Despite the poor quality, the local Home Depot manager only offered a store credit.
The CDX plywood brand mentioned is MacFarland.
Did You Know?
1. Although commonly used in construction, CDX plywood is typically not pressure treated. This type of plywood is typically made with an exterior glue that provides some resistance to moisture, but unless specifically labeled as pressure treated, it is not impregnated with chemicals to prevent decay or insect damage.
2. “CDX” actually refers to the grades of the plywood. The “C” stands for the face quality of the plywood, which can have some knots and defects, while the “D” represents the quality of the back face, which may have more imperfections. “X” simply implies that the glue used is exterior-grade and suitable for outdoor applications.
3. The term “pressure treated” refers to the process by which the plywood is impregnated with preservatives under high pressure. This treatment helps lengthen the lifespan of the wood by protecting it from rot, decay, and insect damage. However, this treatment is typically associated with other types of wood, such as lumber and decking boards, rather than plywood.
4. Despite its lack of pressure treatment, CDX plywood can still be used in areas exposed to occasional moisture, such as exterior sheathing, as long as it is properly sealed and maintained. It is important to regularly inspect and replace any damaged or deteriorated sections to prevent further water infiltration.
5. CDX plywood is often used as a base material for other types of finishing, such as vinyl siding or stucco. Its structural strength and water-resistant qualities make it an ideal choice for providing a stable foundation for these external finishes, contributing to the overall durability and longevity of the construction.
Author’s Experience With Cdx Plywood For Shed Floor
When it comes to constructing a shed or any other outdoor structure, selecting the right materials is crucial for its long-term durability. One such material often used for shed floors is CDX plywood, known for its affordability and versatility. However, my personal experience with CDX plywood for a shed floor left me with mixed feelings.
I opted for CDX plywood for my shed floor due to its reputation as a budget-friendly option. The initial installation went smoothly, and I was hopeful that the floor would serve its purpose effectively. However, it wasn’t long before I noticed some concerning issues.

When it comes to constructing a shed or any other outdoor structure, selecting the right materials is crucial for its long-term durability. One such material often used for shed floors is CDX plywood, known for its affordability and versatility.
However, my personal experience with CDX plywood for a shed floor left me with mixed feelings. I opted for CDX plywood for my shed floor due to its reputation as a budget-friendly option. The initial installation went smoothly, and I was hopeful that the floor would serve its purpose effectively. However, it wasn’t long before I noticed some concerning issues.
Suspected Cause Of Floor Buckling: 1/2 Inch Vs. 3/4 Inch Thickness
One factor that I suspected might contribute to the problems with the shed floor was the thickness of the CDX plywood used. The standard recommendation for shed floors is 3/4 inch thickness, but I had settled for 1/2 inch plywood to save costs. This decision seemingly proved to be an oversight, as the floor started to buckle, causing noticeable unevenness.
The lack of sufficient thickness in the CDX plywood may have compromised its ability to bear the weight and pressure applied to the shed floor. This concern led me to believe that using thicker plywood, adhering to the industry standards, would provide more stability and prevent future buckling issues.
Damage Section Patched With Cdx Plywood: Short-Lived Solution
To address the buckling issue and salvage the shed floor, I attempted to patch a damaged section with a smaller piece of CDX plywood. Initially, it seemed like a valid solution, and the patch appeared to hold up adequately. However, my hopes were once again shattered when I noticed the same section starting to curve within a week.
This experience raised doubts about the overall quality and durability of the CDX plywood I had chosen. It became evident that the patch was merely a temporary fix, emphasizing the need for a more long-lasting solution.
- The patch with a smaller piece of CDX plywood did not provide a permanent solution to the buckling issue.
- The CDX plywood’s quality and durability came into question after the patch failed to hold up adequately.
- A more long-lasting solution is necessary to address the buckling problem in the shed floor.
Cost Of Cdx Plywood: $25 For A 4′ By 8′ Sheet
One aspect of CDX plywood that initially appealed to me was its affordability. Each 4′ by 8′ sheet of CDX plywood cost me $25, which seemed reasonable given its widespread use and availability. However, the saying “you get what you pay for” proved true in this case. The initial savings on cost were overshadowed by the problems and repairs I had to undertake due to the plywood’s subpar quality.
- CDX plywood initially appeared affordable
- The sheets cost $25 each
- “You get what you pay for” proved true
- Problems and repairs were necessary due to subpar quality
Recommendations: Thicker Plywood And Higher Quality Brands
Based on my experience with CDX plywood for a shed floor, I strongly recommend opting for thicker plywood to ensure stability and avoid buckling issues. The standard 3/4 inch thickness is generally the safest choice for shed floors, providing the necessary strength to handle heavy loads and endure long-term use.
Additionally, considering the quality of the plywood is crucial. The brand I had used, MacFarland, proved disappointing in terms of delamination and overall durability. I encourage others to do thorough research and select a reliable brand or choose a higher quality grade of CDX plywood to prevent similar problems.
Ultimately, while CDX plywood may offer affordability, it is essential to consider the potential drawbacks. In situations where durability and longevity are paramount, investing in higher quality materials may be a more prudent choice.
- Opt for thicker plywood to ensure stability and avoid buckling issues
- Consider the quality of the plywood to prevent delamination and durability problems
- Thoroughly research reliable brands or choose a higher quality grade of CDX plywood for better results
- In situations where durability and longevity are important, investing in higher quality materials may be a more prudent choice.

Frequently Asked Questions
What is the difference between CDX and pressure-treated plywood?
The main difference between CDX and pressure-treated plywood lies in their durability and protective requirements. Pressure-treated plywood is designed to be long-lasting and can withstand the elements without the need for additional coatings or paint. On the other hand, CDX sheathing is a more affordable type of plywood that does not possess the same level of weather resistance. CDX sheathing must always be covered with bricks or shingles to protect it from moisture and other environmental factors.
Is CDX wood pressure-treated?
Yes, CDX wood is pressure-treated to help prevent fungal decay, rot, and termite infestation. This type of treated pine plywood is an excellent choice for constructing barns, playhouses, and sheds due to its enhanced durability and resistance to common wood hazards. The pressure treatment process ensures that CDX wood is fortified against these various threats, allowing for a longer lifespan and increased structural integrity of the constructed buildings.
Is CDX plywood good for outdoor use?
CDX plywood is indeed well-suited for outdoor use. Its widespread application in roof sheathing highlights its reliability in exterior settings. CDX plywood undergoes several treatments, enhancing its strength and water resistance. These qualities make it a favorable option for various exterior applications where durability and weather resistance are paramount.
What happens if CDX plywood gets wet?
When CDX plywood gets wet, it can result in water damage if the exposure is prolonged. While CDX plywood is designed to withstand some moisture exposure, exceeding the recommended limits can lead to warping, delamination, or decay. However, pressure-treated CDX plywood stands as an exception, as it is specially treated to resist moisture and can endure extreme conditions without suffering water damage.
