Installing Mori Wood Veneers Wallcovering
New Drywall
All drywall finishing should comply with the Association of Wall and Ceiling Industries- International (AWCI), Painting and Decorating Contractors of America (PDCA) specifications, Level 4 or Level 5 as a guide. All surfaces shall be clean, smooth, and dry before applying primer and the application of Mori Wood Veneers™.
Existing Drywall: (Contact Manufacturer)
Surfaces painted with alkyd/oil paint will not allow the moisture to be absorbed into the drywall. Sand and Float wall to break seal. Apply a paper Wall-liner before proceeding with hanging Mori Wood Veneers™. Conduct a test strip before proceeding with the complete job.
Acrylic/Latex Surface (Contact Manufacturer)
Sand painted surfaces to break the seal. All painted surfaces must be primed with PRO-999 (R35) by Roman Decorating Products to ensure strong bond of Mori Wood Veneers™. Allow freshly painted drywall to cure at least 14 days prior to priming and installing Mori Wood Veneers™.
Plaster Walls (Contact Manufacturer)
New plaster (1/2” to 3/4” thickness) – Ideally new plaster walls should age 60 to 90 days before painting or installing Mori Wood Veneers™. If you cannot wait, then wash the newly plastered neutralize the lime (2-4 pounds of zinc sulfate crystals per gallon of water). If the new plaster surface is chalky, prime with PRO- 977 by Roman Decorating Products.
MDF, Particleboard, other Wood Composites, or Hardwood Plywood
All surfaces should be completely free of excess dust, oils, or other foreign matter and maintained as smooth as possible. Prime all surface areas with Pro-935 by Roman Decorating Products before starting the installation of Mori Wood Veneers™.
Non-Porous Surfaces (Contact Manufacturer)
Painted metal, stainless steel, plastic laminate and other non-porous surfaces will require the use of a contact adhesive.
Environmental Conditions:
Areas to receive Mori Wood Veneers™ should be environmentally controlled by the permanent HVAC system for at least four (4) days. Maintain a temperature range of 65 to 85 degrees Fahrenheit, with not more than 50% relative humidity.
Please read these instructions completely before proceeding with the installation. If you have any questions or concerns regarding the installation procedures contained herein, contact your Mori Wood Veneers™ representative.
The installation process is critical: Surface preparation, adhesive and primer selection, environmental condition, and quality workmanship are crucial elements for a successful installation. Only professional installers should install Mori Wood Veneers™.
Product Inspection:
Inspect prior to receipt of product from shipper. Notify Carrier if sign of damage. Examine all sheets of Mori Wood Veneers™ upon receipt for quality and compliance with the approved specification before storing or starting installations. Any shortage of material must be reported within 3 days from receipt of material.
The installing contractor must verify that the correct specified species of wall covering is present on the worksite. The installer must also review the installation instructions that accompany each order of Mori Wood Veneers™. Mori Wood Veneers™ assumes no responsibility for any incorrect installation procedures.
Storage:
Mori Wood Veneers™ should be kept in the packaging until 24- 48 hours before installation. Store in a clean, dry, secure are that has low humidity and a stable temperature range of 45 to 85 degrees Fahrenheit.
Preparation:
Remove Mori Wood Veneers™ sheets from the box and allow the sheets to relax and acclimate to the environment for approximately 24 to 48 hours. Arrange Mori Wood Veneers™ sheets in numerical sequence as labeled on the back of each sheet. In most cases the installation should start at the top left descending left to right.
Primers/Sealers:
Prime all surfaces (including oil-based primers and latex or oil based stain-kill coatings) with specified primers listed below. Prime all surfaces according to the manufacturerʼs directions. Let primer cure at least 2 days before installing Mori Wood Veneers™. The use of the primer will ensure good contact with Mori Wood Veneers™. The sealers will prevent the adhesive from being excessively absorbed into the drywall. It will also enhance strip ability. Moisture content in the wall substrate should be in the range of 7% to 9% or less. Check with a moisture meter if necessary. Three (3) test strips of Mori Wood Veneers™ should be hung to assure a strong bond between the existing primer/sealer and the primer before proceeding with the installation.
The following primers are recommended for use with Mori Wood Veneers™:
- PRO-999 (RX-35) by Roman Decorating Products – For use over new or clean drywall
- Shieldz Universal WHITE Wallcovering Primer by Zinsser.
DO NOT USE ALKYD/OIL BASE PRIMERS WITH MORI WOOD VENEERS
Adhesives:
Use one of the following approved clay-based adhesives with Mori Wood Veneers™:
Dynamite 111 Heavy Duty Clay by Gardner-Gibson
DO NOT USE CLEAR OR CLEAR STRIPPABLE ADHESIVES
Application of Adhesives
Use one of the approved adhesives, or adhesives preferred by a professional installer. Before installation prepare the wall surface as specified and use ONLY specified adhesive(s).
APPLY ADHESIVE AT FULL STRENGTH ‒ DO NOT DILUTE ADHESIVE WITH WATER!!
1. Use a clean damp sponge of water and apply evenly to the back of the Mori Wood Veneers™ sheet (Water activates the backing for proper tack) making sure all areas of sheet are damp. Do Not over wet backing of sheets.
2. Apply an even coat of adhesive on wall with a half (1/2) inch paint roller cover nap. For corners and edges, use a latex painters brush. Do not over saturate adhesive. Ensure all areas are applied evenly before installation.
Installing Mori Wood Veneers™ Wallcovering
Hang the sheet on the wall, smooth with an acrylic smoothing tool, or with tools that will not scratch the finish. Air bubbles must be removed from the center to the edge. Ensure that all air bubbles are eliminated and there is good smooth adhesion between Mori Wood Veneers™ and the substrate. Remove excess adhesive from each sheet after adhesive dries. Use a clean, moist, natural sponge to remove excess adhesive and dry the surface with a lint-free towel. It is very important to change water frequently to maintain cleanliness and not to streak the appearance.
Seams:
It is recommended to overlap at least 3/4″ inch and double-cut all seams with a clean sharp razor blade. Change the blade after each cut. For installation of Mori Wood Veneers™ sheets ten (10ʼ) and longer, Mori Wood Veneers™ recommends all joint seams to be double cut to achieve a tight acceptable joint seam. Vertical joints should not occur less than 6” inches from all outside and inside corners if possible. The installer is fully responsible for proper seam fitting.
Post-installation inspection:
After 72 hours, re-inspect the installation for quality assurance.
Test Area for Approval
Only the Architect, Designer, or owner shall approve the test installation.
