Interior Flooring Manual
Installation Lonseal flooring must be installed in strict accordance with the requirements and recommendations noted throughout this manual and any other technical information related to the installation, including Technical Data Sheets (TDS) and Installation Guides (IG). Always ensure the most current revision of the document is being used. This includes printed labels and documentation included with adhesives and sundries, as revisions may have been made since their last printing. For these products, their TDS will supersede the information on the label or insert when it differs. All related products not branded by Lonseal must be installed per those manufacturers’ current instructions. Failure to do so may result in a failure of the flooring system to perform as intended. Installer Responsibility Although Lonseal products are closely inspected prior to shipping, if a problem becomes evident that cannot reasonably be worked around during the course of installation, STOP the installation and notify your supplier or Lonseal sales representative immediately. The installer must verify that all products are correct for the project, and ensure that the pattern, color, style, and lot numbers match those called for in the finish schedule as specified for the project. The installer must also verify that the site conditions will permit installation per Lonseal’s requirements. Before beginning the project, the installer should become familiar with all technical documents related to the installation, including Lonseal’s documents (manual, installation guides, TDS, SDS, bulletins, etc.) and documents from the manufacturers of all other products used for the installation. Further, the installer should become familiar with the tools and products to be used (adhesives, heat guns and nozzles, patching compounds, self-leveling underlayments, trowels, etc.). It is critical that all instructions for these products be thoroughly reviewed, noting all cautions, disclaimers, and warnings. Disclaimer: Installation of any Lonseal products constitutes acceptance of those products and all site-related conditions by the installer. If any issues arise from improper use or installation of Lonseal products, the installer bears sole responsibility for the installation, which may no longer be covered under any Lonseal warranty. This includes, but is not limited to, use of installation products or methods not suitable for sheet vinyl or contrary to Lonseal’s technical documentation, installation on unapproved subfloors or substrates, or installation of products with readily apparent or known issues. Prior to Installation Store all products in the installation area for a minimum of 48 hours prior to installation, with the flooring being kept in its packaging and standing on end. Storage and acclimation temperature must be between 65 – 85 °C (18.3 – 29.4 °C), with the relative humidity between 35 – 55%. The installation area must have an operating, permanent HVAC, or a system which provides proper control of both the temperature and humidity. The optimal acclimation environment will be the same as the one the flooring will occupy after installation is complete.
Note: If the flooring is not allowed to acclimate properly, expansion or contraction of the flooring may occur during or after installation. This can lead to issues like buckling, edge curl, gapping at the perimeter, or seam separation.
After acclimation, unroll and allow the flooring to lay flat. This process may take multiple hours, depending on previous storage temperature, acclimation temperature, and how tightly wound the material was on the roll. Allow extra length when cutting, as shrinkage may occur if temperatures are unstable from acclimation to installation. Disclaimer: Sheet vinyl is subject to a greater degree of dimensional change than vinyl plank or tile. Lonseal accepts no responsibility for dimensional changes to its flooring that is cut into shapes, not properly acclimated, or cut outside recommended environmental conditions. The amount of change will depend on the environment in which the flooring is cut versus the environment in which it is installed. Keeping the material acclimated in similar, if not the same, environments can help reduce or eliminate this natural occurrence, as can cutting the material slightly larger than needed, and trimming to the correct size just prior to installation. Laying Out Only some Lonseal flooring has a contrasting thread woven into the scrim backing cloth approximately 8 – 10 in. (20.3 – 25.4 cm) from the edge to help indicate roll direction. When removing flooring without this thread from the roll, always mark the back to note the roll direction with a pencil. DO NOT use marker, as the dye or ink can bleed to the surface of the flooring and cause permanent discoloration. When removing cuts, it is also important to indicate the order each cut was removed from the roll on the back of the flooring.
