Paint Spraying Step by Step
Back to Spraying & Painting
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
spent 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.
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.
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.
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.
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
