Synthetic Stucco, also known as EIFS, is a multi-layered exterior finish that’s been the mainstay of building in Europe since after the second world war. EIFS or Exterior Insulation and Finish Systems was the better system for buildings demolished during the war. Most of the repairs to European edifices were to buildings made up of concrete, stone or brick including some other resilient substances. In the United States EIFS was introduced in the 1980s initially in buildings occupied by businesses. After that it was applied as an external finish for residences usually those with wooden frames.
There are three layers to EIFS Stucco the first layer is the inner layer which is a foam insulation board attached to the outside wall surface, frequently with a bonding agent. The middle layer is utilized at the top of the insulation then toughened with a glass fiber mesh. It’s usually made from a polymer and cement base coat. The outside or exterior layer is an uneven finished coat. The merging of these three layers form a non-porous covering. In spite of this, if moisture trickles inside it can become snared behind the layers. With no escape, steady contact to dampness can cause rotting in wood and other susceptible substances inside the home. EIFS Stucco was well equipped for usage as an outside casing for concrete and stone, however, for wood it became a problem which resulted in plenty of class action lawsuits in the United States.
. Openings like window frames and doors should be sealed to thwart moisture from leaking behind the EIFS
. Foam should always be above grade
. Objects that penetrate through the stucco should be sealed
. Keep gutters clean and positioned to drain away from the house
A very significant point to remember is that no humidity should leak behind the EIFS. Indications of EIFS problems include mold or mildew on the inside or outside of the home, engorged wood around window frames and doors, peeling paint and cracked sealant or EIFS.
These days, innovative EIFS methods incorporate drainage systems to assist in keeping dampness from getting caught behind the shell. It’s always good to consult with an experienced home builder about up-to-date EIFS techniques.
