Preparation of Goods: Examine goods to assure that pattern, color, quantity, and quality is as ordered. Separate goods by shade lot number and organize in roll number sequence, starting with the highest.

Preparation of Substrate: MarkaWall can be installed over almost any properly prepared impervious surface, such as high pressure laminates and steel.
MarkaWall adhesive-backed material is not recommended for use over drywall or similar surfaces; for installations such as these, use a MarkaWall non-woven or scrim backed product. Surfaces to be covered must be clean, smooth, dry, uniform in color, and structurally sound.
Loose paint or other wallcovering must be removed. Nicks, gouges, and other surface imperfections should be filled, sanded smooth, and sealed.

Do not hang over ballpoint pen ink, wax crayon, ink marker, oil-based stains, or any foreign matter that may bleed through.
It is suggested that pencil be used to mark vinyl or wall as pencil marks do not bleed.

Remove any substrate mildew with a chlorine bleach solution, rinse, and allow to dry before installing. Wash greasy surfaces with an ammonia solution, rinse, and allow to dry before installing.

Some fillers contrast with the color of the substrate, showing strong light and dark colored areas. MarkaWall wallcovering may allow show-through due to the limited amount of opacity. Should this situation occur, it is recommended to use a high quality acrylic primer over the patched area, tint primer to match the substrate color.

For installation over steel, an application of a rust inhibitive primer to the substrate should be used. The rust inhibitive primer will lessen the likelihood of degradation to the metal surface. For applications over electro-galvanized, paint-lock, or galvaneeled steel no primer is required.

Application of Wallcovering: When installing vertically use a plumb line. When installing horizontally use a level line. Horizontal installation is recommended. Although seams can be written over, it is suggested to keep them out of the primary writing and viewing areas, (30-85 inches from the floor for 60 material and 30-76 inches for 48-50 material). Be sure to reverse every other strip regardless of vertical or horizontal installation method.

Cut strips a few inches longer than required to allow for trimming at sidewall, ceilings, and baseboards.

To remove air pockets, water pockets, and double cut waste, pre-wet the substrate with a soapy solution, consisting of 1/2 capful of mild detergent (such as dishwashing liquid), to 2 gal. clean water. Use a natural sponge or a lint free towel to dampen the substrate. If seams are necessary, apply a more liberal amount of the soapy solution to that area.

For larger runs, two installers are recommended. Pull at least one foot of the backing away from the material prior to making contact with the substrate. One installer aligns the material to the plumb or level line and then use a flex wallcovering smoother (wrapped with a soft clean cloth) to remove air and water pockets. Use a downward and outward motion, assuring complete adhesion to the wall. The other installer will pull backing away from the vinyl slowly and evenly as the top installer works closer. NOTE: At seams, leave the solution under the material to allow for double cutting. Also, dampen the surface edge of the installed sheet approximately 2-4 inches in from the seam with the solution. This will allow the waste material from the double cut to be removed. Using a straight edge, double cut the seam. Remove the off-cut pieces, then remove all the excess solution.

Lightly roll or press the seams down. Trim material at the ceiling, baseboard, windows, and doors with a single edged razor blade (change razor blades often).

1) Vertical joints should not occur less than 6 from the outside and inside corners.

2) Do not stretch the material to butt seams-slide the entire strip for proper fitting. Do not use metal or sharp objects on the surface when installing materials.

3) Be careful not to crease or bend material when handling.

4) Do not puncture air bubbles under the surface.

5) If the strip goes up unevenly, peel it off and reinstall.

6) Professional installation is recommended.

Extreme care should be exercised when trimming wallcovering around electrical outlets. Cut clear around all electrical openings so adequate clearance is allowed between material and electrical wiring and boxes. Turn off electricity when working around electrical outlets.

Clean up: Rinse thoroughly with clean water and dry with clean toweling. Do not use abrasive cleaners.

Notes: BE sure you have done a thorough job getting out moisture and air bubbles.  Get a spot light and look at the board with your face near the board looking down the length.  If you just look at board from a couple of feet away in standard light you will miss small bubbles which will grow overnight into an unacceptable mess.   Also any type of surface that may have moisture in it should be thoroughly sealed or the moisture can cause bubbles.

Important: If you have any questions about the material, stop working and notify your supplier. We are not responsible for the appearance and performance of wallcovering not applied according to these instructions. If, after applying three strips, there is some question of appearance, contact your supplier.           03/01
