Shawn Miller Posted July 6, 2010 Report Share Posted July 6, 2010 Our house is 3.5 years old and we are having rust coming through the 100% acrylic Stuccoat stucco. Why would this happen? Quote Link to comment Share on other sites More sharing options...
Marc Posted July 6, 2010 Report Share Posted July 6, 2010 Do you know the name of the manufacturer that produced the system used on your house? Some manufacturers use silica sand for texture which sometimes contains iron particles and will rust. What pattern do the rust stains make? Any photo available?

As Marc said, photos would be helpful.. It could be several things causing it and a photo might help. Quote Link to comment Share on other sites More sharing options...
Shawn Miller Posted July 6, 2010 Author Report Share Posted July 6, 2010 The product is called an elastomeric F-14 Western Stucco products and an Eisenwall crack resistant base coat. The cracks with rust look like the stucco is leaching. It is rusting on the corners of the house, around some of the windows and then on some of the big wall where the weather really gets to it. I will take some pictures! Thank you! Shawn Quote Link to comment Share on other sites More sharing options...

Shawn Miller Posted July 6, 2010 Author Report Share Posted July 6, 2010 Is this usual for 3.5 year old high end construction? Quote Link to comment Share on other sites More sharing options...
hausdok Posted July 6, 2010 Report Share Posted July 6, 2010 Hell no! It sounds like the contractor used sub-standard fasteners and lath. One Team - One Fight!!! Mike Quote Link to comment Share on other sites More sharing options...
kurt Posted July 6, 2010 Report Share Posted July 6, 2010 Is this usual for 3.5 year old high end construction? Actually, it is sort of "usual". There's a whole lot of "high end construction" stucco that's really messed up. Several of the engineered claddings don't perform in the manner intended for multiple reasons, almost all having to do with failure caused by moisture. Personally, I'm not a fan of elastomerics. I can imagine a lot of problems simply because it's an elastomeric. I've never seen one work satisfactorily. Not to say it can't be done, but I've never seen it done, and I've seen a lot of elastomeric coatings. Quote Link to comment Share on other sites More sharing options...
robert1966 Posted August 4, 2010 Report Share Posted August 4, 2010 I could agree more sound like lath issues due to faulty or shabby installation. Could be flashing or other penetration problems occurring from above. Quote Link to comment Share on other sites More sharing options...
