When it comes to selecting the right material for outdoor projects, durability and weather resistance are crucial factors to consider. In this article, we will explore the suitability of Baltic birch plywood for exterior applications. Baltic birch plywood is known for its strength and stability, but is it a viable option for outdoor use? Let’s dive into a test conducted by John Heisz, a well-known expert in woodworking and creator of the YouTube channel “Speakers and Audio Projects”.
In the video, Heisz discovered a piece of Baltic birch plywood that had been exposed to the elements while being used as a square on his wood-burning grill project. The plywood had been left outdoors, subjected to rain and sunshine, and even had some mud on its back. He decided to bring it into his workshop to assess its condition and determine its feasibility for exterior projects.
To evaluate the plywood, Heisz first compares it to a piece of Baltic birch plywood from his scrap wood collection that had not been exposed to the outdoor elements. Placing them side by side on a table, he observes that the outdoor-exposed plywood appears slightly higher in height. However, there are no visible signs of delamination or blistering on the surface.
Upon touching the surface of the plywood, Heisz notes that it feels smooth without any noticeable damage. However, he detects a slight dip in the middle, suggesting that the edges may have absorbed more water than the center. By placing the plywood on a flat surface, the dip becomes more apparent.
Curious to see the extent of water penetration, Heisz decides to cut open the plywood. The cut reveals that water has indeed entered the plywood, but it has not significantly degraded its structural integrity. He cuts another section right down the middle to demonstrate that the water has penetrated as deep as it possibly can into the plywood.
Comparing the swollen area to the dry portion of the plywood, Heisz estimates that the swelling is approximately less than 1/16 of an inch or about a millimeter in metric units. This minimal swelling implies that Baltic birch plywood can withstand exposure to moisture without significant dimensional changes.
Based on the experiment conducted by John Heisz, it is evident that Baltic birch plywood can indeed be used for exterior projects. Its ability to resist water penetration and maintain structural stability, even after prolonged exposure to rain and moisture, makes it a suitable choice for outdoor applications.
Using Baltic birch plywood for exterior projects offers several advantages. Firstly, its strength and durability ensure that it can withstand the rigors of outdoor environments. Whether it’s building outdoor furniture, constructing sheds, or creating decorative elements for your garden, Baltic birch plywood can handle it all.
Additionally, Baltic birch plywood has an attractive appearance. Its smooth surface and uniform layers provide an aesthetic appeal that can enhance the overall look of your outdoor projects. Furthermore, it is relatively easy to work with, allowing for precise cuts and smooth finishes.
To ensure the longevity of Baltic birch plywood in outdoor applications, it is essential to take proper care and apply appropriate finishes or sealants. Applying a waterproof coating or using an exterior-grade adhesive during construction will further enhance its moisture resistance.
In conclusion, Baltic birch plywood proves to be a viable option for exterior projects. Its ability to withstand moisture and maintain its structural integrity, as demonstrated in the test conducted by John Heisz, makes it a reliable choice for outdoor applications. When combined with proper care and finishes, Baltic birch plywood can provide long-lasting durability and aesthetic appeal to your outdoor creations. So, if you’re considering using plywood for your next exterior project, give Baltic birch plywood a try and enjoy its numerous benefits.
