When building a porch floor, it’s essential to coat all six sides of the wood. This practice is crucial for several reasons, including protecting the wood, enhancing durability, preventing moisture damage, and maintaining its appearance. Let’s break down these reasons to understand why this step is so important.
First, coating the wood provides a protective barrier against the elements. Wood is a natural material, and it can absorb moisture from rain, snow, or humidity. When wood gets wet, it can swell, warp, or even rot over time. By applying a sealant or finish all over the wood, you create a barrier that keeps moisture out. This protection is vital for the longevity of the porch floor, allowing it to withstand harsh weather conditions without degrading.

Second, coating all sides of the wood helps to prevent decay and insect damage. Wood is a favorite material for some pests, such as termites, carpenter ants, and other insects. These bugs can burrow into the wood, causing significant damage. If the wood isn’t properly coated, it becomes vulnerable and more likely to attract these unwanted guests. By coating the wood on all six sides, INCLUDING the ends (AFTER your cuts are made!), you create a barrier that deters insects and reduces the risk of decay. This is especially important for the parts of the wood that are buried in the ground or come into contact with moisture.
Third, coating the wood enhances its durability. A well-sealed porch floor can better withstand foot traffic, furniture, and other weight. Without a protective coating, wood can become scratched, dinged, or damaged more easily. Coatings like stains or sealers not only protect the surface from physical damage but also reduce the chances of warping or cracking. This means your porch will last longer and remain more attractive over time.

Coating helps to maintain the wood’s natural beauty. Many people choose beautiful hardwoods for their porch floors (such as Mahogany or IPE), and a good finish can enhance that beauty. When all six sides are coated, the color is richer, and the grain of the wood is highlighted. It also prevents fading from sunlight, which can cause the wood to lose its color over time. If the surface is left unprotected, UV rays can break down the fibers in the wood quicker than would normally occur, leading to a dull and lifeless appearance.
Additionally, coating the wood on all sides helps with the overall stability of the porch floor. When one side is sealed and the other is left bare, the exposed side absorbs moisture differently than the coated side. This uneven absorption can lead to warping or twisting. By coating all six sides, you ensure that the wood can expand and contract uniformly, maintaining its shape and preventing structural issues in your porch.

Another important reason to coat all sides is to help with maintenance. A properly coated porch floor is easier to clean and maintain. Dirt, spills, and stains are less likely to penetrate the wood when it is sealed, making cleaning a straightforward task. Regularly applying a maintenance coat of sealant helps prolong the life of the finish and keeps the floor looking fresh and new.
It is important to remember that investing the time and effort to coat all six sides of the wood is a small step that can lead to larger benefits. It may take a little more time upfront, but it helps to ensure your porch remains attractive and long-lasting. In contrast, neglecting this important step can lead to more significant problems down the line, including costly repairs or even a complete replacement MUCH sooner than you probably would prefer
