The viscosity of emulsion paint, ready to eat, is given in Table. 34. table 34. Spraying viscosity A waterborne emulsion paints (by viscometer VZ-4, C) Paint Application Method Brush or roller, a paint sprayer polyvinyl 70-100 25-35 Styrene-butadiene 45-50 30-35 Prior to the spray gun test reliability accession suction and discharge hoses and gauge, flushed and fastens the nozzle. To during the gun is not further inflate a balloon air, do it before charging it with paint.

Lowering the suction hose with a filter in a bucket or pail with a paint composition, initially pumped into the tank unwise to paint. After removing the hose from the bucket, air is pumped to a pressure of 1,5-2 kg / cm 2 and fill the tank painting structures. For painting interior surfaces do not need scaffolding or ladders, because the length of the rod allows you to paint the ceiling and upper walls, standing on the floor. When painting the facades of buildings used cradles or mobile towers. When spraying nozzle centrifugal type paint layer applied to the surface is uneven: Coverage Rate in the center of the circle is smaller and the edges more.

This is because the ink particles, flying out of the nozzle under centrifugal force, are dropped to the edges of the circle. Fig. 69. The movement’s daughter from a nozzle at painting very important when painting is the distance from the nozzle to the surface to be painted. The length of the ink jet depends on the viscosity of the composition, the diameter of the outlet nozzles and pressure on the paint composition.
