Everything you need to know about the wood in my cabin (marks, cracks, maintenance)

Wood is a natural, living material. It is therefore normal for it to change appearance over time or depending on climatic conditions. Here's how to distinguish between what is normal and what requires maintenance.

1. I have green marks on the wood: is it mould ?
Don't worry, it's not mould !

• The explanation : these green (or sometimes whitish) marks are salt deposits caused by autoclave treatment. This is actually a sign of quality : it proves that the wood has been deeply impregnated to resist insects and rot.
• The solution : these marks are harmless and will disappear naturally over time and with exposure to the elements. If you want to reduce them immediately, light sanding is sufficient.

2. I have black marks or surface mould.
If you notice black or greyish spots, these are surface mould caused by ambient humidity or storage conditions.

• Is this serious ? No, this defect is superficial. It does not affect the strength of the wood or its structural integrity.
• How can I remove them ? Clean the area with a brush and a simple solution (a mixture of water and white vinegar, or a special wood cleaner).
• Leave to dry completely, then treat the wood with a protective product (wood stain or oil) to prevent moisture from returning.

3. The wood in my cabin is cracking
Have you noticed cracks or splits in the boards or posts ?

• This is a natural phenomenon : wood is a hygroscopic material, which means it expands and contracts depending on humidity and temperature.
• Safety first : although these cracks can sometimes look alarming, they do not compromise the strength or quality of your cabin. They do not run through the entire thickness of the wood and rarely grow larger over time.
• Exception : if a large crack appears directly at a fastening point (screw/bolt), please contact our after-sales service with a photo.

4. The colour of the wood changes (greying).
With exposure to UV rays (sun) and rain, all wood will eventually turn grey naturally. This is a normal aesthetic process. If you wish to preserve the original colour or stain your shed, we recommend applying a saturator or suitable wood stain once a year.
