- Concrete on (all grade levels) according to ASTM F710 and Preparation of Concrete Subfloors
- Suspended Wood and Wood Underlayments
- Existing well-bonded resilient flooring; not perimeter-bonded or cushion-backed. single layer, fully adhered
- Radiant-heated subfloors where the surface temperature does not exceed 85oF (29o C)
- Make sure the subfloor is clean, flat, dry and sound. It is important that the subfloor is free of all debris. Check the subfloor for unevenness or protruding objects such as nails or screws.
- When installing over concrete, the concrete must be dry with moisture vapor emission rate not exceeding 7 lbs. per 1000 square feet per 24 hours as measured by the Calcium Chloride Test and 93% RH using In-situ Probe.
- Begin in a corner and install the underlayment parallel to the wall in the opposite direction you plan to install the flooring planks. Leave at least 2˝ of excess underlayment up the wall and trim after completing the floor installation. See below for additional installation details.
- Roll out the next roll of underlayment in the same manner, making sure that the foam seams are butted together. The use of clear 2˝ wide packing tape can be used to attach the seams.
- When installing Armstrong Quiet Comfort™ Luxury Flooring Underlayment on concrete or below grade subfloors, be sure to tape the seams together with 2˝ tape that meets the moisture vapor transmission rate for this type of installation.
- All LVT products floating should not be exposed to direct sunlight for prolonged periods. It can result in discoloration and excessive temperatures that may cause expansion. The use of drapes or blinds is recommended during peak sunlight exposure. If drapes or blinds are not going to be used and expansion occurs in this area, we recommend adhering this area with S-995, S-295, or S-1000 Adhesive using the fine notch trowel. If using S-1840 underlayment in these areas, the underlayment must be adhered to the subfloor and the LVT adhered to the underlayment.
- Install the flooring according to Armstrong’s installation instructions.
- Do not use with S-315 Roll Strong or S-319 Roll Strong
