The need to use a primer for drywall under the wallpaper

The need to use a primer for drywall under the wallpaper

Do I need to prime the drywall under the wallpaper?The question that everyone must ask, who once was engaged in repair.

As a universal finishing material, drywall and even impregnated polymer additives, ensuring stable grip gypsum mass, from the outside only cardboard.

And as the paper is very easy to damage, there is no consensus about the need for priming drywall before applying wallpaper, whether primed drywall putty before and whether we should be primed before tiling.

soil Does drywall?

Opinions differ on this issue.

Some believe that the drywall primer is needed.Others propose to handle only seams that are plastered.Third, generally believe that this material does not need treatment.

However, many experts believe that a primer is needed before pasting wallpaper, and before the filler.

Since impregnation improves the paperboard adhesion to other materials, plasterboard gives added strength, thus increasing its service life, the wallpaper will be better to hold on.

bright wallpaper will not shine.Also, you can easily remove them when the time comes to change the wallpaper.

Therefore, the question "Do drywall soil?", We can clearly say "Yes".

The prime?

answer to the question "Do drywall soil?" Once the new wonder "What primed, the primer which to choose?".

Currently selected primer is easy.Enough to pay attention to what works the primer, internal or external.

for decoration is to abandon the primer used for the exterior, as it may contain toxic substances.

most frequently in the work of plasterboard used acrylic primer, though there are also other types.

Primers for drywall

would be preferable if used acrylic primer represented in the finished form, but not in the form of the composition, from which it is necessary to prepare the working mixture.

In the latter case it is necessary to strictly comply with the instructions to the primer has not turned too liquid, or vice versa, too thick.

Violation cooking recipe primer may adversely affect the surface to be treated, and thus complicate the preparatory part before pasting wallpaper, painting walls or laying tiles.

sequence drywall work training under the wallpaper

Preparing the drywall before pasting wallpaper includes five main components:

  • initial priming;
  • treatment of joints;
  • leveling putty;
  • grinding;
  • re-priming.

dwell at each step in detail.

Initial priming

Priming the drywall, not only improves the adhesion, but also protects it from the development of mold and mildew.Therefore, the first step will be to complete processing of the entire surface.

solution was applied with a brush or roller over the entire surface uniformly.Damage primer layer usually dries up to 24 hours, to know exactly how much can be instructions on it.

Roller and brush

joints Processing

very important stage in the preparation of the drywall.

joints are sealed using armirovochnoy paper or fine mesh - serpyanku.This prevents occurrence of cracks on the spot welds.Top

applied putty, level the surface and remove any excess with sandpaper.

Mesh for joints

Alignment spackling

surface to fit any work finish or fine-grained putty.Sometimes ready-made, and as a dry mix.

If you use dry, do not forget to observe the basic rules when mixing the solution - added to the water putty, and not vice versa, as a mixture of fill depends on the brand, usually specified in the instructions.

For application use a wide and a narrow spatula, respectively, for uniform stretching and laying and removal of surpluses.


spackling fill the entire space of plasterboard, plaster evenly stretching.It is better to lead from the edges toward the center.

Impose two layers, not forgetting the polishing and removal of dust from the surface between them.Do not forget also that the first coat dries, and only then polished.


start sanding the surface only after the plaster dries.How much time it takes?Normally dry day.

used for grinding coarse and fine sandpaper.First grind coarse sandpaper, then brought to the surface a fine ideal.

drywall Sanding

Repeated priming

Processing the entire surface of the drywall.

Overlay primer may be in one or two coats.Again, do not forget also that before the second layer of primer, the surface must be dry.

How primer dries you can not say exactly, depending on its type - from 5 to 24 hours.

After completing all the steps we can glue the wallpaper or start painting the walls.

wall Primer

priming before painting

process drywall primer prior to painting described above.

Particular attention should be paid to the processing of joints, aligning them with the drywall surface and grout surfaces before re-priming.

It must be perfectly smooth, as the colored layer will transfer all of its flaws and errors.

Laying tiles

Plasterboard line the walls not only in residential areas.

They can sheathe the walls and the bathrooms, although in this case it is necessary to use a moisture-resistant gypsum board, painted in green and not mounted on wooden and metal frame.

rigid foundation needed to avoid deformation.

Before laying tiles on gypsum board it is necessary to prepare the same way as before pasting wallpaper or painting.For the sealing of joints in this case use is not putty, and tile adhesive.

soil the entire surface and wait for it to dry.

Attention!Laying tile can be made only when the whole treated drywall primer has dried.

How dry primer: it is dependent on the humidity and temperature of the room bathroom.

While drying the surface, better calculate the tiles, starting with the top row.It is made only from whole panels.

Measure ranks, not forgetting to take into account the thickness of the seam (it corresponds to the size of the cushioning of the cross), prepare the stops for tile and tile adhesive.

adhesive can be applied at both the tile and on the surface itself.

Thanks to a flat surface prepared drywall, tiling becomes quite an easy process, but do not neglect the level.


To the wall did not work ladder, it is necessary to control the level of both the faces and in the plane.

joint width will be less noticeable if you correctly pick up the gasket cross.The most common use of 3 mm.

avoid kinks tiles, when it is possible to use a conventional cutting glass cutter.After the tile lines quickly and easily break in two.

After tiling soft rubber spatula makes grout joints.Excess mixture is removed from the surface of the plates with a damp cloth until it is hardening.
