Interior Flooring Manual
End Curl End curl can occur if the flooring is not allowed to fully acclimate or lay flat prior to installation, or it may be the result of the material being tightly wound on the core, most noticeable at the core end of the roll. End curl is normal and may be addressed during installation. One or more of the recommendations below may be used to address end curl. The flooring may be softened with a heat gun on a low enough temperature to avoid damaging the flooring, but warm enough to make it more pliable. If possible, the roll’s cardboard core may then be used to reverse roll the material (face in) for a foot or two. Avoid rolling the material up into a tighter roll than the core’s diameter to prevent any unintentional damage. For high gloss flooring (products will typically have UV in their name), do not use the core and only gently work out the end curl manually. If using the #813 adhesive, use a 1/4 in. (6.4 mm) nap roller as detailed in the TDS to apply the adhesive to both the back of the flooring and the substrate. This will provide a much higher tack than normal, and it should be sufficient to overcome most curling. For all adhesives, weigh down the affected area by placing a piece of smooth, clean plywood over it and then adding additional weight, just enough to apply even pressure to the area. Leave the plywood and weight in place until the adhesive has fully cured. Seaming to Other Flooring Types Lonseal flooring can usually be chemically or heat welded to most other sheet vinyl flooring of similar thickness using Lonsealer or welding thread. However, where this is not possible, apply a 3 in. (7.6 cm) band of #650 epoxy adhesive beneath the Lonseal flooring at the transition, and consider installing a transition strip to further protect the seam. Note: It is recommended to test the planned seaming method on scrap material of Lonseal flooring and the other sheet vinyl flooring prior to installation. If a strong bond is not possible, use of the #650 as noted above is highly recommended to minimize the chance of seam separation. Installation Guides Lonseal flooring may be installed in a variety of settings, from healthcare and gymnasiums to aircraft and boats. Special installation instructions for these types of applications may be obtained at www.lonseal.com , and are meant to be supplemental to this manual. Below is a list of the Installation Guides (IG) currently available: Aircraft: for use with all aircraft installations (airplanes, helicopters, etc.) This guide may contain additional or differing installation requirements from this manual. This is intentional, and this guide will supersede the requirements in this manual where it differs. The use of Lontape is covered by this guide, and is suitable for installations where permanent floor installations are needed or allowed. Elevator: for use with all installations in passenger elevators This guide may contain additional or differing installation requirements from this manual. This is intentional, and this guide will supersede the requirements in this manual where it differs. Freight elevators may not be suitable for resilient flooring, due to the type of traffic and loads to which the flooring will be subjected. Exhibits & Show Floors: for use with temporary or short-term installations This guide may contain additional or differing installation requirements from this manual. This is intentional, and this guide will supersede the requirements in this manual where it differs. The use of Show Tape for temporary installations is covered by this guide. Please be aware that temporary installations using Show Tape will have modified limited warranty terms. Fitness Flooring: for use with Lonseal’s fitness flooring (Loncourt I, Loncourt UV, Lonwood Performa, and Lonwood with Foam) This guide also includes the application requirements for game line paints and installation in areas with retractable bleachers. Hot yoga studio installations should use the appropriate guide noted on page 15. Fixtures: for use with all cabinet, counter, display, or fixture installations This guide may contain additional or differing installation requirements from this manual. This is intentional, and this guide will supersede the requirements in this manual where it differs. Flash Coving: for use when flash coving Lonseal flooring While this is not a comprehensive guide for flash coving installations, it will provide minimum requirements and recommendations.
