Drywall is one of the most common building materials that allows you to speed up the repair process, make it easier and more affordable. Using it, you can easily align walls, ceilings, make arches and even cover the floor. But you need to remember that this is a very fragile material, and therefore you need to work with it with care. This article will help you learn about the important secrets of fast work with drywall.
Basic recommendations when working with drywall
This product is perfect for leveling large irregularities, setting false walls, and other large-scale structures. If you use it for wall cladding, as "dry plaster", then you need to understand that drywall takes up some space in the room, which can sometimes become very disadvantageous for the owner of the room.
Sheets can be fixed with glue
The adhesive mixture is applied in a thick layer to the back of the drywall in vertical stripes using a spatula. With surface irregularities, the composition is placed in lumps of 15 cm along the edges and in the middle of the sheet. It is important to remember that the glue remains operational for 30 minutes after manufacturing, so it is not worth tightening with laying the sheets. Protruding sheets must be tapped with a rubber mallet.
No additional drilling required for fixing sheets to metal profiles with self-tapping screws
This is true, only you do not need to do this work by hand, for this you use a screwdriver or drill. Self-tapping screws - with fine thread and countersunk head.
Installation of the frame has its own characteristics
Tongs are used to connect the elements of the metal frame to fix the beams. But builders often use self-tapping screws, which is incorrect and unreliable and does not allow the sheet to press tightly against the frame. Over time, the fastener can loosen and lose stability, which entails unforeseen consequences in the form of cracks. Learn more about how to deal with cracks and why they occur.
Drill or screwdriver
Screwing in self-tapping screws with a drill requires special skills, and it is also not very convenient, especially when it comes to large-scale fastening of sheets. To simplify the work, you can use a special nozzle - a bit with a limiter, which controls the level of drowning of the screw into the surface. For quick fastening of profiles, a pneumatic concrete tool is suitable.
The edges of drywall have a certain shape for high-quality smoothing of joints
Yes, the beveled semicircular edge makes it easier to putty the joints, you can also place a reinforcing tape around the edges of the sheet, and it will not create bulges on the bases. But what about the transverse joints?
- The seams should be on adjacent panels.
- To fix the horizontal edges from the inside, you need to hem across the joint with a piece of profile, about 20 cm. On one sheet, you need 2 pieces.
- It is also necessary to remove the cardboard sheath widthwise, which will be replaced by the reinforcing tape.
- The joints are sealed with Fugenfüller or Uniflot putty.
Location of fasteners on a sheet
Along the edge, the screws are placed at a distance of 125 mm about 20 mm from the end of the sheet. The material is attached to the middle profile with a pitch of 250 mm; marks must be applied on the front side to indicate the place of fixing the screws. At the corners, the screws should be fastened away from the edge where the higher strength exists.
Drywall should not rest on the floor
In order to avoid subsidence of the structure, it is imperative to leave a gap of about 1 mm between the floor and the drywall sheet. It must be placed on the liner using cuttings from the same product.
The frame of the suspended structure of the ceiling and walls is different from each other.
In order to avoid mistakes when installing sheets on the ceiling, high requirements are imposed on the frame structure. The product is mounted with a pitch of 400 mm, each sheet is held by 4 profiles. You cannot save on this, so that the platform does not sag over time. To attach the ceiling hangers to the base one, you must use metal dowels-wedges or anchor bolts, but not plastic. Use Knauf Nonius hangers, or fix the profile pieces firmly to the ceiling.
Rigidity of plasterboard partitions
You should not save on this! To quickly and reliably assemble the frame, you need to use a cutter for the drywall profile, which does not leave dents when joining, does not require hole marking, and makes the edges of the product even and smooth. There is no need to use fasteners.
The frame is sheathed on both sides with plasterboard, and the inside is filled with soundproofing material.
- The profile should be at least 6 mm for the best strength and reliability.
- The screws should be galvanized or made of stainless steel. They should penetrate at least 10 mm to the depth of the sheet, and about 20 mm into the tree. It is better to immediately coat the hats with alcohol varnish to avoid corrosion.
