Full Name

ICC-ES AC11 – Acceptance Criteria for Cementitious Exterior Wall Coatings

Scope

ICC-ES AC11 outlines the requirements for evaluating and accepting cementitious exterior wall coatings. These coatings are typically used to protect and enhance the appearance of exterior walls of buildings. The scope of AC11 includes the following aspects:
  • Materials: it covers various cementitious materials used in these coatings, such as Portland cement, lime, aggregates, and admixtures.
  • Performance: AC11 outlines the performance criteria for these coatings, including their resistance to weathering, moisture penetration, cracking, and other factors that affect their durability and effectiveness.
  • Testing: it details the specific tests required to evaluate the coatings, including those for adhesion, water resistance, flexural strength, and freeze-thaw resistance.
  • Installation: AC11 addresses the proper methods for installing these coatings to ensure they perform as intended and adhere to the substrate.
By adhering to AC11, manufacturers can demonstrate that their cementitious exterior wall coatings meet the standards for quality and performance set by the International Code Council Evaluation Service (ICC-ES). This can help ensure that buildings using these coatings are durable, safe, and aesthetically pleasing.
