Angle of plasterboard: how to make

Drywall has always been very popular among the entire range of finishing materials. With its help, you can create surfaces of any geometry and complexity, and the work takes a minimum of effort and time. But to get the perfect result, you need to learn how to make even angles from plasterboard. This is necessary not only from the aesthetic, but also from the practical point of view. Today we will talk about how to make a corner from plasterboard with our own hands.

Need for creating even angles

When plastering walls or creating separate structures, for example, a box orit is very important to properly mount the corners. Otherwise, the work will look at least unattractive. The uneven or weak corner also of the

will cause the to collapse quickly or become deformed. Special installation technology provides additional fixing points. They strengthen the strength of the entire structure and allow it to withstand various loads.

If you make the plasterboard wall covering, but do not pay enough attention to the corners, then cracks will appear very quickly at the intersections of the sheets. Below we describe in detail several technologies for creating gypsum cardboard corners, which are applicable for the construction of niches, boxes, walls and even cabinets.

There are external and internal corner from gypsum board, the technology of which has its own peculiarities. Let us consider in more detail each of them.

Inside corner from the drywall

If you are laying walls, making a cabinet or a niche, without arranging the neat interior corners simply can not do. Make them pretty just , the main thing is to follow the instructions and stock up on the necessary building materials. Fortunately, they will need a little.

For work you need to make a metal frame from the rack profile. Depending on the functional purpose and the load on the future design, different types of profiles are chosen. So, to mount strong internal corners of the ceiling from gypsum board, it is necessary to purchase the rack profiles PS or CD.It is important to choose a quality profile, if you do not want it to deform, and over time, cracks along the wall.

For mounting, you need to connect two lengths of profile with metal screws for a length of approximately 90 mm. Self-tapping screws should be set in increments of 25 cm - 30 cm, so that the structure is stable. The distance between the fasteners depends to a large extent on how much rigid is the base, and for internal gypsum cardboard corners the maximum rigidity of is required, otherwise they fall off under their own weight.

Another is a mandatory requirement for the installation of profiles in the interior corners - the presence of a perfectly smooth and smooth surface. Fortunately, drywall itself is perfect in this respect and does not need additional alignment.

How to make a corner from the profile for drywall:

1. Take a pair of PS rack posts and mark them with a marker in the locations of future attachments.
2. Lay the profiles perpendicular to each other in such a way that one of them sideways abuts against the front of the second. The result should be a right angle.
3. Drill through the drill holes with a nozzle of suitable diameter through holes in the intended locations.
4. Connect the profiles with screws.
5. Along the perimeter of the angle, install the guide profile and insert the resulting rigid angle into it.
6. Secure the angle in the guide profile with the screws.
7. Choose sheets of drywall. In the corners it is best to install slabs with "native" edges ground at 45 °, so that the seam is neat.
8. If the gypsum boards are already cut off, use a knife and sandpaper to remove the bevel at 45 °.
9. At the joint, glue the mesh of the strobe, smearing a little of the putty there, and press it down with a corner spatula. Thus, walk through the entire area of ​​the inner corner.

Exterior corner from drywall

To make the outer corner of the walls of plasterboard, you need to act a little differently. To do this, you do not need to create a separate connection frame, since the profiles are not attached from the outside. Arrangement of external corners involves the use of two metal or plastic perforated profiles, which are simply attached to both sides of the wall( it is better to choose metal, because they are more durable and durable).

When fixing the drywall, make sure that it is with uncircumcised edges. Otherwise, you need to take a chamfer to a depth of ½ the thickness of the sheet. To attach the racks to the perimeter , use self-tapping screws for metal.

When you attach the profile, the adhesion surface of the with the plasterboard wall will be increased, which will create an additional guarantee of strength and durability of the finish. Note that during the fixing of sheets to the corner frame profiles, the distance between the screws should be reduced. Also is superfluous to take care of additional sound insulation of walls, especially if speech goes about repair in a city apartment. The drywall itself weakly protects against noise, so the soundproof material should be laid between the frame and the sheets until they are secured.

Another one feature of the design of external corners from gypsum board is that between the sheet and the overlap there is an empty space. It can stand idle or benefit, hiding in itself various communications and wires.

