Spray Painting Cladding

Spray Painting Cladding

By Andew Sutton


Many industrial and retail premises have been constructed from profiled steel cladding over the past 30 years. Designed to last the life of the building, it can deteriorate over time, with the paint and varnish on installed cladding degrading. Cladding painting and cladding spraying is a cost effective alternative to the replacement of cladding that needs replacing. The fabric of the building is returned to its original, as new, appearance and will last another long period of time as well as making the industrial unit look new again.

As with all materials exposed to the elements, during the life of the cladding, there will be a cycle that takes place as the finish of the cladding breaks down. Starting life as new, the colour and the gloss level will remain as if it has been delivered from the factory. The first sign of the cladding paint system failing is Chalking. At this stage you may be able to wipe your hand over the cladding panel and a white film will appear. The coating is fine but the appearance of the colour and gloss level may have begun to fade and look dull.

Next is the breakdown of the existing coating. This is recognised as the next stage of degradation. Cracking may appear and the substrate may be visible on close inspection. It is advised that treatment, such as cladding painting or cladding spraying is carried out before any further weathering and corrosion sets in.

Allowed to degrade further, the metal substrate of the cladding will corrode, leading to total failure of the metal cladding. This is the final stage in the degradation process. This stage can be costly and time consuming to repair and replace as well as very disruptive to the work schedule.

Obviously, preparation is key for ensuring the maximum performance from the coatings. Your chosen company for Spray Painting Cladding, Cladding Painting and Cladding Spray will clean, degrease and protect the surface prior to application to ensure the quality of the coatings performance is not compromised.

After the process of having the cladding panels spray painting cladding sprayed the cladding panels are durable, weather resistant, hard wearing and colour fast. They can be treated just like new panels. There should be a standard 5 year paint warranty included in the package.

Cladding spraying and cladding painting is applied on-site and in-stu. A proprietary cladding coating PVC94 is typically used, meaning the fabric of the building is returned to its original as new appearance. PVC94 is compatible with Plastisol, PVF2, Silicone Polyester and plasticised finishes on metal and other common cladding types. PVC94 is an advanced technical coating and is essentially fire retardant in its dry form and has excellent ultraviolet resistant properties. Business premises can continue to trade throughout the procedure, which is ideal for retail stores, offices and warehouse premises who rely on public access to their units.

There should, prior to cladding painting, be a site survey. The area should be surveyed by the estimating team. The main areas to be looked at are: condition of existing substrates and access needs. The recommendations should be sent to the client, which should include: materials that are to be used for cladding spraying and the paint product data sheets. Access arrangements will be confirmed, along with a quotation to carry out the necessary spraying works. Once instructed to start by the client, site specific risk assessments, method statements and COSHH sheets will be supplied. The time table of work will also be agreed, bearing in mind that the office or factory can remain open during the works.
