Preparation of Wall Surfaces: Proper wall prep requires that all wall surfaces to be installed must be clean, smooth, dry, uniform in color, structurally sound and free of mold, mildew, grease or stains. To ensure good adhesion, any old wallcovering and/or loose paint flakes must be removed. To ensure a smooth wall surface, imperfections, such as nail heads and gouges, should be filled with joint compound, allowed to dry and then sanded smooth. If the wall surface has any grease stain, wash with a solution of diluted ammonia, rinse and allow to dry. Remove any pen, ink, wax crayon, or other stains, if needed, apply a stain-blocking latex primer/sealer to prevent shadowing. For new drywall, use medium grit sandpaper and then 120-grit sandpaper to achieve a Level 5 finish for optimal results.
Roman ECO-988 primer must be applied prior to installation of dry erase wallcovering.
Moisture Accumulation: Some buildings, particularly in warm, humid climates, can have moisture infiltration problems which can lead to mold and mildew growth. Any such problem must be corrected prior to the installation of wall covering. This product is only intended for use in building that are properly designed and maintained to avoid moisture infiltration and/or condensation within the wall cavities. If any mold/mildew is present or if the walls show signs of visible moisture damage, do not proceed with the installation until the condition has been fully corrected under the direction of a qualified expert. For proper installation and product performance, walls to be installed should be checked with a reliable moisture meter. Moisture content shall not exceed 4%.
Application: When installing vertical strips, use a plumb line to ensure accuracy. For horizontal installations, use a level line to maintain proper alignment. For horizontal applications, carefully plan the placement of seams to ensure uniformity. Measure the wall and establish the location of the first strip, typically positioned 30 inches from the floor and spanning an average length of 20 feet. Ensure that vertical joints are not positioned within 8 inches of inside or outside corners.
It is recommended to only use lead pencils to mark the back of wallcovering or wall surfaces.
Before cutting the material, make certain the color and gloss level are satisfactory as specified. Arrange rolls in number sequence starting with the highest. Cut strips 2–3” longer on both ends to allow for trimming at sidewalls, ceilings, and baseboards.
Apply a uniform coat of adhesive (Roman ECO-788 clay strippable adhesive) to the wall using a low nap roller, allow it to tack up for 15 minutes (adjust based on room humidity), and re-paste the entire wall. Smooth out the adhesive thoroughly to eliminate lumps before applying the wall covering.
For a full wall application, begin by installing the center panel at full width. Next, install the second panel, aligning its factory edge with the ceiling. Finally, install the third panel, ensuring it lines up with the previous two and is adjusted to the desired height.
Carefully unroll the dry erase wallcovering over the pasted wall, ensuring proper alignment. Use a laser level to maintain straightness throughout the installation process. Allow a 2-inch overlap at the edges to facilitate clean double cutting.
Wet the dry erase surface with a cellulose sponge. Using a wide, flexible squeegee wrapped in a clean, soft cloth, gently smooth the material from the center outward toward the upper and lower edges. Make sure there are no air bubbles or excess paste pockets left behind.
When double cutting overlapping sections, be careful not to score the drywall or substrate beneath. To prevent indentations, use smoothing tools gently.
Trim the edges and outlets with a fresh single-blade cutter and a metal guide. Dry the surface completely to avoid ghosting, and remove any excess water promptly. Use a seam roller to ensure the seams are securely bonded.
Within 45 minutes of hanging each piece, inspect the seams and lightly re-smooth as necessary. Avoid excessive pressure to prevent indentations.
