What Makes Wood Rot?

Wood rot is caused by a combination of fungus, moisture, oxygen, temperature, and wood, which serves as a food source for the fungus. Among all of these causes, the one we can control is moisture, which fungi require.

Put, fungus requires moist wood to grow. That is why fungi will not grow on dry wood.

The fungus can enter the wood through contact or the air, as there is no such thing as airborne fungus.

When fungus grows on a piece of rotten wood, it has the potential to infect other, otherwise healthy wood. But now that we know how fungus grows, we can take steps to prevent wood from rotting.

Method 1: Select the Proper Wood for Ground Contact

The first step in preventing fence post rot is to select the proper type of wood.

Put, fungus requires moist wood to grow. That is why fungi will not grow on dry wood.

The fungus can enter the wood through contact or the air, as there is no such thing as airborne fungus.

When fungus grows on a piece of wood, it has the potential to infect other, otherwise healthy wood. But now that we know how fungus grows, we can take steps to keep the wood from rotting.

Cedar

This product contains a natural wood preservative that keeps termites, moths, and other insects at bay. In addition, its natural oils are so effective at killing fungi that people use cedar oil to treat acne and other skin blemishes.

Cedar’s natural oils also make it waterproof. The following are the most popular cedar varieties among builders:

• Red Cedar of the West
• The Yellow Cedar
• The Spanish Cedar
• White Cedar of the North.

Cedar is ideal for wooden railings, fences, and benches, among other things.

Redwood

Because the trunk of a redwood is mainly made of heartwood, it is naturally resistant to rot. Therefore, the inner core of the tree is referred to as heartwood. Extractives (compounds that fight fungi and protect the tree from insects) are found here.

Mahogany

Its strength, density, and toughness can withstand water and insects. As a result, it’s a popular material for doors and outdoor furniture.

These are the top types of wood that have a natural anti-rotting preservative. The issue is that their longevity and anti-rot properties translate into higher prices.

Alternatively, you can purchase pressure-treated wood.

Method 2: Make Use of Treated Wood

Pressure-treated lumber can still rot, but it lasts longer and is less expensive than lumber from heartwood and the tree above species.

Again, no pressure-treated lumber is impervious to rot. They are rot-resistant because they contain a liquid wood preservative but are not water-resistant. They can still be soaked and dehydrated. They will eventually develop cracks, twists, and bends, which is why you must understand How To Protect Pressure Treated Wood Underground.

It’s best to wear protective equipment (dust mask, goggles, and gloves) when working with this type of wood to avoid prolonged exposure to the chemicals used to treat it. Work either outside or inside.

CCA

Previously, wood was treated with chromate copper arsenate (CCA). CCA is an inorganic arsenic pesticide that protects wood from rot and pests. This was phased out in 2003 because the chemicals it contained (chromium and arsenic) were toxic to humans and could contaminate groundwater and soil.

Fortunately, non-toxic wood preservatives protect wood from decay and insects equally effectively.

Defect-resistant pressure-treated woods

Wood treated with Alkaline Copper Quat (ACQ)ACQ is a water-based wood preservative that repels insects and prevents rot. Nonetheless, treated lumber may crack, shrink, or warp.

When inhaled, in contact with skin, and inhaled, ACQ wood has very low to moderate toxicity. However, it may also cause minor irritation to the eyes. ACQ-treated wood is available in two colors: brown and green.

This material can be used for fences, decks, and utility posts. Indoors, it can be used for studs, beams, and frames. Ensure the wood does not come into contact with food, fish, or other living creatures in your aquarium.

Wood treated with copper naphthenate.

It’s becoming a popular material for outdoor projects. The Environmental Protection Agency has classified copper naphthenate preservative as a General Use pesticide. As a result, it not only prevents rot but also kills termites. It is less harmful to the environment.

The copper naphthenate preservative appears as bright green wood that gradually turns light brown. It also has a distinct odor that fades over time. When handling this treated lumber with its chemicals and odor, it is best to wear gloves and goggles.

Utility posts, docks, seeding trays, and greenhouses are all common uses for copper naphthenate preserved lumber.

Borate treatment

This type employs boric acid, a naturally occurring mineral combination that protects against rot and biological attack (termites, ants, roaches, and beetles).

This is used inside. Borate is commonly used to construct studs, sill plates, joists, plywood, and sheathing.

It is not recommended for use outside, especially in areas where water or rain can get in. Chemicals in the wood may be washed out onto the surface and then into the soil when soaked. It should not be used as a dining table material because it will come into contact with food.

Method 3: Soak your post’s bottom in a wood preservative.

Don’t worry if you didn’t buy any of the types mentioned above of wood, bought untreated wood, or have already completed your project. There are still ways to keep the wood from decaying underground.

What you’ll need is as follows:

Copper naphthenate is a wood preservative. First, check that it meets the standards of the American Wood Protection Association.

