  • 2. Guest House--Front Elevation Front elevation of guest house/second garage before windows on foundation were padded out with EPS board and PVC accessories/lath were installed over upper level of wood framing. Window nailing fins padded out with expanded poly-styrene (EPS) board and bead/lath installation over wood framed walls.

  • 20. CONCLUSION: As this report illustrates, the exterior stucco wall system is complete on all elevations. As our lath/bead stage report indicated, the applicator employed PVC foundation weep screed at the CMU/framing intersections as required by ASTM to allow for water egress. After several discussions with builder, he insisted the stucco contractor omit control joints installed vertically off openings fro aesthetics. After consulting the SMA manual, the applicator chose to install reinforcing lath butterfly strips off the corners of openings. This, in conjunction with the 1/4" engineered joint around the perimeter of windows and doors, will help control cracking and preserve aesthetics. PVC accessories and 2.5 self-furring diamond lath were installed to all framed walls and arches as required. The scratch coat is fiber reinforced to add additional strength to the plaster over wood framed walls. The texture chosen by the owner and designer was a soft adobe. Samples were provided on the CMU garage wall and approved by the appropriate parties. After numerous discussions with the framing contractor , we agreed the front entry arches had to be corrected to rectify framing inconsistencies. The remaining arches were double beaded in some places with a regular and wide flange corner bead. Applicator was able to achieve a consistent arch through field adjustments, but the main entry had to be removed and replaced. There are intersections of dissimilar materials which require an ASTM 920 approved building sealant (Vulkem or equivalent). to prevent water ingress. It is critical that these areas be properly sealed in order to protect the structure. They should include: 1- Wood fascia/stucco intersection 2- Back and underside of ALL kickout flashings installed at sloped roof/vertical wall intersections. 3- Deck intersections 4- Penetrations through system (i.e. electrical, plumbing etc.) 5- Around perimeter of ALL openings where 1/4" gap is present. The ¼” gap left around windows over wood framing should have a 3/8” soft cell backer rod installed into the gap before the engineered sealant joint can be completed. The rod must be 25% larger than the joint size so it stays snug and does not move (hence 3/8”). The rod is critical to prevent three-sided adhesion and subsequent adhesive/cohesive sealant failure. 6- Around all exterior lighting attachments (and all other attachments through system). 7- Any areas which may allow water ingress into the building envelope.
  • 21. Representative photographs illustrating design and construction details have been included in the "photos" section of this report. EHS will perform a follow up inspection in six (6) months to evaluate the system performance and condition. We will submit a report indicating our findings and any issues which need to be addressed. If you have any questions or comments, please feel free to contact our office. Respectfully, Project Supervisor
