How to cut gypsum board

There are several useful tips that will facilitate the work:

• Drywall is a flexible material. In order not to break it during operation, it is necessary to put the sheet on a stable flat surface.
• When cutting a large sheet, you should do this gradually.
• At the workplace, there should be no moisture, otherwise the material will become wet and become unusable.
• On which side to cut drywall, it is not so important. However, it is best to cut on the surface, which it will be attached to the wall.
• Cutting the profile, do not worry about uneven edges. They are subsequently closed with a sheet of plasterboard.
• When working with the material, it should be understood that it can crumble and create dust. Be sure to protect eyes and respiratory system.

Straight lines cutting

First, it is necessary to put gypsum board on a flat horizontal surface and To mark on both sides sides of the line along which the cut will be made. After that, a metal ruler is applied to them and pressed by hand. In the other hand, we take the knife and run it along the line several times, so that the cut becomes deeper.

Some believe that they will cope well without a ruler. However, it should not be neglected. To make a smooth cut without it is quite difficult. Of course, this is possible, but you have to spend time to make the edge neat. With the ruler, everything is done much faster.

When the cuts become sufficiently deep, the sheet of plasterboard should be placed on the edge and knocked on it from the back side. Usually a few weak strokes lead to a break in the drywall cloth along the line. Now it remains only to cut the cardboard layer with a knife.

If you do not have a jigsaw, you can use a hacksaw or a construction knife and a hammer. Make deep incisions strictly according to the markup. Place the drywall on a flat surface with a recess so that it is under the cutout hole. Now hit in this place with a hammer. After the unnecessary part falls off, turn the drywall and cut off excess paper.

Edge processing

When drywall is cut off, its edges should be leveled slightly so that they do not have Chipping and chipping. You can do this with sandpaper. Carefully go through all the edges of it until they become smooth.

In the final stage of the preparation of the material is its fascia. For this, it is necessary to cut several millimeters of gypsum from each edge (about two-thirds of the thickness of the sheet). The chamfer is removed by a plane or knife at an angle of approximately 45 degrees.

After installing the drywall, all the crevices between the webs of the material must be ground. When the seams dry, you can start painting the surface or pasting it with wallpaper.

Drywall sheets are attached to a special profile. It is made of metal
For the greatest strength of the structure. Than to cut a profile for gypsum cardboard? To cope with this work you can use:
