The only reason to use elastomerics is if you have a water problem. ie: wind driven water penetrates the stucco and makes it into the wall cavity. Unless you have this issue - I would avoid elastos because: 1. They are applied very heavily - and as such don't go too far - plus which they can be 1/3 again the price of a good 100% acrylic paint - so look to material cost being about 50% more than regular acrylic XT paint. 2. Painters often don't have the equipment or the skill to spray these products - they don't apply like regular paint - they are very thick (need a larger sprayer) and if they are not applied at the proper thickness - they don't work. 3. Elastomerics tend to mildew. In order to be flexible - they must be soft - this softness allows dust and dirt to stick to the coating - and along with the dust and dirt come mildew spores. Elastos can be a constant maintenance issue. So unless you have a water issue......I would stick with a very good quality 100% acrylic latex exterior paint - in a satin finish. ICI Dulux and ICI Fortis are two great products I am familiar with. These are available at ICI Paint Stores. I sold elastos for years in S. Florida - I know from whence I speak. Mr. Paint |