Important: Chamfer at 45 ° must be removed without fail. This is to ensure that the metal corner does not protrude and fit well into the created recess. Also with putty the joints the area of ​​adhesion of the solution to the surface becomes larger.

How to make an external corner of gypsum cardboard with your own hands:

1. Prepare the necessary materials and tools : building rule, tape measure, level, screws, gypsum-based adhesive, perforated metal profile.
2. Check the angular profile for the straightness along the entire length. Because it is made of flexible material, it could bend during transport. If the slightest bend is detected, it does not make sense to align it - it is better to postpone this material for more rough work.
3. Measure the length of the angle with a tape measure. The angular profile must be shorter than the length of the angle by 2 - 5 mm.
4. Attach the profile to the surface of the corner and strongly press the entire length of the building rule so that in the gap no remains with the slightest lumens.
5. Do not let go of the rules, apply the level and check the verticality of the corner. In case of abnormality, press or release it.
6. Fix the corner in a strictly perpendicular semi-position and attach it with screws to the plasterboard wall. Only after the profile reliably is fixed , you can remove the rule.
7. Prepare the gypsum glue, dissolving it to the consistency of thick mastic. Put his spatulas on the shelves of the angular profile rather thick layer. It is important that the glue fills all voids between the profile and the drywall sheets.
8. Wait a little so that the glue begins to grasp, then unscrew the screws and grease the holes left by them. Remove the excess adhesive with a spatula until it is frozen, so that the corners are even and neat. To do this, place the tip of the spatula strictly perpendicular to the corner and swipe the from the top to the bottom with one movement, "cutting off" the glue.

When the glue dries, grind the surface thoroughly. After that, you can proceed to the primer, putty and decorative finishing.

Methods of fastening drywall

The method of fixing gypsum board when creating angles directly depends on the nature of the device of this angle. So, if you trim the frame into one sheet, the adjacent elements of the outer corner will overlap. For this reason, the end part of the plasterboard in the corner must be cut to the very gypsum( it is necessary to completely clean the cardboard shell).If this is not done, puttying the corner will be much more difficult.

When installing internal corners, gypsum board is also recommended to be cleaned from the cardboard layer. If the coupling is T-shaped, the end parts are cut off at by an angle of 45 ° for more of the convenient putty .

If you are laying a frame in two sheets of plasterboard, the elements will certainly move.

Decorating plasterboard corners

If you have mastered the installation, the finish of the corners of drywall will seem to you a spittle case. Even those who have never worked with with sponge-filling mixtures, can easily cope with the finish of the plasterboard surface. But before taking a spatula in hand, the design and angles must be covered with an adhesive primer of deep penetration. It will protect the material from moisture from putty and give it more strength.

Very popular primers of the German manufacturer Knauf, as which you can be sure of 100%, albeit at a fairly high cost. Apply a primer with a roller or a wide construction brush, carefully working each centimeter of the surface. When drywall dry, you can proceed to putty .

How to putty the corners of plasterboard:

1. First of all apply putty on the grooves left by the screws in the corners, and then proceed to the processing of joints and joints.
2. When working on joints, use a reinforcing mesh, cutting the its into parts and gluing over the joining of the sheets, including in the corners. You can glue the mesh on a regular building PVA .
   
3. After the glue has dried, apply the layer of the putty and level it as far as possible. Do not try to immediately get a perfectly smooth surface - even with professionals this goes not always. When decorating the outer corners, first check the levelness with the help of a level and then proceed to grinding. If a deviation is detected, apply some to the desired location of the .
4. After drying putty in the corners of gypsum board, grind the surface with emery paper with a small grain size. Thus, you will get rid of of and bumps.

To sum up, we suggest that you familiarize yourself with a useful training video about gypsum board corners and the specifics of their putty :

joints in are the most vulnerable component. Due to the high brittleness of the material, it is very difficult to obtain an ideal joint of the corners. At the same time, corners are the most visible part of any structure, where irregularities and defects are immediately evident. That is why it's important to use straight metal profiles and do not spare the screws for their fastening. This is the only way to get neat internal and external corners in plasterboard buildings.
