The Foster® construction products are designed for application to building materials at the time of construction and remodeling projects to protect materials from water penetration while offering a product that is highly resistant to mold growth.

The products are excellent for application to a variety of building materials and a range of locations prone to high moisture content that can lead to mold growth. Foster® 42-42™ is the perfect product for use on surfaces not easily seen, such as wall cavities, ceiling/floor joists, crawl spaces and attics. When tested under the rigorous parameters of ASTM D-5590 it exhibits no growth.
