Painting on stucco


I have an older stucco house located near the coast on central California--Carmel. A contract was signed to have the house painted and the company came out and pressure washed the house in early November 2015. I was told that it would be several weeks before they would paint the house?

After the house was pressure washed, frosty weather came in, and then there have been intermittent rains since then. The painters want to come out this Monday (Jan. 25) to begin the prep on the house. This week-end the rains will come and go.

What am i to make of all this? What is the purpose of pressure washing? It has been 60+ days since it was pressure washed, the stucco walls are damp with rain water. I do not believe now is a good time to get the house painted. What are your thoughts?

Welcome to the forums!

About the only time you want masonry to be damp prior to painting is when it is super hot and dry - then misting the stucco with water will prevent the paint from drying too fast and not creating a good bond with the substrate. Otherwise you want the substrate to be dry prior to painting!

Depending on how busy the contractor is it is normal to wait a few weeks between pressure washing and painting. You always want to wait at least 1-3 days after PWing [depending on weather conditions] 60 days might be ok - is the exterior of the house still clean? If there was any chalk, did it all get removed?

As long as the stucco is dry and the day/night temps are acceptable - I'd be ok with painting the house BUT if the stucco is damp or the temps are too cool - it's better to wait.
