How to prepare walls for liquid wallpaper: work procedure, whether it is necessary to putty

Preparing walls for liquid wallpaper begins with removing the previous base, treating with putty and primer. Moreover, it is better to prepare the mixture in advance, because it matures within several days. Instructions for processing and mixing the composition can be found in the presented article.

Is putty necessary?

Liquid wallpaper is a decorative plaster based on organic and mineral components (lime, cellulose, acrylic, silicate and others). This composition can be applied to almost any surface.

But unlike ordinary plaster, decorative plaster is not intended for leveling walls. It should only be applied to a well-prepared surface. The procedure for preparing walls for liquid wallpaper involves several steps:

1. Removing the old base.
2. Dismantling hard parts, nails.
3. Alignment of walls.
4. Applying putty.
5. Padding.

If you figure out how to prepare walls for liquid wallpaper, you can take advantage of all the advantages of this type of finishing. They are easy to apply, do not crack even after shrinking at home, do not crumble, and most importantly, they look very beautiful. There are no disadvantages as such, but it is important to align the walls correctly - otherwise it will not be possible to achieve a high-quality result.

The procedure for preparing walls

Preparation includes several stages.As a rule, work begins after preliminary removal of the old layer and thorough cleaning. But sometimes you can apply liquid wallpaper to paint. This method is acceptable if the surface is intact, does not flake, and at the same time matches the color. You need to understand that decorative wallpaper is applied in a thin layer and will not be able to completely cover the old background.

Preparing walls for applying liquid wallpaper looks like this:

1. Remove old paint and plaster. Carefully remove the remains of the previous material - this stage is very important, so it is better to try to prepare the surface well.
2. Remove protruding nails and other hard elements.
3. If some communications, for example, pipes, cannot be removed, put putty on top with a layer of 2 mm. Another option for preparing liquid wallpaper for work is to coat it with an oil paint composition.
4. Level the walls and eliminate depressions using gypsum-based putty. If there are plasterboard partitions, they are also treated with putty. Moreover, the composition is placed not only on the surfaces themselves, but also on the joints between the plates.
5. When the surface is already prepared and leveled, preparing the walls for liquid wallpaper is simplified. Now all that remains is to treat them with a primer. It is better to buy a regular deep-acting composition. Apply it in several layers, allowing the previous one to dry for 3-4 hours.
6. Then, when the last layer of primer has dried, they apply putty again. But for this they use not standard, but special putty specifically for liquid wallpaper. This is a special composition of thick consistency that smoothes the wall well for further processing. If it is not available, you can use regular white water-based paint. Another option is to cover it with facade paint.

Preparing liquid wallpaper

Liquid wallpaper also needs preparation. Moreover, the composition matures for quite a long time - about 10-12 hours. Therefore, it is better to start in advance, even while treating the walls with a primer. The preparation technology depends on the packaging features. In some cases, all components are packed in different bags - then they are poured into water one by one. They often sell ready-made formulations that just need to be diluted with water according to the instructions:

1. Warm, but not hot water is poured into the container in the volume specified in the description.
2. The mixture is introduced into it, diluting each package separately, or adding the entire composition at once.
3. Stir the mixture yourself, i.e. manually, without the use of special equipment. This is the easiest way to achieve uniformity when working with relatively small volumes. Although, if the manufacturer allows the use of a drill with a mixer attachment and indicates this in the instructions, you can use this method.
4. Preparing the walls before applying liquid wallpaper necessarily involves aging the mixture for several hours - it is better to let it sit for up to 12. It is important to follow the instructions in the instructions. Due to swelling, the glue becomes soft and securely binds the base.
5. When everything is ready, you can stir again. At this point, the preparation of concrete walls for liquid wallpaper will already be completed. It is better to immediately start applying the composition, because standing for too long is also undesirable.

From this review it is clear whether it is necessary to putty the walls under liquid wallpaper. This is a very important stage, which cannot be avoided. Moreover, the composition itself should also be prepared in advance. Then it is applied to the wall with a spatula and distributed evenly. Thanks to this, the walls under liquid wallpaper will turn out beautiful and almost perfectly smooth.
