I have a typical Southern California tract home of stucco with wood trim. I want to update the exterior and change the color. What are the pros and cons of simply painting the stucco and wood? I have been approached by a company selling a product called Texcote CoolWall. They claim that water will undermine the paint on the stucco and it will flake off in 3-5 years. However, they are trying to sell their product. Any comments, good or bad, about the CoolWall product? It is more expensive than painting but claims to have a 25 year limited warranty (labor not included). Is a color coat re-stucco a better option?
Comments welcome. Thanks

BobD, Tex-Cote is a recognized member of the build green council. I really don’t think that there would be any downside to their product. I have read several reviews on this product, and it really sounds like the real deal. I can tell you here in the Midwest, anything that would last longer than 3-5 years would be looked at with very favorable eyes.
They claim up to a 40 degree drop in wall temperatures once the product is applied. Here is a quote from Architect Magazine,
“TEX-COTE’s COOLWALL coating systems are formulated to reflect the sun’s heat and reduce heat build-up on exterior walls. This low-VOC formulation does not change the wall surface’s color. Its reflective properties can cool a building up to 40 F (22 C). Because its painting cycle is longer than other paints, COOLWALL reduces the environmental impact of repainting.”

Does anyone know the best way to paint a stucco house. I live in Florida where there is lots of mold and moisture. I’ve been told to start out by cleaning off the mold, then use something call seal crete. After that prime and paint. What type of paint would be the best, long lasting and mold resistant? Is there a set procedure?

Well refinishing Stucco is a complicated business and filled with opinions depending on where you are and what kind of “stucco” is actually in use on your home.
Oldworld Stucco is Lime based plaster type of substance
Stucco applied after 1900 is typically a cement based product
Modern stucco is typically a siding type of material with a backer board of various materials with a thin film of stucco looking material made from cement or plastic formed to look like stucco.
I have learned this after buying a 1860 Stucco house in Wisconsin, The house was pressure washed scrubbed and repainted the year before I bought it with a latex enamel for cement and 1 year later it was all peeling off in huge sheets. I have been researching this refinish for almost 2 years and I have found old school and cement stucco houses with freeze thaw cycles should never be sealed with a waterproof paint as when it freezes outside the water vapor inside flows thru the walls and gets trapped behind the paint and then freezes pushing the paint free of the surface causing the paint to peel.
Old school plaster as well as cement based stucco must be painted with a breathable finish that can allow moisture to pass thru it or it will peel off.
We have chosen to go back to a limewash finish for our home and after much discussion with major paint company spokesman and old time stucco workers as well as historic restoration folks I think this is the right choice. I assume there are as many opinions about this as there are people but I have looked at dozens of refinish projects in my area of the country and the ones that relly seem to last are the limewash jobs.
We have blasted the whole exterior of our home with corncobs to remove the failed finish and will begin refinishing ths Saturday.
One thing I can tell you is to research your homes finish and your environmental conditions carefully before deciding on a finish because most painters in my area are fully sold on the latex enamel finish for everything because that is what they use with great success on 99.7% of their work, your stucco home is a different animal and need to be treated in a different manner than most other home surfaces.
I did read alot of material put out by the national park service as to what is acceptable for use on restoration
of historic buildings the park service is responsible for and it was a real eye opener. I think these people have a wealth of historic experience taking proper care of some of the oldest buildings in the country.

We painted our stucco 11 years ago, and it has held up beautifully. We live 2 blocks from the Pacific, and have had no problem. We used Behr from Home Depot, and sprayed it on after a powerwash with TSP. The original wood on the other hand had to be completely replaced – dry rot.

As I said it depends on your weather patterns and locations what you need to use. Here in Wisconsin we typically spend at least 40 days a year under 0 Degrees and many at -20 below zero. and here the painted mortar based stucco was a disaster. My house had the same pretreatment of powerwash, scrubbing with tsp and a final power rinse and the following spring 1/4 of the paint was laying in the yard.
I wish it would have worked here as well as it did for you folks, would have saved me tons of money and time this summer.
I am now finished with my limewash repaint and I love it!!
Looks much better than paint and no peeling because it’s actually become part of the wall now.
