Shuttering plywood is high-quality waterproof plywood, especially used in creating concrete molds. However, improper handling or usage can compromise both the quality of your project and the lifespan of the plywood. Here are the 5 most common mistakes to avoid when working with shuttering plywood and tips on how to do it right.
- Choosing The Wrong Grade Plywood
Using low-grade or non-water-resistant plywood for heavy-duty or outdoor concrete applications is a common mistake. Such choices often lead to compromised durability, increased susceptibility to moisture damage, and a weakened final structure.
To avoid these issues, it is essential to select plywood that is graded for its intended use. Opting for BWP (Boiling waterproof) plywood is crucial for projects exposed to moisture or heavy loads. This type of plywood is designed to withstand harsh conditions and maintain its integrity over time.
- Neglecting To Apply Proper Coating
A common mistake is failing to apply release agents or waterproof coatings to the plywood before use. This oversight may cause the concrete to adhere to the plywood, resulting in damage to both the plywood and the concrete surface. These issues impact the quality of the final structure and reduce the lifespan of the plywood, leading to additional costs.
In order to avoid these problems, it is necessary to properly apply the right release agent before pouring concrete into the plywood. Oil- or wax-based products are commonly used as effective release agents, as they create a protective barrier that prevents adhesion.
- Improper Storage Practices
Storing plywood outdoors without adequate protection or stacking it in damp areas is a common mistake that can increase the warping, swelling, and weakening of the panels.
Exposure to moisture and humidity over time compromises the structural integrity of the plywood, making it unsuitable for construction purposes and leading to unnecessary expenses for replacements.
Maintaining the quality of shuttering plywood requires storing it in a dry, well-ventilated area. Using raised platforms can help prevent moisture absorption from the ground while covering the stack with a tarp adds an extra layer of protection against environmental factors
- Reusing Without Inspection
Reusing shuttering plywood is cost-effective, but it can compromise quality if not inspected thoroughly. It can cause defects such as cracks, delamination, or uneven surfaces. These issues can weaken the structural integrity of the plywood, and badly affect the concrete molding process and performance
It is important to inspect plywood after every use for safety and durability purposes. Replace any sheets that are beyond repair and address minor defects, such as cracks, by using appropriate sealants or adhesives
- Cutting Without Sealing The Edges
Cutting plywood to fit specific moulds is a standard practice in construction, but it often leaves the edges exposed to water and chemicals. If these edges are not properly sealed, they become vulnerable to water infiltration, which can lead to delamination and a loss of structural integrity.
To prevent such issues, it is crucial to seal the edges of the plywood immediately after cutting. Applying waterproof sealants or using edge bands provides a protective barrier that safeguards the plywood from moisture and chemical damage.
Final Thought
By avoiding these common mistakes, you can maximize the efficiency, durability, and cost-effectiveness of shuttering plywood in your construction projects. Proper handling, storage, and maintenance ensure that your plywood performs optimally and contributes to a high-quality finish.