• A big bucket
• A paintbrush
• Googles
• Gloves
• Mask for the face

How to Apply a Wood Preservative

Make sure the untreated, fresh wood is dry before beginning the process. Then:

Step 1: Put on your safety gear.

Step 2: Measure out half a liter of preservative and pour it into a large bucket.

Step 3: Soak approximately 1 foot of the entire post or plank in water for 20 minutes.

Step 4: Apply the preservative to the entire surface of the wood.

Step 5: Let it dry for about an hour.

Step 6: Continue brushing additional coats (and allowing them to dry) until the wood no longer absorbs the preservative. Forget about the thick layer. Instead, make sure that the preservative has reached the heartwood.

Step 7: Let it dry naturally.

The wood should be painted.

The wood will stay dry if you paint it and seal it. To make the wood more durable, use latex paint.

Can pressure-treated wood, however, be painted? If you’re working with treated lumber, double-check to see if it’s possible.

Method 4: Make use of concrete and gravel.

Fence builders will tell you that there is a foolproof method for keeping fence posts from rotting.

Steps for adequately installing wooden fence posts

Step 1: Dig a hole twice the diameter of each fence post and up to a quarter of the total post length. These measurements ensure that the fence is secure, the posts are upright, and the fence posts do not rot. It is best to use a post-hole digger to ensure that your fence posts are the correct size.

Step 2: Add three inches of gravel and gravel dust to the hole. Make the gravel as tight as possible to keep your wooden posts from touching the soil. Furthermore, gravel allows water to drain quickly from fence posts.

Step 3: Insert the wooden post into the hole.

Step 4: Fill the entire hole with cement to the top. The wooden posts will be securely held in place by concrete. Make sure the cement fills the hole to the ground. If the cement is not packed tightly enough, unwanted moisture may enter, and the process may not prevent the fence posts from rotting.

Other wood treatments should be used.

Other antifungals and insecticides can be used in addition to copper naphthenate. Creosote and linseed oil are two examples. You must apply these every few years to protect your wooden fence posts or deck.

Tips for preventing rot on wooden posts

Whether you’re a first-time or seasoned wooden post owner, it’s critical to be proactive in rot prevention. Here are some pointers to help you keep your wooden posts in the ground, looking and performing at their best!

 Make sure water flows away from your fence post or deck plank.

Granted, a deck and a fence post are frequently wet, but is there a way for water to flow elsewhere and not become trapped underneath?

Under decks, you can place bricks or pour cement. The ground should have a slight incline to allow water to flow away from your house.

Keep each fence post and deck plank clean.

You do not want grass, dirt, dust, or mulch to build up on your deck or wooden fence posts. It is best to clean these regularly. You can use a power washer to make cleaning easier and ensure that all unwanted dirt is removed.

Make use of baking soda.

Its cleaning properties will deep clean your fence post.

Seal pressure-treated wood regularly.

This is done again to protect the wood from the effects of water, such as mildew growth, warping, and splitting.

Conclusion

You can become an expert in preventing wood rot in the ground by following these tips and techniques. What matters is that you understand the elements that cause wood to rot.

And how to prevent the elements above from accumulating and becoming stuck in the wood.

Keeping your deck or fence clean is critical to keep fungi at bay and moisture from settling on the wood. Take care of your project so that it rotates quickly.

FAQ on How To Prevent Wood From Rotting The Ground\

How is it possible to keep wood that is buried underground?

The best technique to preserve wood that will come into touch with the ground is to soak the portion of the wood that will be exposed to the ground for twenty minutes in a wood preservative solution. After that, apply a thick coat of the same wood preservative to the section of the wood that needs to be treated. Before you plant the wood in the ground, give it at least one night to dry out.

What prevents wood from becoming rotten?

Boric acid, often known as borate, is one of the fungicides that is considered to be among the most efficient in the treatment of wood rot. Either as a treatment to halt an active decay fungus from growing or as a preventative measure for future rot, it can be sprayed to wood while it is being constructed.

How can I prevent the wood from being damaged by the soil?

Wood preservatives rely heavily on biocides and insecticides, with permethrin being the most typical of these two classes of chemicals. In the class of chemicals known as pyrethroids, the insecticide known as permethrin can be found. Pyrethroids are man-made compounds that mimic the biological activity of naturally occurring extracts from chrysanthemum flowers.

What goes in the gap between the wood and the dirt?

You might want to consider painting or sealing the wood with a professional sealer. Because of this barrier, pollutants are prevented from leaking out of the wood and into the soil. Sealants can also reduce the amount of residues that are left on the skin after being handled by either an adult or a child.

How is it possible to stop things from rotting?

Keep moisture out

These fungi will eat their way through the wood, ultimately causing its decomposition from the inside out. Fungi are unable to grow on wood that has been allowed to dry out. In light of this, it is essential to ensure that the lumber on your deck remains as dry as is practicable. Sealing the deck with an appropriate coating is typically recommended as a preventative precaution.
