Characteristics

Moisture resistant plasterboard( abbreviated as CGLE) is a building material that is used in the bathroom for different purposes: leveling walls or ceiling, creating additional partitions, arches or walls in the premises.

KGLV sheets are impregnated with a special substance that protects the material from moisture and water ingress. Moisture-resistant plasterboard is very popular among buyers, because it has a small weight, it is easy to work with, and the material is environmentally friendly material. Drywall is sold in sheets that have standard sizes, which allows you to calculate the required amount of material before construction or repair work.

Types of

The main types of drywall that are used for repair, construction and finishing works:

  • wall plasterboard is used for wall finishing. Experts do not recommend using it in dry rooms with a high air temperature, as the material loses its strength and becomes brittle;
  • ceiling KGL allows you to create multi-level ceilings, which perfectly emphasize the interior of the room. Suspended ceilings make it possible to hide all irregularities and save money on leveling the ceiling. Under false ceilings the wiring is perfectly masqueraded and it is convenient to mount various lighting systems in them;
  • fireproof gypsum plasterboard refers to universal materials. It is often used for ceilings or walls in the bathrooms of wooden houses, where there is an increased risk of fires. For small rooms with high humidity it is better to use moisture-resistant gypsum board, since the fire-resistant type absorbs moisture and begins to sag with time;
  • moisture-proof KGL is perfect for use in rooms with high humidity. On the surface of a moisture-resistant type, it is easy to fix a ceramic tile or other finishing material;
  • arched plasterboard is used to create arches, because it is characterized by high strength and flexibility. To create arches and walls with large bends, this type of material will be the best option.

Features of the ceiling device

Installation of drywall is quite simple, even a novice without any experience can independently perform the installation work. It is necessary to adhere to a certain sequence of actions when creating a metal frame for gipsokartonnye sheets. First you need to measure the room, create a drawing of all structures and purchase all supplies and prepare tools. To create a metal frame, you need to use a drill-screwdriver.

For the installation of gypsum boards, some tools are required, namely:

  • level;
  • safety glasses;
  • hacksaw, the thickness of the blade should be 1.8 cm;
  • side cutters;
  • electric jigsaw or scissors for working on metal;
  • hammer;
  • knife;
  • pliers;
  • tape measure, pencil and plumb line.

Materials that will be needed for the ceiling:

  • sheets of moisture-resistant GCR;
  • primer;
  • metal profiles;
  • self-tapping screws and nails-dowels.

First you need to wait some time before installing the moisture-resistant GCR so that it can adapt to the air temperature in the room. This prevents the possibility of deformation of the sheets at a temperature drop.

Installation of gypsum board on metal profile

Ceiling installation in the bathroom using a metal frame:

  • You should install the profile guides to the ceiling, using nails-dowels along the entire perimeter. To check the smoothness of the fasteners, use a level or plumb. Then a rack-mount profile is attached to which horizontal jumpers are attached. This completes the installation of the frame.
  • It is necessary to conduct all communications, and determine in which places there will be holes to make the laying of electric wires. Communication is best hidden in the corrugation to prevent possible fire or mechanical damage.
  • The skeleton is skinned with sheets of moisture-resistant plasterboard. Self-tapping screws are used to fix the GCR.During installation, the sheets should fit tightly against each other, and then it is necessary to close all joints with a reinforcing tape and treat them with a moisture repellent filler. By the same technology, all angles are processed. The use of sealant will create a reliable protection against excessive moisture in the bathroom. To strengthen the structure, two layers of sheets are used, while the second layer of drywall is fixed to ordinary glue. If lighting is installed in the ceiling, only use special moisture resistant lamps that can be used in rooms with a high humidity level.

Ceiling installation in the bathroom without the use of a metal frame:

  • Preliminary preparation of the ceiling. First, you need to cement all potholes and cracks, then treat the ceiling and drywall sheets with a primer in order to conduct a deep disinfection. Joints between sheets should be smeared with mastic, which has water-repellent properties.
  • Special adhesive is applied to the ceiling and sheets using a roller or paint brush. Use only a moisture resistant adhesive. Then the sheets are glued to the ceiling and pressed firmly against the surface.
  • For additional protection, all seams and joints must be treated with sealant.
  • When the ceiling is completely sealed with plasterboard, you can proceed to plastering with a special moisture-resistant mixture, lining or painting.

Decorating the walls of the bathroom KGL:

  • At first, it is desirable to make the walls align with the frame. If this is not possible, then the sheets of plasterboard can be fastened to the walls immediately, but it is always good to prepare them beforehand.
  • It is necessary to create a reliable waterproofing all around the perimeter of the room. All edges of sheets of water-resistant plasterboard should be treated with mastic or wrap a waterproofing membrane. Particular attention should be given to those places where the connection with the floor covering or ceiling will be made.
  • To create a reliable resistance to moisture, one day before the installation work, each sheet should be treated with a special water repellent.
  • Seal each wall separately.
  • Many experts recommend using a metal frame to avoid problems in the future. The frame will occupy several centimeters of space, but this gap can hide all the communications of the bathroom.

To create an original design, you can make the wall concave or convex. KGLV acquires the necessary form quite easily and quickly.

Procedure:

  1. The drywall sheet should be well watered, shaped and allowed to dry for a while. To moisten the sheet it is better to use a roller with metal needles, then the moisture will quickly fall inside.
  2. Next, the sheet should be covered with a damp cloth.
  3. When the sheet dries, you can do this several more times, which completely prevents possible breaks of the sheet on the bends.

Drywall cladding

In the bathroom for finishing surfaces created from sheets of moisture-resistant gypsum board, you can use different types of finishing materials:

  • cork;
  • ceramic tile and mosaic;
  • paint and decorative plaster, but only moisture resistant;
  • special waterproof wallpaper;
  • plastic panels.

When selecting the finishes, remember that the material used should not be afraid of high humidity in the bathroom. If it is correct to create a covering of walls and ceiling with drywall sheets, and also to remember good ventilation, walls, ceiling, partitions or niches will have a long service life.

Table tops, shelves, screens for baths from plasterboard

Drywall in the bathroom is used not only for walls or ceilings. It allows you to embody many design ideas and give the room the originality. All pipes can be hidden under plasterboard, so that non-aesthetic communications are not visible. As the pipes need constant access, it is possible to make a window that will be covered with a special removable plastic plug.

KGL can be used for skinning the frame for the bathroom screen. Further, it can be glued with tiles to create a cozy atmosphere in the room. But you need to try not to get water behind the bath, because in time, constant moisture will lead to deformation of moisture-resistant plasterboard sheets. Therefore, it is better to think about reliable waterproofing immediately.
