Paint crocodiling
Have you spotted patterned cracks in the surface of your paint film that resembles crocodile scales?
Possible Cause
This can be caused by several things:
The application of an extremely hard, rigid coating (such as an oil-based enamel) over a more flexible coating, such as a water-based primer.
Applying your topcoat before the undercoat is dry.
The natural ageing of oil-based paints as outdoor temperatures fluctuate. The constant expansion and contraction of the paint based on the temperature can result in a loss of paint film elasticity.
Solution
Old paint should be completely removed by scraping and sanding the surface. A heat gun can be used to speed up your work on large surfaces, but be careful not to ignite the paint or substrate. Then commence painting following instructions on the can.
The surface should be primed with a high-quality water-based primer and then painted with a top quality exterior water-based paint. Dulux recommends Dulux Weathershield® for a premium exterior paint.
