aDHESIVE FOR wood skiriting -

If you are a Contractor or sub, work with your project’s design team and LEED-APs to determine which products are suitable to your project. SCAQMD Rule 1168 (http://www.aqmd.gov/docs/default-source/rule-book/reg-xi/rule-1168.pdf?sfvrsn=4) defines product categories and describes which VOC limits apply. USGBC’s LEED Interpretations database (http://www.usgbc.org/leed-interpretations) includes rulings for IEQc4.1 that describe how that standard applies to LEED. To your specific questions: 1. I assume that “skirting” means baseboard or similar trim. SCAQMD-1168 defines “wood flooring adhesive” as one “used to install a wood floor surface” (parquet tiles, wood planks, or strips). This definition does not extend to baseboards. See SCAQMD definitions for “Multipurpose Construction Adhesive” or “Contact Adhesive.” Review product labels & manufacturer’s data. If recommended for these uses, the VOC limit listed under “Architectural” & “Specialty” Applications applies. 2. “Off-label” use is not allowed, so you can’t use a “rubber flooring” or “cove base” adhesive on wood baseboards unless the manufacturer recommends it for wood as well. SCAQMD-1168 states that, if a product is labeled for more than one use, the lowest VOC standard applies (except as in Item 3 below). 3. The “Substrate Specific Applications” are for adhesives not covered by the “Architectural” & “Specialty” Applications in the top part of the VOC table. If bonding dissimilar substrates together, the higher VOC limit applies. Therefore, if the product does not match any of the definitions for “Architectural” or “Specialty” adhesives, use the “Substrate Specific” VOC limits (30g/L, if gluing wood baseboards to wood or metal substrates, 50g/L, if to plastic foam or other porous substrate, or 70g/L, if to fiberglass).
