Wall plastering for wallpapers - choose the right mix
Before you start leveling the surface, you need to decide on the putty mix, the range of which in the building markets is simply amazing. Two main types of this material are distinguished: a dry mix and already ready, made in the form of paste, they do not differ in quality. For this reason, the choice should be stopped on the option that will be most comfortable to deliver to the destination.
Let's consider the main types of putty mixes for the purpose:
- Leveling. In the event that the differences on the wall surface are of the order of 3 centimeters, you will definitely need this type of mixture, which is also called the "start".
Warning! Before applying a layer of putty, it is necessary to rid the surface of old materials, as well as thoroughly primer it!
- The second type of putty mixes was called "finish".It is applied when the walls are aligned with the previous type of mixture. As a rule, the "finish" layer is too small and is no more than 1-3 mm.
Tip! Before finishing the surface with a finishing layer of the mixture, it is necessary to check the surface for cracks appearing on it, then apply a layer of primer emulsion.
When should reinforcement mesh be used?
Putty for walls under wallpaper with the use of reinforcing mesh is necessary in the event that the surface is characterized by sharp and deep drops. The use of additional reinforcement will allow to increase the life of the walls several times without repeated intervention. In addition, the reinforcing mesh will eliminate the possibility of cracks, which will positively affect waterproofing and other mechanical damage.
Note! Fastening of the material takes place with the help of dowel-nails. The frequency of fastenings will depend on the surface structure. The more often you will attach the net, the more will be its tension, which will allow to apply a layer of finishing materials qualitatively!
It is worth noting that for the wall surfaces the grid is ideal, the cell size of which is 25x25 mm. In addition, using this element, you will significantly reduce the consumption of the putty mixture on the leveling of irregularities. If the walls are not suitable for leveling with special mixtures, then you can use good old drywall.
Process technology
Just note if you want to thoroughly study the process, such as wall plastering for wallpapers, video is available on our website. Thus, you can not only understand the technology of work, but also to hear the advice of specialists. Despite this, we offer you to get acquainted orally with the process algorithm:
- First you need to prepare the base of the walls for further processing. For this we get rid of old materials.
Tip! If previously there were wallpaper on the walls, then a small area is wetted with a roller, after which they can easily be removed with a spatula .
- When you have got rid of old materials, it is necessary to thoroughly surface the surface. Do not forget that the time for complete drying of the primer varies from 2 to 4 hours.
- Further it is possible to proceed safely to drawing of a starting layer шпаклёвочной to a mix. Usually this is done in 2-3 sets. Naturally, after each putty it is allowed to completely dry out.
Recommendation! For the convenience of work, the presented process should start from the top, gradually sinking down!
- When all the layers are applied and dried, the surface must be primed again. After it has dried out, we proceed to applying the finish layer of the mixture.
- After complete drying of the surface, all small defects must be sanded with sandpaper or special trowel, then the walls are primed again.
This completes the preparation for wallpaper gluing. You can safely proceed to the next stage of decorating the walls, but this is a completely different story!
