Application tips

Before spraying, the surface must be clean, dry and dust-free. On new plaster or ceilings, light sanding followed by dusting with a brush or vacuum cleaner ensures even adhesion of the product and prevents visible surface defects once dry.

The ProSpray 3.39 comes with an Airless Vector Pro spray gun and a quick-change nozzle holder, allowing the nozzle to be adapted to the product being sprayed (wall paint, thin plaster, fibreglass adhesive) without interrupting the job. The 2Speedtip system offers two flow settings, making it easy to switch from a fine finish to a more generous application on large surfaces.

For longer jobs, it is advisable to regularly check the electronic display to adjust the pressure according to the product's viscosity and avoid the "pigtail" effect (a poorly formed spray pattern), a sign of unsuitable pressure or a worn nozzle.
