Supplies and Equipment Supplies will vary depending on wall substrate and adhesive choice • Crane Composites Standard FRP • Adhesive - Crane Advanced Polymer Adhesive (R53829) or Crane Fast Grab Adhesive (R53828) Refer to page 5 for assistance in selecting the appropriate adhesive • Crane Composites Laminate Roller (Part # R50ROLLER) • Crane Composites V-notched Trowel 3/16′′ x 1/4′′ x 5/16′′ (Part # R50TROWEL) • Cleanroom Wall System Seam Sealant - 7555 Urethane Sealant (R53827) • Applicator - Pneumatic D
NEW GYPSUM BOARD OR DRYWALL New gypsum should not be painted or primed. Tapered joints need only a fill and taped coating using a setting joint compound. A finish coat is not necessary or desirable. Any extremely uneven areas should be filled. Remove all drywall dust. PLYWOOD Plywood walls must be flat and even, and warped plywood should be removed and replaced. Solvent-Free adhesive cannot be used on any installation over pressure treated or fire-rated plywood.

Cutting Instructions POSITION PANEL FACE DOWN ON A COVERED WORK AREA When cutting with a circular saw, position the panel so that the saw blade enters the back side of panel first to avoid chipping or damage. (Figure 3) Radius Corners of Cut-Outs Optional Shear CUT-OUTS The inside corners of all cut-outs must have a radius of at least 1/8” (3.2 mm). Failure to radius corners may result in stress cracking. For pilot holes, a 1/4” (6.
Panel and Seam Sealant Sequence All panels are installed prior to the seam treatment. Before caulk and sealant can be applied, installed panels need to be adhered for at least 6 hours. Panel Installation Finish • • Use a laminate roller to ensure all air pockets are removed between the panel and the wall and to ensure a good bond between the panel and the wall. Start in the top corner of the panel away from the leading edge. Begin rolling down and out towards the panel edge without a molding.
Seam Sealant Workability Time 1/8” - 3/16” Bead Temperature (°F) 70 80 90 100 1 2 Time (Minutes) 3 4 5 6 7 8 9 10 Workable Suspect IMPORTANT INSTALLATION NOTE Seam Sealant workability begins at initial dispense Not Workable Apply Urethane Sealant to Seams/Joints General Process notes: 1. At end user discretion as to the number of operators used for the seam seal application process. A minimum of two operators is recommended. 2.
7. 8. Remove horizontal tape and begin next 3’ section. A good technique is to apply the sealant below the previous section and “bump up” the sealant into the previous section (Figure 19). Once the all sections of the wall are completed, remove the vertical painters tape.
Seams Around Doors and window Frames and Other Special Application Areas 1. 2. 3. Repeat process listed in Vertical Flat Panel Seams. Material should be dispensed into each seam at a rate such that the seam is completely filled with sealant but completed within the necessary open time for the sealant. As these seams typically have a larger gap, they may not be able to be filled by the sealant in one pass.
AN IMPORTANT NOTE ABOUT MOISTURE RESISTANT SUBSTRATES MOISTURE-RESISTANT GYPSUM VARIES TREMENDOUSLY, WHILE SOME OF THESE NEW SURFACES ALLOW MOISTURE TO PENETRATE, OTHERS RETARD OR TOTALLY PREVENT PENETRATION OF WATER OR SOLVENT.
