Features
Drywall has many positives:
- No assembly complexity.
- Eco-friendly material.
- Full protection against heat escape.
- Noise isolation.
- Versatility.
This is the main thing that makes every master stand out.
What are the most common species?
On the market you can find different types, with their own characteristics. The division is based on GOST:
- GKL drywall is a standard look, without additives. Visually with a gray surface, most often used in finishing work. Becomes a good sound barrier, suitable for mounting false ceilings. Do not confuse it with GVL - this type is much stronger and comes with additives.
- GKLV - moisture resistant sheets. Oftenappear in rooms with high humidity. Despite this, special protective masses are used for a long service life. They cover the surface.
- GKLO - fire-resistant look. To avoid confusion, each sheet is covered in its own color. The composition of the reinforcing substances, which are a barrier to fire. In rooms where fire safety requirements are high, it is suitable for decoration.
- GKLVO - has high moisture and fire resistance. The scope is different, depending on the characteristics.
GKL drywall is considered the most popular on the market. A variety of finishes are made from it, even a person without much experience quickly copes with the task.
What is characteristic of the material?
Standard material sheet is rectangular. Available sizes:
- From 600 to 1200 is the width in mm.
- 2000-4000 mm - length.
- 6.5-12.5mm thickness.
Before you start finishing, full calculations are made. GKL drywall 12.5 mm thick is the largest, and it is difficult to create unusual designs from it. Builders divide the material into ceiling and wall, depending on the size. In addition, the price also differs depending on the thickness.
For the installation of arches and ceilings, such dimensions are most often used - 1200 by 3000 by 6.5 mm. It is plastic, and smooth lines come out without problems. Wall decoration and the creation of partitions come from a more durable material.
Drywall "Knauf"GKL
For repairs in a house or any other room, it is good to take durable material or ready-made parts as a basis. A striking confirmation of such work is the Knauf drywall. It is used for interior decoration. This is:
- Flat surface finish.
- Working on false ceilings, in several levels.
- Creating arches, niches, partitions.
- Decoration.
Such drywall GKL GOST must comply. To create a surface, durable cardboard is used, which is rounded at the ends. Inside there is gypsum with additives for strength. Obvious positive aspects are a low level of ignition, good noise protection. To create it, no chemical fillers are taken. The material is completely environmentally friendly. Also, the reviews say that Knauf moisture-resistant sheets are not subject to rotting and mold formation.
The length of this material is from 2 to 4 meters, width is from 6.5 to 24 mm. The main disadvantage is that the weight of such a sheet is 40 kilograms, which means that it is difficult to install it yourself. Depending on the place of attachment, GKL UK drywall is divided into:
- Wall - fixed in a vertical position, maximum thickness.
- Ceiling - the price indicator is lower than the first one. Used for suspended ceiling installation, weight less than 30 kilograms.
- Arched - its thickness is average (up to 6 mm), which allows you to create uneven structures. To do this, it is pre-moistened, made the desired shape and dried. Only after that they are mounted in the right place.
The construction process has its ownpeculiarities. Despite the ease of implementation, many can make mistakes when working with GCR drywall. The top layer should be carefully sawn so that the internal composition does not spill out. But after creating one sheet of the desired size, everything goes on simply.
Types of Drywall
All building material is conditionally divided into several variations, for ease of use and purchase. The filler is considered important, from this the material has several types. It is moisture-proof, waterproof, regular, flame retardant. This makes it easier to make a choice depending on the purpose of the finishing work.
Regular and waterproof
The first cannot be used in rooms with high humidity, which cannot be said about the second. If the usual one gets wet, then its shape changes, its strength is lost. As a result, mold and fungus form. Moisture resistant "Knauf" is one of the best options for finishing the bathroom and bathroom. A special composition is applied to the surface, which prevents moisture from penetrating inside and spoiling the surface. Most often, it becomes the first finishing layer, and then any tile is applied.
Flame retardant and waterproof
There are rooms where other finishes are simply not available. For the price, these sheets are more expensive than the usual type, the dimensions are the same. When a fire breaks out, the flame stops.
In any case, each type finds its scope. Drywall is actively used not only in new houses and apartments for decoration, but also during major repairs inold building.
How to buy?
The amount of material is preliminarily calculated depending on the finishing area. It is worth deciding on the width and length. The weight is large, so it will be difficult to mount alone. It is also immediately necessary to prepare a tool for cutting. More often use electric jigsaws, it's faster. Gypsum plasterboard "Knauf" GKL is considered one of the most demanded on the market, for its qualities and long-term performance.
