Airless Spray

Airless spray is achieved by subjecting paint material to a high pressure (through electrical, pneumatic, or hydraulic means) and forcing it through a hose.  When the paint reaches the nozzle, it atomises into a spray.


Airless Spray is best used to cover very large, flatter areas (such as ships) relatively quickly and evenly compared to other conventional paint application methods.

Voids, crevices and any deep pitting in steelwork however can still be missed by this method of application.

Air (Conventional) Spray

Similar to Airless Spray, air spray or more commonly known as conventional spray introduces an external compressed air source that subjects paint material to pressure.  When the paint reaches the nozzle, it atomises into a spray.  It can cover larger areas relatively quickly and evenly.

Unlike airless spray, it tends to operate at changeable, lower pressures, allowing for a higher degree of painting control and safety to the operator.

Aerosol Spray Can

The paint material is typically compressed into a single can.  When the button is pressed, a stream of paint spray is released under pressure.  This type of spray tends to be suitable for small areas only and is not particularly economical.

Pouring / Flooding

Quite simply the paint material is poured into/onto the surface that requires treating. This is a great method for harder to reach voids or small diameter internal surfaces.  However, there is limited control over the amount of material coverage and so other considerations such as rotation of the item being covered and forced air movement have to be considered to ensure a full, consistent, even coverage.


Dipping is where the item to be treated is placed into a tank filled with the coating or paint material itself.  Like pouring, this is an excellent method for painting those hard to reach places but again, other considerations such as forced air movement have to be considered to ensure a full, consistent, even coverage.


One of the traditional methods for painting and is well known to all DIY enthusiasts and industrial applicators alike.  Painting by brush is not the most economical or efficient method of coating (due to having to frequently having to replenish the material onto the brush), but it has its uses.  Crevices and pits can be more easily touched in. Site based maintenance painting can be better utilised by brush, where a spray and lack of ventilation is a problem.


Much like the paint brush, the roller is another common application method.  Like the brush, it may not be the most economical method of painting, but again is suited to site maintenance painting where ventilation is limited and is far more efficient at covering a large area than a brush.
