Cladding Paint

What is cladding paint?

Cladding paint is a type of paint that can improve the appearance of the surface and provide it with long lasting protection. All of our specially formulated cladding paint is fast drying and anti-corrosive and there are multiple colours available.

How to paint cladding?

The below steps are what you will need to do to paint cladding:

Preparation: Clean thoroughly with Johnstone’s Cleaner and Degreaser after removing all loose and flaking paint, salts etc. Wash down with clean water. All bare areas of steel/aluminium must be suitably prepared and spot primed with a primer such as Johnstone’s Quick Dry Zinc Phosphate Primer.

For steel: Prepare surface and prime accordingly. If overcoating an existing paint, ensure the surface is clean and dry. Special precautions should be taken during surface preparation of paint surfaces from before the 1960s over wood and metal as they may contain harmful lead.

Application: Stir thoroughly before use. Apply by brush or roller. If more than one can of a colour is to be used in the same area, intermix before use.

Cleaning: Remove as much product as possible from application equipment before cleaning. Replace lid firmly. Clean equipment immediately after use with TC2 Thinner and Cleaner. Some local authorities have special facilities for the disposal of waste coatings. Do not empty product into drains or watercourses.

How to paint wooden cladding?

Here are our recommended steps of how to paint wooden cladding:

First, scrub the surface with the stiff hand brush. Then clean the area with a solution of water and trisodium phosphate (TSP). Do not use it on bare wood, as this solution is erosive. Also, remember to always wear safety goggles and rubber gloves when using it.

Scrape any loose paint, and use a power sander to remove large areas of paint. It is best to work in 3-foot sections at a time. Move the sander horizontally across the top of a board, and horizontally along the underside of the lip.

Fill any holes or other imperfections using a putty knife to apply vinyl exterior spackling paste. Wait until the spackling paste is dry before moving to the next step.

Sand the panelling until it is smooth using a sanding block or a palm sander with 100-grit sandpaper. This will take the sheen off the finish, which will allow the paint to adhere to it better. Wipe away any residual dust.

Finally, use a roller with a medium nap to paint the wood paneling. The medium nap roller will allow you to fill the vertical grooves in the paneling, but also leave a smooth surface. Prime the paneling with a latex, stain-blocking primer. We advise having your primer tinted with colorant similar to the finished paint to achieve an even coverage. Once the primer has dried, finish it with two coats of latex wall paint.
