Why You Shouldn’t Worry About Them
You should know that lumber is never dried in a kiln. It is left to air dry slowly for many years. Since wood is a natural and living matter, it will react to the weather conditions such as temperature variations and humidity and splitting may occur. Cracks and splits are created by humidity leaving the wood.
This phenomenon is absolutely normal and will not affect the sturdiness of the structure. Cracks and splits make the charm and authenticity of the wood and are part of its natural beauty.
Applying a finishing product such as oil or stain will protect the wood all while letting it breathe so the humidity can slowly be drawn out of it. We don’t recommend using a product that will seal the wood fiber and trap the humidity inside.
If a darker colour is applied to the wood, it may make the cracks more apparent. Using a fine brush to stain the inside of the crack will lessen the effect.
Applying a thin coat of stain after a few years will help hydrate the wood and will preserve its beauty. You should do so as soon as the colour has faded and is less vibrant.
