And use TESCON PROFIL if you want to leave beams exposed. The fleece face of the TESCON tapes can be plastered over. Use with primer at masonry or plaster walls. With it's split release paper you get 2" on the wall and 2" on the joist. At 4" wide, VANA 100 gives you enough width to make the job easy. When to use: When you want to use the same tape that you're using for all the rest of your building.

The only tools you'll need are a utility knife and the Pressfix.Īdditionally the CONTEGA fleece can be plastered over if applied to a solid substrate like concrete or brick. The fleece backing connects easily to plaster, and the 3" width with dual release strips makes it the right fit for both efficacy and precision. They might require additional CONTEGA HF adhesive caulking in check marks of joist. They typically don't require a primer (even on masonry) due to SOLIDO adhesive and the flexibility of the tape backing. When to use: The SOLIDO tapes are the most adaptable of all the options. Method of Connection: Full-surface adhesive with multiple release strips. Interior/Exterior: EXO for Exterior / SL for Interior Vapor Permeance: EXO = 5 perm / SL = 1.2 perm It's possible to do quickly and effectively with methods that work for you. The solution for durable airtight connections is to use systematized tape connections that can be optimized for a one- or two-person job. Throughout the seasons, fluctuating moisture content and temperatures result in fraying mortar, cracking compound, moving wood and shrinking caulks. You need long-term airtightness that can compensate for the expansion, contraction and settling of the structure. And even if it looks tight on the day of installation. They leak even if they are double, triple or quadruple wythe walls. Soffits, overhangs, sistered joists and brick walls all leak air - and not a little, a lot. Luckily, 475 offers robust solutions for the hard parts, along with guidance on methods and materials to make your air sealing job easier. If joist sealing is not considered in advance, it can be a major issue for high performance assemblies. If you add up the total inches of cracks around a building full of joists, you have possibly hundreds of feet of air pathways that will leak. Anywhere joists penetrate an air barrier - interior or exterior - you have a job that needs to be designed and planned for to be successful. Joists are tricky three-dimensional objects, when it comes to the air barrier. This Ecostruct project achieved 0.23ACH50 after this plaster job + airsealing joists with Tescon Vana and Tescon Primer RP. But connections to the joists need to be addressed. Plaster is a great airtightness solution for party walls.
