Here's some more information I've found. (Not for gluing Mylar, though.) Am going to experiment soon with the Liquid Nails product mentioned. This week or next. Will report back.
"...The manufacturer of the polyiso I am using (Rmax thermasheath -3) recommended Liquid Nails heavy duty construction adhesive (LN 903/LNP-903 - latex base). I contacted Loctitie (they makePL-300 for foamboard) but their representative stated that PL-300 does not work well with foil faced polyiso, nor do any of their other products. Siga Primur has been recommended as a superior product for my application, but this product costs an arm and a leg." -- http://www.greenbuildingadvisor.com/community/forum/energy-efficiency-and-durability/39868/foil-faced-polyiso-and-construction-adhesive "Panel & Foam Adhesive (LN-609) This fast-bonding adhesive is like an extra set of hands providing a sure hold, precision placement and less nailing. Excellent as a wall adhesive, it offers 10 minutes of working time and an impact-resistant bond." -- http://www.liquidnails.com/products/bonding-adhesive-LN609 "Key Features Will not stain Instant-grab formula Reduces nailing Flexible and strong, water-resistant bond Retains precise placement Impact resistant Contributes to LEED® certification Contributes toward NAHB National Green Building Standard™ certification of the structure Recommended For: use as a wall adhesive for paneling, foamboard, MDF board and paneling, wainscoting, corkboard, wood, foam and plastic molding, and all types of insulation board. NOT Recommended For: uses other than paneling, molding, foamboard or EIFS installation, or use between two non-porous surfaces. Available Sizes 10 oz. cartridge Coverage 10 oz. cartridge covers 32 lineal ft. Max VOC 43 GPL Specifications ASTM C-557 *Please note that the typical dry time for most construction adhesives is approximately 24 hours. This may vary due to temperature, humidity amount of product applied and surface porosity." -- ibid "Surface Preparation All panels must be separated and conditioned to room temperature for 48 hours prior to installation. Preparation: Surfaces must be clean, dry and structurally sound before application of this fast-bonding adhesive. Cut and pre-fit materials prior to installation. Application 1. Cut nozzle at a 45? angle to desired bead size (marked on nozzle). 2. Puncture inner seal with nail or wire. 3. Adhere materials within 20 minutes of gunning fast-bonding adhesive. Due to panel inconsistencies, for best results, bracing and/or nailing may be required. Humidity may extend dry time of fast-bonding adhesive. Instant-grab method: Paneling — Apply 1/4" bead of fast-bonding adhesive approximately 1" from edge of panel around the perimeter. Apply two zig-zag 1/4" beads of fast-bonding adhesive in the middle of the panel. Press panel firmly into place. Remove panel from wall for one minute. Rejoin panel to wall. Molding — Apply 1/4" zig-zag bead of fast-bonding adhesive to back of molding. Press molding firmly into place. Starting at one end, nail every 12". Cleanup If this fast-bonding adhesive is wet, use water promptly. If the fast-bonding adhesive has dried, scrape it away, then remove residue using a cloth dampened with mineral spirits." -- ibid On Saturday, June 17, 2017 at 3:31:04 PM UTC-6, Steve Upstill (Swifty) wrote: > > Due to overenthusiastic velcro, some of the foil on my polyiso panels has > come loose.
