Acclimatize Siding Before Installing

One of the most stable softwoods, Western Red Cedar is nevertheless a natural material and it responds to the environment. Cedar siding can swell or shrink as it gains or loses moisture to reach equilibrium with the moisture content of the surrounding air. Ensuring that the moisture content of cedar siding is at equilibrium before it is installed will minimize movement later on.

On the job site, keep the wood dry. Stack siding off the ground and under cover. If the wood is to be stored over damp ground or new concrete, place a moisture barrier under the siding. Siding should be 4 to 6 inches above the ground with air circulating freely around and throughout the stack. Acclimatization time varies with the moisture content of the siding. The following procedures are suggested for different siding specifications.

Seal cuts Before Installing

All charred products come factory pre-finished and stained on 4 sides. The end cuts of the products should be touched up only with charred industries approved stain/sealer before the installation process. Also, any rips, cuts or notches should be similarly touched up only with charred industries approved stain/sealer before installation.


Use Hot-Dipped Galvanized, Aluminum or Stainless Steel Hot-dipped galvanized, aluminum and stainless steel nails are all corrosion-resistant and all can be used to nail Western Red Cedar. Other types of nails are not recommended. They can rust and disintegrate and react adversely with the natural preservative oils present in cedar resulting in stains and streaks. Copper nails also react with cedar and should not be used. Stainless steel nails are the best choice, for pre finished charred products.

Rain Screen Walls

Charred industries strongly recommends the installation of our products on a rain screen system. All rain screen walls should meet your local building code requirements. Our products perform great on rainscreen systems as the backside of our products comes pre-finished and allows any moisture that enters the rainscreen cavity to dry and not rot out the backside of your wood.
