The Ultimate Guide to Waterproof Plywood

When it comes to construction and woodworking projects, finding the right material is essential to ensuring durability and longevity. This is why waterproof plywood is highly preferred. In this ultimate guide, we’ll dive deep into what waterproof plywood is, its advantages, uses, and how to choose the best one.

Let’s get started, shall we?

What is Waterproof Ply?

Waterproof plywood, also known as marine-grade plywood, is a treated type of plywood that can handle humidity, moisture, and immersion in water without degrading or losing structural integrity. It is made using high-quality wood veneers and adhesive that is bonded under pressure and heat to create a strong, waterproof material.

Top 5 Advantages of Waterproof Plywood

The top five advantages of using waterproof plywood are:

Water Resistance

The primary advantage of waterproof plywood is its exceptional resistance to water and moisture. This property prevents warping, swelling, and rotting. Hence, making it ideal for applications where exposure to moisture is common.

Durability

Waterproof plywood is crafted using high-quality materials and adhesives, ensuring exceptional durability. It can withstand harsh weather elements and has a longer lifespan than standard plywood.

Durability

This kind of plywood is incredibly versatile. You can use it for various applications, from outdoor furniture and cabinetry to boat building and structural construction.

Eco-Friendly 

Another great advantage of opting for waterproof plywood over wood is that it is eco-friendly. You can easily recycle it at the end of its life to minimize waste.

Strength

Despite its water-resistant properties, waterproof plywood maintains its structural integrity even in wet conditions, making it suitable for load-bearing applications.

Understanding the Best Uses of Water-resistant Plywood

Waterproof materials, particularly waterproof plywood, have become essential components in designing and constructing kitchens and bathrooms. Here are the top uses of waterproof materials in kitchens and bathrooms:

Cabinetry

Waterproof ply is the ideal choice for kitchen cabinetry due to its resistance to moisture and potential water spills. It effectively prevents cabinets from swelling, rotting, or warping over time.

Countertops

Modular kitchens frequently use waterproof plywood to construct countertops to withstand the demands of daily kitchen use.

Vanity Units

Bathroom vanities are constantly exposed to water splashes from the sink. Waterproof plywood prevents damage, ensuring the vanity lasts longer without any signs of wear.

Shower and Bathtub Enclosures

They are used for lining shower and bathtub enclosures, providing a barrier against moisture and preventing water from seeping into walls and floors

Flooring

Waterproof materials, especially specialized plywood or backer boards, are often laid beneath bathroom tiles or vinyl flooring. This protects the subfloor from moisture damage and prevents mold growth.

How to Choose the Best Waterproof Ply for Your Home

Now that you know about the many benefits of water-resistant plywood, here is how to choose the best one for your space:

Plywood Thickness

The thickness of the plywood is a critical factor that affects its strength and suitability for different applications. Plywood thickness is typically measured in millimeters (mm) or inches. The number of layers, or “plies,” in plywood determines its thickness and strength.

Plywood starts with a minimum of 3 plies but can have more. For example, 3-ply plywood is 2 to 3 mm thick and is common for interior use. 5-ply, around 4 mm thick, is versatile for indoor and outdoor applications.

Multi-ply plywood, with seven or more layers, is the best choice for furniture and robust structures like roofing. So, consider the purpose/application to opt for the right thickness.

Plywood Grades

Plywood is categorized into various grades, each reflecting its quality and intended purpose. These grades are defined by their visual characteristics and structural suitability:

A-Grade: Reserved for applications where aesthetics are crucial, such as furniture and cabinetry, offering a near-flawless appearance.

B-Grade: Slightly less refined in appearance but still relatively smooth, commonly used for purposes like subflooring or wall sheathing.

C-Grade: May exhibit noticeable imperfections like knots, generally chosen for applications prioritizing functionality over appearance, such as structural framing.

D-Grade: The lowest grade, characterized by numerous flaws and irregularities, typically employed in temporary structures or situations where appearance is inconsequential.

Plywood Size

Plywood sheets come in standard sizes, typically 4 feet by 8 feet (4×8), although other dimensions are available. Consider the following when choosing the right size:

  • Project Dimensions: Ensure the plywood size fits your project’s dimensions without excessive waste. 
  • Transportation and Handling: Larger sheets can be challenging to maneuver, so choose sizes that are manageable for your workspace.
