Need to known about chalking

Chalking is the breakdown of a outside layer binder due to exposure to the ultraviolet (UV) rays of the sun. Causes included as below:

- Failure to correctly prime and seal a surface.

- Excess thinning the paint.

- Spreading the paint too thinly.

Oil-based paints are additional prone to chalking than acrylics. While it is normal for paint to wear over time, extreme chalking must be resolved to ensure that the new coat of paint will bond.
