Standard plywood is a highly porous material which easily gets wet and is susceptible to damage if exposed to water for too long.
When plywood gets wet, whether due to a leak, flooding, or excessive humidity, it becomes susceptible to various forms of damage.
Acting promptly to address wet plywood is crucial to prevent further deterioration and costly repairs.
How do you save and restore wet plywood?
The restoration process for wet plywood involves several steps designed to dry, clean, repair, and preserve the wood.
While minor water exposure can be addressed easily, significant water damage may require more extensive restoration efforts.
The key steps in the restoration process are as follows
Step 1: Assessing the extent of Damage
When dealing with wet plywood, the first step is to conduct a thorough assessment of the damage.
This evaluation will help you understand the severity of the water exposure and guide your restoration efforts accordingly.
For a complete assessment, do the following:
Extent of Water Penetration:
Check the affected area to determine how far the water has penetrated the plywood.
Water can seep into the wood through the edges or surface, and in more severe cases, it may have saturated the plywood’s core layers.
Understanding the depth of water penetration will help you gauge the level of damage and the required drying time.
Signs of Mold or Mildew:
Inspect the wet plywood for any visible signs of mold or mildew growth.
Mold appears as black, green, or brown patches, and mildew typically appears as white or gray powdery spots. If mold is present, it needs to be addressed promptly to prevent further spreading and potential health risks.
Indications of Rot or Decay:
Look for soft spots or areas that appear discolored, as these can indicate rot or decay.
Wet plywood is highly susceptible to fungal attacks, which can lead to the breakdown of wood fibers and severely compromise the plywood’s structural integrity.
Condition of the Wood:
Check the overall condition of the wet plywood. Determine if it’s still structurally sound or if it has started to warp, buckle, or delaminate. Assessing the condition of the wood will help you decide if restoration is feasible or if replacement is necessary.
Location and Type of Water Exposure:
Consider the source of water exposure.
Whether it was from clean water, such as a burst pipe or rainwater, or contaminated water, like sewage or floodwater, will impact the restoration process.
Contaminated water poses additional health risks and requires special precautions during restoration.
Duration of Exposure:
Evaluate how long the plywood has been exposed to water.
The longer the exposure, the higher the chances of severe damage. Quick action is essential to prevent further deterioration and mold growth.

Step 2: Drying the Wet Plywood
a.)Removing Excess Water:
The first step in the drying process is to remove as much excess water from the wet plywood as possible.
The faster you can remove standing water or excess moisture, the more effective the overall drying process will be.
Here are some methods to dry wet plywood:
Absorbent Materials:
Use absorbent materials like towels, sponges, or rags to soak up water from the surface of the plywood. Press down firmly to maximize water absorption.
Wet/Dry Vacuum:
If there is a large amount of water, a wet/dry vacuum can be helpful in sucking up the water from the plywood surface and grooves.
Elevate the Plywood:
Lift the wet plywood off the ground or surface it was resting on to allow air circulation beneath it. This will aid in drying both sides of the wood.
B. Utilizing Fans and Dehumidifiers:
After removing the excess water, the next step is to accelerate the drying process using fans and dehumidifiers.
Proper air circulation and moisture removal are essential for effective drying. Here’s how to use fans and dehumidifiers efficiently:
- Set up large fans around the wet plywood, ensuring they blow air directly over the surface. Position them strategically to create cross-ventilation, maximizing air circulation.
- Use dehumidifiers in the vicinity of the wet plywood to extract excess moisture from the air.
- Dehumidifiers help reduce humidity levels, which aids in drying the wood faster and prevents mold growth.
- Check the progress of drying regularly and adjust the positioning of fans and dehumidifiers if necessary.
- Monitor the moisture levels to assess the effectiveness of the drying process.
C. Applying Natural Airflow Methods:
In addition to fans and dehumidifiers, you can take advantage of natural airflow methods to aid in drying the wet plywood. Here are some natural techniques to consider:
- If the weather permits, consider moving the wet plywood outdoors to benefit from the natural airflow and the sun’s heat.
- Choose a shaded area to avoid direct exposure to intense sunlight, which may cause the wood to warp.
- Open windows and doors to promote cross-ventilation. This allows fresh air to circulate inside the space and expedite the drying process.
- If possible, place fans in open windows to draw fresh air into the room and push moist air outside.
- Utilize any available breeze or create airflow by setting up fans strategically to mimic natural wind patterns.
Step 3: Sanitizing and Cleaning
A). Using a Mixture of Water and Vinegar or Mild Detergent:
Sanitizing the wet plywood is important to remove any lingering bacteria, mold, or mildew.
One of the most effective and eco-friendly cleaning solutions is a mixture of water and vinegar or a mild detergent.
Here’s how to proceed with this step:
- Mix equal parts of water and white vinegar in a spray bottle or a bucket.
- Alternatively, you can use a mild detergent diluted with water as per the manufacturer’s instructions.
- Spray or apply the water-vinegar or detergent solution generously over the entire surface of the wet plywood.
- Ensure that the solution reaches all the nooks and corners where mold and bacteria might be present.
- Allow the solution to sit on the plywood for a few minutes to break down and loosen any mold or mildew.
B. Scrubbing Away Mold and Mildew:
After allowing the cleaning solution to sit for a few minutes, use a scrub brush or sponge to gently scrub away the mold and mildew from the plywood surface.
Here’s how to do it effectively:
- Use a soft-bristled scrub brush or a sponge to avoid damaging the plywood surface.
- Apply light pressure while scrubbing to remove the mold and mildew without causing any harm to the wood.
- Concentrate on areas where mold and mildew are visibly present or where you suspect their growth.
- Frequently rinse the scrub brush or sponge in clean water to prevent spreading mold spores to other parts of the plywood.
C. Rinsing and Drying the Plywood:
Once you have scrubbed away the mold and mildew, it’s crucial to rinse off any residue from the cleaning solution.
Follow these steps to ensure a thorough rinse and proper drying:
- Using a clean sponge or cloth, rinse the plywood surface with clean water. This will remove any remaining cleaning solution and loosened mold debris.
- Wipe the plywood surface with a dry cloth or towel to remove excess water.
- Allow the plywood to air-dry completely. You can use fans or dehumidifiers to expedite the drying process.
It’s important to note that mold and mildew can pose health risks, so it’s essential to wear appropriate protective gear, such as gloves and a mask, while cleaning the wet plywood.
Additionally, ensure proper ventilation during the cleaning process to avoid inhaling fumes from the cleaning solution.
