Painting |
|
INTRODUCTION |
The vast majority of products
and projects today require a finished application usually in the form of
oils, lacquers, solvent based paints and water based paints. The choice
primarily is to apply the material with a brush, sponge, rag or spray gun.
Speed, quality of finish and versatility are the main criteria when
selecting.

|
|
This method of finishing can be slow and labour intensive although the
results are of a high standard. When undertaking a project these aspects
should be reduced to a minimum as the time spend on finishing a project can
equal the time spent on producing the project.

This method of painting offers many advantages including: |
|
 |
Ease
of repair
As spray
finish is built up in thin layers, small scratches and blemishes are not so
obvious and significantly easier to remedy.
Speed
A finish
can be sprayed on a multitude of shapes and sizes much faster then ever
could be done with a brush or rag. In addition, as the finish material has
been broken into small particles by a stream of air (atomisation), it dries
very quickly. Varnishes, lacquers and water based products dry to the touch
in minutes and can be sanded and recoated in as little as an hour. Applying
several coats of finish in one day makes this process very efficient. Also
due to the rapid drying time dust particle have very little time to settle
which reduces and at best eliminates the need for sanding between coats. |

Versatility
Any finish
that can be applied by brush or rag can be sprayed, however not all finishes
that can be sprayed can be brushed or wiped. Spray painting also allows for
techniques such as toning or shading, which cannot be applied effectively by
hand.
Control
Using the
right techniques with a correctly prepared spray gun will allow for
excellent control over how and where the finish is applied. Adjusting the
pressure, air fluid flow and fan size will allow light and even coats thus
eliminating thick spots and brush marks |

Easy
to learn
Spray
painting is relatively easy to master and a professional finish can be
achieved much quicker than with conventional methods.
Quality finishes
Investing in a spray system will provide a quality finish on a consistent
basis. Many problems associated with a hand finish such as drips, sags and
trapped air bubbles are vastly reduced or eliminated |

USE YOUR SPRAY GUN FOR: TIME SAVING – VERSATILITY – QUALITY FINISH – EASE OF
LEARNING - |
|
OTHER CONSIDERATIONS |
Due to
atomisation a fine cloud or mist of paint is released into the air.
It is vital that due consideration is directed to personal safety,
protective clothing, etc.
Standard
facemask or air fed mask.
Suitable overalls or clothing
Good ventilation, using a fan or extraction system
Dust free work area (workshop, or garage).
Naturally,
a serious hobbyist would have enough protection with the use of a standard
facemask in a well-ventilated area. Poorly ventilated areas such as
basements or workshops would require one of the fan systems.
