Water-soluble wall and ceiling paints for interior use, so-called dispersion paints, can be easily sprayed on with Wagner paint spray systems. With the help of this step-by-step guide you will learn what to keep in mind when spraying wall paints, what the advantages of spraying are and how easy our spraying technology is to use.
Wall paint is a compound of various materials, mostly based on acrylic or synthetic resins. Most important for you are the pigments that determine the colour of the wall paint. Binders and solvents ensure that the individual components do not separate from each other and that the paint remains a uniform, homogeneous mass. Fillers such as calcium carbonate and silicates are responsible for the consistency and volume of the paint. This is the main difference between high-quality and inexpensive wall paint: With high-quality wall paints, the proportion of pigments is higher and the proportion of fillers lower than with the cheaper variants. This is the reason for the difference in opacity. Additives ensure better functionality of the paint, for example additives against mould formation in outdoor areas, or special effects in the finish, such as glitter or shimmer particles. Wall paints also need preservatives to prevent them from spoiling in the pot and to guarantee a certain durability.
Meanwhile there are also natural colours available. Instead of synthetic resins or those made of Mineral oils are used here mainly vegetable oils. Primarily linseed oil or castor oil, which makes the natural colours more expensive than the regular wall colours on synthetic or mineral oil-based. The natural ingredients should be healthy and Protecting the environment. However, if you also use regular wall paints with the seal of TÜV, the blue angels or consumer protection organisations such as Ökotest and Stiftung Warentest, then these too are completely safe for use.
One of the key features of dispersion paints is that they are water-soluble. Water-soluble wall and ceiling paints have several advantages:
The original method of applying paint to a wall is of course with a brush and paint roller. Lately, however, far greater emphasis has been placed on paint spray systems, which are used to spray the paint onto the wall or ceiling. In contrast to painting, you can save a lot of time and effort when spraying, as difficult-to-reach areas such as the corners of rooms can be covered more easily. Another advantage over using a roller with wall paint is a visually superior finish. Spraying makes the surface texture much more uniform and consistent. Further advantages of spraying can be found here in our FAQs.
Once you have mastered the spraying technique, you can quickly coat large areas with wall paint. In addition, working with a paint spray device is a pleasure for most users. However, whether spraying or painting with wall paint, ensure that the room is well covered and masked before you start. For more information on how to tape a room correctly, please refer to our FAQs.
With a paint spray device from Wagner you can spray a wide range of objects, walls, ceilings and even wood. It's important to take the appropriate precautions and prepare both yourself and the room before using the spray unit. You should also master the required technique. Our step-by-step guide shows you the best way to get started:
Before you can start painting, you may have to remove the old wallpaper or wallpaper residue from the wall. Carefully check the wall for holes and unevenness. In case of severe unevenness, you may need to apply some filling compound.
With a large universal brush you can easily remove dirt and dust to ensure a clean surface.
To protect the surrounding furniture, cover it with a generous amount of protective film. Skirting boards, windows, light switches and door handles should also be protected from paint splashes using masking film.
Whenever you use a spray unit to apply paint, you should also wear a breathing mask and protective goggles.
For use in a spray unit, the dispersion paint must have the right consistency and should not be too thick. Viscous wall paint may cause the device to become clogged – it's a good idea to use a suitable thinner (or simply water) to make the paint sufficiently liquid. Pay attention to the information on the packaging – some paints are specially designed for use with spray units.
Depending on the specific paint spray system, you must adjust the unit accordingly and then fill it with the wall paint. When using HVLP paint spray devices, the air flow must also be correctly adjusted, as this determines how much paint will come out of the gun. Before spraying on the wall, be sure to perform a test spray on some paper or wallpaper. Depending on whether the pressure is too high or too low for your application, you may need to adjust the settings accordingly.
In most cases you can also make adjustments to the jet width to find the best setting for your project.
In order for the paint to cover the wall thoroughly, the spray unit must be held at an angle of 90 degrees to the wall. It is important to avoid any swivelling movements with the gun – instead try to coat the wall vertically from a distance of about 20-25 centimetres with our airless units and 20-30 centimetres if using our HVLP paint spray systems.
Cleaning should take place immediately after you complete the work, as this is when the paint is easiest to remove. To remove water-soluble wall paint from your paint sprayer, it's best to use simple tap water and disassemble the device into its individual parts. Rinse the paint container or spray gun with water to remove all traces of the dispersion paint. Depending on the type of equipment used with the device, filters, sieves or other components may also need to be cleaned. You can simply rinse the other parts with lukewarm water.

WAGNER is a specialist in airless atomisation and "High Volume Low Pressure" technology. Both technologies can be used to apply wall paints.
Our HVLP paint spray systems are designed for low-pressure spraying, in which high air volumes are combined with low air pressure (up to 0.07 MPa). With the FineSpray method, wall paints are completely atomised with air at the outlet of the nozzle. The low material pressure combined with the high volume of air ensures slightly larger material droplets and therefore less spray mist. The following HVLP paint-spraying systems, which are ideal for DIY enthusiasts, allow easy spraying of wall paints.
In contrast to air atomisation, airless atomisation means the wall paint is atomised solely via the material pressure without the use of air. At the same time, the material is dissipated into a spray jet.
The following airless units are ideal for tradespeople who need to spray wall paints:
