If there is a discrepancy at any time during the installation, STOP and contact LDI to resolve before proceeding. It is your responsibility to examine the goods and confirm the accuracy of the pattern and that color and yardage are satisfactory and as ordered. Cut material is not returnable. Check all roll tickets to determine if more than one run or dye-lot of the same pattern is to be installed. No claims will be allowed unless all instructions are followed. Install THREE strips, then stop and inspect the wallcovering. If satisfactory, proceed with work. If NOT acceptable or if there is a variation of color; stop hanging and contact LDI IMMEDIATELY. LDI will not be liable for labor charges in excess of three strips.
IMPORTANT Ð READ BEFORE PROCEEDING!
Film-faced wallcovering can act as a vapor barrier and consequently should NOT be installed on walls that are susceptible to excessive condensation or moisture infiltration. This may be more likely to occur in Humid and Fringe Zone 1 climates.
To reduce the risk of fungal growth within the wall or wall cavity we strongly recommend the use of microvented, permeable wallcovering. The following conditions should be observed:
Permeable wallcovering cannot compensate for water intrusion caused by poor building envelope design, faulty construction, building system failure or improper maintenance practices.
All surfaces must be clean, dry smooth and structurally sound. Sand-finish plaster must be scraped smooth. Cinder or cement blocks must be plastered or cemented smooth before application of the wallcovering. Newly plastered walls must be completely dry before application Ð check walls with a reliable "moisture meter" to make sure they are dry to the satisfaction of the architect. Proper surface preparation is the key to getting great results. To prepare the surface properly, we recommend that you prime all surfaces with Shieldz VP, Gardz, or Bullseye 123 acrylic wallcovering primer by Zinsser. The wallcovering will be easier to hang and easier to remove at redecorating time. Any mildew MUST be removed from the walls and surfaces treated to inhibit further growth. If mold and mildew are a potential concern, use Shieldz Universal "Plus" by Zinsser.
Use Zinsser SureGrip #134. APPLY ONLY AT FULL STRENGTH Ð Whip or Stir DO NOT DILUTE! Apply a liberal even coat of adhesive over the entire back of the wallcovering by either running strips through a pasting machine or with a 1/2" nap application roller. "Book" material for 15 minutes. For additional adhesive assistance or sourcing call Zinsser at 1- 888-855-1774. TIP: Undiluted adhesive with proper booking time will help ensure a successful installation.
Use Zinsser SureGrip #134. APPLY ONLY AT FULL STRENGTH Ð Whip or Stir DO NOT DILUTE! Apply an even liberal coat of adhesive using" nap application roller to no more than 3 drop sections of the wall. If performing a double cut, push-pin back loose top corner to avoid having the material fall. At the point of double cut you will need to open seam area, reapply a light coat of adhesive in the seam area, (wet Velcro technique), to avoid seaming issues. Lightly work seam back together and follow the remainder of these instructions. For additional adhesive assistance or sourcing call Zinsser at 1- 888-855-1774.
Use rolls in sequential order starting from the highest number working down to the lowest number. Number strips and headers as they are cut from the roll. Apply to the wall in the exact order as they were cut. Fill in over and around doors and windows as you come to them with strips cut in consecutive order from the roll. Allow ample material for matching of repeats (if applicable) and trimming at the ceiling and floor line. Make certain that run or dye-lot numbers are broken only at a corner.
Do not use a steel broad-knife for smoothing wallcovering or seams. Enviro-Wall Cover® is softer than steel blades and damage to wallcovering surface will occur. To avoid burnishing the face of the material, use either a sweep brush or soft poly smoothing tool. Do not install wallcovering unless a temperature above 55° F is maintained in both areas of installation and storage for at least 48 hours prior to installation. IT IS MOST IMPORTANT THAT PERMANENT LIGHTING BE IN EXISTENCE PRIOR TO AND DURING INSTALLATION OF ALL WALLCOVERING. DO NOT INSTALL WITH TEMPORARY "PIGTAIL" LIGHTING. Before installing, EXAMINE PATTERN FOR COLOR and establish if there is any REPEAT TO THE DESIGN. Determine whether the pattern match is random, straight across or half drop and add material to the length accordingly. When installing a textured or non-matched pattern, reverse hang alternate strips to ensure color consistency.