- The type of profile is selected depending on the height of the room and the load on the frame. For a 50 kg structure, you need to supply a frame with a thickness of 15 mm.
How to avoid gross violations and damage to the material
Lightweight ceiling sheets with a thickness of 9 mm cannot be used to form partitions. Even when using them for their intended purpose, you need to take the correct step of the profile, without various magnifications (this is necessary to save fastening material).
It is forbidden to abandon the soundproof tape when erecting partitions. And also save on fiberglass or mineral wool, forming the inner part of the profile.
It is better to fix drywall with a screwdriver with a drilling depth adjustment function.
Do not sheathe concrete walls or bricks with plasterboard. The walls must "breathe", and, therefore, it is necessary to leave a gap of 2 mm between the materials. It can be glued with tape or filled with silicone.
The secrets of drywall are that when choosing it, you should pay attention to special marking:
- GH13 - standard;
- GN113 - moisture resistant;
- GEK13 - increased strength;
- GTS9 - moisture and windproof;
- GN6 - for renovation work.
For walls, the optimal sheet thickness will be 12 mm, for the ceiling - 9.5 mm (on the ceiling, in order to avoid cracks, use gypsum plasterboards in 2 layers). It is rational to use two layers in case of serious loads on the structure.
Additional accessories for work
To work with the drywall profile more efficiently, you can use a special stand for attaching the sheet to the structure. And to transfer large sheets from place to place, a construction grab is used, which does not leave dents and is very convenient to use.
For cutting sheets, a regular painting knife is suitable, with which the edges of the material are cut. To fix the plasterboard shelves, it is necessary to use dowels-umbrellas or butterflies, if the structure is very heavy, then it is important to choose self-tapping screws of the appropriate length for firmly fixing the product. But for quick work with a plasterboard profile, you need cutter pliers.
How to remove a scratch from a sheet
You can use reinforced paper tape, before that, expand the damage with a knife and lubricate the hole with putty. Glue the tape on top and press it into the plaster with a spatula. This method will help preserve the damaged sheet of building material.
What needs to be done to properly bend the drywall sheet and not spoil the product
The secrets to working quickly with drywall are in the following steps:
- On the outside of the sheet, make deep serifs with a knife, then place the sheet on the edge and bend it.
- Use a needle roller to make many small holes on the inside of the material. Then moisten the sheet with water and bend after a while.
After breaking off, the surface must be sanded with a bar or plane.
To get holes in drywall, it is best to use a circular cutter.
Such profiles help to build any door arch of various architectural solutions. To do this, make cuts on the profiles with a construction knife in increments of 6 mm. Next, put it on drywall, circle the structure with a pencil, then cut it out along the outline. Attach the profile with self-tapping screws using a screwdriver.
How to make it easier to work with drywall
If the base on which the sheet is mounted is flat, it is easy to drill, for example, the inside of a wooden house, then you can fix drywall directly without a case. In this case, the fastening screws, screws, dowels must be of the appropriate length.
If the house is new, then in order to avoid planting the structure, it is important to use an aluminum frame; it is better to assemble complex shapes under the supervision of a specialist.
You can fix the sheets with a solution that will help remove voids and create a flat surface.
It is better to knead gypsum putty in small portions - for ease of use. It is not necessary to use high rotations of the hammer, thereby damaging the quality of the composition. Before hanging the next portion of the mixture, it is necessary to thoroughly wash the old solution.
To obtain stronger external corners of the structure, you need to use a corner protective profile, which is fastened with screws at a distance of 15 mm. To strengthen the inner corners, plaster putty is used, after which the surface is leveled with a construction trowel. More details about the arrangement of ugov.
In order to properly attach vertical structures and extend their service life, it is important to screw in the screws at the edges of the sheet at a distance of 20 mm, and in the center - 30 mm.
These are the simple secrets of drywall installation that professionals advise. They will help not only to reduce the installation time of plasterboard products, but also to do the job quickly, durable and efficiently. But is it difficult to install anything in this building material and not?
