Exterior Wall Insulation and Finish System (EIFS) Polymer based exterior non-structural wall finish applied to concrete, masonry, stucco or exterior grade gypsum sheathing (such as Dryvit). System consists of a plaster base coat approximately 1/4" thick, and a glass fiber mesh embedded in the adhesive base coat. The base coat is applied over polystyrene insulation boards bonded to an existing flat vertical wall surface with adhesive. Costs shown are per SF of finished wall surface. These costs do not include surface preparation or wall costs. Add the cost of scaffolding if required. Add 50% to the labor costs when work is done from scaffolding.
For scheduling purposes, estimate that a crew of three can field apply 250 SF of exterior wall insulation and finish systems in an 8-hour day.
