When it comes to identifying the type of stucco system installed on your house, understanding the nuances and characteristics of different systems is crucial. In this comprehensive guide, I, an expert in building materials and stucco application with over a decade of experience, will delve into the details of various stucco systems, providing you with accurate and reliable information to identify what’s on your home.
The Role of Weep Screed in Stucco Identification
A key aspect in recognizing the type of stucco on your home is examining the weep screed. This component can reveal a lot about the underlying system. To determine the stucco type, measure the depth from the foundation to the stucco edge. Remember, this measurement includes the underlying plywood or OSB beneath the stucco lath.
- A Three Coat System typically has a total depth of about 1 and 1/4 to 1 and 3/4 inches, including the siding, which is usually 3/8 inch thick.
- A One Coat System generally includes 1 inch of foam and 3/8 to 1/2 inch of cement, leading to a total depth of around 2 inches.
- An EIFS System (Exterior Insulation and Finish System) varies in depth, depending on the insulation board and specific manufacturer’s specifications.
- EIFS and One Coat Systems produce a hollow sound due to their thinner “mud” layer (about 3/8 to 1/2 inch).
- A Three Coat System sounds more solid, given its thicker application.
- Avoiding Damage: Exercise caution when using physical methods like tapping or measuring. Avoid excessive force which could damage the stucco finish.
- Professional Consultation: Always consider consulting a professional as a primary option. Their expertise is invaluable in ensuring accurate identification and preventing unnecessary damage.
- Understand the Risks: Be aware of the risks associated with invasive methods like breaking into the stucco. Such actions should be a last resort and performed by professionals.
