The Things You Need to Know About Alaskan Yellow Cedar

Many of you are interested in our Alaskan Yellow Cedar (AYC) and we are happy to give you good tips on exterior applications with AYC to make your project long-lasting.

The AYC is naturally found along the Pacific Northwest Coast and is plentiful in wet terrains that have poorly drained soils. It typically grows around 100-120 feet tall and can live up to 1,500 years. The AYC is a very valuable option for exterior applications because it has a high decay resistance and is resilient against most insect attacks.

All natural wood changes color. This is because of the chemical reaction between the wood molecules and its surrounding environment (i.e. sun, wind, rain, etc.). No matter what color you choose, it will change color due to the difference in ph levels between the wood and its surroundings. The browns will take longer to change color compared to the lighter and darker colors; however, they will still change color and tend to “silver” when exposed to the elements over a long period of time. Especially, if the structure is located in an area that has harsher seasons.

To help reduce the rapidness of this change, we recommend using the Lumber Seal by Tricopolymer Products-TrisealUSA, LLC (free of off-gasses, aka VOC-free) every 2-5 years when applying the cedar outdoors. We don’t recommend using anything with Polyurethanes because these types of sealants change the wood color drastically and faster.

Our last helpful tip for exterior applications is to acclimate your AYC wood in its environmental surroundings for 10-14 days before installing by laying them out in an area with good airflow. Doing this will minimize shrinkage, warping, checking, and splitting.
