Why does your house stucco look faded out, mottled in color, dull and streaky when it is only three to five years old?

 

Faded & Mottled StuccoChances are good that you have a bad case of a condition called efflorescence and lime burnout. The difference between this condition and the common cold is the cold will go away. I am telling you this because there seems to be an epidemic of this problem throughout the valley. I am sure you have seen it either on your own home or on entire subdivisions.


The extreme conditions are evident by the fact that the stucco looks like it is thirty or more years old. You are probably asking yourself what causes this problem and what can I do to fix the problem. Well, I am glad you asked.

Here is the short version, although there may be other factors and issues at work, which accounts for most of the problems going on out in the real world. Everyone seems to be in a hurry today. We want faster cars, faster computers, faster food, faster service, etc. You will see advertising signs "one day service", "loan approved in one day", "delivered in thirty minutes or it's free", "3g", "4g", I suppose 5g is on the way. The same thing is going on in the home building arena; "sign today and move in your new home in three months". You say ok, what's wrong with that? Well, nothing if you are buying fast food, but it is a big problem if you are painting new stucco which has not fully cured
properly ( which almost none of the homes are fully cured and kept moist as they should be for 28 days). This means that the stucco ph level is what they call in the industry as too hot. Typically the painter paints the stucco soon after the stucco contractor has finished the job. Often the stucco is not primed properly, if at all, and if it is the product being used is often the wrong primer for painting hot stucco. The acrylic paints used for exterior stucco painting are made to breathe. Moisture is constantly going through the paint membrane to the stucco substrate and drawing back out as it dries from the inside out. This constant in and out of moisture vapor draws calcium and mineral deposits, commonly called efflorescence, and brings with it lime from the stucco.


Once this condition is in effect it is hard to stop the process. Many professional painters still think that simply power washing the stucco and re-painting it with good quality paint will do the trick. I hope you have not experienced this as the condition will often be back in as little as one to two years. This leads to a waste of time and money.

The solution is to talk to an expert who understands the problem and who can specify the proper primer as well as the proper finish paint. This is not an easy fix as most so called industry experts are not aware of the problem or do not have the product to solve your problem. My recommendation is ask questions of your industry expert and see if they seem to be aware of this problem. Ask if they have other homes which you could look at or get a referral of someone whom you could talk to regarding this problem.
