Can you still paste wallpaper on the wall plastered wall?

Now you don't need to scrape the wallpaper first, because the white wall can't stick the wallpaper, after the wall is painted with lime mortar, after drying, it is lumpy, but after a certain period of time, by the action of carbon dioxide and water in the air, it will produce powdery things (caCO3), this thing is not sticky, it will stick to the hand when rubbed by hand, if the wallpaper is pasted on such a material, with the drying and shrinkage of the wallpaper glue, it will not take long for the wallpaper to warp.

Therefore, it is necessary to shovel off the lime wall and use putty to base and level. Because the wall treated with putty powder or putty paste is still relatively easy to crack, now, better wall lining has been recognized by many people, and wall lining has more advantages than putty and is widely used.

In the past, white latex had to be painted before pasting wallpaper, but because of the poor environmental protection of white latex, it is no longer used now, basically a layer of base film is painted, because if you directly paste wallpaper, the adhesive force of the glue is very strong, and it is possible to pull off the base layer of the wall if you brush a layer of base film (or also called wallpaper mate), the base film can close the wall, waterproof and moisture-proof, increase the adhesion between the wall and the wallpaper, and wait for a day after brushing the wallpaper. Now there are some wallpaper glue already with the base film component, so there is no need to brush the base film alone, the putty is dry, and the wallpaper glue can be directly pasted with wallpaper.

Scrape a piece of the old wall in the repair, and then sand brushing a layer of base film can be pasted, and the new wall can be scraped at least 2 or more pieces in the sand brushing a layer of base film can be pasted.

Yes, but you have to do a good job of grassroots treatment, otherwise it's easy to fall off!

Latex paint can be applied to the wall, but it may not be secure.

In the pasting wallpaper is the choice of auxiliary materials is very important, in addition to ensuring its quality is no problem, but also to ensure the environmental performance of auxiliary materials, can not cause damage to the human body. Before pasting wallpaper, what is brushed on the wall is not a light varnish (varnish), but a colorless and odorless base film; The wallpaper adhesive is no longer wallpaper glue and white latex, but wallpaper glue is directly mixed with water; This ensures that there is no smell in the room where the wallpaper is being laid.

Pay attention to the problem. 1. The doors and windows of the room should be closed and dried in the shade after the wallpaper has just been paved. Because the room where the wallpaper has just been laid is ventilated immediately, it will cause the wallpaper to warp and bulge.

2. After 3 days after the wallpaper paving is finished, you should gently wipe off the remaining wallpaper glue at the seams of the wallpaper with a damp towel.

3. Wallpaper is more resistant to scrubbing, but it is not resistant to the bump of blunt objects, if you find a small surface damage, you can use similar color pigments or paints to remedy.

4. Non-concave and convex wallpaper, you only need to clean it with a feather duster on weekdays.

5. In case of wet weather, try to close the doors and windows as much as possible to prevent the water from being too heavy and the wallpaper will be damp.

The wall is made of latex paint, which itself is higher than the requirements of wallpaper, and small cracks and cracks must be scraped with putty, polished, and even used"Indeed cool cloth"cover, otherwise you will not achieve the desired effect;

The wallpaper wallpaper, when doing the base treatment, the requirements are not so high, because the wallpaper has a certain elasticity, plus the paper has regular or irregular textures, patterns, even the base of the wall is a little problematic is not harmful;

Therefore, it is very good to make a latex paint wall and then paste the wallpaper. In addition, the latex paint itself has the functions of moisture-proof, mildew-proof, and brush-resistant, so there is no need to worry about what adverse reactions the latex paint will have on the wallpaper after pasting the wallpaper;

However, the old wall that has been used cannot be directly wallpapered; It is necessary to do the following work:

You can apply wallpaper or latex paint, but you still have to do some work before. It needs someone who specializes in wallpapering to do it.

Sticking wallpaper needs to scrape the wall skin to keep the wall flat and more convenient to paste wallpaper, and the specific steps for sticking wallpaper are as follows:

1. Wall repair.

Before pasting wallpaper, clean the wall. Clean up the original paint, wallpaper or nails and other attachments on the wall, shovel off the wall if there are cracks and peels, and repair the potholes. After the wall is cleaned and repaired, proceed to the next step.

2. Wall polishing.

Brush the walls with alkyd varnish, and when they are dry, start scraping putty and sanding the walls. After the putty is fully dried, polish the wall with sandpaper with a suitable number of meshes, grind off the surface protrusions, and the wall can be sealed after the wall becomes flat and smooth, so as to prevent the wall from absorbing wallpaper glue.

3. Wallpaper cutting.

Lay the wallpaper on the ground for cutting, and the adjacent wallpaper should match the color and texture to keep the pattern flat and consistent. Brush the wallpaper glue on the wall, and then paste the wallpaper one by one, and sweep out the bubbles between the wallpaper and the wall with a plastic plate to ensure that the wallpaper is firmly laid.

Yes, but wallpaper that has not been painted with latex paint will work better. Therefore, I personally recommend that you do not stick wallpaper on latex paint.

Yes, generally speaking, the new wall can be painted directly, if it is an old wall, it is recommended to use a wire brush to polish it slightly, then brush the wallpaper primer (Shierz), and finally paste the wallpaper.

The wallpaper is torn off and then painted, which can be roughly divided into three steps.

Step 1: Tear off the wallpaper and remove the adhesive.

Wallpaper is generally composed of three layers, the bottom layer is the base film, the middle is the wallpaper glue, and the outermost layer is the wallpaper.

After we remove the wallpaper, we must also remove the residual wallpaper glue, and then observe the state of the base film and the wall base.

Step 2: Check the base film and confirm the status of the base wall.

Generally speaking: the base film has a certain protective effect on the base layer (thick leveling and fine leveling, such as putty), but with the change of time, this protective effect gradually deteriorates, and it may be found that the base layer has serious peeling and cracking after eradicating the glue, so it is necessary to shovel the wall and redecorate. For specific steps, you can refer to the eight steps of wall decoration (included in the "Wall Red Book" I wrote).

If the quality of the base layer is relatively good and there is no peeling and cracking, then there is no need to eradicate and redecorate. You can go straight to step three.

Step 3: Apply latex paint.

Latex paint is generally 1 primer and 2 topcoats.

For this kind of wallpaper renovation wall, the primer is a must.

Let's say more: to do the third step, there are many decorative layers to choose from, you can re-paste the wallpaper, you can also paint, you can also do diatom mud, you can choose according to your needs.
