Installing SanFoot® Natural Wood Veneer Wallcovering
Please read these instructions completely before proceeding with the installation. If you have any questions regarding the installation procedures contained herein, contact your local SanFoot Natural Wood Veneer Wallcovering Distributor or call Jacaranda, Inc. at 800-225-6384 or 305-624-0003.
The installation process is critical to the aesthetic appeal and acceptance of SanFoot. Surface preparation, adhesive and primer selection, environmental condition and quality workmanship are the key elements for a successful installation. SanFoot comes from the factory prefinished with urethane sealer and finish.
Inspection of Product:
Please inspect for damage before signing acceptance of product. If damage is noted, please advise freight carrier immediately when signing for the product from the freight carrier. Examine all sheets of SanFoot Natural Wood Veneer Wallcovering upon receipt for quality and compliance with the approved specification before storing or starting installation. Any shortage of material must be reported within three (3) days after receipt of material.
The installing contractor must verify that the correct specified species of wallcovering is present on the job site. Furthermore, the installer must also review the hanging instructions that accompany each wallcovering. If there is failure to follow the specifier's supplied wall finish schedule and material design boards, Jacaranda, Inc., Zinsser Co., and our distributors assume NO responsibility for any incorrect hanging locations, incorrect wallcovering species numbers and species grains that are hung in the wrong direction.
Storage:
SanFoot should be kept in the manufacturer's packaging until 24 to 48 hours before installation. Store in a clean, dry, secure area that has low humidity and a stable temperature range of 45 to 85 degrees Fahrenheit.
Environmental Conditions:
Areas to receive SanFoot should be environmentally controlled by the permanent HVAC system. Maintain a temperature range of 65 to 85 degrees Fahrenheit, with not more than 50% relative humidity and not less than what is specified for your area in the AWI Quality Standards Section 1700-T-19, for a period of not less than four (4) days prior to installation and maintained thereafter.
Preparation of SanFoot Natural Wood Veneer Wallcovering:
Remove SanFoot sheets from the box and allow the sheets to relax and acclimate to the environment for approximately 24 to 48 hours. If the air is dry, or if the sheets must remain out of the box for an extended period of time, cover with a sheet of vinyl to prevent the veneer from drying out. It is best to lay the sheets face down during this period, and not directly on the floor.
After preliminary inspection, arrange SanFoot sheets in numerical sequence as labeled on the back of each. Along with the sequence number, each sheet also has a flitch number and the word "bottom" printed on the back. All sheets should be installed in sequence order and in the same direction with all "bottoms" down or all "bottoms" up based on appearance preferance. In most cases, the installation should start at the top left descending left to right, on 9' or 10' walls. When wall is taller than one (1) sheet of material, installation should start at top left descending top to bottom then left to right.
Primer:
Prime all surfaces (including oil-based paint, oil-based primers and latex or oil-based stain-kill coatings) with specified primer by Zinsser Co., Inc. Prime all surfaces according to manufacturer's directions. For best results, apply primer with a roller and let cure at least two (2) days before installing SanFoot Natural Wood Veneer Wallcovering. Call Zinsser Co., Inc. for application questions and technical information related to recommended Zinsser primers - toll-free at 1-888-855-1774, or review technical data bulletins online at www.zinsser.com. Consult your SanFoot Distributor, or contact Jacaranda, Inc. for the SanFoot Distributor in your area before proceeding with any unusual conditions.
The use of the primer will prevent the adhesive from being excessively absorbed into the drywall and stop dry pockets plus a primer promotes strippability to SanFoot material. Primers like Bulls Eye 1-2-3 or Shieldz VP allow moisture in the adhesives to wick away from the SanFoot material. Moisture content in the wall substrate should be in a range of 7% to 9% or less. Check with a moisture meter if necessary.
If a situation is encountered where the walls were previously painted or primed, the surface should be lightly sanded to break the seal prior to applying Zinsser Primer, preferably Bulls Eye 1-2-3. One test strip of SanFoot should be hung to assure a strong bond between the existing paint/primer and the Zinsser primer before proceeding with the installation. Any failure caused by the existing painted/primed surface is the responsibility of the installing contractor and not of Jacaranda, Inc. or Zinsser Co., Inc.
The following Zinsser Co. acrylic primers are approved for use with SanFoot:
Bulls Eye 1-2-3 Primer Sealer
(Recommended over wood composite board) - Over painted surfaces or where primer needs to be tinted.
Shieldz Universal PLUS Primer
Over new or clean drywall or where mold and mildew is a concern.
Gardz High Performance Sealer
Use over damage drywall, loose paint or chalky surfaces.
Do not use alkyd/oil base primers with SanFoot Natural Wood Veneer Wallcovering.
Use one of the following approved adhesives, Mfr. Zinsser Co. Inc.:
SureGrip 134 Clay Strippable Wallcovering Adhesive (allow to book for 15 minutes)
SureGrip 138 Heavy Duty Clay Wallcovering Adhesive (allow to book for 10 minutes)
Jacaranda, Inc. does not recommend the use of clear or clear strippable type adhesives.
