Repairs can be a pleasure for few people. It's easy to start and almost impossible to finish. Therefore, in all ages, mankind is looking for ways of least resistance in the processes of renewing its home. Sticking new wallpaper on old paper wallpaper, or on fiberglass or old paint, this is a very interesting idea, which is quite realizable, but when choosing this life hack it is worth considering all its pros and cons.
And also know how to determine if a similar technology is suitable for your conditions.
Wallpaper is a kind of outfit for a room. Fashionable wallpaper trends change as often as fashion in clothes. Just have time to change. So I re-pasted the wallpaper and seemed to refresh my life.
Arriving guests immediately make compliments to the rejuvenated apartments, and all that was required was a change of wallpaper.
But the process of updating itself is not to everyone's taste. There are a lot of hassles with stripping old walls and preparing walls.
Is it possible to stick wallpaper on old wallpaper? So is it possible to save time, lighten the work and embellish the home. And having done all the work yourself, you can also get economic benefits.
The modern market offers us the following types of wallpaper.
They are well known to everyone ... Paper wallpapers are glued easily, they are removed relatively easily.
They have a paper base and low strength.
It is very easy to glue if the surface is smooth and even.
Also made on the basis of paper.
Consist of intertwined silk threads. They are distinguished by good durability and the ability to wash them.
Designer wallpapers, however, are heavily impregnated with odors and dirt.
The most durable and dense.
Common in rooms with an increased risk of contamination (kitchens, hallways, baths).
Printed paintings, landscapes and other images - theme wallpaper .
Basically wallpaper craftsmen insist on the importance of the process of preparing the wall before gluing.
That is, you need to remove the outdated layer of wallpaper, remove the remnants of the used glue, level the surface, treat the wall with a primer and only then start applying new ones.
If in front of you is a wall with wallpaper that was glued using the above technology, and they have been perfectly preserved to this day, then you can still apply a little trick and glue the wallpaper without removing the old ones.
Advantages of technology
But the disadvantage is
Having compared the positive and negative aspects, we can conclude that such an experiment is quite risky and it is better not to apply it to expensive wallpaper.
Attention! The method is not applicable to wallpaper of the type: non-woven, vinyl, photo wallpaper and wallpaper with a relief pattern.
Only paper-based wallpaper can be glued in this way.
First, we check the surface for bubbles.
To do this, you just need to run your palm with slight pressure along the entire wall.
If it has cavities that are not glued, you will immediately feel it and in this case, the idea of pasting old wallpaper with new ones will have to be postponed ...
If the wall passes the test, then wipe it evenly with a damp sponge.
We are waiting for several hours, and then we look to see if the old glue swells from moisture. If successful, proceed to the next check.
Apply a couple of layers of primer to a small section of the wall and wait for it to dry. If in a day there are no places of deformation of the base, you can safely start work.
The surface is cleaned of dust with a cloth or vacuum cleaner.
Two coats of primer are applied, which in this case will be a mixture of wallpaper glue and white acrylic paint. You can add construction chalk if the composition lacks density.
Important! Primer coats should not be worn with a minimum of one hour drying between them.
After the primer has completely dried, the surface is sanded.
Do not immediately paste over all walls.
Better to try to put one strip of glue in the corners of the room and see what happens tomorrow. If in a day the wallpaper sheets will firmly adhere to the walls - feel free to proceed to the remaining surface.
Important! Sticking paper wallpaper on vinyl is possible if the covering film is removed from the latter. For this, the surface is passed with a needle roller and moistened. After soaking the substrate with a spatula, remove the entire film.
As a result, only the paper base remains on the wall.
From the above, it is clear that gluing new wallpaper onto old ones is quite acceptable, but it greatly limits the design options for the room, and after all, changing the coating on the walls is carried out precisely to improve the appearance of the room. And here this technology fundamentally cannot satisfy you.
If you are in doubt and cannot decide how you to paste the new wallpaper , make a choice in the benefit of correct and complete technology. So you definitely won't get a pig in a poke.
You can also look for a specialized forum and ask the craftsmen who have experience of such an update in their lives. Or watch video reviews.
Performing a high-quality wallpapering process is not so difficult, especially if you know a few secrets for removing the previous layer.
To simplify the work, you will need:
Its presence is not necessary, but it will greatly simplify and speed up the whole process.
The first step is to scratch the old wallpaper. The fact is that modern wallpaper is well enough protected from the effects of moisture on them, and it is possible to simplify their removal only by thoroughly moistening them first.
Therefore, creating scratches and various damages on the surface of the coating, we allow water to penetrate deep into the material and destroy their structure.
Tip! Remember to cover your furniture and floor before soaking the wallpaper.
Take care to protect outlets and electrical appliances from moisture.
The solution for destroying old wallpaper can be supplemented with any detergent, even crushed bars of soap. In addition, there are a huge number of specialized compositions on sale that are directly intended for peeling off the boring coating.
The solution should be applied two to three times at intervals of 15 minutes. As a result, the old wallpaper will come off with a slight movement of your hand and you will not have to scrub hard with a spatula.
If in front of you is a coating that was not glued to wallpaper glue, then you can remove it only by sanding a dry cloth.
