On-Site Painting

Brushes and Rollers are still the mainstay tools of the modern industrial painter, they may no longer apply the most paint on a project, but these important tools are used extensively to apply stripe coats to welds, edges and rivets, to “cut-in” two colours down a straight edge and to pick out the intricate colouring detail some of our structures require.

The advantages of Brush Application are:

  • Works paint into the surface
  • Minimal equipment costs
  • Relatively easy to use
  • Easy to clean and store
  • Displaces dust and moisture from the surface (before painting)
  • Good for stripe coating (edges, welds etc.)
  • Good for touch-up to painted surfaces
  • No requirement for compressed air, power etc.


There are of course disadvantages to this method of painting, such as:

  • Slow and labour intensive
  • Generally applies thin film thickness’s
  • Poorer quality of finish compared to Spray Painting.


Throughout our works we encounter many different structures; some are easily accessible whilst others contain thousands of narrow nooks and crannies. In order to apply enough paint to achieve the required Dry Film Thickness (thickness of a coat of paint once dry) in these hard to reach areas our painters utilise a variety of professional brushes such as:

  • Flat Brushes, for large flat surfaces where spraying is impractical
  • Dogs-Leg Brushes, for inaccessible locations and thin steel bars/girders
  • Fitch Brush, used in small areas for cutting in and stripe coating


When working upon structures where their are large areas of unobstructed flat steel our ICATS trained industrial painters may utilise traditional rollers to apply the protective coatings. Advantages of roller application are:

  • Faster than brush application.
  • The roller head is available in various fabrics allowing the roller to be used with a wide range of paint materials
  • Extension poles allow the painter to apply coatings to various heights without scaffolding and towers ETC.
  • Very easy to use.


The disadvantages of roller application are:

  • Although faster than brush application, still more labour extensive compared with spray application methods.
  • On other than on completely flat surfaces an element of brush painting will also be required.


As you can see from the points highlighted more traditional methods of hand painting are still widely used throughout the industrial painting industry; however to apply large volumes of paint to the structures we often refurbish requires a somewhat quicker and more reliable method of application, which is where the electric spray pumps are used.
