A universal building material is drywall.

It’s used to level walls and ceilings, cover communications and pipes, and make a lot of interior items.

Under certain circumstances, the drywall wall in the bathroom will be level, useful, and long-lasting. Their adherence is required.

Is it possible to use drywall in the bathroom

Drywall releases a range of kinds. Its thickness, size, and sense of belonging make it unique. Three prevalent and frequently utilized species are:

1. Ordinary GCL gray. The size of the sheet reaches a maximum of 4.8 m, its width 1.2 m, thickness from 8 to 24 mm. We apply as dry stucco for leveling walls, ceilings, creating niches and other items.
2. Green moisture -resistant GKLV. Drywall sheets are treated with means that do not pass moisture. They are used to create niches, level walls, ceilings, produce boxes for pipes in wet rooms. These are bathrooms, toilet, balcony, attic.
3. Fire-resistant gypsum board – drywall that does not burn. Used for finishing fireplaces and walls near stoves. It is also used in areas with a high fire hazard.

Gypsum plasterboard must be used in the bathroom. If installation is done correctly, you can keep your appearance tidy for 15 to 20 years. After being laid out on drywall, tiles are painted. On a gypsum plasterboard wall, you can hang shelves and drawers for bathroom accessories.

Which drywall to choose

There are two types of drywall options that are used to level the bathroom wall:

1. GKLV – green. Sheet thickness 12.5 mm. Height and width depend on the manufacturer. This type is used for leveling walls, hiding pipes, creating a suspended ceiling.
2. Fire-moisture resistant GKLVO. This type is produced by Knauf. It has the ability to both resist moisture and not burn. It is also used to level walls, ceilings. In places where there is a risk of fire in the wiring (old) or in a private house the wall is a stove, then we will apply this type.

Gray gypsum board is not suitable for use in bathrooms. It will soon enlarge and distort. The finishing will stop being functional. The likelihood of fungus developing is high.

Under the tiles

The bathroom floor tiles are covered with moisture-resistant gypsum board sheets. It is more robust and denser. Walls can be covered with 12.5 mm thick sheets. Here, there are subtleties:

1. GKLV cannot be glued in the bathroom. They are mounted on a metal frame. The frame base is made with transverse horizontal profiles. This is used as a reinforcement of the base, capable of withstanding the weight of the tiles and glue.
2. It is imperative to reinforce the joints. For this, use reinforcing tape and putty for joints. The putty should be chosen moisture-resistant. Let"s say, Knauf "Uniflot" – universal, "Fugen" – moisture resistant.
3. All metal elements – profiles, fasteners, connectors must be galvanized or coated with an anti-corrosion compound.
4. Before creating the frame, the rough base is treated with a water barrier.

If these guidelines are not followed, moisture will seep onto the rough base, causing fungus to grow. The final coat will stop being functional.

For painting

The bathroom’s paint job is done on green plasterboard. The installation process is done using a frame base. You can make high-quality repairs with a 15-year shelf life by following this sequence of work.

In order to guarantee the length of the repair, you must abide by the following rules:

1. Drywall and its components must be from the same company.
2. Before creating the frame, it is imperative to cover the rough surface with a water barrier.
3. All joints are reinforced. All fasteners are covered with moisture-resistant putty for joints.

Apply a wet room primer to the surface before painting. This will shield against moisture and enhance the beauty of subsequent finishing.

For alignment on the frame

Establishing a frame base is necessary in order to align the walls with moisture-resistant plasterboard. Work with the rough base first, though. The surface is completely dry. Next, apply a waterproofing material to it and allow it to dry.

Zinc-coated profiles are used to construct the frame base. In order to give the entire structure strength and rigidity, crossbars must also be installed.

It is necessary to apply an anti-corrosion agent to fasteners. They are essentially offered in black.

Drywall is attached with chamfer and two to three millimeter gaps. Reinforcing tape and moisture-resistant putty are used to cover joints. Cover the fasteners as well.

What thickness should the gypsum board be

Similar to other varieties, moisture-resistant drywall is made in various thicknesses. Sheets with a thickness of 12.5 mm are chosen in order to align the walls. Shelves and niches, as well as arches and suspended ceilings, are all made with thin gypsum board. For the floor, thicker GK lists are utilized.

How to sheathe

Drywall is positioned in line with the wall and fastened to a frame made of galvanized profiles. To achieve this, carry out rigorous phased work:

1. The surface must be prepared. Dry, clean, cover with waterproofing material.
2. After that, make accurate measurements to calculate the number of necessary elements.
3. The next step is the markup. To do this, use a laser level, plumb line, upholstery cord or marker. It is important to monitor the evenness of the intended strips.
4. The markings fix the profiles. Directors are attached to the floor and ceiling dowel-claws. Harshes are attached to the wall with a step of 40 cm. They fix the rack profile PS (CW).
5. Between the rack profiles horizontally, with a step of 40 cm, transverse. They are cut out of a rack profile. Crabs are used for fixation.

1. The entire created frame is checked for strength and rigidity.
2. The sheets of plasterboard are fixed to the metal base. First, the whole ones, and then the remaining windows are closed. The sheets must be fixed in a checkerboard pattern so that the horizontal joints do not coincide.
3. After that, the plasterboard wall is covered with a primer and allowed to dry.
4. The joints are reinforced, the fastening points are covered with putty for joints.
5. Next, the entire surface must be puttied and primed again.

The wall can now be completed. If everything is done properly, the surface will be sturdy, smooth, and able to support a specific load.

Care

Plasterboard walls don’t need to be taken extra care of.

Water stains on tiled walls must be removed, and wet spots shouldn’t build up on the floor. Since acidic detergents erode the grout between tiles, you can use non-acidic ones instead.

Steer clear of getting water on painted walls. If not, wipe right away. Use of detergents containing alkali and acids is not advised.

In the bathroom, green plasterboard that is resistant to moisture is installed. It is not frameless; instead, it is fastened to a frame base composed of galvanized profiles.

If the lathing and gypsum plasterboard are installed correctly, the wall can be tiled and shelves or boxes for bathroom accessories can be hung on it.

Plasterboard sheathing is a useful and efficient way to get your bathroom walls ready for tiling. Choosing the proper plasterboard thickness is essential for stability and longevity, particularly in a bathroom that is prone to moisture.

A smooth and even surface that is prepared for the application of tiles can be achieved by following the step-by-step instructions for plasterboard installation. Every stage of the process, from measuring and cutting to fastening the boards and caulking the joints, is crucial to the overall caliber of the completed walls.
