Is your paint work looking a little dull?
Premature fading often occurs on surfaces with a sunny exposure. It can also be due to chalking of the coating and can be caused by any of the following:
- Using an interior grade of paint for an outdoor application
- Using inferior quality paint
- Using a paint colour that is particularly vulnerable to UV rays (most notably bright reds, blues and yellows)
- Tinting a white paint not intended for tinting, or over tinting a light or medium paint base
- Lower than prescribed dry film builds application
Colour fading is irreversible once it begins to occur and the colour can often become quite irregular or patchy in appearance. To eliminate the effect the entire surface will need to be pressure washed and/or scrubbed with a non-metallic scouring pad to remove all surface contaminants and chalking prior to repainting.
To minimise colour fading:
- Dulux Weathershield is recommended as it exhibits UV protection and high performance colour durability
- Select lighter colours as they absorb less heat and UV radiation
- Ensure paint is applied at the recommended spreading rate (correct dry film build)
