Repair is a very time-consuming task requiring rather large financial investments. Each person, updating the interior of his home, is trying in every possible way to save money, so many are interested in the question of whether it is possible to glue wallpaper on drywall without putty on the primer. This and much more will be discussed later.
Underwater rocks
Construction practice allows sticking wallpaper on drywall, however, in order for the result of the work done to be satisfactory, the following nuances should be taken into account:
- When gluing too thin wallpaper, joints between the sheets of drywall will appear through them, which will spoil the appearance of the room.
- Over time, the color of thin wallpapers can acquire a green tint, which will also adversely affect interior design.
- The glue penetrates very deeply into the GCR, as a result of which it will be practically impossible to remove wallpaper from the wall in the future.
So, the answer to the question of whether it is possible to glue wallpaper on drywall without putty is positive, however, as you have already seen, if you do not take into account the above factors, the joy of the repair may not last long. The thing is that the puttying of the walls allows you to hide irregularities and various defects that can be noticeable even with the naked eye. And if you stick expensive wallpapers, then even the smallest defect can completely reduce all your efforts.
What you need to know before wallpapering?
If you are planning a repair in a room in which the wallpaper is already pasted, then the first thing they need to be removed. This can be done very easily and quickly using special tools designed to remove glue. They are sold in the form of powders that are diluted in a certain amount of water. The resulting mixture is applied to the walls for approximately 10 minutes, after which the old wallpaper is quite easily removed with a spatula.
If you are interested in whether it is possible to glue wallpaper directly on drywall, but there are excess putty or any defects on the walls, then the first thing to do is to put the drywall in order and eliminate all bumps and cracks. In addition, it is recommended that the walls be primed in order to improve the adhesion of the wallpaper to the wall. After the primer dries, you need to inspect the perimeter of the wall near the floor and ceiling for bumps. If they are found, then they should be wiped. If this is not done, then after installing skirting boards and baguettes, these irregularities will be very noticeable. In the presence of defects, grouting is allowed not to be carried out if you plan to glue thick wallpaper, since they mask well the unevenness of the walls.
Preparatory stage
Before answering the question of whether it is possible to glue wallpaper directly on drywall, and how to do it, you must first touch on the topic of preliminary preparation of walls for the process of wallpapering. The first step is to perform a visual inspection of the walls for any defects: bumps, cracks, crevices, voids and other defects. The joints of the gypsum board must be glued with a special tape, thanks to which the sheets of drywall can expand freely, and will not crack over time.
After all defects have been removed, the walls are putty. This work should be done in one go, so that after the solution has dried, the walls are perfectly even. It takes at least 24 hours to fully dry the building mixture at the optimum temperature and humidity in the room.
Tips and tricks for choosing putty
Without the right choice of putty, it is impossible to answer the question of whether it is possible to glue wallpaper on drywall. When buying a mixture, you should pay great attention to the release date, shelf life, as well as the type of mixture, and under what conditions it can be used.
If there are small defects on the walls, the size of which does not exceed 50 millimeters, then you can safely use a mixture intended for finishing work. If cracks and crevices are up to 25 mm, then in this case starting putty will help to solve the problem. At the same time, it is better not to try to save money by buying a cheap and low-quality mixture, since, as practice shows, the result simply does not live up to expectations.
What is the best way to putty walls?
So, we have already figured out whether it is possible to glue wallpaper on drywall, and what preparatory work should be done before that. In order for everything to turn out efficiently and beautifully, it is very important to properly putty the walls. These works are carried out in three stages: first, the first layer of the building mixture is applied, and after it dries, the second. When the second layer is completely dry, then the finish is applied, for which you need to use a putty of a more liquid consistency. This will not only hide even the smallest defects, but also make the walls perfectly smooth.
In this case, it is necessary that each new layer overlap the previous one by approximately 50 centimeters. In addition, after drying, each layer must be wiped with sandpaper.
Masking joints between drywall boards
You are interested in the question of whether it is possible to glue wallpaper on drywall, and what to do next, after the puttying of the walls is completed? At the next stage, you need to mask the joints between the drywall boards. The first step is to trim the corners of the plates on both sides at an angle of 45 degrees. This will make the transitions smoother and invisible.
A special mixture is used to grout joints, which can be purchased at any building materials store. The powder is diluted in water in compliance with the proportions indicated by the manufacturer on the package. Apply the mixture to the joints between the sheets of drywall must be very careful, evenly distributing it with a spatula along the entire length. Do not use too much mixture, because otherwise, after drying, tubercles will be visible that will spoil the appearance of the interior after wallpapering.
Disguise self-tapping screws
Is it possible to glue wallpaper on drywall? The answer is yes! However, it is important to understand that drywall sheets are attached using self-tapping screws, the caps of which will appear through the wallpaper, spoiling the whole view. Therefore, they should also be masked. To do this, it is necessary to screw the screws a little deeper into the drywall so that they are recessed by about one millimeter, after which the holes are sealed with putty. If cracks have started at the place of screwing in the screw, then they need to be glued with a reinforcing tape. It will prevent further cracking.
If you especially do not want to mess with screws and cover them with mortar, then they are treated with a special solution before screwing into drywall, and the screwing points are glued with a docking and reinforcing tape. When all these works are completed, the walls are puttied, and when the solution dries, you can begin to begin further work.
Wallpapering without puttying the walls
Many people are interested in whether it is possible to glue non-woven wallcoverings on drywall without first filling the walls. Builders admit this, however, so that the adhesion of the wallpaper to the wall is reliable, you can start gluing no earlier than 24 hours after all the defects have been eliminated and the mortar has completely dried.
The following recommendations are also recommended:
- Before wallpapering, the wall must be cleaned of dust and dirt.
- When priming the walls, it is recommended to add a dye to the mixture, the color of which matches the color of drywall. This will achieve a uniform tone.
- It is better to dilute glue in a clean container, which was not used for the preparation of other mortar. If dust or any other foreign substances gets into the glue, then its quality will deteriorate very much.
- When sticking thin wallpaper from drywall, all inscriptions and logos should be removed so that they do not shine through.
- If the wallpaper was not glued evenly or a gap formed between them, then they should be removed from the wall, while the glue has not yet dried, and re-glued.
Adhering to these simple tips, you can perform high-quality repairs, and the question of whether it is possible to glue liquid wallpaper on drywall will no longer bother you.
Conclusion
Sticking wallpaper on drywall without pre-wall decoration can save on the purchase of building materials and reduce repair costs. However, it should be borne in mind that the lack of a primer reduces the protection of walls and materials from moisture and mechanical damage, therefore, in order not to regret in the future, you must carefully weigh the pros and cons.
