What putty is better under the wallpaper

Putty is used to align the walls before finishing. There are different types of putty, which differ in composition, functions and the form of manufacture. To figure out which option is better suitable for wallpaper, consider the main types.

In the composition of putty are divided into:

Gypsum. This type has a low cost, well aligns the walls and does not have shrinkage. The only drawback can be called poor resistance to moisture. When applying plaster putty, it turns out a durable and non-glue surface, which is perfect for fitting and trimmed wallpaper.
Cement. This type is highlighted in excellent water resistance, but has a decent shrinkage and dries long. It can also be used under the wallpaper, but it is more suitable for the exterior decoration and premises with high humidity.
Polymer (acrylic). No shrinkage and make it possible to achieve high quality finished surface. After grinding, the effect of perfect smooth canvas is obtained. This type has a fragile structure and is more suitable for painting. It can be used under the wallpaper, but in density it is inferior to gypsum options.

The functions are distinguished by the following types of putty:

Starting. Used to pre-eliminate flaws. With their help, large irregularities are eliminated. Such a putty does not give a shrinkage, does not forms detachas and cracks. It is used to finish the walls under the wallpaper as the first layer. If the flaws are practically absent, the starting putty can not be used.
Finish. Hide small flaws and provide a smooth surface. They are applied to the walls as the second layer. When using thin wallpaper, it is important that the putty possessed high white. It also matters the strength of the composition so that during the subsequent repair wallpaper did not remove along with the finish layer.
Universal. This type combines the properties of the two previous options. It is used in cases where the wall has practically no flaws. The universal putty is more expensive, but in quality is inferior to starting and finishing coatings. Some experts recommend using finishing putty instead.

Putty on the form of manufacture:

Dry. Have low cost and long storage. But the prepared mixture has a little shelf life. In the manufacture of dry putty, it is necessary to carefully comply with the proportions. This type is excellent for the preparation of walls under the wake-up.
Ready. We are produced in the form of already prepared compositions and have a higher cost. They give a decent shrinkage, so they cannot be used for layers with a thickness of less than 2 mm. The shelf life is small. They are also suitable for wake-up, but more for exterior decoration.

Preparatory work. After selecting the most suitable option, it is necessary to prepare the walls to the spacious. Briefly consider the sequence of actions. Remove old wallpapers and apply primer. After two hours, make a re-layer. If necessary, after two hours, apply the third one. When it completely dry, plastered the walls. The layer of primer goes again. After performing these works, you can move to putty.

Putty. Apply the starting layer of putty in the horizontal direction from the angle. It follows the primer, the finish putty in the vertical direction and again the primer. It is worth noting that the finishing process should occur in a shock and an inseparable cycle. It is permissible to take breaks in 5-7 minutes and move on to the next wall. When the putty will be executed, take sandpaper and skill walls. This process is also called grinding or polishing. At the end, take a wet cloth and rinse it a wall. Immediately before salaling Start the walls again and let them dry. Everything is ready!

The appropriate type of putty will allow you to qualitatively prepare walls under the salable wallpaper, as well as avoid unpleasant surprises in the future. During the preparatory work to finish, focus on the sequence of items.
