Facing walls with plasterboard sheets in different ways

Use of drywall sheets in design

Facing walls with drywall sheets is one of the best technologies for leveling walls. This simple operation does not give a complete picture of this fantastic invention.
None of the known materials has as many capabilities as drywall. Incredible solutions for its application are embodied in creative ideas and photo projects above.
Design developments for the use of drywall sheets have come close to the boundaries of physical laws. The masters suggest bending drywall in the video, cutting them into fragments, joining them at an angle and in planes, masking various communications under them using the insert method, arranging niches for ventilation and wiring.
This material is suitable for everything - from even claddings on walls and ceilings to openwork slots on freestanding structures.

Features of working with drywall

Before starting work with drywall, you need to make a list of all the works planned for this room. For example, if it will be executed floor finishing, then the previous operation should be the installation of drywall so that the entire structure can be supported on the base of the floor.
The ceiling is hemmed after closing the walls. The technology manual contains phased development of all operations, it is only necessary to determine the tools.

Expendable materials

When applying for help to a specialized company, problems with the preparation and implementation of work on the implementation of design developments are removed. To do the work yourself, you need to stock up on additional materials and tools.
So:

• From materials should be purchased PN. 28x27 or guide profile.
• PP60x27 ceiling profile.
• Itself cuts and direct suspension.
• Of the tools for decorating walls with drywall, you must have a level, thread, plumb.
• Scissors for cutting metal.
• Roulette, screwdriver.
• A sharp knife, like a shoe, for cutting drywall sheets.

Attention: A prerequisite for the installation of sheets is their staggered arrangement, to offset the joints of the sheets and prevent their placement on the same level, especially horizontal.

How to choose drywall

So:

• Assessment of the strength characteristics when bending drywall sheets is formed from the test results of several samples from the batch. 3 longitudinal values ​​and 3 transverse values ​​are taken, the samples have a certain width of 400 mm, are mounted on supports, the sheet thickness is laid in the calculation formula, then the arithmetic mean values ​​are displayed, which are compared with the table data and must correspond to it.
• There are approved documents for fire-technical characteristics, and gypsum plasterboards are distributed according to the combustibility groups G1-GOST 30244, the flammability V3-GOST 30402, there is a smoke generating group D1-GOST 12.1.044 and a toxicity group T1 according to GOST smoke generating ability.
• Currently, craftsmen prefer to use drywall for leveling surfaces. This is due to the excellent properties that drywall has.
• The installation process is simple and carried out without dirt and dust.

Attention: All parameters of sheets, types of edges, sizes are defined and approved by relevant documents.

Drywall technical solutions

Work with drywall sheets can be carried out in rooms with an air humidity of not more than 60%, with a high humidity indicator, sheets are used on waterproof gypsum, or they are additional protected after installation with various films or glazed tiles on waterproof mastics or adhesives. Wall covering a plasterboard sheet of partitions made of bricks and cinder blocks is made when the humidity of these surfaces does not exceed 8%.
The temperature and humidity in the room during the decoration of the walls should correspond to the conditions of their use. Before facing the walls, all special and construction works must be completed, especially finishing, which include plastering, the installation of cement screeds and others.

Frameless technology

In this cladding, gypsum plasterboards (GCR) are used, it is better not to use gypsum fiber sheets. Plasterboard sheets are not glued to lime plaster.
The base for gluing sheets should not interact with frost, rain and other precipitation:

• GKL fastening, having normal absorbency, is carried out by putties or adhesives of specialized companies.
• To prevent moisture leakage from the glue, hygroscopic walls that can absorb moisture are treated with primers.
• Primers are also used to increase the adhesion of walls. Consultants-sellers of specialized construction stores give the necessary advice. The price depends on the manufacturers of materials, it can be both domestic and foreign firms.
• The technology of three options for gluing sheets has been developed, depending on the unevenness of the walls.
• The roughness is less than 4 mm, then the drywall sheets are glued immediately to the walls with gypsum putty. It is applied with longitudinal beds, a thin layer around the perimeter and center.
• The unevenness of the base is in the range of 4-20 mm, here it is necessary to switch to the adhesive method, which is applied in heaps every 30-35 cm, also around the perimeter and in the middle.
• Surfaces with irregularities of 20–40 mm require a combined approach. The plasterboard strips with a width of 100 mm are pre-fixed with glue, and then the plasterboard sheet is glued to them with putty.

Attention: The places of fastening of heavy objects - window and door lintels, the spaces behind the sinks and kitchen sinks are glued with plates over the entire surface, and not pointwise.

• Installation of the cladding is carried out before laying the finish coating on the floor. The air temperature should not be lower than 10ᵒС in the room.
  Sheets must be laid there for at least 2-3 days before installation. Sheets are cut at a given height, their joining is possible, but not desirable.

Frame technology

Designer style delights

So:

• Wall cladding with plasterboard sheets with 623 is performed according to the frame technology.
• Accurate markings are made on the ceiling and floor, where guide profiles are primarily located.
• From the profiles cut and fixed on the ceiling, a plumb line is lowered to determine where the profile is mounted on the floor, a contour is obtained that defines the plane in two guides.
• Profile for plasterboard wall cladding fixed to the ceiling and floor with dowels or screws at a distance of no more than a meter.
• In practice, the number of profiles per one drywall sheet has been worked out, at least 3 and two are located at the edges and one in the middle.
• It is calculated simply, the source data is the size of the sheet itself, or rather its width.

Attention: The edges of the sheets are joined in the middle of the profile to connect two sheets on one profile at once.

• Marking on the wall is carried out according to the size of the ceiling profile, along the lines on the walls are installed direct suspensions and PP profiles are fixed.
• The standard ceiling height determines the needs of plumb lines within 3-4 pieces, which are attached to the walls with cuts itself.

Ready-made design for cladding

• To strengthen and increase the reliability of the structure, the vertical racks are fastened together by cross members from the same profiles, using additional “crab” products, sometimes they are replaced by masters with cut profiles.
• All that remains is the installation of drywall and its fastening by itself with hardened steel cuts, which can not be confused with others by their black color.
• Places of neatly and carefully implanted fixtures in the sheets and their joints are putty.
• Facing walls with drywall on the profiles can be considered complete.

The main thing in working with drywall is the correct calculations, installation, combination of technologies, and the most difficult installation of drywall on the first wall will go a lot easier, and if the calculations are done correctly, then there will be much more supporters of these materials.
