FORBO SUSTAIN 1299 ADHESIVE TECHNICAL DATA RECOMMENDED FOR USE WITH: • Marmoleum® Sheet, Walton, Marmoleum® Composition Sheet (MCS), Marmoleum® Sport • Corkment Underlayment • Marmoleum® Modular, Marmoleum® Modular Striato, Marmoleum® Composition Tile (MCT) IMPORTANT!! Forbo strongly recommends that prior to the placement of concrete on site that concrete professionals are consulted regarding the terms for performance of the adhesive system listed below. This will ensure that the necessary and appropriate admix design is specified to eliminate any unnecessary cost or loss once the concrete slab has been poured. If the concrete surface does NOT meet the required level of porosity, failure may occur and such use voids the warranty of this adhesive. SPECIFICATIONS: • SCS-Certified 25% Post-Consumer Recycled Content (PCC) • Cradle to Cradle CertifiedTM at the Gold level. Cradle to Cradle CertifiedTM products are evaluated for material health, material reutilization, renewable energy use and carbon management, water stewardship, and social fairness.

All concrete substrates must be prepared in strict accordance with the conditions set forth in the latest version of ASTM F 710. The substrate must be dry, clean, smooth, and structurally sound. IMPORTANT! The installation of a permanent, effective moisture vapor retarder is a requirement of ASTM F 710. Forbo Sustain 1299 is not intended for use on slabs where no moisture vapor retarder is in place. For additional information, contact Forbo’s Product Support and Education Services. • Concrete surfaces that are hard troweled or tight must be mechanically abraded in order to create the necessary level of porosity for adequate adhesive performance prior to installation. • The concrete porosity should be determined by testing in strict accordance with the latest version of ASTM F 3191. Water should penetrate into the slab within 5 – 20 minutes to be considered acceptable. If water penetrates too rapidly or too slowly, adjustments to the concrete surface must be made to provide the proper surface profile. Concrete slabs determined to be overly porous, dusty or generally insufficient may need to be primed using a primer according to the manufacturer’s recommendations to regulate the porosity level of the slab and to meet the porosity conditions noted above. • The concrete surface must be dry and have a value of 5 or less when tested in strict accordance with the latest version of ASTM F 2659 using a surface moisture meter such as Tramex CME-4 or equivalent. • The surface pH of the concrete must not exceed a pH of 12.0. Concrete surfaces with pH readings less than 8.0 or above 12.0 will require remediation prior to installation. • The internal relative humidity must not exceed 99% as determined by testing conducted in strict accordance with the latest version of ASTM F 2170. • Conduct adhesive mat bond testing before beginning the installation. Bond testing will aid in identifying both the working characteristics of the adhesive, such as the appropriate open and working times for the site conditions, and also any potential bonding problems to the substrate.
