These comments are for general information only and are not intended to be relied upon as a guide for design, construction, or inspection of EIFS. Although every effort is made to ensure that this information is timely and correct, the responsibility remains with the designer, specifier, homebuilder, general contractor, and/or installer for specific applications. The specification, design, and construction of all EIFS must comply with local building codes and standards, applicable compliance reports and the individual manufacturer's system requirements. The successful performance of EIFS cladding is dependent upon the proper design and construction of the adjacent materials and systems of the structure.

 

What types of warranties are available with EIFS?

A variety of warranties is available, depending on the system installed and per the manufacturer's requirements. Samples of the warranties are available on request from the manufacturer.

 

What type of maintenance is required for an EIFS?

Periodic cleaning is suggested to maintain the EIFS appearance. Sometime repair of impact damage or punctures of the EIFS are necessary to restore surface integrity. As with all claddings, abutting elements such as sealant and flashing should be periodically inspected and maintained.

 

How can you clean the finish coat?

EIFS manufacturers provide procedures for cleaning for specific systems. Periodically EIFS finishes may need to be cleaned to remove dirt, algae (usually green stains on the surface of the finish), or mildew (generally black stains that look like dirt) that can accumulate on the surface. Basically, mild cleaning detergents, and low water pressure cool water, and a soft bristle brush. DO NOT USE THE FOLLOWING: cleaner that is solvent based; high water pressure; hot water; or wire brushes.

 

What materials can I use to recoat my EIFS?

For situations where you might wish to change the color of the building, or paint the building for some other reason, EIFS manufacturers produce several quality paint products (acrylic or elastomeric) to recoat and enhance the existing coating. Other alternatives are to use a quality, high-grade 100% acrylic exterior grade paint. Before recoating, appropriate repairs should be made and the surface should be cleaned to remove any surface contamination.

 

Whom do I contact if I need repairs?

EIFS manufacturers provide a "distributor locator" on their website to locate the distributor nearest you. The distributor can assist you in locating appropriate qualified contractors.

 

How long should EIFS last?

If properly maintained, the cladding will last the life of the building. Initial EIFS walls were installed in the late 1960s and most are still in service as of this writing (2006).
