Interior/Exterior Finishes

One of the final steps in the AAC building process is choosing one of many finishes. Stucco or stone for the exterior is highly recommended for not only the look but longevity of the block. Pictured above is a job completed by Northwest AAC, showcasing stucco as the exterior finishing application. Stucco will not shrink, rot, or need costly maintenance as a standard wood finish would. Traditional wood or other sidings can also be used, but we highly recommend stone or stucco for the exterior finish to reap the full benefits of the aerated autoclaved material. 

Interior finishes are used to enhance the aesthetics and durability of AAC. They should be compatible with the underlying AAC in terms of thermal expansion and modulus of elasticity and be vapor permeable.  Some interior finishes include plaster, gypsum board, acrylic-based coatings, and tile.
