Cementitious color coats verse acrylics color coat
Good question, I don’t know. Just kidding,
Depends A 3 coat traditional stucco system with a cementitious finish should last over 100’s of years of course the colors will fade in the sun and through the years with many, many season of rain especially for months at a time the ground will saturate and move this is normal, however this will cause hairlines cracks, mind you these cracks do not mean a home is leaking it simply means after many season’s this will occur no matter where in the whorl you live. Also traffic wind, doors and window being slammed or shut hard will cause hairline cracks too, and this is just the tip of the iceberg. These cementitious color finishes will darken like a brick because they are maintenance free. (Never needs painting) But stucco does not rot like wood, too many other benefits to name.
Now acrylic finishes are basically Acrylic paints with sand and color, this means they can flex more than a cementitious color finish and when they get wet they do not darken as they don’t absorb water
(at least not for about 25 years and even then only a bit.) I usually recommend acrylics on hilltop homes where the winds and the rains are brutal, (usually about
50 to100 miles an hour) the rain mixed with high wind, will add movement to any home.
You will however pay more for the acrylics, do the benefits outweighs the costs I believe so in certain situations they do.
