Spray grouting with an Airless pump is a common method used to apply grout to walls or surfaces. The professional airless pump is a device that uses pressure to spray material, without the use of compressed air. Grouting is essential in order to make the walls uniform and with an even surface, as well as to allow optimal attachment of tiles and wallpaper.
Spray grouting: the process with the airless pump
Here you will find all the necessary steps to be able to carry out grouting with a professional airless pump optimally and efficiently.
Surface Preparation: Before starting the grouting, it is important to prepare the surface properly. This could include cleaning the wall, removing old layers of paint or plaster and repairing any cracks or holes.
Preparing the putty: Prepare the putty according to the manufacturer’s instructions. Make sure you achieve the desired consistency for proper application with the Airless pump. Recommended professional airless pump: Putty usually has a high viscosity, so it is advisable to use an electro-hydraulic piston pump, the only ones capable of generating an adequate suction force, far superior to traditional electric diaphragm airless pumps. Recommended models:

Preparing the pump: due to the high suction force exerted by the electro-hydraulic piston pump, immerse the pump directly into the can or drum. This leads to a further advantage, namely the reduction of cavitation of the filler during the suction phase.
Pressure adjustment: The professional airless pump allows the pressure of the outlet to be adjusted. It is important to adjust it according to the consistency of the putty and the surface to be treated. Too high a pressure may cause excessive or uneven spraying, while too low a pressure may not provide even coverage. Too much pressure could affect the longevity of the airless pump.
Filler application: Once the Airless pump is ready and the pressure has been correctly adjusted, you can start spraying the filler onto the desired surface. Make sure to keep the pump gun at a constant distance from the wall to achieve even coverage. Move the gun slowly and evenly to avoid build-up or thin areas.
Finishing: After the filler has been applied to the entire surface, the desired finish can be applied. This could include sanding or texturising the filler to achieve the desired final appearance.
