How to Hang Drywall on an Uneven Horizontal Plank Wall
When working with an uneven horizontal plank wall, the process of hanging drywall can seem daunting. However, by utilizing the right tools and techniques, you can achieve a flawless finish. This guide will walk you through the necessary steps to create a smooth and level surface, ensuring your drywall installation is both professional and visually appealing.
Preparing the Surface: Planing and Shimming
The first step in addressing an uneven horizontal plank wall is to create a level surface. One effective method is to use a powered hand planer to remove the highest spots on the wall, which will help to bring the overall surface to a uniform level. It's crucial to check for any nails or protruding screws before using the planer, as it could damage the adjoining studs.
Once you have planed down the high spots, the next step is to address the low areas. This can be achieved by adding drywall shims to these low spots, effectively raising them to the same level as the rest of the wall. Drywall shims are specifically designed for this purpose. Typically made of thick cardboard, they are approximately 1/20th inch thick, 1.5 inches wide, and 45 inches long.
Drywall Shims: A Detailed Guide
Drywall shims are essential tools in any drywall installer's arsenal. They are used to correct framing flaws and to provide a flat surface on uneven surfaces. The ideal spacing for these shims is typically 16 inches on center to ensure a consistent and sturdy support. Shimming the lath (if present) out to a flat wall is another technique that can be employed.
To properly install the shims, position them along the wall and secure them with staples or brads. Utilize a 6-foot or longer straightedge to ensure that the new surface is perfectly flat. This step is critical, as it will determine the overall quality of your drywall installation.
Advanced Techniques for a Flawless Finish
In cases where a significant amount of shimming is required, consider installing vertical 1x2 strapping with shims to create a perfectly flat wall. By finding the high point with a straightedge and possibly sanding it down with a coarse belt sander, you can achieve a consistent and level surface. Once this is done, make sure the wall is both flat and plumb before proceeding with the drywall installation.
It's also beneficial to use a laser pointer, a spot light, or a flashlight to identify the high spots accurately. Once you have pinpointed the highest point, use a level to shim up all the low spots, ensuring they reach the same level as the highest point. This method will help you achieve precise and uniform results.
Conclusion
Improperly handling an uneven horizontal plank wall can lead to a subpar finish, but by following the techniques outlined in this guide, you can achieve a professional and visually appealing result. Whether you choose to use a hand planer, drywall shims, vertical lath, or a combination of these methods, the key is to ensure that each step is executed with precision and attention to detail. With the right tools and a systematic approach, you'll be able to hang your drywall perfectly, even on an uneven surface.
