Hi all, I hope I'm posting to the right section. I'm getting ready to repair some stucco cracks on my 1946 Ranch. The cracks are up to an 3/4" wide in a few places.
In all the stucco patching how-tos I have found, the repairperson is using a modern type compound like silicone caulk or DAP stucco repair compound to fix the cracks, and then painting over it. The trouble is, our house is not painted--it is natural stucco color, a light tan.
I understand that old-fashioned stucco goes on white and eventually weathers to light tan. A repair done a couple of years ago attests to this (white patch turned tan), but I don't know what product was used. Do modern polymer stucco patch compounds turn light tan like this, or do I need real, old-fashioned stucco? And how long does it take to change colors?
stucco can be applied in many natural colors depending on the type of gray portland cement or trinity white. different colors of sand mixed in can change the finished look also (white, yellow, orange...). dyes can be used too. maybe you should put up some pics for us to look at.
I don't know what was used that turned color over time, but that's not what usually happens. If you use a tinted stucco, it stays that color.
Cracks in stucco that are 3/4" indicate a structural issue to me. Materials do not separate that much without something else going on underneath.