Use one of the approved adhesives manufactured by Zinsser Co., Inc. Prepare wall surface as specified before beginning and use ONLY specified adhesive(s). APPLY ADHESIVE AT FULL STRENGTH - whip or stir to thin to desired consistency. DO NOT DILUTE ADHESIVE WITH WATER!! Apply a uniform layer of adhesive to the back of the SanFoot sheets with standard 3/8 to 3/4 inch nap paint roller, making sure there are no uncoated areas, book the sheets for 10 to 15 minutes before hanging. Allow the proper time for adhesive to tack after it has been applied to the back of the sheets. This is important to prevent bubbling after installation. Depending on the condition of the primed substrate, the installer may choose to size the wall surface with a thin coating of the specified adhesive and allow it to tack prior to hanging. It is suggested that the installer test an area first to determine if an adhesive size is needed.
Installing SanFoot Natural Wood Wallcovering:
Apply the sheets to the wall in sequence, filling in over doors and windows from consecutive sheets. After applying each sheet on the wall, smooth with an acrylic smoothing tool, or with smoothing tools which will not mar the finish, but ensure that all air bubbles are eliminated and there is a good bond between the SanFoot and the substrate. Smooth entire surface area of the sheet to ensure all air pockets are eliminated. Air bubbles must be removed, and installation errors corrected, before the adhesive dries. Remove excess adhesive from each sheet as you go along prior to installing the next sheet. Use a clean, moist, natural sponge to remove excess adhesive and dry surface with a lint free towel. It is very important to change water frequently in order to maintain cleanliness and not streak the appearance. DO NOT install SanFoot with temporary lighting. Installation with permanent lighting is recommended. Sufficient lighting will greatly enable to see air pockets or bubbles and other installation problems that may occur.
Factory trimmed edges can be butt jointed during installation, but for best results with seams, it is suggested to overlap and double cut all seams with a razor blade. For installation of SanFoot sheets that are ten feet (10') and longer, Jacaranda requires all joint seams to be double cut in order to achieve a tight acceptable joint seam. Vertical joints should not occur less than two and one-half inches (2-1/2”) from all outside and inside corners if at all possible, based on the corner being in square. Leaving SanFoot overlapped at the seams is not acceptable.
The following holds true on all corners that are square. Wrapping an outside corner with SanFoot is done in the same manner as heavy-duty vinyl wallcovering with one exception. When bending around an outside corner, wet the face of the prefinished SanFoot with clean water and a clean lint-free rag. The moisture added will allow the wood to bend around the corner without breaking. Follow these same steps for an inside corner as well. Note: If the corner is not straight and true, please contact your SanFoot distributor or Jacaranda for additional instructions.
Air bubbles must be removed and installation errors must be corrected before adhesive dries. Sufficient lighting will greatly assist in seeing bubbles and other installation problems. After installing three (3) sheets of SanFoot Natural Wood Veneer Wallcovering, inspect the material for proper installation. If problems occur, STOP and contact the local SanFoot Distributor. Proceeding beyond this point will be done at the installer's risk and will absolve Jacaranda, Inc., the local SanFoot Distributor and Zinsser Co., Inc. of all responsibility.
Test Area Approval:
At no additional cost to the owner, the Wallcovering Installation Contractor shall install not less than three (3) full-width sheets of each pattern specified, in an area designated by the Architect, Designer or Owner. The test installation area shall be reviewed for conformance to the manufacturer's standard installation instructions and recommended adhesives. Only the Architect, Designer or Owner shall approve the test installation. The Contractor shall replace any unsatisfactory sheets as directed by, and until the test area is accepted by the Architect, Designer or Owner.
Use of an unspecified adhesive, primer or any additional finishes will VOID the manufacturer's warranty at time of installation. Future problems that may occur as a result of incorrect installation procedures are not the responsibility of Jacaranda, Inc., Zinsser Co., Inc., or any of their distributors.
The approved test area shall remain as part of the finished installation work and as a standard of comparison for the installation throughout the project. The Contractor shall not install specified material beyond the test area prior to the approval of the test area, by the Architect, Designer or Owner. Proceeding beyond this point will be done at the installer's risk and will absolve Jacaranda, Inc. the local SanFoot Distributor and Zinsser Co. Inc. of all responsibility.
All drywall finishing should comply with Association of Wall and Ceiling Industries-International (AWCI), Painting and Decorating Contractors of America (PDCA) specifications, Level 4 or Level 5 as a guide. By incorporating the appropriate Level of Finish of the recommended specification into the project documents, the architect, general contractor, and building owner can better anticipate the final appearance of the decorative wall or ceilings covered with SanFoot Natural Wood Veneer Wallcovering. “All joints and interior angles shall have tape embedded in joint compound and three separate coats of joint compound applied over all joints, angles, fastener heads, and accessories.” All surfaces shall be clean, smooth and dry prior to applying primer and the application of SanFoot.
