Areas to receive material should be clean, fully enclosed and weather tight with the permanent HVAC in operation. A minimum temperature 68º F (20º C) should be established at least seven days prior to beginning the installation, maintained during the installation, and for at least seven days following the installation. The installation should not begin until the work of all other trades has been completed, especially overhead trades. Any areas to receive material should be adequately lighted to allow for proper inspection of the substrate, installation, seaming and for final inspection.
Material Storage and Handling
Areas where materials are to be stored should be a stable, conditioned environment as described under the Jobsite Conditions section. All materials and adhesives should be acclimated to these conditions for at least 48 hours prior to the installation. Material should be delivered to the job site in original, unopened packaging, with all labels intact. All rolls should be stored standing upright, labels up, to ensure that the color, roll and batch numbers can be easily read.
Proper adhesive application is essential for achieving a secure bond. Bulletin Board must be installed into wet adhesive. Always conduct adhesive mat bond tests before beginning the installation. Bond testing will aid in identifying both the working characteristics of the adhesive (open time and working time) for the site conditions, and also any potential bonding problems. Forbo recommends to use our L910W adhesive for any Bulletin Board installation. Place the material into the adhesive and roll while the adhesive is still wet enough to achieve a 90% - 100% wet transfer of adhesive to the material backing. Never allow the adhesive to dry to a point that wet transfer to the material backing does not occur.
