How long can Caviseal be exposed to the UV rays of the Sun?
Caviseal will burn over and change color as well as lose a 1/16 of an inch in the first month. After it burns over the degradation action slows and you will lose about an 1/8″ in four months. However we want it to burn over some because it creates a hardened shell on the face increasing its permeability and moisture penetration characteristics.
