Advantages and disadvantages of drywall
With gypsum cardboard, it is best to align very curved walls that have hollows and protuberances a few centimeters. It happens also( especially in private homes) that the wall is not only uneven, but not even strictly vertical. In this case, it is much more convenient and quicker to use gypsum cardboard than to try to achieve ideal surface parameters with the help of a stucco.
With strong "inconsistencies" of slabs, and they sometimes reach 5-8 centimeters, it is also much easier to do alignment with GKL.Another plus - the possibility of creating with gypsum cardboard of various designs and raznovysotnyh ceilings, as well as the ease of concealment of wiring and various communications.
The drawbacks of using gypsum plasterboard sheets include the following:
- the useful area of the room sneaks( on an area of 20 sq. M - about 0.9 meters);
- , when leveling the outer wall, it is possible to break the thermal insulation, followed by the formation of dampness and mold on the inside;
- on a drywall wall you can not hang a shelf or a heavy picture, and from a strong impact this material can fail;
- between the GCR and the wall, even if the space is filled with heat-insulating material, rodents can start. And thus not only irritate your fuss, but also damage communication.
In order not to lose extra meters, sheets of HK can be glued directly to the wall on a perlix. But this option is possible only with small irregularities.
In any case, consider that using plasterboard instead of plaster, it still needs to be covered with a layer of finishing putty with subsequent polishing. Plaster of walls from plasterboard eliminates the problems that you will face in the future. When there is a desire to re-paste the wallpaper, there will be a difficulty - the old canvas will be removed together with the outer shell of the gypsum board - cardboard.
Advantages and disadvantages of plastering
Whatever is said about modern finishing materials, but the most reliable and durable way of leveling walls and ceiling is lime or cement-sand plaster. It has only two drawbacks - a very high cost of work, which you yourself can hardly produce qualitatively, and a long time of drying.
Therefore, if it is a question of which material to use - plasterboard or plaster, then it is more necessary to talk about gypsum plaster or starting filler with further coating of walls and ceiling with a thin layer of finish putty.
Such plaster has a number of advantages over plasterboard. Firstly, you will lose the minimum amount of useful area of the room. Secondly, you can freely hammer a nail into the wall, hang a shelf or a heavy picture, without fearing that it will destroy it. And, thirdly, with small unevennesses it is definitely more profitable to plaster.
Cons of use of plaster:
- for plastering there will be a lot of dust and dirt;
- it is necessary to make stitches and lay all communications in them;
- it is desirable( though it is not necessary) to fix the grid on the walls before starting the work, and this entails additional time and expenses;
- is much slower to move forward repairs, because at one time you will never get a perfectly flat wall;
- the need to rub the walls with sandpaper or mesh, followed by applying the finish putty.
What is cheaper than drywall or plaster?
If you disassemble the question of what is cheaper than drywall or plaster, then you need to consider a number of items .It is necessary not only to estimate the geometry of the walls and the approximate number of materials, but also to calculate the time required for finishing works. And only after that, calculate the repair budget. In addition, it is worth remembering that if plastering works can be done by one person, then installation of the GKL is performed with an assistant, which means that an additional expense item may appear - payment for the worker's services.
Given all of the above, we can draw the following conclusion. Provided that the walls need only a little fix, definitely plaster will cost less. But with very uneven walls and ceilings, it may be cheaper to finish with plasterboard. Therefore, the final choice should be made by you, weighing the advantages and disadvantages of each method.