Painted Drywall:
Surfaces painted with alkyd/oil paint will not allow the moisture to be absorbed into the drywall. Therefore, a wall liner must be applied before proceeding with hanging SanFoot Natural Wood Veneer Wallcovering. Allow sufficient time for the moisture in the adhesive used to install the wall-liner to evaporate and cure. Contact your SanFoot distributor or Jacaranda for reccommendations for wall liners. A paper wall liner is all that is needed in this application.
Acrylic/Latex Surface -
Sand painted surface to break the seal. All painted surfaces must be primed with Bulls Eye 1-2-3 by Zinsser Co., Inc. to ensure strong bond of SanFoot. Allow freshly painted drywall to cure at least 14 days prior to priming and installing SanFoot.
Damaged Drywall:
Prime damaged areas such as torn drywall facing paper, over skim coat repairs and old adhesive residue with Gardz High Performance Sealer.
Plaster Walls:
New Plaster (1/2 “ to _” thickness) - Ideally new plaster walls should age 60 to 90 days before painting or installing SanFoot. If you cannot wait, then wash newly plastered walls with zinc sulfate solution to neutralize the lime (2-4 pounds of zinc sulfate crystals per gallon of water). If new plaster surface is chalky, prime with Gardz High Performance Sealer by Zinsser Co., Inc.
Painted Plaster:
All efflorescence crystals should be removed before starting the installation. All undulations in the plaster must be smoothed to a flat finish. Installation over previously painted plaster surfaces must be installed with attention to the type of paint applied to the surface and the number of coats it has received over time.
If the painted surface can not be broken by sanding then a wall liner must be installed before applying SanFoot over painted plaster to allow the moisture to be wicked away.
Concrete, Ceramic Tile, Marble or other Un-level and Irregular Surfaces:
Contact your SanFoot distributor or Jacaranda for more information.
All surfaces should be free of all excess dust, oils or other foreign matter and be maintained as smooth as possible. All seam joints should be mudded and sanded to fill all gaps for a smooth surface. All surface areas will need to be primed with Bulls Eye 1-2-3 Primer Sealer from the Zinsser Co., Inc. before starting the installation of SanFoot. Keep in mind that your substrate will not allow a lot of moisture to be absorbed; therefore, you will use a little less adhesive in this application than over drywall.
Contact Adhesive over Non-Porous Surfaces:
Substrates that may require the use of contact adhesive are: painted metal, stainless steel, plastic laminate and other non-porous surfaces. Never use contact adhesive on drywall or plaster.
1. Preparation: Always be sure that both surfaces are clean and free of all dust. The SanFoot material and the substrate of choice should be stored in the same surroundings for 24 to 48 hours before starting the installation. This will allow both products to acclimatize together before bonding.
2. Adhesive: When using a contact adhesive, always use 100% coverage on both the back of the veneer sheet and the face of the substrate. Let the adhesive have the correct amount of dry open time. You don't want to trap gases that can later cause blisters. The time can vary depending on the airflow around your work area, ambient temperature and humidity at the time of installation. Follow all instructions on the label of the contact adhesive being used.
3. Bonding: When contact adhesive is being used the best method of pressure is a lot of pressure all at one time. This pressure can be reached by using an acrylic smoothing tool covered with a felt cloth when using prefinished SanFoot sheets. (Do not use a J-Roller for applying pressure.) Starting in the center of the surface to be bonded, pull the smoother toward you going with the grain. Apply pressure with both hands, pushing down as hard as possible. Keep doing this as you move over 3- 4 inches at a time (your smoother should be 4 to 5 inches wide) until you have rubbed down the entire surface.
DO NOT USE A J-ROLLER TO APPLY SHEET VENEER WITH CONTACT ADHESIVE
4. Time: Don't rush your work. In order for contact cement to work, a chemical reaction must take place. This reaction produces gas and you need to allow this gas to escape from the edges. Many jobs appear perfect and then blisters start to appear. Reasons for this may include: 1) Insufficient adhesive coverage; 2) Not enough pressure was applied to form an intimate bond; 3) Insufficient amount of open time.
Changing the Color / Finish:
A quality brand of finish should be used to assure a good, pleasing, finished look. A water-based, self-leveling urethane with color-tint can be added to darken the wood species or urethane with a different sheen level can be added. Please keep in mind that if any chemical product is added over the finish coat of SanFoot Natural Wood Wallcovering, the Class “A” Fire Rating may change. Please check with your local fire
Manufacturer's instruction should be followed in applying all products with the exception of one factor, cleaning and sanding of veneer face. The sanding should be done with 3-M Trimite sand paper 380 grit or a Scotch-Brite pad, medium/fine grade (gray color). Sand the complete wood face area, clean off all powder residues with a clean lint free cloth. Option to sanding is to clean the face of SanFoot with de-natured alcohol for a chemical bond.
Please remember when doing the additional finishing process: Wood moves anytime moisture is added or removed. Therefore, always add all chemicals in stages to help eliminate the chance of bubbles; do not flood the wood face at any time for this will increase your chance for bubbles and blisters.
