How to attach drywall to uneven or concrete walls with screws or glue: installation options, sheathing without a frame and installation of a profile with a support

Although drywall is a common option for wall finishing, working with uneven or concrete surfaces can make the process difficult. The appropriate method and supplies are needed to achieve a polished, polished appearance.

You can attach drywall using a variety of techniques, regardless of whether your wall is made of solid concrete or rough. Depending on the circumstances, you can either use glue or screws alone or in combination. Every technique has benefits of its own and can be customized to meet your unique requirements.

This post will discuss various installation methods, such as how to fasten drywall without a frame and how to use a profile with a support for a stronger hold. With these techniques under your belt, you’ll be able to paint any wall flawlessly.

Method	Description
Screws	Secure the drywall directly to the wall using screws, but ensure the wall is even or use shims to level.
Glue	Apply adhesive to the back of the drywall and press it against the wall. Suitable for flat or slightly uneven surfaces.
Sheathing without a frame	Directly attach drywall to the wall using screws or glue, often used when the wall is fairly even.
Installation with a profile support	Use metal or wooden profiles to create a frame, then attach the drywall to the frame, ideal for uneven walls.

Frameless drywall on the wall

Drywall leveling is the most common kind of repair work because it is quick and high-quality. Gypsum board can be fixed in two ways: framelessly and with a frame.

Installing frameless drywall on a wall is a quick and affordable solution with benefits. The techniques for attaching sheets with screws and adhering gypsum board to the surface are covered below.

When it is possible to level walls with frameless drywall

The gypsum board’s surface can be leveled using the following techniques:

• Frame – using profiles and accessories to create a lathing for gypsum plasterboard sheets.
• Frameless – gluing or direct fixing of the sheet to the rough surface.

In the following situations, fixing the material without a profile is done:

1. If the walls are curved by no more than 5 cm.
2. No need to hide wires and communications.
3. In a small room (toilet, bathroom), where it is not possible to allocate centimeters for the construction of the lathing.

Current methods of installation

The following techniques can be used to fix gypsum plasterboard without the need for lathing:

1. Gluing the material to the rough base with mastic or glue. To do this, apply a solution to the curvature, also apply it in a checkerboard pattern on the sheet. The gypsum plasterboard is applied to the wall, leveled and pressed, additionally installing a holder. There should be 10-12 mm from the floor to the gypsum plasterboard. For this, you can put a small piece of sheathing material.
2. Use of self-tapping screws, foam rubber. This method is used for large curvatures. Fixation is carried out as follows:

• make markings for the material;
• drill 9-12 holes on the gypsum board. Their location is transferred to the rough base;
• glue pieces of foam rubber near these holes on the back side;
• insert a dowel-nail sleeve (plastic part) into the base according to the marks;
• screw the sheet to the wall with self-tapping screws.

1. Combined method. Beacons are installed from below and above. Fill the middle with glue.

For various surface irregularities, all of the techniques for attaching the sheet to the rough base are suitable.

Advantages of cladding using the frameless method

The frameless approach addresses the following issues and has unique features:

1. leveling surfaces without taking up centimeters of the room;
2. plasterboard structures improve sound insulation;
3. there is little insulation of the room;
4. relatively quick installation;
5. budget option – no need to buy profiles and components.

How to use your hands to sheathe a plasterboard wall without a frame or profile

It is only acceptable to face the base without a profile if the unevenness is no greater than 2 cm. Materials and tools needed to use this method are as follows:

• a set of spatulas with different blades;
• level, rule;
• a container for adhesive solution;
• adhesive mixture;
• primer, roller, brush;
• reinforcing tape;
• putty for plasterboard joints.

Once you’ve gathered all the supplies and equipment, you need to get ready.

In order to accomplish this, the walls need to be cleared of any prior paint, wallpaper, or decorative plaster. After dusting, the entire surface is primed.

A plumb line is suspended from the ceiling in order to measure the total vertical curvature.

The drywall is then prepped and installed. The drywall sheet needs to be cut for convenience if the installation is done by one person. Holes are cut in the prepared material for switches and sockets. Using a plane or milling cutter, a chamfer is created on the material’s cut end portions.

On which walls can you install gypsum fiber board without a profile

Glue can be used to install gypsum boards without a profile if the differences are no greater than 2 cm. Using "blobs" to apply the glue is preferable. The material containing the adhesive composition is then leaned up against the rough base after being evenly distributed throughout the sheet. The sheet needs to be lined up; it needs to be perfectly vertical.

Next, the plasterboard is gently tapped so that the excess glue extends beyond the edges and fills in the uneven areas of the rough base. The spatula is used to remove them. The sheet needs to be secured using a glue-setting holder. The next sheet is not installed until the composition has solidified.

When is it necessary to partially finish walls with wooden slats?

Use a different adhesive method if the base has more than 2 cm of unevenness. On the uneven surface is a grid made of wooden slats. Cut the sheet of gypsum board into strips that are 10 cm wide if there aren’t any. Using adhesive, the strips are attached to the wall. You have to wait for it to dry completely. Eight 16 cm wide strips for each sheet of plasterboard should be present at the joints. Every glued beacon needs to be perfectly vertical. matched the level.

How to screw the sheets into the screws directly during installation

An alternative method exists for attaching the finishing material to the uneven surface in the absence of a frame. This is screw-mounted wall cladding. This approach, however, works best when the surface is uniform and devoid of variations.

Here, there are subtleties:

• before fastening the plasterboard with screws, you need to check how easily the fastener enters the rough base;
• drywall is attached to the wall to improve sound and heat insulation;
• it is not necessary to clean the surface before fastening.

