Self-adhered flashing tape ‘sticks’ to the substrate, or pieces of tape attach to one another to protect a building. A liquid-applied flashing forms a chemical bond with the substrate and any additional material it laps onto. Therefore, liquid-applied flashings can be viewed as fully adhered rather than self-adhered. Liquid-applied flashings become monolithic, and when they are tied in with liquid-applied air and moisture barriers, they become a component in a complete, monolithic system.
Flashings are an integral part of a building and should be given consideration during design and construction. Self-adhered flashings have been popular for many years, but these new products may be a better option in many cases. Liquid-applied flashings meet the same performance criteria, but are much easier to install.
Leaks are most commonly a result of installation error rather than product failure, therefore, it makes more sense to find a product that offers long-term performance and can be applied most easily. Keeping moisture out of buildings is a serious concern, but the products available today can easily overcome these issues.
