How to fasten drywall to the ceiling: methods of fastening and cost

The creation of simple and complex ceiling structures is advantageously produced using plasterboard sheets (GKL). The material has good specifications and is relatively cheap. The easiest way to do a single-level suspended ceiling. There is nothing complicated in this process, the main thing is to figure out how to fix the drywall to the ceiling or, in other words, with the technology of mounting the frame and installing drywall sheets.

The following methods of fixing drywall are:

• bonding to the base surface;
• mounting on a metal frame;
• mount on wooden slats.

Fastening sheets to the ceiling with binders

Drywall can be glued to the ceiling and walls without a frame, which saves space. The base surface should be pre-prepared:

• First of all, exfoliated paint or plaster is removed.
• All irregularities are eliminated with putty after preliminary treatment with a primer.
• The surface must be degreased.

In the presence of significant differences and defects, the adhesive method is not suitable, in this case, the frame is used. Also, you can not do without a crate when laying on the ceiling of communications.

Drywall can not be glued to the following surfaces:

• wooden because wood can be resized;
• wet or oily;
• on a smooth concrete surface (first, notches are made on it).

Glue mounting

Drywall is glued to the ceiling with mastic - a reliable and inexpensive adhesive material. You can buy special glue "Perlfiks".

• With a spatula, creamy glue is applied to the surface of the sheet.
• Drywall is applied to the ceiling and pressed. Holders are used to create a tight connection.

Important! The sheets are staggered so that adjacent seams do not match.

• The horizontal surface of the sheet is checked by level, if necessary, the position of the drywall is corrected with a rubberized hammer.

Near windows and doors, glue is applied to the entire surface of the sheet.

You can glue any drywall, for rooms with high humidity choose a moisture-resistant material. It is necessary to distinguish between ceiling and wall drywall: sheets for ceilings are thinner, they are lighter and it is more convenient to attach them.

Mounting on mounting foam and dowels

Foam can be glued sheets not only on the ceiling, but also on the walls. The surface is prepared in the same way as under the glue, but it is not necessary to level the base surface, since there is an air gap between it and the sheets.

• The sheet is attached to the ceiling and through it holes in the dowels are drilled in the surface in increments of 0.5 m.
• The sheet is removed, after which pieces of foam rubber of equal thickness are glued to it from the inside at a distance of 10 cm from the holes, and the expansion parts of the dowels are inserted into the holes in the ceiling.
• Then the sheet is again aligned through the holes with the base surface and attached to it with dowels. A washer is installed under the head of each self-tapping screw.
• The position of the sheet is set using the level. Due to the foam padding, a gap is formed between it and the base.
• A hole with a diameter of 6 mm is drilled near each fastener in drywall and foam is pumped into it. Then, with the help of dowels and a rubberized hammer, the horizontal position of the sheet is adjusted.
• The next day, the washers are removed, and the screws are screwed back with the head recessed. The sheet attached to the foam will be additionally fixed with dowels.

Drywall frame mount

Installation of sheets is carried out in several stages.

Markup

It is carried out as follows:

• On the base surface is the lowest point, which should be transferred to the wall in the nearest corner. The minimum spacing from the ceiling to the metal profile is 25 mm - a value corresponding to its thickness.
• Having departed from the 30 mm mark on the wall, one more mark should be made and moved to all corners, using the building level.

If spotlights are mounted on the ceiling, the frame is indented from the base surface based on their height.

• Using a paint cord, horizontal lines are beaten around the entire perimeter of the room. On them the lower level of the frame will be set.
• Also on the ceiling are the suspension lines with the calculation of the placement of sheets with a width of 50 cm. From the wall, the first mark is made at a distance of 30 cm.

Frame installation

Process mounting the frame for drywall the ceiling will look like this:

• A UD profile is screwed along the perimeter along the marked horizontal line to the walls.

Dowels are selected depending on the density of the wall material (for concrete - 6 × 49 mm). For fastening the profile to the suspensions, self-tapping screws for metal with a size of 3.8 × 11 mm ("bugs") are used.

• U-shaped suspensions are fixed along the lines on the ceiling to the base surface. Installation is recommended not for the ears, but through the internal holes. Then the suspension will not pull down under the weight of the drywall. Impact dowels that hold better when there are voids in the ceilings should be used here. Suspensions are attached to the wooden ceiling with self-tapping screws.
• CD profiles are cut with scissors for metal or are expanded using connectors, and then inserted into UD profiles with a small gap. They are exposed along a horizontally extended kapron thread and attached to suspensions.
• They require precise installation in increments of 50 cm so that the edges of the sheets are located exactly in the middle of the profiles.
• After mounting the frame, make electrical wiring for lighting fixtures. The cable is laid in a corrugated pipe and fixed to the ceiling with plastic clamps. The findings for each bulb should hang vertically. If necessary, embedded elements are made under the chandelier and large lamps to the lower level of the frame.

Installation of drywall sheets

Drywall sheets have a large weight and dimensions. To install them, you need an assistant. But before attaching drywall to the ceiling, additional operations are necessary.

• If the sheets were cut to size, in these places you should make bevels for further sealing joints with putty.
• In addition, holes should be cut in the sheets for the fixtures.

• When everything is ready, the material is applied to the profile, after which screws 25 mm long are screwed in 30 cm increments. To make the head flush, a nozzle is installed on the screwdriver.

Remains close up the seams, for which a serpentine tape is glued on them and putty is applied.

Installation price

The average cost of professional installation of a single-level ceiling without putty and finishing in Moscow and St. Petersburg - 400-600 rubles / m2, a two-level ceiling of a simple form - 500-700 rubles / m2, a curved shape - 800–1000 rub / m2.

Conclusion

From how the plasterboard is fixed to the ceiling and how correctly consecutive technological operations are performed, appearance, reliability and durability depend designs.
