Getting started
A careful study of the equipment and its instructions is essential to understand the operation of this device. Indeed, before starting to paint, you must already choose the right nozzle, install under the pump your paint can and dip the suction pipe. It is also necessary to provide a second bucket of "emptying" and to place another pipe, essential for priming. These small manipulations seem compelling the first time. But the time lost is quickly caught when you start painting, given the performance of the device.
Once the hoses are connected to the machine and the chosen accessory (gun or roller), the air inside the pump and the supply hose must be expelled. The priming takes only a few seconds and then we go to the application of the paint.
If you opt for the gun, first choose the most suitable nozzle. The manual includes a table of the different types of products and the references of the appropriate nozzles. For our first test with a plasterboard underlay, we mounted a "413" nozzle.
Unlike the conventional spray gun that projects a mixture of air and product (with the usual "fog"), this system is content to spray the paint. This avoids the famous fog that is deposited everywhere in the room. On the other hand, we find the same way of painting: keep the pistol well perpendicular to the support and keep a constant distance of application (30 to 35 cm of the support). The finish is blameless but you must take the hand if you are not used to the gun.
On the roll side, once the system is primed, a simple pressure on the trigger feeds the fibers of the sleeve. No need to get off the stepladder to recharge at any time.


  • A quick way to repaint the whole house, facade included.
  • The spray performance is important and the absence of fog allows to protect only the edge of the area to be painted, not the whole room!
  • The system accepts virtually all liquids: paints, stains, varnishes, treatment products (eg lumber).

The lessers

  • Apart from the price that remains a brake for occasional work, the device imposes some constraints, before and after work. Before, you must prime the pump, hoses and the device you are connecting (roller or spray gun). After, count well twenty minutes for the complete rinsing of the system and for its storage.

Our opinion

At this price level, you have to have a lot of work in perspective to amortize such a purchase... or partner with friends to share the investment. The system saves time and repainting the facade quickly becomes a mere formality.

Uniform coverage

Uniform coverage

The "Airless" spray does not cause fog, but the passes must be overlapped to unify the cover. In first layer, a kind of line marks the jet on the sides.

Continuous application

Continuous application

A valve facilitates the priming of the pump. The roller application is continuous. As long as you squeeze the trigger, the paint feeds the sleeve more or less evenly.
