How to bend plasterboard in a semicircle: make a wall, for a ceiling, video

The need to bend the plasterboard arises if you need to beautifully decorate the ceiling or make an arch In demand and multifunctionality, drywall will give odds to many other building materials. And they make of it constructions sometimes of the highest complexity. Including, for this purpose it is often necessary to bend drywall. So how do you do it right?

Types of drywall: how to make a gypsum board semi-circle

The first thing to consider is the thickness of the GCR.Plates of 12 mm thickness are easy to bend, special devices are not needed for this. But if you want, for example, to bend a gypsum board with a radius of up to 130 cm, then you should take a sheet with a thickness of 9 mm.

Actually, any kind of drywall can be bent. But some are more predisposed to this.

The semicircular plasterboard should be carefully fastened to the frame using screws

Types of plasterboard:

• Ceiling. It is used to correct the height of the base ceiling surface, to hide communications, to change the shape of the ceiling. Has increased moisture resistance.
• Wall. It is used for leveling and covering the walls in the room, for installing interior partitions.
• Arched. Used in the installation of arched openings of the room. The composition of the drywall sheet improves with the addition of fiberglass, this gives flexibility to the material. This kind of drywall is characterized by increased strength.
• Waterproof. And it is used usually in rooms with a moisture content above 80%, in the composition of this material are added elements that do not absorb the liquid. Prolonged protection against fungus is limited. Drywall has a green color.

As you can see, there is something to choose from. Drywall is low-cost, it is inexpensive, it is environmentally friendly material. But its strength in comparison with other materials will be modest. But it can be bent.

Method for bending drywall on dry

If you fix the sheet of gypsum board to the supporting structure with self-tapping screws, you will be able to bend it to a rather large radius of curvature. This way you can use for radii of curvature more than 1 m.

It is very important when working with plasterboard to control the force of pressure, observing great accuracy during installation. If the sheet is thinner, then the radius of curvature will be smaller.

In order to bend the drywall with a dry method, you will need a special shape and a few heavy objects to fix the material on the sides( you can use bricks)

How to bend dry sheet:

• Create the template of the desired size;
• One edge of the sheet on the template is fixed with screws;
• Bend the free edge of the plate according to the template shape;
• Secure the second edge with screws.

But for many there are more preferable ways of flexing drywall. Water is used for them, or, as in the third method, they make incisions. The first, above described method is considered safer.

"Wet" way of flexing of drywall

And this method can be considered the most common. Most of all, this method is good for the construction of arches, as well as built-in niches. It is based on taking into account the natural features of the material. So the gypsum differs porosity, and in case of moisture on the drywall, it will become soft.

With full drying, the gypsum board will retain the curved shape created for years to come.

Let's consider in detail how to implement it yourself.

For wetwalling the drywall requires water, a roller and a mold

As a "wet" way to bend drywall:

• A frame made of OSB( i.e., chipboard) is manufactured;
• Using water at room temperature, moisten the sheet until a so-called water mirror forms on its surface;
• The sheet should be soaked for about 10 minutes;
• In order for the drywall to be evenly moistened, the use of a needle roller( if there is none, the punctures are made with an awl or even a conventional fork);
• Remember that the sheet should not get wet, only the gypsum core must be soaked with water;
• Curl the wet sheet as described in the dry method, and fix it with adhesive tape to the template;
• Dry the gypsum board until completely dry.

Do not worry - contact with the liquid will not change the properties of the drywall. Water only makes it more elastic and flexible. And when the material dries, its properties return to it in full. That is, the gypsum becomes hard again.

Notch way to bend drywall

There are for some reason wetting the sheet can not, the notch method will be convenient. This is also a dry method, only with the sheet is more manipulation. Do not worry, this method will not lead to injury to the sheet.

For the "incision" method, it is necessary to use the clerical knife

Cutting method:

• On one side of the sheet along the folding line, cut cuts at a five-centimeter distance from each other( the knife is also suitable);
• Cutting should be done on the convex side of the sheet - more precisely, the side that will be convex;
• The smaller the expected radius - the smaller the cuts should be;
• The depth of cuts is approximately 2-3 mm to the cardboard layer of the other side;
• The side with the incisions must be straightened with a fan;
• The cuts should be filled with filler to secure the structure.

If a milling cutter is used, the notches can be both U-shaped and V-shaped. That is, a sheet of gypsum board can also take the desired shape. Work carefully and everything will turn out.

Tip: how to make a semi-circular plasterboard wall

This is a separate technology - to make the wall a semicircle. But there are precise clues that precede any of the methods you choose. Take them into account.

When deciding to make a semi-circular wall of gypsum board, you need to use a metal profile that is resistant to damage

For a semicircular wall:

• Use only a steel profile for strength;
• Drywall has a low tensile strength, therefore it is necessary to use special templates for bending;
• If the bend radius is small, wet the sheet before the bending procedure, a "wet" method for such tasks is preferred;
• The wall height must be up to the ceiling if you want ease of installation.

Any of the three methods can lead to the desired result. Correctly selected tools and accuracy in technology will help to cope with the task without losses. Well, of course, drywall should be of good quality.

That is why the GKL is so popular that it gives considerable opportunities in repair work. And this despite the fact that its price is more than affordable. Try and you change the look of your home due to inexpensive, natural and pliable material.

Good work!
