Application
Priming and final coating of large areas, sealing, impregnation,
construction sanitation, façade protection and renovation, rust
protection and building protection, roof coating, roof sealing,
concrete sanitation, as well as heavy corrosion protection.
Examples of objects to be sprayed
towers, bridges, sewage treatment plants and terraces.

Coating materials
Processible coating materials
Pay attention to the Airless quality of the coating
i
materials to be processed.
zinc dust and micaceous iron ore paints, airless spray primer,
sprayable glue, anti-corrosive agents, thick coating materials and
bitumen-like coating materials.
No other materials should be used for spraying without Wagner's
approval.
Filtering
In spite of the high-pressure filter, filtering of the coating material is
to be recommended in general (except when processing airless joint
filler).
Stir coating material before commencement of work.
Make sure when stirring with motor-driven agitators
i
that no air bubbles are stirred in. Air bubbles disturb
when spraying and can, in fact, lead to interruption
of operation.
Viscosity
It is possible to work with high-viscosity coating materials with these
devices.
If highly viscous coating materials cannot be sucked up, they must be
diluted in accordance with the manufacturer's instruction.
Two-component coating material
The appropriate processing time must be adhered to exactly. Within
this time rinse through and clean the unit meticulously with the
appropriate cleaning agents.
Coating materials with sharp-edged additional materials
These have a strong wear and tear effect on valves, high-pressure
hose, spray gun and tip. The durability of these parts can be reduced
appreciably through this.

Description of unit
3.1
Airless process
The main area of application are thick layers of highly viscous coating
material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it
to the tip. Pressed through the tip at very high pressures, the coating
material is atomized. This high pressure has the effect of micro fine
atomization of the coating material.
As no air is used in this process other than to power the pump (Air-
force material from the spray gun (Air-Assisted).
This method of spraying has the advantages of finest atomization,
cloudless operation and a smooth, bubble-free surface. As well as
these, the advantages of the speed of work and convenience must be
mentioned.
3.2
Functioning of the unit
The following section contains a brief description of the technical
construction for better understanding of the function.
Wagner SuperCoat are high-pressure spraying units driven by air
power provided by an air compressor.
An air compressor connected by an air hose drives the air motor (1)
which then moves the piston up and down in the material feed pump
(2), drawing up spray material via the siphon hose (3).
The air regulator (4) controls the air pressure being allowed into
the system, and is directly proportionate to the fluid pressure being
produced.
Example: SuperCoat 30:1
6,9 bar (0,69 MPa) reading at air gauge (5) = 207 bar (20,7 MPa) at
pump outlet
The inlet valve is opened automatically by the upwards movement
of the piston. The outlet valve is opened when the piston moves
downward.
The coating material flows under high pressure through the high-
pressure hose to the spray gun. When the coating material exits from
the tip it atomises.
