The quality of a wall print, vinyl wrap, or wallpaper solution hinges on the condition of the substrate.
As a professional service provider in the fields of signage technology and wall design, we know that only a properly prepared surface guarantees a lastingly perfect result.
Below, we explain which substrates are suitable, how to prepare them, and what to consider regarding durability, removal, and adhesion.
Why checking the substrate is so important for wall printing
Every substrate behaves differently.
Whether it is plasterboard, plaster, concrete, or wood-based panels—material composition, absorbency, moisture levels, and surface texture decisively influence the adhesion of paints, films, or wallpaper.
Therefore, before any lettering, wrapping, or direct printing, we check:
- Load-bearing capacity and strength
- Moisture content and drying
- Coating type and surface structure
- as well as the liability conditions under real-world climatic conditions
This analysis of the substrate forms the basis for deciding whether to use direct printing, film application, or a special wallpaper solution.
Suitable substrates for wall printing and vinyl wrapping
Rigips / Plasterboard
Plasterboard is widely used, but it is only suitable if it has been skim-coated over the entire surface, primed, and allowed to dry.
Untreated panels, or those with spot-filled areas only, can absorb moisture, potentially leading to discoloration or detachment.
Uniform, smooth surfaces are crucial for wall printing and film application.
Plaster and masonry (Poroton, Ytong, sand-lime brick)
Each type of stone has its own properties: Ytong is highly absorbent, sand-lime brick is relatively dense, and Poroton is porous.
Therefore, even plastering and priming are important.
Loose, sandy, or unevenly textured surfaces must be consolidated to achieve clean printing or adhesion results.
Concrete and exposed concrete
Concrete generally offers excellent bonding conditions—provided it is dry, clean, and free of formwork oil or release agents.
However, adhesion may be limited on sealed exposed concrete surfaces. In such cases, applying a test sample or performing a tack test is recommended to verify the bond strength.
Composite panels, wood, and MDF
Lacquered, foil-wrapped, or coated panels require special preparation:
The surfaces must be degreased and, if necessary, lightly sanded.
Untreated MDF boards are highly absorbent and must therefore be primed or sealed before printing or applying adhesive materials.
Our application systems: wrapping, wallpaper, and wall printing.
We work exclusively on sound, uncoated substrates where the composition and coating are known. We do not work over existing wallpaper or unknown coatings, as we cannot guarantee adhesion in such cases.
Instead, we offer three equivalent system solutions, selected according to the project objective:
a) Wraps
High-quality films are ideal for smooth, solid surfaces. They enable razor-sharp graphics, brilliant colors, and a clean, uniform finish.
Whether temporary or permanent – we select the right material for your project.
b) Wallpaper solutions
We use our own wallpapers featuring various textures and finishes—ranging from satin-matte to finely textured. These are professionally applied and serve either as a design surface or as a base for subsequent wall printing.
This creates unique, high-quality wall designs with texture and depth.
c) Wall printing / Direct printing
With wall printing, the image is printed directly onto the prepared wall or onto wallpaper installed by us. This direct printing method produces vibrant, durable results and creates a particularly authentic look and feel.
Depending on the substrate, the texture can be deliberately used as a design element.
Adhesion, durability, and removability
Long-lasting application – maximum adhesion
For long-term projects—such as interior fit-outs, public spaces, or showrooms—we use materials with strong adhesion or UV-resistant inks. These applications are exceptionally durable but should only be installed on suitable, stable substrates.
Temporary application – residue-free removal
Short-term applications are frequently required in event, trade fair, or gallery settings. In these cases, we use removable materials that—provided the substrate is suitable—can be taken off without leaving a residue. Nevertheless, a residual technical risk remains, such as the possibility of adhesive residue or slight paint detachment.
Adhesion optimization with primer
For surfaces that are difficult to bond to or highly absorbent, a primer (adhesion promoter) can be used. It improves adhesion and ensures a uniform bond between the material and the wall. This measure is optional and is charged as an additional service.
Sample application and tack test
To objectively assess the suitability of a substrate, we can carry out a test application upon request. This involves applying the intended material to a small area to verify its actual adhesion performance.
In addition, we offer the tack test:
Adhesive strength is measured in Newtons (N) using a digital measuring device—both immediately after application and after a defined dwell time. This measurement provides a precise assessment of how adhesion develops and serves as an important quality assurance tool.
Both methods are highly recommended for high-quality surfaces, new paint systems, or unknown wall coatings.
Dependence on intermediate inputs
Walls are often prepared in advance by other trades—such as painters, drywall installers, or plasterers. We cannot accept liability for defects resulting from surfaces that are insufficiently dry, not fully cured, or improperly primed.
Likewise, we assume no liability for residual moisture, cracks, or loose layers of paint that subsequently lead to detachment. Responsibility for adhering to drying times and standards regarding the substrate lies with the client or the trades responsible for preparatory work.
Residual risk due to technical factors
Despite the utmost care, substrate inspection, and material selection, a residual technical risk remains. Adhesive residues, paint detachment, or minor surface damage can never be completely ruled out given the thousands of different wall constructions.
These effects do not constitute grounds for a complaint but are inherent to the physical properties of the material. We therefore strongly recommend applying a test sample—optionally including a tack test—to objectively evaluate adhesion and removability beforehand.
Conclusion
Whether it involves wall printing, vinyl wrapping, or wallpapering, the choice of the right system always depends on the substrate. Only proper preparation and assessment guarantee that design and technology work together perfectly.
Drawing on our experience, modern testing methods, and professional substrate assessment, we create durable and visually impressive results—ranging from museum-style installations to permanent interior design.
