are ready for the final topcoat to be applied on site, make sure moisture readings of the trim are within the correct range. Your builder should have a moisture meter.
TIP: Insist that your builder prime the fresh cut ends as he cuts lengths to size. This keeps moisture from wicking into your trim.
