When properly installed, waterproof plywood can greatly enhance the performance and longevity of different types of furniture, floors and other construction projects. Despite the fact that waterproof plywood is intended to be waterproof, it can fail like any other type of plywood if it is not installed appropriately. By knowing what the most commonly made installation mistakes are, you can succeed at the installation and achieve long lasting durability.
Not Considering the Moisture Level Before Installation
One of the biggest mistakes is failing to consider what the moisture level is in the area where waterproof plywood is being installed. Even with solid plywood, it still will not hold up to extra moisture in the environment. If it is installed in an area that is wet already, the overall installation can be compromised over time. Always consider surface conditions prior to installation of waterproof plywood and make sure the surface is dry and has no moisture or standing water.
Not Preparing the Surface
Waterproof plywood must be laid on a flat surface and a clean surface to have the optimal adhesion and stability. Many installers do not take this step at all because they are trying to get on with the installation, but they end up laying a board that does not lay even as a result or has gaps throughout the surface of the ground board. Dust, grime, and rough patches can all affect the bonding and plywood will not be as durable. Always dry, clean, level and sand the surface before laying the waterproof plywood on top of it. The proper surface preparation will lessen the risk of warping, or even bulging due to long term stability issues.
Not Sealing the Edges Properly
Waterproof plywood may be able to withstand water and moisture as long as it is sealed; however, the edges of the board are still capable of absorbing water if the edges are not sealed. Another common mistake is to think that the top coat of waterproof plywood is sufficient to prevent the edge of the waterproof plywood board from bowing, expanding, or warping. The edge of the board will continue to absorb moisture over time even in conditions of high humidity like a kitchen, bathroom or outdoor furniture. Edge sealing with a high quality sealant will guarantee that puddles will not penetrate the edge and into the core of the board causing it to swell.
Using the Wrong Fasteners or Adhesives
Another common mistake is using the wrong fasteners or adhesive altogether. Typical fasteners like nails or non-waterproof adhesives will corrode, or the bonding will become compromised when subjected to water or humidity. If waterproof plywood is a necessity for your application, be sure to install it using stainless steel screws or a waterproof glue for joinery, to be able to remain secure over time. This minor detail will also help improve the longevity of your installation.
Conclusion
While waterproof plywood is an incredibly strong and durable building product, a successful installation will rely on precision and care. To ensure that waterproof plywood retains the proper quality over usable years, avoiding mistakes associated with the seal installation will facilitate long run characteristics of waterproof plywood. Considering these details, you will actually reap the incredible benefits waterproof plywood grants to an installation; you will have a strong solid product that looks good too.
