Whether you are a hobbyist making a gorgeous table or a professional getting lumber ready for construction, the seasoning process is everything for everyone who deals with wood. Seasoning is just the regulated drying of wood; it lets the moisture content gradually drop until it reaches a stable, workable level.
Almost every time, hurrying this procedure results in calamity warping, cracking, and checking that might destroy a perfect piece of wood. Success comes from knowing how to live with nature, not from opulent, costly gear. The simple breathable tarpaulin is among the most effective but sometimes misinterpreted instruments for this.
Many individuals believe erroneously that covering wood fully in plastic sheeting is the best way to shield it from rain. This is a recipe for ruined lumber, mildew, and mold. Wood needs to breathe. It needs a cover that keeps it safe from rain, snow, and strong sunlight while yet letting the moisture stuck inside the boards to evaporate out into the air. This is the point at which the appropriate type of cover turns into your best friend in the garden.
The Advantage of Going Green
At your neighborhood hardware store, the Green Tarpaulin might have caught your eye in particular. Though not always, these green tarps are frequently made from woven or laminated polyethylene fabric to be permeable. The well-known green tint now stands for a mid-weight, multi-use tarp fit for many outdoor uses, including wood seasoning.
Choosing a Green Tarpaulin for this use necessitates verifying the label or product description for the term breathable. For long-seasoning applications, a breathable Green Tarpaulin provides an excellent compromise between durability, weather resistance, and the required vapor permeability. Its hue also somewhat improves its ability to fit into a yard or garden environment when compared to a brilliant blue option.
Why Your Current Cover Might Be Hurting Your Wood
Should you ever have discovered a stack of wood only to find a moldy smell and a hazy layer of blue or green mold, you have felt the effects of a non-breathable barrier. A sealed atmosphere is produced by solid plastic sheets, similar to those employed for some low-cost tarps or painting drop cloths.
The sun heats the air under the plastic when it shines, which draws moisture from the wood. But with nowhere to go, that moisture gathers on the bottom of the plastic, forming a tiny rainforest right on your wood. Fungal growth and decay thrive in this continual cycle of wetting and drying mixed with a lack of fresh air.
This trapped moisture also slows the uniform drying of the wood. Though the outside may appear dry, the inside stays a sauna, which causes great internal tensions. Those strains relax when you ultimately go to utilize that wood, and the wood bends and cracks in such a way that it is useless for fine work. Seasoning's aim is a gradual, consistent, even lowering of moisture across the whole board. The cover you choose should be a collaborator in the process rather than a roadblock if you want to reach this.
The Superior Choice: Breathable Tarpaulin Explained
What then constitutes the other choice? Breathable tarpaulin is the response. Unlike hard plastic, these tarps let water vapor flow through while yet repelling liquid water. They are composed of substances that let water vapor pass through. Consider it as a hi-tech rain jacket for your wood. It stops the rain from seeping in, but it allows the perspiration (the moisture from the wood) to evaporate out. Under the tarp, this provides a steady microclimate where the wood can dry naturally and safely yet is protected from direct exposure to the elements.

This is where the original Canvas Tarpaulin really excels. For ages, canvas has been the preferred choice for safeguarding priceless items; with good cause. Constructed of cotton or a cotton-polyester mix, it is inherently breathable because of its closely woven yet naturally fibrous texture. It effectively sheds rain while allowing a continuous airflow that moves moisture away from the wood. Good canvas tarps offer excellent protection without plastic's condensation issues; they are strong, heavy enough to stay put in the breeze, and long-lasting.
Setting Up Your Seasoning Station for Success
Half the battle is having the correct cover; how you utilize it counts just as much. Good stacking and covering method will determine the distinction between ideally seasoned wood and a disappointing stack of firewood.
First, your wood has to be stacked properly. Stack your lumber always on a robust, elevated base. Use pressure-treated lumber rails or concrete blocks to keep the wood at least six inches from the ground. This lets air circulate underneath and stops ground moisture from seeping up into your stack. Use tiny, dry strips of wood, roughly ¾ inch thick and an inch wide, between each layer of boards. Arrange these stickers straight up every 16 to 24 inches along the boards' length. These stickers form vital air pathways that go across the whole stack, enabling moisture to escape from all sides of every board.
The Art of Draping, Not Sealing
Now regarding the tarp itself. Wrapping the timber pile like a gift is the worst error. You want not to build a sealed tent. The aim is to design a roof that hangs above the stack to shield it from direct sunshine and rain while allowing optimal airflow on the sides.
Like a roof, spread your breathable tarpaulin over the stack's top. To safeguard the wood from driving rain and sun, it should extend at least a good foot or more over the edges and ends. Above all, do not let the stack's sides be covered by the tarp. The main route for moisture to escape the board is at the ends of the wood where the grain is exposed. One of the worst things you can do is cover these ends with a non-breathable material, since it traps moisture inside. Allow the wind to move freely through the stickers and across the edges of the boards. Though you should not pull it too tight to limit airflow, weigh down the tarp's edges with stones or wood.
Long-Term Management and Patience
Seasoning wood calls on great patience. For many hardwoods, at least one year per inch of thickness is needed for adequate air-drying. Your role right now is to be a guardian, not a continuous meddler. Check on your stack from time to time, especially after a strong storm, to make sure the tarp hasn't blown off or drooped and formed a pool of water.
It's wise to conduct a more thorough check every few months. Feel the wood; it should be chilly and dry, never moist or cold. Seek for any evidence of insect or mold activity. If you notice the first signs of mould, it means the airflow is not enough. Opening the sides more could require you to add extra stickers or change the tarp. Recall the surroundings beneath the tarp should resemble a shady, breezy patio rather than a wet cellar.
Why This Method Pays Off in the Long Run
While a thin plastic sheet would cost a little less initially than a strong, breathable Canvas Tarpaulin or a dependable breathable Green Tarpaulin, the return is great. You're guarding possibly thousands or even hundreds of dollars worth of timber. This approach of seasoning your wood will keep it flat, strong, and free of mold. It will be a pleasure to work with once you finally get it into your studio. Once you have planned it, it won't distort. Once your project is finished, it won't crack. You will produce expert, long-lasting work from regular, predictable material.
Adopting a slow and steady attitude means using a permeable cover. It's about using the natural qualities of wood and the environment instead of fighting against them. Giving shelter while allowing breathability, you provide the perfect environment for nature to work gently and efficiently. Therefore, for your following pile of green lumber, forgo the plastic shroud. Give your wood air and protection as a gift. Cover it with a dependable, breathable tarpaulin, stand back, and watch time produce your ideal fabric.
