SUBSTRATE and TESTING REQUIREMENTS:
• Forbo V 885 can be used on all grade levels of concrete, approved suspended wood floors and approved existing resilient floors. 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.
• 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 – 10 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 surface pH of the concrete must not exceed a pH of 10.0. Concrete surfaces with pH readings less than 7.0 or above 10.0 will require remediation prior to installation.
• The internal relative humidity must not exceed 85% as determined by testing conducted in strict accordance with the latest version of ASTM F 2170.
• The moisture vapor emission rate must not exceed 8.0 lbs. per 1,000 square feet in 24 hours as determined by testing conducted in strict accordance with the latest version of ASTM F 1869.
• 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.
INSTALLATION RECOMMENDATIONS:
1. Areas to receive material should be clean, fully enclosed and weather tight. The permanent HVAC should be fully operational and controlled and set at a minimum temperature 65o F (18.3o C). If this is not possible, the areas should be acclimated and controlled by means of temporary HVAC to the service level conditions expected during occupancy. The temperature and humidity should range from 75o F ± 10o F (23.9o C ± 5.5o C) with a 50% ± 10% ambient relative humidity. These conditions MUST be established at least seven days prior to beginning the installation, maintained during the installation, and continued for at least seven days following the installation.
2. The substrate must be free of all foreign materials including, but not limited to, dust, solvent, paint, wax, oil, grease, residual adhesive, adhesive removers, film-forming curing compounds, silicate penetrating curing compounds, sealing, hardening, or parting compounds, alkaline salts, excessive carbonation or laitance, mold, mildew, and other foreign materials that might affect the rate of moisture dissipation from the concrete, the adhesion of resilient flooring to the concrete or cause a discoloration of the flooring from below.
3. Before beginning the installation, all testing requirements should be conducted: concrete porosity, pH, internal relative humidity, moisture vapor emissions and bond testing. Refer to the Substrate Evaluation and Preparation section of the Forbo Installation Guide for additional information.
4. Trowel recommendation: 1/32” x 1/16” x 1/32” fine notch trowel. Replace the trowel when proper coverage is no longer attainable.
5. The open time and working time of adhesives will vary depending on site conditions such as ambient temperature and humidity, the porosity of the substrate and air circulation. A general indication of proper open time is when a light touch produces transfer of adhesive to the finger, but a firm touch will flatten and “smear” the adhesive.
6. Install one sheet at a time. The adhesive should be allowed to develop body before placing the flooring material into the adhesive, but DO NOT ALLOW THE ADHESIVE TO DRY. The flooring material MUST always be placed into wet adhesive and rolled immediately. The flooring material must also remain in contact with the adhesive while the adhesive is drying and curing. Proper placement and rolling will result in a complete “explosion” of the trowel ridges, creating a continuous flat film of adhesive on the substrate and on the material backing.
NOTE: When installing over a non-porous substrate, please refer to Forbo Technical Bulletin “Installing Forbo Sheet Vinyl Products over Non-Porous Substrates.”
7. Check for adhesive transfer frequently; there must be a 100% wet transfer of adhesive to the material backing in order to achieve a secure bond.
8. Immediately roll the flooring in all directions using a 100 pound roller to ensure proper adhesive transfer. Additional rolling is required during adhesive setup to ensure that the material is flat and fully adhered.
9. Remove fresh adhesive residue immediately with a clean white cloth. Dried adhesive can be removed with a clean white cloth and a properly diluted solution of neutral pH cleaner or with Forbo Adhesive Remover. The area must then be rinsed with clean, cool water to remove all residue from the floor. Refer to the Forbo Commercial Floor Care Guide for further information.
10. Keep the lid on the pail when not in use.
11. Do not allow heavy traffic or rolling loads for a minimum of 72 hours following the installation. Additional time may be necessary if the installation is over a non-porous substrate.
12. In order to allow the adhesive to dry and cure properly, wait a minimum of five days following the installation before conducting wet cleaning procedures or initial maintenance. Additional time may be necessary if the installation is over a non-porous substrate.
