Sheathing the walls with plasterboard in a wooden house: several secrets of high-quality repairs

Plasterboard sheathing is a common option for many homeowners who want to create a smooth, contemporary finish on their wooden house walls. This project has the potential to greatly improve the interior, making it cozier and more aesthetically pleasing. But working with wood has its own set of difficulties that call for close attention to detail.

Temperature and humidity variations cause wooden structures to expand and contract, which can result in uneven surfaces or cracks if the plasterboard isn’t put in properly. It’s critical to adhere to particular methods and techniques intended for wooden homes in order to prevent these problems. These tips can help you achieve a long-lasting, high-quality outcome whether you’re doing the work yourself or hiring an expert.

In order to successfully sheathe the walls of your wooden house with plasterboard and achieve a flawless finish that accentuates the natural beauty of wood, this article will walk you through some of the most important tips and tricks.

Features of repairs in a wooden house

It is wise to think about this option ahead of time because the house’s wooden walls have the potential to dry out and distort over time.

What challenges might we encounter while fixing a wooden house? This is, first and foremost, the walls’ inevitable seasonal deformation. Since wood can change slightly in shape in response to changes in temperature or humidity, this factor must always be considered.

This characteristic makes the adhesive installation method—which is thought to be the easiest when dealing with drywall in brick buildings—totally inappropriate for us. Since there is no space for deformation when plasterboard is fastened tightly, it will eventually break because the plasterboard sheet will bend with the walls.

Plasterboard installation on wooden walls is distinct from one another for more reasons than just deformation. An equally important factor is the increased surface humidity, which can cause mold spores to form and quickly grow under the finish, posing a serious health risk in addition to destroying the plasterboard.

In a wooden house, plasterboard sheathing provides a smooth, long-lasting surface for finishing; however, in order to preserve the wood’s inherent movement and avoid future problems, careful preparation is needed. This article contains helpful advice on how to ensure a high-quality repair, such as how to choose the right materials to create a perfect and long-lasting finish, account for wood expansion, and correctly attach the plasterboard.

Frameless installation

Plasterboard cannot be glued to wooden walls, as we have stated. However, this does not imply that installing it without creating a sheathing is unfeasible. It is feasible, but we will use plastic-sleeved dowels as a fastener. These dowels are simply driven into the wall and expand within, which causes the fastening to occur.

Many people are particularly happy with this method’s affordability, and it’s very simple. Ultimately, in this instance, you won’t have to pay for the frame’s materials or labor costs. Unfortunately, this method’s applicability isn’t always guaranteed because of several limitations. There are several restrictions, but we’ll concentrate on the most important ones.

Limitations

• If your wall freezes in winter, then this method of fastening will not work. The wall will get even wetter. And even moisture-resistant plasterboard will not cope with such high humidity.
• If large communications run along your wall, such as heating pipes, water pipes or ventilation systems, then they will either have to be redone and moved away from the wall, or another installation method will have to be considered.
• The curvature of the walls exceeds 2 centimeters. In this case, the surface will have to be leveled, but it is much easier to abandon this installation method.

As you can see, there are several circumstances in which plasterboard applied without a frame cannot be used to cover wooden walls. And for that reason, despite being the simplest, this approach is not thought to be the most popular.

Consider yourself fortunate if you haven’t found a single item on the list in your house. In this instance, you can utilize this option, so let’s take a closer look at the procedure.

Counseling! Make sure you choose a high-quality plasterboard. Special sheets bearing the GKLVO marking are on sale right now. This is stronger, non-flammable plasterboard that resists moisture. Although there won’t be much of a price difference, these walls will endure much longer.

Installation

The first step in sheathing wooden walls with plasterboard that isn’t framed is meticulous surface preparation. In our case, it will determine how well the entire repair turns out.

Thus, there are multiple stages to the installation:

1. Remove the old finish and clean the surface from dust, dirt and grease stains.
2. Prime the walls with impregnations with antiseptics that prevent the appearance of mold and mildew (see. Primer for wood and the rules for choosing it).
3. Let the wood dry and apply another layer of primer. The more there are, the better. There is no place for savings.
4. Cut the sheets to size, taking into account small gaps at the bottom and top. 3-5 millimeters are enough. They are necessary to compensate for possible deformations of the walls, then the drywall will have free space for curvature and it will not burst.

1. Put wedges on the floor for the gap, and lean the drywall sheet against it, starting from a corner convenient for you.
2. Drill a hole in the center of the sheet and hammer a dowel into it until it stops.
3. We drill new holes horizontally and vertically in all directions with a step of about 30 centimeters. Also, we hammer in fasteners along the perimeter of the sheet.
4. We check the sheet for installation strength and if a weak spot is found, we make additional reinforcements.

That’s essentially it; we install the remaining sheets in the same manner, and we use putty and a specific type of reinforcing mesh to seal the joints between them at the end (see. How to use putty on plasterboard joints (technologically).

Crucial! Carefully hammer in the dowels. Over time, these fasteners will simply stop holding the sheet; one more blow will cause the dowel head to break through the cardboard layer, necessitating a redo.

Frame installation

Using this method, a special sheathing is built on the walls of a wooden house before the walls are sheathed with plasterboard. This serves as the foundation for fastening the sheets.

In this case, a wooden beam would be the best choice for constructing a frame (see. Plasterboard frames can be installed on walls by hand, though experts try not to use them in situations involving brick walls. The point is that wood is more brittle and prone to deformation than metal, but since wood is used to build walls, there is no need to prolong the lathing’s useful life.

In this case, it’s crucial to adequately protect the wood; a water-based stain or specific impregnation will work well. They won’t greatly increase the bar’s lifespan, but they also won’t let bugs grow there, which would sharpen and eventually ruin the wood.

Another option is to decline to use metal plumb lines. Long black screws make it much easier to secure the bar, and varying-sized wooden wedges can be used to account for wall irregularities.

Installation

Consequently, we mark the wall initially. In order to prevent the sheet from sagging or breaking in these areas, it is crucial that the space between the guides not be greater than 50 centimeters. Although installing horizontal guides is preferred, it’s not required; you can live without them.

Following the application of the markings, we align the first block with the wall and use a screwdriver and a self-tapping screw to secure it, following the building level readings. We immediately observe that a discrepancy of 2-3 millimeters is negligible and can be disregarded; however, larger discrepancies are eliminated by putting wedges beneath the block.

Crucial! Wooden self-tapping screws have a broad thread pitch. Over time, they do not fly out and they press the material much better.

As you can see, it’s not a difficult process to arrange a frame from a wooden beam. However, to gain a better understanding, we suggest watching the video in this article.

In a wooden house, plasterboard is a great way to achieve a smooth, contemporary finish without sacrificing the wood structure’s inherent charm. When applied properly, this technique can greatly improve the interior, increasing both the functional and visual appeal of the area.

It is crucial to pay attention to the details in order to guarantee a high-quality outcome. Important procedures that affect the walls’ longevity and appearance include properly fastening the plasterboard, permitting natural wood movement, and meticulously finishing the joints. These minor yet significant details can have a significant impact on the result.

In the end, sheathing the walls with plasterboard can turn a wooden house into a comfortable and fashionable one with the appropriate methods and approach. This approach is a useful and efficient way to finish a new space or to update an old one.
