The 2021 IBC and IRC code improvements to address the above principles are shown in Figure 2 below (only the IBC text is shown; the IRC text is identical). Clarification - Accessible Door Hardware - IBC 1010.1.9.1 As mentioned in a prior January 2020 EEBS article (2021 I-Codes Adopt Major Energy Efficiency & Building Science Advancements), many advancements forthcoming in the 2021 ICC family of codes (energy and building codes) were overviewed with the intent to address these advancements individually in future articles. The individual layers shall be installed independently such that each layer provides a separate continuous plane and any flashing, installed in accordance with Section 1404.4 and intended to drain to the water-resistive barrier, is directed between the layers. Published July 1, 2019. With a substrate of concrete or concrete masonry, is it necessary to use lath? Air Barrier Systems. We provide residential, commercial and third party inspections as well as consulting services to homeowners, building … The Drainage Plane.”. Code References •The 2008 Edition of ASTM C 1063 is referenced in Ch. Title: SMA show flyers Author: G4 Created Date: Well, here’s the first installment and it addresses some very useful improvements and clarifications made to the Portland Cement stucco water-resistive barrier (WRB) provisions. The weather resistant barrier (WRB) must be installed per Sections R703.6.3 of the Florida Building Code Residential and 1404.2.1 of the Florida Building Code. The Drainage Plane, continually seeks to improve the value it provides, Editor's Message: Three Lessons Learned from 2020, President's Message: We Are Technology Brokers. stucco according to local building codes. Your inspector may want to see an additional layer of building paper or asphalt felt on the exterior side of the Home Slicker Stone and Stucco, because the wording of the building code gives your inspector that latitude.

Unless it’s very hot, dry and/or windy, moisture on the wall together with that in the plaster is usually sufficient for curing. In a traditional successful approach, the reservoir cladding is back-ventilated to help remove the water vapor being driven inward as the cladding attempts to dry both inward and outward (see Figure 1). In the state of Arizona, every local jurisdiction is responsible for establishing and enforcing building codes.However, the Manufactured Housing Division, part of the Arizona Department of Housing (ADOH), maintains standards of safety and quality for all manufactured homes, factory-built buildings, and accessory structures. Inward Moisture Movement Due to Reservoir Cladding and Solar Radiation. 35 of the 5th Edition (2014) FBCB. In addition, there are two standards from the American Society for Testing and Materials (ASTM) that regulate the application of stucco: –2109.3.4.8 Exterior Finish - Adobe Construction –2510.3 Lathing and Furring for Cement Plaster (Stucco) –Table 2511.1 Installation of Plaster Construction –2512.1.1 On Grade Floor Slab Construction One of the following shall apply for dry (B) climate zones: 2510.6.2 Moist or marine climates. First, they allow traditional practices to be continued where they have been successful in the “dry” climate zones (see Section 2510.6.1 in Figure 2 and Figure 3 for the “dry” climate region). Stucco Finishes. If it is readily absorbed, then the surface is expected to bond well with stucco. As such, they have a great affinity for each other. This standard contain specific requirements for the materials, methods and quality control used in applying stucco, including approved thicknesses for different application substrates. This question probably arises because plaster is often attached to wall surfaces that have metal lath affixed to them. A bond break shall be provided between the water resistive barrier and the cement plaster (stucco) consisting of one of the following: 1. However, in this latter case, a separate bond-break or non-water absorbing layer must be applied over the foam sheathing WRB as shown in Figure 4 (i.e., the foam sheathing is used as the WRB, not as the intervening non-water absorbing layer). The cause is led by the inadequate building codes on stucco installation. Building Code (Title 16) Use and Occupancy Letters. The answer to question 3 is hard to pin down. In moist (A) or marine (C) climate zones, water-resistive barrier shall comply with of one of the following: In addition to complying with Item 1 or 2 of Section 2510.6.1, a minimum 3/16 inch (4.8 mm) space shall be added to the exterior side of the water-resistive barrier. The Washington State Building Code is comprised of several different codes. They agree on what constitutes “best practice” and develop standards to reflect that. Concrete masonry surfaces are both absorbent and textured, two things necessary for bond. SBC Magazine appreciates your input, and continually seeks to improve the value it provides to the market. A bond break shall be provided between the water resistive barrier and the cement plaster (stucco) consisting of one of the following: 1. Finally, in rainy climates, it is important to provide at least a small drainage gap and pathway to efficiently remove bulk water from rain intrusion through the reservoir cladding which would otherwise add to the inwardly-driven water vapor load. 2510.6.1 Dry climates. If you have any comments or corrections on this article, please email us and we can publish your comments. ASTM Standard C 926, Specification for Application of Portland Cement-Based Plaster, permits direct application of stucco to solid surfaces like concrete and masonry as long as bond is sufficient. This can result in elevated exterior sheathing moisture contents, and for buildings that are air-conditioned in the summer, condensation on the interior vapor retarder or high moisture contents in interior finishes. If contamination is present on the substrate surface, good bond is inhibited. For additional information, visit Continuous Insulation's Water Vapor Control web page.

