When it comes to remodeling your home, there are always a lot of questions. For example, how to install drywall correctly, whether it can be done on your own, whether it needs to be primed and what kind of putty to buy. Drywall itself is smooth and even, but it comes in a certain size, so it is impossible to avoid joints between them. These irregularities, as well as peeking screw heads, must be repaired with putty.
This work is not difficult, but it takes a lot of time. First you need to decide on putty. Putty is a white powdery substance that is used in construction. With the help of this material, smooth walls, floors and ceilings are created. On top of the dried putty, you can apply paint or glue wallpaper.

In large hardware stores, there is usually a huge selection of everything - not only putties, but also other repair tools. Therefore, it is very easy to make a mistake and buy not quite what you need. How to choose the right putty? First you need to understand what it is.
Firstly, among the many types of putties, you will immediately understand that not all are suitable for your purposes. There are putties for ceilings and floors, there are for covering cracks and chips, and there are generally purely decorative ones that will not fulfill either the first or second task by 100%.
Secondly, based on the material that is contained in the base of the putty, gypsum, acrylic and cement mixtures are isolated.
Putties are sold in dry and liquid form. Dry mixtures must be diluted with water according to the instructions. Diluted putty should be used immediately, but dry putty can be stored for a long time, which is its advantage. Putties in buckets do not require any additional manipulations, they are completely ready for use. They are stored longer than diluted dry mixes, but, nevertheless, they cannot compete in terms of storage time with dry mixes.
There are also starting, finishing and universal putties. The starting one is used for preliminary alignment of the walls. It perfectly copes with its task, but its appearance is rather rough, so it is necessary to use finishing putty - an additional element that makes the wall or ceiling smooth and uniform. Universal putty can be used as a substitute for starting and finishing with slight surface irregularities.
For drywall, gypsum plaster is best. Polymer has also proven itself well. If you can afford it for the price range, then you can take it.

It is a universal mixture for puttying. Made from high quality gypsum. Great for sealing drywall joints, for leveling uneven walls and ceilings. The price for 20 kg of dry mix is 365 rubles.
To perform quality work, you need to prepare the tools. Be prepared that you will need two spatulas - wide and narrow, roller, brush, knife, sandpaper. To seal the seams, you will need a special mesh, popularly referred to as "sickle". You also need the putty mixture itself.
Before puttying, the surface must be treated with a primer. The seams are treated with a primer, and then filled with putty. While the putty has not yet dried, you must immediately lay the reinforcing tape. Sealing ends with additional application of leveling material.
It is necessary to completely fill the seams of gypsum boards, but at the same time level the putty so that a layer of the minimum thickness is obtained. When everything dries well, the areas with putty are treated with sandpaper to level the surface.
Wall corners require special attention. The inner corner is glued with a reinforcing network, while its half is located literally at the junction of the walls. If an ordinary sickle is used, then PVA glue is applied to its plane with a brush, then it is attached and the reverse side is smeared with glue.
After the glue has dried, a starting putty is applied to both sides of the corner with a simple spatula. The layer must not be very thick, but sufficient to cover the mesh. The applied putty is leveled with an angular spatula. When the surface dries, it is necessary to process it with sandpaper in order to remove all bulges and sagging.
Finishing the outer corners of the plasterboard walls also has its own specifics.
A layer of starting putty is applied to both sides of the joint. The layer thickness should not be large. The perforated corner is superimposed over the machined corner and pressed down so that the putty comes out through the holes. Next, you need to level the putty, for which you will most likely need to apply more mixtures. At the end, it is necessary to remove excess putty that has not yet hardened.
After drying, the surface is also treated with sandpaper. The final stage of finishing the corners is carried out in the process of final puttying of the walls. When finishing the outer corner with a plastic corner, it is applied to the corner and fastened with a construction stapler. Putty is applied to both sides of the corner and leveled with a narrow spatula. All excess putty at the end of the corner must be removed before it dries. At the end, when the mixture dries, you need to check the surface for irregularities and, if necessary, level with sandpaper.
When all the seams and corners are sealed, they proceed to puttying the entire area of \u200b\u200bgypsum plasterboard. This is done so that the entire area is absolutely flat, the drywall sheets do not bend anywhere. This is especially important if wallpaper or paint is applied to drywall. To finish the wall or ceiling, all irregularities are carefully rubbed with sandpaper.
To make it easier to apply the mixture over a large area, a wide spatula is used. The putty layer should be thin and even. If wallpaper is glued to the walls, then there will be three layers of putty in total: two for the drywall joints and one for the entire surface. For painting, a more thorough study of the entire surface is needed, so here you need to do more for one layer - re-treat the entire drywall area.
Typically, the consumption of putty depends on the scale of the work and on the number of defects that need to be repaired. Often, workers are guided by such an indicator: 1 kg of dry gypsum putty per 1 square meter. Of course, it is better to take with a small margin. And be sure to follow the application technique.
It is necessary to dilute the dry mixture in such an amount that it lasts for less than half an hour. If more time passes, then the putty will simply dry out and there will be some sense from it. It is also not recommended to redo the work already done, since you can make the surface even more uneven, as well as reduce the durability of the putty.
