Airless sprayers for spackle and putty

The processing of spraying spackle and putty or stucco with an airless device is becoming increasingly important. Customers who used to ask for wallpaper in the past often want smooth and clean walls today. An airless spatula offers some advantages like fast and easy working. With an airless device for spraying spackle and putty or stucco, large surfaces can be processed quickly in high quality. Moreover, a spraying device for putty can be used not only quickly but also uniformly. While with the manual application of putty, much is left to experience, you will quickly find that with an airless spraying machine you can achieve high-quality work results in a short time. In addition, the airless paint sprayer can also be used for priming, spraying the dispersion paint after filling, as well as for the use of other spraying materials such as facade paints, silicate and latex paints, fire protection or roof coating. With a paint sprayer of this class, you are also equipped for many other work areas and can cover additional orders if necessary.

Advantages:

  • faster job thanks to high surface coverage
  • quality work
  • easy to use
  • application of other materials such as primer and dispersion paint

Attention: not every airless device is suitable to spraying spackle and putty. The airless paint sprayer should have enough power (4 liters delivery rate per minute or more). As a rule, an electrically operated piston pump is recommended since airless piston pumps can process and convey thicker and highly viscous spraying materials better. In addition, the sprayer accessories should be designed for putty. The spray gun, the nozzle, the hose and the filter should be adapted to the thick filler material. Airless spray filler is thick and is processed in large quantities, so the passage is usually larger than for a finish or dispersion paint. Therefore, the gun should be suitable for putty and be operated without a filter. The hose should have an internal diameter of 10 mm (DN10), 13 mm (DN13) or more. The main filter should be removed from the paint sprayer and the lower inlet strainer should be coarse mesh to provide protection, but also to pass the filler compound.

Which airless sprayers are suitable for spraying putty?

Here are some common sprayers from Graco, Wagner and FARBMAX, which can be used to process spray putty:

Graco Mark V – the starter model

The Graco Mark V is the entry-level model for spraying compounds. The delivery rate is 4.3 liters per minute and the maximum nozzle size is 0.037″. The machine is compact and the weight in the standard version is 59 kg. The supplied spray equipment, consisting of 15 m hose (3/8), hose whip, Graco HD Blue gun and RAC X nozzle, is designed for the processing of spray putty. For very thick putty or large surfaces it is recommended to use a more powerful spraying device.

 

Graco Mark VII – the big brother of Mark V

The Graco Mark VII can be described as the great brother of Graco Mark V. With a maximum delivery rate of 6.0 liters per minute and a maximum operating pressure of 230 bar, thicker compounds can be sprayed up to a nozzle size of 0.041″. The design is also quite compact and the weight is 63 kg in standard version and 73 kg in the ProContractor variant. The Graco Blue HD spray gun is also available in the Graco Mark VII range. However, the hose is thicker (1/2 “thread with 13 mm inner diameter of the hose) than with the V mark to ensure the passage for the higher flow rate of the Mark VII. For spraying primer, dispersion and other materials it is worth buying an extra equipment consisting of spray gun, nozzle, hose and filters.

Wagner ProSpray PS 3.39 – agile and powerful

The Wagner PS 3.39 is the lightest spraying device for spraying putty on the market, but still brings a lot of performance. The German manufacturer Wagner has achieved the balancing act here and offers a spraying unit with only 44 kg, despite a delivery rate of 5.0 liters per minute and a maximum nozzle size of 0.039″. Especially for small companies an interesting solution or if only one man is on the construction site and has to handle the transport and the loading and unloading of the device from the car alone. The Wagner Airless is equipped with a 1/2″ hose with 13 mm inner diameter for putty as well as the AG14 or AG19 gun for filler compound and a corresponding nozzle. A quite practical feature is the separate main filter seal for filler compound as well as the oil tank.

Wagner HeavyCoat HC 950 SSP – high performance with scoop piston

The Wagner HeavyCoat HC 950 SSP is suitable for very large projects such as multi-family houses, commercial buildings and industrial buildings, as well as for medium and large jobs up to 800 m² daily output. For the processing of materials, we recommend the equipment version SSP, an additional scoop pistone, which supports and simplifies the processing of thick spray media. The maximum delivery rate is 6.6 liters per minute (nozzle: 0.052″), the maximum working pressure is slightly higher than the Graco models. The weight is 84 kg with the SSP scoop piston, without SSP one kilo less. The delivery from the manufacturer takes place in the spatula equipment with a 1/2 “hose with 13 mm inner diameter and the Wagner AG19 spraying gun with a special nozzle for putty.

Wagner HeavyCoat HC 970 SSP – it does not get more powerful

The Wagner HeavyCoat HC 970 SSP is the most powerful Airless paint sprayer in its class. 10 liters per minute of delivery rate with a maximum working pressure of 250 bar and a nozzle size of up to 0.056″. In other words, a sprayer for the very large painting jobs and highly viscous materials. With the HC 970, surface capacities of more than 800 m² per working day are possible. Again, the SSP dosing unit is available for highly viscous spray media such as spackle and putty. With a 1/2″ hose with an internal diameter of 13 mm, the Wagner AG19 spray gun and the appropriate nozzle putty, this airless machine is perfectly equipped for spraying job with putty. To obtain high performance, a 400 V connection is required, which should be available on most major construction sites. The weight corresponds to the power and is 100 kg, one kilo more in the SSP scoop piston version.

FARBMAX Airless 6400 – the alternative

The FARBMAX Airless 6400 now also offers an alternative to Graco and Wagner in the putty spraying tooThe FARBMAX Airless 6400 has a delivery rate of 6.4 liters per minute with a maximum operating pressure of 227 bar. The maximum nozzle size is 0.039″. The airless unit is quite compact and weighs 61 kg without hose and pistol. The sprayer is equipped with a 3/8″ high-pressure hose with an inner diameter of 10 mm for putty, as well as a suitable spray gun and airless nozzle.
