Why is wood drying crucial for your deck or patio?
For your outdoor living space in Quebec, whether it's a natural wood deck or a composite deck, the wood's moisture content plays a decisive role in the durability and stability of your installation. Improperly dried wood can quickly become the source of cracks, warping, and premature deterioration.
Understanding Wood Moisture
Most planks intended for deck construction are sold "wet," with a moisture content exceeding 30% of their water weight. This saturated wood not only makes it harder to work with, but it also undergoes significant shrinkage as it dries.
Consequences of Wet Wood
As wood loses water, it contracts in all dimensions, but it's mainly the shrinkage in width and thickness that causes structural problems:
- Warping: deformation of planks, making the surface uneven.
- Splitting: appearance of cracks on the surface and deep within.
- Rotting: favorable environment for fungi and bacteria responsible for decomposition.
- Infestation: attraction of wood-boring insects to damp wood.
"Properly dried wood is the first step towards a solid deck, free from cracks and mold." - Construction Expert, Magasin de Patio
Methods for Drying Wood Before Installation
If you opt for "green" or "wet" wood, several methods can effectively reduce its moisture:
- Air Drying: stack your planks on spacers in a shaded, dry, and well-ventilated area to ensure uniform air circulation.
- Kiln Dried Wood: purchase lumber treated at the sawmill, ready for use, while anticipating a higher investment.
- Regular Monitoring: use a moisture meter or make a cross-cut to inspect the heart of the wood and check the moisture content.
How to Measure Wood Moisture
To ensure a successful installation, the use of a wood moisture meter is recommended. You can also request this service directly from your building materials dealer. A measurement below 20% is generally considered acceptable.
Wood Shrinkage and Its Dimensional Impacts
Wood shrinks in length, width, and thickness as it dries. While length remains relatively stable, changes in width and thickness cause the main problems: bowed planks, uneven surfaces, and loosened joints.
Advantages of a Composite Deck
To forever avoid the hazards associated with wood moisture, composite decks offer a reliable and durable solution. Premium brands like Fiberon, TimberTech, Trex, and TruNorth offer planks resistant to water, insects, and fungi, without requiring prior drying.
- Dimensional Stability: no shrinkage, no warping.
- Minimal Maintenance: a simple annual cleaning is sufficient.
- Varied Aesthetics: wide selection of colors and finishes (e.g., Beachwood, Walnut).
Choose peace of mind with composite
By choosing a composite deck for your deck in Quebec, you are investing in long-term performance and aesthetics. Say goodbye to the costs and efforts associated with wood drying while enjoying a welcoming and durable outdoor space.
