IMPORTANT - READ BEFORE PROCEEDING!

Moisture, Mold and Permeability

Vinyl wallcovering acts as a vapor barrier and should NOT be installed on walls that are susceptible to excessive condensation or moisture infiltration. To reduce the risk of fungal growth, it is recommended that all wallcovering be micro-vented when installed in Humid and Fringe Zone 1 climates.

We strongly recommend the use of micro-vented, permeable wallcovering to reduce the risk of fungal growth within the wall or wall cavity, the following conditions should be observed: 

  • The building’s exterior envelope must be weather0tight and the HVAC system must be operating before, during, and after installation
  • The wall surface to be covered must be completely dry and free of any indications of prior mold/mildew growth before installation.
  • The wallcovering supplied by Len-Tex may be made permeable (minimum 8+ perms) by an optional micro-venting process

1)  CONFRIM THE PRODUCT

  • Before cutting this material, you must confirm the accuracy of the pattern, color, and yardage; no returns will be allowed for the cut material.
  • You may confirm the wallcovering is micro-vented by holding it in front of bright light so the penetrations are visible.

2)  PREPARE THE WALLCOVERING

  • Confirm that consecutive bold (roll) numbers are being used and lot numbers are identical.
  • If transported during the winter months, the wallcovering must be allowed to warm to normal room temperature.
  • Recommended wall preparation )below) and ease of installation is best accomplished when the building temperature is 70 degrees before beginning work.

3)  PREPARE THE WALL SURFACE

Proper surface preparation is the key to getting great results! To prepare the surface properly, we recommend priming all surfaces with Roman Decorating ULTRA PLUS ECO-988 (for micro-vented wallcovering and NSF/ANSI 342 compliance) or PRO-977. The wallcovering will be easier to hang and easier to remove at redecorating time.

  • All surfaces must be clean, dry, smooth, and structurally sound.
  • Existing wallcovering must be removed from the surface before installation.
  • Sand-finish plaster must be scraped smooth.
  • Concrete block walls must be skim-coated smooth before application of the wallcovering.
  • Newly plastered walls must be completely dry before application. Verify by using a “moisture detector” and make sure the walls are dry to the satisfaction of the architect. 
  • Any mold or mildew MUST be removed from the walls and must be treated to inhibit further growth. Refer to the EPA website for guidelines on cleaning and removing mold: www.EPA.gov. These standards must be followed!

4)  ADHESIVE APPLICATION - WET HANG

  • Use Roman ECO-788 clay-based adhesive (for micro-vented wallcovering and NSF/ANSI 342 compliance) or PRO-774.
  • Follow the manufacturer’s instructions for diluting the adhesive with water.
  • Apply a liberal, even coating of adhesive over the entire back of the wallcovering by using a pasting machine or by using a 112" nap application roller.
  • "Book" material for 15 minutes

BEST PRACTICE: Adequate booking time will help ensure a successful installation.*

5)  ADHESIVE APPLICATION- DRY HANG

  • Use Roman ECO-788 (for micro-vented wallcovering and NSF/ANSI 342 compliance) or PRO-774. ROLL ONLY FULL-STRENGTH ADHESIVER ON THE WALL - DO NOT DILUTE!
  • Apply an even liberal coat of the adhesive using a 112" 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 the seam area, and reapply a light coat of adhesive in the seam area, (AKA: the velcro technique), to avoid seaming issues.
  • Lightly work the seam back together and follow the remainder of these instructions.
  • For assistance with sourcing and/or using primers and adhesives, as well as technical questions, contact Roman Decorating Products at 1-800-488-6117

BEST PRACTICE: Difficult installations, such as columns or outside corners, particularly with Type II wallcoverings, may be facilitated by applying adhesive to both the wall and the wallcovering, and allowing both surfaces to "tack up" (the velcro technique). This will increase the wet tack of the adhesive to wrap corners or columns.*

6)  INSTALL THE WALLCOVERING

BEFORE INSTALLING, EXAMINE PATTERN FOR COLOR AND REPEAT IN DESIGN. Some patterns should be lined up, matched, and/or alternately reversed depending on color and texture to ensure color uniformity.

NOTE: This wallcovering must be installed in the reverse roll number sequence.

  • Hang the first strip even with the plumb line
  • Use strips in exact order as they are cut from the roll
  • Fill over and around doors and windows as you come to them with strips cut in consecuitve order from the roll.

CUT AND INSTALL THREE (3) STRIPS ONLY!

  • Then, inspect for color shading or pattern variation. If the appearance is not acceptable, stop hanging and contact your supplier.

THE MANUFACTURER WILL NOT BE LIABLE FOR MATERIALS OR LABOR CHARGES FROM INSTALLING MORE THAN THREE (3) STRIPS OF WALLCOVERING.

IT IS MOST IMPORTANT THAT PERMANENT LIGHTING BE IN EXISTENCE BEFORE AND DURING THE INSTALLATION OF ALL WALLCOVERING. DO NOT INSTALL WITH TEMPORARY "PIGTAIL" LIGHTING.

7)  SEAMING

It may be done in one of the following two methods:

  • The first and advised method is to overlap strips on the wall and cut through the overlap taking care not to score the drywall. Overlap the strips about 2 inches and using a straight edge and appropriate double cutter, cut down the middle of the double-lapped thickness, using a fresh blade for each double cut. Remove the top and bottom strips and work into a tight seam using a seam roller, or a polyethylene or PVC smoothing blade.
  • The second method is to butt the material. This holds the cleaning to a minimum which is especially important when working with deep textures and dark colors. The best butt seams require pre-trimming with a straight edge on a cutting table.

NOTE: Do not use steel blade knives for smoothing wallcovering or seams. Vinyl wallcovering is softer than steel blades and damage to wallcovering surface will occur.

  • As each strip is installed, carefully wash excess adhesive from the seams. Use a sponge dampened with clean, warm water, which has been changed frequently, and dried witha clean soft towel. Adhesive residue will discolor seams or leave a dull vertical area.

Adhesives not cleaned promptly from the surface of the wallcovering will be difficult to remove after it has dried - Piranha, DIF, or similar products may help if this occurs.

Taping seams with 2" masking tape before lapping and cutting will eliminate any potential problems with adhesive residue. Always carry wallcovering around corners approximately 6" making no outside corner cut. If a corner-cutting is unavoidable, do not overlap and cut - butt each strip separately resulting in a tight corner seam. Trim excess material from base moldings, door, and window frames with a sutiable razor knife and cutting guide.