What types are equally good?
Since the finishing material is in demand, there are many offers on the market. Drywall GKL "Volma" has the following main types:
- Regular.
- Moisture resistant.
- Flame retardant.
- Water and fire resistant.
The sizes are most often standard, but if the client wishes, many manufacturers work on personal orders. GKL drywall is fire resistant, and all others of this brand have recessed edges, which allows you to completely hide the joint after finishing with putty. Sometimes such conditions are required for individual finishing. In order not to be mistaken, any of the types has its own marking:
- Standard - gray front and back with blue markings.
- Moisture resistant. The front is green and the back is grey. Marking blue.
- Flame retardant. The front is pink and the back is grey. The label is red.
- Water and fire resistant. The front side is pink, the reverse side is green. The label is black.
In addition, conventions are used. It's easier to make a choiceerror-free and purchase the desired product. Not always a person without experience can accurately make some calculations.
Specifications for comparison
To understand what is at stake, you need to know the distinctive features. GKL drywall sheets are not produced according to GOST, but in compliance with TU. But this does not affect the quality of the material in any way, but on the contrary, it gives the best indicators - strength, density, reliability. In the production process, non-standard components are used - sugar and starch. Their task is to increase the level of adhesion of the main surface with the internal filler.
Knowing the characteristics of each sheet, it is already easier to make your choice. The Volma brand does not have any special differences from other manufacturers, so it is easy to work with sheets. The only exception is the need to create a deep cut, otherwise the edge may break, breaking the evenness.
To make the surface perfectly smooth, additional grouting is required. To do this, putty is used, otherwise the lining will be of poor quality. Moisture-resistant GKL drywall is also subjected to seam masking, otherwise moisture will seep inside. And then mold can develop in the gaps, which is not very good.
How to work with trim?
This finishing material is often used. Knowing the execution technique, it is easy to create a smooth surface of walls or ceilings in a short time. And most importantly, that in the process of work does not appear dirt and dust. Although some inexperienced people may make mistakes in the process,which leads to breakage of the sheet, and hence the rash of gypsum. Need to use sharp cutting tools. Installation of drywall plasterboard is not very difficult, but the surface is pre-prepared.
If the cultivated area is with large differences, then without a frame it will not be possible to implement the project. Some believe that such a finish takes centimeters of space. For this, metal parts or wood are used, but the first option is more reliable and durable.
The step between the selected material depends on the brand of drywall sheets. This is most often 600 or 400 mm, although everyone decides this issue depending on the area of \u200b\u200bfinishing, its quality and other things. Ordinary self-tapping screws are quite suitable for fastening. But they are worth tossing. Be careful as applying too much pressure to the tool may break the sheet.
A common problem is the movement of the sheet after fastening, as well as the sprinkling of the edge. To avoid this, you need to properly mount the sheet - the joints must coincide with the central axis of the supporting profiles. This is not difficult to do, the step is carefully calculated, after which the step of fixing the metal or wood is preliminarily determined.
To cut a sheet, everyone uses an accessible and convenient tool for themselves. But most often it is a construction knife. Perform a double cut from the front and back sides, then a break is made over the entire required area. After each joint is hidden under the putty and the self-tapping screws are deepened. Then the entire work surface is processedprimer mixture. Next is the final front finish.
It is not always necessary to create a framework. When the surface of the wall and ceiling is perfectly flat, then there is no need to mount too much. Drywall is installed on the adhesive composition. Here you need to acquire a quality composition, otherwise the work will be in vain. Also, any surface is treated with compounds to increase adhesion. Before fixing the building sheets, the reverse surface is also covered with a primer.
Under what finish is drywall mounted?
As already noted, drywall is a unique material that can serve as both an independent finish and a rough finish. What is suitable for further fixation:
- Ceramic tiles.
- Wallpaper.
- Compositions for whitewashing and coloring.
- Creating partitions and more.
In any case, all work must be done in a certain sequence so that the sheets are securely fastened.
People's reviews of drywall sheets are very different. It all depends on the chosen manufacturer. The bulk of the craftsmen believe that it is necessary to use those materials that are produced in accordance with the requirements of GOST. Specifications give a number of errors, which affects the reliability and duration of operation.
An important indicator is storage at the point of sale. With the wrong approach, oxen appear on the surface, which will further affect the finish. In any case, finishing work withdrywall sheets are considered high quality and durable.
Conclusion
So, we have considered what drywall is. As you can see, this is a very practical material that can be used in various fields. The cost of drywall sheets is small, which makes this material very popular in the market.