It’s easy to screw a screw into brickwork. In this case, the plasterboard acts as the base’s dry plaster.

Dowel nails are used because it is challenging to screw a screw into concrete slabs. Here’s how they go about it:

1. Apply GKL to concrete.
2. Make holes in the material so that this hole is also in the base.
3. Remove the gypsum board.
4. Drive the plastic part of the dowel-nail into the concrete.
5. Place the sheet back in place and screw in the screw, which goes into the plastic sleeve.

The wall is fixed with gypsum board. Make more holes in the sheet to allow the mounting foam, which acts as glue, to pass through for strength.

Does the wall need to have more fasteners installed?

The adhesive mixture needs time to solidify after the first sheet of gypsum board is attached to the uneven surface. The sheet has to be further fixed in order to achieve this. Use extra fastening to ensure that the sheet is not held against the wall for an hour or longer:

1. A homemade device made of wood similar to a mop. For this, the vertical stick should be at least 1.5 m, the horizontal one should be equal to the width of the sheet. The horizontal strip should be smooth so as not to damage the material. It is placed against the fixed material. Moreover, the vertical rail is fixed to the floor (so that there is a stop).
2. A homemade device made of profiles is the same mop only made of profiles for lathing under gypsum board.
3. A purchased support. It is assembled from several parts made of metal pipes. The same device serves as a lift for the sheet to the ceiling.

Gypsum board may not stick or may be poorly fixed, falling off over time, if a support is not used for the material while the adhesive composition hardens.

Depending on the surface and the requirements of your project, you have a few options when it comes to attaching drywall to uneven or concrete walls. Installing a profile with support for a more stable base is another option, as is using screws or glue straight onto the wall. Sheathing without a frame is another option. Although the benefits and drawbacks of each method vary, with the correct technique you can accomplish a polished, flawless finish even on the trickiest surfaces.

Sheathing a brick wall: features

When fixing gypsum board, brickwork has a number of features that need to be considered.

1. When fastening the sheet with screws without glue, they will not hold for a long time when they get into the solution. The building has its own movements, the fastener will be unreliable.
2. Gypsum glue, when applied to cement mortar, will not have good adhesion due to the difference in compositions. As a result, the glue will peel off.
3. A brick wall can collect condensation on itself if it is thin and is exposed to outdoor temperature changes. Moisture has a negative effect on gypsum board. In this case, you need to use foam and screws.

The issue of installing gypsum on brick can be resolved in two ways:

1. In the first case, foam is poured into a small space between the gypsum board and the base.
2. In the second case, foam is applied to the surface of the sheet, and then it is fixed to the surface. This case is more acceptable, since it is possible to control the amount of foam applied to the surface of the facing material.

Installing the face material using foam and screws:

1. One sheet is drilled in 9-12 places.
2. These points are transferred to the surface.
3. Pieces of foam rubber are fixed with glue near the drilled holes. It serves as shock absorbers during fastening.
4. Dowels are driven into the wall at the marked places.
5. The sheet is fixed with screws with wide heads, washers are placed under them. During installation, the evenness must be measured with a level and a rule.
6. Having retreated 1-2 cm from the fastener to the side, in GKL drill holes for foam injection.
7. Foam is injected into the hole in small doses. Do not forget – the foam expands.

It takes around a day for the foam to dry before the screws and washers are taken out. Instead, the heads are "sunk" slightly by the use of regular screws.

Is it possible to attach gypsum fiber board directly to a concrete wall without profiles

Because there aren’t many differences in a concrete wall, glue is used to secure the gypsum board.

Following this:

1. The gypsum board sheet is placed on even wooden slats in front of the place of fixation.
2. Glue is applied to it with a notched trowel.
3. The sheet is lifted, a piece of drywall is placed under it so that a gap remains from the floor and leveled.
4. Pressed to the base and secured with a "mop" until the glue dries.
5. The second sheet is fixed after the first one dries.

Beacons made of cut gypsum board strips or wooden slats are used to indicate if a wall is uneven.

Tips and recommendations

It is advisable that you familiarize yourself with the advice and recommendations of the experts prior to installing plasterboard on the walls:

• fixation of the finishing material begins after the entire wiring is done, the floor is laid;
• for gypsum plasterboard installation, the room must have moderate dampness, the temperature must be at least 10 0С;
• the walls must be cleared of finishing and covered with a primer;
• moisture-resistant gypsum plasterboard is applicable for damp rooms;
• the sheet with glue is heavy, so you need to invite one person to help;
• the protruding glue must be removed immediately.

When the installation method is correctly executed and the masters’ recommendations are followed, the wall surface will be smooth and prepared for additional finishing. If there aren’t any abrupt temperature swings and the room’s humidity level is consistently high, the plasterboard structure should last 10 to 15 years.

Depending on the particular requirements of your project, either screws or glue can be used to attach drywall to uneven or concrete walls efficiently. Every approach has benefits, and the decision is primarily based on the intended outcome and the state of the wall.

For those who are dealing with small flaws in their walls, drywall can be quickly and easily attached with glue. This technique reduces the amount of extra framing that is required, which makes it perfect for areas where you want to keep as much space as possible.

Using screws in conjunction with a profile frame provides a robust solution in situations where the wall is noticeably uneven or needs more structural support. This process guarantees a smooth and long-lasting finish by securing the drywall firmly.

Ultimately, determining the best method will depend on the particulars of your project and the state of the wall. You can decide to use glue, screws, or a combination of the two. You can achieve a polished finish that improves the look and use of your space with careful planning and the appropriate materials.
