Dry plaster is sheets of composite building material based on gypsum with cardboard outer surfaces. The main part of the total volume of the sheet, about 93% is a soft core, about 6% is cardboard and no more than 1% is moisture, starch and various organic surfactants. Strong and reliable building board serves as a frame.
In addition, it is very convenient to apply all building materials on it: wallpaper glue and paint. This is a fairly plastic material.
Today, there are new technologies for the use of this material - this is dry construction, in which there is no need to use wallpaper.
Dry plaster was developed specifically for use in residential buildings, so it meets all government standards. It is an environmentally friendly, clean, harmless and non-toxic material.
This material is also referred to as energy-saving, non-flammable materials. The plaster has excellent sound insulation properties and characteristics.
Has no specific smell and is safe for human life.
This building material is breathable, often of excellent quality, and controls the level of humidity in rooms. With an increase in air humidity, it will absorb it, and with a decrease, it will release it. Its acidity is the same as that of human skin, and it is harmless to health.
When decorating walls, dry plaster will be universal building material.
Working with her is simple and comfortable. Wet mixes such as putty or cement are not used during installation and assembly.
Usually, electrical cables and communications, as well as various plumbing systems, are installed in the space between the sheets and the wall. In addition, if necessary, there is an excellent opportunity to insulate the renovated premises. To do this, it will be enough to purchase special glue for foam and expanded polystyrene plates, which will be easy to mount and hide behind gypsum plasterboards.
Like any building material, dry plaster has its drawbacks. The disadvantage of using this material is the inability to use it in rooms with an air temperature above 45 ° C.
If the sheets are overheated, it breaks chemical relationship between gypsum and water molecules, which immediately begin to evaporate. And the strength of the product decreases several times.
Since gypsum plasterboards do not tolerate high humidity and get soaked, they are not recommended for use in humid rooms.
Dry rooms with moderate temperatures are the best choice for surface finishing with drywall sheets. Also, the sheets must not be subjected to external mechanical stress.
Minuses can also be considered the fact that the sheets do not fit very tightly to the walls, as a result of which a space is formed where domestic pests can appear.
If a small hole forms in dry plaster, it can be sealed with a special self-adhesive masking tape or cellulose construction putty.
If the hole is more than 50 mm, more effort will be needed to repair it.
From dry plaster, you will need to cut a patch twice as long and slightly narrower than the hole itself. Next, you will need to pierce the patch in the center and stretch the lace with a metal nail tied at the end through it. Then coat all edges of the patch with plaster or building filler and insert into hole . In this case, the lace must be pulled in order to firmly press the patch against the back of the plate. Then fill the resulting recess with plaster, and cut the lace.
At the end of the repair, apply a small layer of special plaster on the patch. Sprinkle with a little water with a brush and rub with a trowel.
If huge damage forms on the surface of dry plaster, it is necessary to cut it with a sharp knife to the nearest racks of the wall or ceiling. Then continue to cut to the middle of the racks and remove the damaged part of the sheet. Next, you need to saw off two wooden blocks, insert them between the posts and nail.
These will support the edges of the main slab and patch.
Then we cut out a patch of a certain size from dry plaster and nail it into place. Putty the joints, glue them with tape and wipe them with plaster on top.
Dry finishing plaster for exterior and interior walls requires proper maintenance. The problem is that certain voids remain between the surface of the walls and the drywall sheets.
With careless movements, the sheet can be pressed through, jammed, and it will have to be repaired.
Repair can be avoided by simply covering the sagging area with a small piece of drywall of the same thickness.
To do this, cut out the damaged part of the sheet. Then prepare a patch of a certain shape from drywall, remove all dust from the surface and moisten with water. Next, prepare a special gypsum paste or standard gypsum building dough.
After the mixture is applied to the repaired place.
Depending on the composition used, the surface dries in about an hour.After that, all seams are evenly filled with the same compound and leveled.
The damaged surface can also be repaired with gypsum mortar. To do this, it is necessary to apply the mixture to the place to be repaired.
The mortar must be leveled so that it is at the same level with the rest of the surface.
