How to Install Board and Batten Siding

Tags: Siding

Board and Batten siding is a classic siding option known for its old-time look and durability. Originally used as siding for barns and outbuildings, Board and Batten has been around for decades, and for good reason. At Marks Lumber, our circle sawn Board and Batten siding is perfect for those looking to recreate this beautiful, rustic look.

The key to this siding, along with any other wood siding, is proper installation. While the look of Board and Batten is still the same as all those years ago, nowadays, we recommend a few more steps than just nailing up the boards. At Marks Lumber in Clancy, Montana, we recommend following the Western Wood Products Association (WWPA) guidelines for installation and finishing our wood sidings.

Step 1: Acclimation

Proper acclimation of wood products is critical to quality installation. Stacking siding material with space between them for a minimum of ten days is recommended for dried Marks Lumber products.

Step 2: Pre-finish

Finishing is one of the most important steps in the installation process. In dry climates, like we have in Montana, pre-finishing is advised. This means both sides, edges, and all cut ends should be pre-finished or primed. Make sure your pre-finish is compatible with the final finish products. At Marks Lumber, we recommend using Lifetime Wood Treatment for an easy, low-maintenance finish product.

If you choose a water-based finish, keep in mind that it can add significant moisture to the boards, which can lead to swelling. Make sure you allow time for the siding to re-dry and acclimate after pre-finish and before installation.

Step 3: Installation

Natural wood siding should be installed over a weather-resistive barrier for all sheathing materials. If sheathing or the weather-resistive barrier gets wet prior to installation, allow the surface to dry before starting.

Board and Batten siding can only be installed vertically. The siding should be nailed to horizontal blocking, not exceeding 32 inches on center. To join pieces of siding, cut a bevel on the ends of both pieces of material to be joined (scarf joint).

The wide boards used in Board and Batten benefit from having backing material behind them. Use caution when driving fasteners on wide pieces, especially if no backing is used.


When it comes to natural wood siding, maintenance is critical. Most natural wood sidings benefit from regular washings. A light-pressure power wash with Perma-Chink System’s Log Wash will remove dust and harmful pollen and help keep your siding protected.

Note: Wood never dies; it is going to swell, shrink and move with changes in temperature and humidity over its life. Good installation techniques have been developed to take this absolute fact into account.

To ensure the lasting beauty of Marks Lumber sidings, proper installation is critical. Looking for a durable, unique wood siding that you can install yourself?
