Is it possible to use paper wallpaper together with concrete at all?

The most common and easiest material for wall treatments is still wallpaper. What was used to construct these walls is irrelevant.

Wallpaper offers a lot of benefits.

  • Various assortment.
  • Easy operation. Even novice craftsmen can easily handle wallpaper.
  • Low cost.

Note: There will be a positive response to this query. However, only those who consider every nuance of the subject matter will come out on top. The base needs to be carefully prepped.

In material work, priming concrete walls for wallpaper application is a crucial step.

This stage has benefits of its own when it comes to concrete:

  • Concrete surfaces in finished form are usually uneven, curvature.
  • It is prohibited to apply wallpaper made of paper to such walls. There will be no result from this action.
  • Without preparation, it will not even be possible to join both materials closely to each other. There is a high probability of gaps appearing.
  • The concrete itself has a rough and grainy texture if you take the material without preliminary processing.
  • If you immediately glue the wallpaper, all the flaws will immediately come to the surface. Especially if the wallpaper is thin enough.
  • The instructions usually contain an indication of possible problems.
  • Initially, the concrete is dark gray. Only in some models the shade becomes somewhat lighter. Because of which the wallpaper can change its design. The result rarely pleases consumers.

Kindly take note. White dots will undoubtedly appear on the surface if you do not know how to prepare the walls for applying wallpaper adhesive. This occurs as a result of the glue’s uneven application on the wall.

  • Bubbles may form when the glue hardens. Because of which the products are likely to come off the surface, although partially.
  • Finally, if you do not pre-prepare the concrete, there will be a greater chance that mold will develop in the structure.

What work can be done to prepare the walls?

Each option’s price is established independently:

  • Direct pasting with wallpaper or fabric (see. Fabric wall covering: an interesting decor option).
  • Finishing using wood or plastic.
  • Sheathing with plasterboard.
  • Painting together with plaster and putty.

Every solution has subtleties of its own that are necessary to produce work of a high caliber. Furthermore, it is impossible to comprehend how to get the walls ready for wallpapering without it.

Getting rid of old materials

Name of material How to remove it?
Paint Grinding machine with a metal brush, solvent (see. How to remove paint from concrete quickly).
Whitewashing The simplest option – just a sponge and hot water.
Enamel or oil paint Sandpaper.

About the simplest and most budgetary solution

Using newspapers is the most affordable choice. Trying to find the best solution on a tight budget is challenging.

The newspapers themselves and glue are the only supplies you’ll need. The available material should be used to cover the walls completely.

What are the benefits of priming walls in this way before applying wallpaper adhesive?

  • Guarantee that the two bases will be securely fastened to each other. Newspapers stick well to literally any surface, creating an almost ideal base for wallpaper in the future.
  • Alignment of the structure and relief at a high level of quality.
  • Simple execution. No additional professional skills are required.
  • Very low cost.

Pay heed. There is a significant chance that the paper will develop mold. In apartments with improperly installed ventilation systems, this is an unavoidable issue.

We’ll talk about more contemporary techniques next.

Using concrete contact

Its strong resistance to alkalis is its primary attribute.

The components of quartz sand are as follows:

  • Due to the use of this material, the adhesion between two adjacent surfaces increases.
  • Efficiency together with easy operation are the main advantages.
  • Betonokontakt helps to level the density of the base and fills all the pores (see. Betonokontakt – primer for surface preparation). Thanks to which, after drying, a monolithic structure is formed. You can start working immediately after purchase. It is enough to thoroughly mix the material, and you can apply it to the surface.
  • A roller with a tray will become indispensable assistants in this case. If you do not have them, ordinary brushes will do. The main thing is to apply betonokontakt evenly, in straight lines in the vertical plane, everything is done with an overlap.

Note: Preparing the walls does not necessarily mean leaving untreated areas visible before applying wallpaper.

How to use underlays?

Wall substrates may also develop into a unique choice:

  • This method is more suitable for those who paint non-woven wallpaper. The substrates themselves are made of polyurethane or natural cork.
  • A truly universal product that not only allows you to connect wallpaper to the wall, but also provides sound and heat insulation at a high level.
  • The substrates themselves are glued directly to the concrete, on top. Cork or polyurethane substrates use a separate type of adhesive.
  • It is applied to the material in stripes. Thus, an additional layer is created.

Note: Note that the primary benefit of substrates is their resistance to the growth of mold and fungus.

Using putty as a leveling layer

DIY Putty is an effective way to prepare walls for wallpaper application if the surface is initially uneven, has numerous cracks, or has other similar defects.

Plaster is applied to the surface after it has been primed:

  • It is the latter that fills the cracks and helps to finally level the surface.
  • The ideal option for solving the problem is to use a gypsum composition. Gypsum plaster helps to create a uniform coating, over which any liquid is then evenly distributed.
  • Thanks to which the material becomes suitable for any type of processing in the future.
  • Priming is generally recommended to be performed after the completion of each stage of the work. But only after the previous layer has dried.

Kindly take note. The preparatory work is less complicated when liquid wallpaper is utilized. It only takes a single putty and primer; no additional materials are needed.

To ensure a smooth and durable wallpaper application, concrete walls must be properly prepared. Take the time to thoroughly clean the surface, fix any flaws, and apply a suitable primer to create the perfect foundation for the wallpaper to adhere to.

Keep in mind that every step of the preparation process—from surface sanding to filling in cracks—is essential to the result. Wallpaper that eventually peels, bubbles, or has uneven surfaces can result from rushing through or ignoring these chores.

A well-prepared wall not only makes your space look better, but it also prolongs the life of your wallpaper, so your time and money are well spent. You can achieve a professional finish that changes your living area by adhering to these guidelines.

In order to achieve a seamless and durable wallpaper application, it is imperative to prepare concrete walls beforehand. This procedure includes priming the concrete to seal it and enhance wallpaper adhesion, cleaning the surface to get rid of dirt and dust, and patching any holes or cracks. In addition to making wallpapering easier, proper preparation improves the wallpaper’s longevity and overall look on your walls.
