PAINTING A PALISADE FENCE
29 Jan 2016
To protect and decorate a palisade fence exposed to weather conditions is quite a task which requires extensive preparation and an adequate paint system, particularly in order to obtain the required product performance for at least the next 7-10years. Asking for a 20- year maintenance free system is a bit optimistic when considering the harsh weather conditions in South Africa.
(LIFE EXPECTANCY 1-3 YEARS) – APPLICATION BY BRUSH
Remove all loose,flaking paint using a steel brush and scrapers.
Degrease and remove chalking by abrading the surface with a scouring pad and a degreasing agent (general purpose cleaner).
Rinse off with cleaning running water.
rime all rusty and bare surfaces with two coats of a grey anti-corrosive metal primer at a spreading rate of 6m2/litre, allowing 4-6 hours drying time between coats.
Perform a measle corrosion test to confirm sufficient primer has been applied. Measle test: If tiny brown spots appear, apply a further coat of anti-corrosive primer to cover these spots.
Apply two coats of an exterior pure acrylic wall paint or pure acrylic roof paint. These products will retain their colour for a year or two longer than a high gloss enamel paint.
If you are serious about the lifespan and performance of a paint system, the job should be done as follows:
Make sure you wear safety equipment to protect eyes and hands when using a paint stripper. Strip all the existing paint from the palisade using a chemical paint remover or a heat gun, or, if you can, find a company to assist you with sand blasting the palisades.
After stripping the paint, remove the old residue by abrading the surface with a scouring pad and an alkaline degreaser, such as a general purpose cleaner, and rinse with clean running water.
Apply two coats of a grey anti-corrosive metal primer at a spreading rate of 6m2/litre, allowing 4–6 hours drying time between coats.
Note: perform a measle corrosive test to confirm that sufficient primer has been applied.
Apply two coats of water-based, high gloss enamel at 6m2/litre, allowing 4-6 hours drying time between coats.
Note:This has a very good colour retention, non-chalking, non-yellowing and excellent flexibility properties. The life expectancy of this product is approximately 10 years, if the preparation and priming is correctly done.
Note:The compressor and spray gun cannot be used to apply the above product as you will not attain the correct dry film thickness. This equipment can only be used to apply solvent-based coatings like quick drying primers and quick drying enamels, which will not give you the expected lifespan you require. The job can be done using airless spray equipment.
