Most objects are continuously or periodically exposed to 
weather. Sun and wind, rain and snow, heat, cold and moisture
attack the surfaces. This is why the protective coating needs
to be as resistant as possible.
Paint brushes versus paint
spraying units
THE COMPARISON: 
PAINT BRUSHES VERSUS PAINT
SPRAYING UNITS
In a trial conducted by
Wagner, paint brush and paint
spray unit were compared
with each other. In order to
check the difference in the
application of paint and its
durability, different common
types of wood were chosen.
Each individual piece of wood
was coated, partly with a 
normal commercial paint
brush of average quality and
partly with a paint spray 
gun, and then exposed to 
the weather.
A clear result
In some places the wood sections painted with the
paint brush exhibited a complete breakdown of the
coating material. The coating applied with the spray 
gun on the other hand showed itself highly resistant
to the effects of weather.
Paint application with a normal commercial paint 
brush holds a risk of ridges being formed, if the paint 
is applied to thickly and unevenly. This offers a greater
surface for the weather to attack. Moisture remains 
trapped in the ridges left behind by the paint brush 
and thus attacks the coating.
