PAINTING PROFILED SHEETS

The colour on all Coated Profiled Metal Roofing sheets and materials will fade in time, with the lighter colours fading quicker than the darker colours. Sheets can be repainted by brush or sprayer. A good quality gloss paint is recommended.

By referring to our Corus (British Steel) Colour Charts, you should be able to identify the colour required and its BS or RAL number CLICK HERE . It may be necessary to remove a few fixings on the building to expose the original colour under a sheets side or end lap. Looking under a barge board is another good place.

Please do read the introductory notes  to the Colour Charts so that you appreciate the problems that the industry has relating to matching colours and shades.  SLE Cladding Ltd has arrangements with a paint company to produce paint to any BS or RAL number.

 From the Colour Charts introduction it will be seen that a colour guarantee cannot be given to exactly match that of the existing building.

If an exact colour match is important or essential we suggest taking a sample from the paint container and adding a little white paint to lighten or black to darken to the sample. Trial brush the adapted colour over or near to the colour it has to match, and repeat until an acceptable colour is achieved. Don't risk blending a full tin in the first instance as you may find that any blend is worse that the original colour.

Painting New Materials.

New coated materials such as Plastisol, Polyester & Galvanised Steel will readily take paint and it will dry and appear very satisfactory. The problem is that in very hot weather the paint may peel off the sheet. It is best if painting can be left for 12 months for the surface to age a little. This is also particularly true of galvanised steel.

Painting New Galvanised Steel.

If painting has to be done immediately (Planners on your back) in the case of galvanised steel a Mordant etching solution can be applied to take the shine off the surface. Carefully follow the manufacturer's instructions. The sheets surface will need to be well washed immediately after application and allowed to dry before the paint is applied.
