Sisal wallcovering is woven 100% of natural sisal fiber. This fiber is extracted from leaves of the henequen and sisalana agave plant, which is grown for its annual harvest of fiber. Once the plant reaches maximum maturity and stop producing after 10 to12 years, new replacement plants grow to early maturity in 3 to 4 years. |

Testing: Professional Testing Laboratory Inc., Dalton GA
Test Result: No evidence of exceeding industry guidelines for; total VOC level tolerances, 4 PC (phenelcyclohexene) level, formaldehyde level, styrene level.

Test 1
Passes Full Scale Room Corner Test as established by NFPA (National Fire Protection Association) Life Safety Code. Carpet and carpet-like wall coverings (textiles, woven, nonwoven, napped, tufted, looped, or similar surface)
for use in areas without automatic fire sprinklers.
Test meets requirement of National Building Codes: UBC 8-2 , BOCA 803.6 , IBC 803.5, SBCC
Testing: Southwest Research Institute, Department of Fire Technology, San Antonio Texas
Test Procedure:Wallcovering may be judged to perform satisfactorily when tested according to the fully-lined test
procedure and meeting the following criteria: (1) Flames shall not spread to the ceiling during the 40-kw exposure
(2) During the 150-kW exposure; flames shall not spread to the outer extremity of the sample on the 8 x 12-ft walls.
Flashover shall not occur. Flashover shall be judged to have occured when the heat flux at floor level exceeds 20
kW/m2, average upper level air temperatures exceed 1,100 degree F, or flames project out the door opening.
Test Findings: (1) The flames did not reach the ceiling during the 40-kW exposure (2) During the 150-kW exposure,
flashover did not occur. The maximum average upper-level temperature was 858 degF, the maximum heat flux at
floor level was 3.49 kW/m2. The flames did not project out the room door opening or to the outer extremities of the 8
x 12 ft walls.
Test Conclusions: Based on the findings listed above, the 100% natural sisal fiber, flame retardant treated
wallcovering without backing, identified as No-Flame Sisal Wallcovering, meets the acceptance criteria as
specified for the fully-lined protocol , when tested adhered to unprimed 0.5 inch thick Type X gypsum wallboard
with Sisal Adhesive #1-422.
Test 2
ASTM E84 Class A Flame Spread and Smoke Contribution. Standard test method for surface burning characteristics
of building materials.
Testing: Commercial Testing Company, Dalton Georgia
Test Conclusions: Flame Spread Index 20 , Smoke Density 0

| Maintenance |
Sisal wall covering is resistant to scuffing marks and dirt prints caused by hand or shoe contact. Since it is non-static,
natural fiber, dirt and dust are not attracted to it. The heavy texture makes it an undesirable writing surface for
ballpoint pens. The durable resilient fiber does not tear or rip when furniture or carts are pushed into the wall.
Periodic vacuuming in some buildings may be required to remove dust buildup near air ducts. Clean in these areas
as you would when vacuuming upholstery.
Sisal Guard fiber sealant can be spot applied in areas that are susceptible to constant oily hand contact. Examples
of such areas are near furniture settings, doorway openings, electrical switch plate areas, elevators and its lobbies,
and where people regularly lean against the wall.
The Sisal Guard will not discolor the sisal and can be used repetitively.
When wet mopping or shampooing the floor, keep water splashes off the sisal wall covering. Dirty water will leave a
mark.
Adhesive Removal:
DO NOT ATTEMPT TO WIPE OFF, DILUTED ADHESIVE WILL ABSORB INTO WALLCOVERING, LEAVING A
STAIN.
Remove excess adhesive with flat blade tool without pressing into wallcovering-scrape dried adhesive 24 hours later
Spot Removal
DO NOT SATURATE WITH WATER AND DETERGENT SOAP.
Use Sisal Care fiber cleaner or Use a foam aerosol cleaner (dry cleaner) such as used on upholstery
A stiff bristle brush can be used with these cleaners without harming the wall covering
Scrape dried food spots with a dull knife, it will not harm the wall covering
Stain Removal:
Permanent stains caused by asphalt, paint, shoe polish, color chalk, cosmetics, oil-based markers.
Dampen a clean white towel with a small amount of cleaning solvent to break down the stain. Blot up the stain working
toward the center, dry the area quickly. Some stains may not be able to remove entirely.

ASTM D3273 Standard Test Method for Resistance to Growth of Mold on the Surface of Interior
Coatings in an Environmental Chamber
Final ASTM Rating: 8
Testing: Environ Laboratories, Minneapolis Minnesota
Purpose: Testing to provide a basis of comparative performance results under controlled lab conditions.
VOC of Antimicrobial Additives:
sisal wallcovering : no additives utilized
sisal adhesive #1-422: 0 VOC
Comparisons:
Standard untreated gypsum wallboard and ceiling tile rating is 0 (heavy to disfigurement mold growth,
When treated with antimicrobial additives, gypsum wallboard typical industry rating is 8

Abrasion Resistance of Wallcovering
ASTM F793-93 Standard Classification of Wallcovering by Durability Characteristics
This test covers the classification of wallcovering by durability characteristics, that is, according to its serviceability
in use, recognizing that certain wallcovering is designed primarily for decorative effect, while
other wallcovering is also designed to achieve a high degree of serviceability.
ASTM Rating: Class 1, full commercial serviceability
Tear Resistance of Cloth
ASTM D2261-96 Standard Test Method for Tearing Strength of Fabrics by the Tongue (Single Rip)
Procedure (Constant-Rate-of-Extension Tensile Testing Machine)
This test method covers the measurement of the tearing strength of textile fabrics by the tongue (single
rip) procedure using a recording constant rate-of-extension-type (CRE) tensile testing machine.
ASTM Rating: warp 139 / fill 176

| Acoustic |
ASTM C423-00 Standard Test Method for Sound Absorption and Sound Absorption Coefficients by
the Reverberation Room Method
Testing: Riverbank Acoustical Laboratories, Geneva Illinois
Final Report: RAL A86-286
Test Mounting type B (direct to test surface). Used to determine minimum NRC rating of the sisal wallcovering.
Results: NRC: .15
Improved NRC ratings occur with actual installation of sisal wallcovering to gypsum wallboard, plywood,
furred walls, acoustic panels.
