I've just finished building a workshop and we've decided to finish the front gable in a tudor style look, and match the same gable on the house. Initially I considered stucco and cedar planks for the cross members, but EIFS was recommended due to the low maintenance aspect of this finish.
I've heard all the bad press from initial EIFS installations so I want to know the correct way to prepare and install the stuff. Here are the descriptions of two quotes:
- Installation of 1/2" styrofoam on top of existing tyvek-wrapped plywood; application of brown coat and fiber mesh on top of styrofoam; application of finish coat on top of brown coat; 1 year company warranty with 5 year manufacturer warranty.
- Installation of 1" expanded Polystyrene Insulation Board on top of existing tyvek-wrapped plywood; application of the Prep-Coat (Skim Coat); application of Reinforcing Fiber mesh (0040); appliation of Prep-Coat (Leveling Coat); application of Acrylic Stucco Coating; 3 year manufacturer's material warranty.
Does anyone know which of these is the best methods of application? Also, what impact does the thickness of the styrofoam/polystyerene board have (aside from insulation value, which doesn't concern me as these gables are over an attic space.
I am looking for a durable, maintenance free finish, Great Lakes region climate.
If anyone knows of a good FHB article on EIFS, let me know. I haven't seen one yet.
