Question: how long do i have to wait to paint stucco?
Answer: A:Answer Until recently, you had to wait one to two months for the stucco to cure properly. However, new-generation masonry primers speed up the process considerably. For instance, Loxon Exterior Masonry Primer from Sherwin-Williams can be applied as soon as the stucco is hard, dry and at a pH level of less than 13.
