Guide to painting cladding
The process: We prepare the cladding using a high-pressure washer at 3000psi with a turbo nozzle. This will remove any defective coatings and ensure the substrate is sound, removing any dirt, chalking and containments. For areas of cladding showing signs of oil contamination we use solvent degreasers to clean the substrate and make ready for a new coating.
If there are areas of rust, these will be scraped back to sound metal and treated with a rust converter & primed with a zinc phosphate or red oxide metal primer. Once the preparation stage is complete our cladding painters will start application of the specialist cladding paint by brush and roller or airless spraying if the site conditions allow.
Frequently asked questions:
Q. Can cladding be painted?
A. Yes, cladding can be painted. The important factor is correct preparation before application of coatings. Plastic cladding can be pressure washed to make it look like new.
There are many types of cladding: industrial metal cladding, wooden cladding, cement board cladding, plastic cladding. Read more on the best paint for different types of cladding in this page.
Q. Can you paint external cladding?
A. Yes, external cladding can be painted using water or oil based coatings
Q. Whats the best paint for metal cladding?
A. We believe Giromax Girocote is the best coating for metal cladding projects as it offers a 10 year guarantee. We alos use Zinsser Allcoat satin, a water based coating giving an expected lifespan of 15 years.
Q. How do you paint metal cladding?
A. Metal and plastisol covered metal cladding are best painted using this specification; Pressure wash 3000psi with turbo nozzle. Allow to dry and rub down. Apply 2 coats of Zinsser Allcoat (goes direct to galvanised).
Q. My wooden cladding has knots that have gone a different colour & bare of paint.
A. The solution to this issue is to scrape the knots back and remove any excess resin, then rub down & apply 2 coats of knotting solution. This will seal the knot and can be over painted with the resyt of the cladding.
Q. My plastisol / metal cladding has discoloured from the sun, can it be washed or does it need repainting?
A. If the paint has not signs of blistering or defects it may be possible to wash the cladding to remove the discoloured top layer. You could try using T cut (same as for car paint) to remove the top layer of paint. If it’s a large area a pressure washer may be quicker. If any paint comes off then repaint using Zinsser Allcoat or Dulux Metalshield.
Q. Areas of my cladding have rusted, what should I do to fix this?
A. Best to scrape back any surface rust and apply Flag rust converter, followed by a zinc phosphate metal primer. Then can be painted in chosen cladding coating.