Guests enjoy the Kitsap Conference Center, two hotels, fine dining, coffee shops, cafes and the Port of Bremerton Marina in the downtown Harborside area. The water-resistive barrier shall be separated from the stucco by a layer of foam plastic insulating sheathing or other non-water absorbing layer. 2510.6 Water-resistive barriers. It dampens the unit, reducing its water demand and the potential of premature dryout. 2014 FBC - Building, 5 th edition > 25 Gypsum Board and Plaster > 2510 Lathing and Furring for Cement Plaster (Stucco) JUMP TO FULL CODE CHAPTER 2510.1 General Exterior and interior cement plaster and lathing shall be done with the appropriate materials listed in Table 2507.2 and Chapter 35. On exterior stud walls, adhered masonry veneer shall be installed not less than 4 inches (102 … Denver Building Code provides minimum standards for building in order to safeguard public safety, health and welfare. Potential for bond can be quickly checked by a simple test: sprinkle the wall with some water to see how it absorbs. 2019 California Building Standards Code - Title 24 Education & Outreach. But, this also provides flexibility to use other materials like some foam sheathing products to serve as the WRB layer where approved for that purpose and also having a water-resistance equivalent to ASTM E2556 Type II. The Florida Building Code defines "stucco" as a Portland cement-based plaster mixed and applied according the ASTM C 926-06, "Standard Specification for Application of Portland Cement-Based Plaster." The entire surface must have uniform bonding potential or you can run into problems. Figure 4. Frame—Exterior walls of wood, brick veneer, stone veneer, wood ironclad, or stucco on wood. Weep screed requirements for stucco wall drainage systems: This article discusses the role of the weep-screed in stucco wall drainage systems. This gap also allows for what is known as “hygric re-distribution” (for more information please refer to see BSC article: “Drain the Rain, On the Plane. Learn more and access 2016-2017 archives here. Effective January 1, 2020. For other types of sheathing that are sensitive to moisture, it is recommended that the provisions aimed at wood-based sheathing be used, even though not required by the code. If stucco is to be painted, allow 28 days for curing cementitious products prior to painting. Archived 2005 Pikes Peak Regional Building Code Last Upload Date: 6/11/2018. Sound Exterior is a building envelope inspection company specializing in the inspection of stucco and EIFS (Exterior Insulating Finish System) claddings. This is generally not a concern with new walls. Building Code Standards on Stucco . Generally, stucco that is applied directly to solid surfaces is placed in two coats that together total 5/8 inch of thickness. Older walls may have bond-inhibiting characteristics, in the form of paint, sealer, or some other coating or dirt on the surface. Senturion I, II and III Florida Department of Community Affairs Florida Product Approval FL 13447 Texas Department of Insurance The water-resistive barrier shall be two layers of 10-minute Grade D paper or have a water resistance equal to or greater than two layers of water-resistive barrier complying with ASTM E2556, Type I. One-inch (25 mm) minimum thickness of cement grout shall be placed between the backing and the stone veneer. SDCI Closures, Service Updates, and Inspection Requirements. Order the 2019 edition of Title 24 from the publishers listed on the Codes tab. This practice will help to mitigate moisture issues that have occurred behind stucco and adhered veneers (e.g., reservoir claddings) in moist regions of the U.S. The building code specification recognizes that the principal long-term condition for corrosion protection is achieved by full stucco embedment of the stucco metal base. The cold-formed steel framing members shall have a minimum bare steel thickness of 0.0428 inches (1.087 mm). The distinct embedment characteristics of wire lath and expanded metal reflect the differential zinc coating weight requirements. Foam sheathing continuous insulation is commonly used for this purpose and, in colder climates, it must be used in the appropriate amount together with an interior vapor retarder to effectively control wintertime outward vapor drives (more on this to come in a future article which will discuss coordinated advancements in the 2021 IBC and IRC water vapor retarder provisions; in the interim please refer to the wall calculators, Research Report 1410-03 Assessment of Water Vapor Control Methods for Modern Insulated Light-Frame Wall Assemblies and Research Report 1701-01 Model Moisture Control Guidelines for Light-Frame Walls: A Building Code Supplement for Builders, Designers, and Building Officials). These improved provisions do two very important things consistent with the above-described principles. (Construction Code 1) Joisted Masonry—Exterior walls of masonry material (adobe, brick, concrete, gypsum block, hollow concrete block, stone, tile, or similar materials) with combustible floor and roof. In addition to complying with Item 2 of Section 2510.6.1, a space with a minimum drainage efficiency of 90% as measured in accordance with ASTM E2273 or Annex A2 of ASTM E2925 is added to the exterior side of the water-resistive barrier. Where cement plaster (stucco) is to be applied to lath over frame construction, measures shall be taken to prevent bonding between the cement plaster and the water resistive barrier. Stucco Joint Sealant. The discussion includes a definition of weep screed, citation of building codes relevant to weep screeds, and references to expert sources on weep screed requirements & specifications for various stucco wall drainage systems. This prepares the unit surface to absorb paste from plaster. When applied over a wood base a minimum of two layers grade D paper ASTM Standard C 926, Specification for Application of Portland Cement-Based Plaster, permits direct application of stucco to solid surfaces like concrete and masonry as long as bond is sufficient. 2020 County of Los Angeles Existing Building Code (Title 33) Enforcement of the provisions of each Code begins on the effective date listed above for projects with an application date on or after their respective effective date. People often ask us if stucco, or portland cement plaster, will adhere to concrete or concrete masonry. Immediately prior to plastering, the wall should be pre-wetted. Stucco is made from the same materials as concrete and concrete masonry. Learn more about the steps you should take before inquiring about a U&O letter for your project. The Seattle Building Code (SBC) provides minimum requirements for design and construction of new buildings. OTHER CODES AND ORDINANCES. In another successful approach commonly used with stucco, inwardly-driven water vapor can be blocked by placing an “intervening layer” of low vapor permeance “non-water absorbing” material between the reservoir cladding and the remainder of the wall assembly. Benefits of traditional Portland cement-based stucco Review of building codes and ASTM standards Research reports on water intrusion Design features required to managing water intrusion and stresses in stucco Specification and detailing requirements and recommended best practices 1 … These are two small docu- ments with prescriptive requirements that are easily read and understood. 2019 California Building Standards Code, Title 24, California Code of Regulations.
