Install leading brand pad with built in moisture barrier – 2 in 1 or 3 in 1.
Follow pad manufacturers instructions.
An exterior wall is usually the straightest and best reference line to start the installation. Direction of finished flooring should be at right angles to the floor joists whenever possible. Establish a starting line by leaving a minimum 1/2” expansion gap around all vertical obstructions. Measure this distance from the starting wall (in at least two places) close to the starting wall’s opposite corners. Mark these points and snap a working chalk line parallel to the starting wall allowing the required expansion space between the starting wall and the edge of the first row of flooring. To maintain the expansion gap throughout the installation, use 1/2” spacers between hardwood flooring board and wall or other object.
Boards should be installed left to right with the edge of the groove lined up against the chalk line, side-tongue facing out to the right. Whenever possible, the tongue along with width and length of the board should be facing out so that the tapping block or pull tool always uses the tongue of the flooring. If the groove is facing out and a tapping block or pull tool is used, the edge of the board may be damaged.
For the best performance of your floating floor, use a stair- step pattern installation, staggering seams 12” to 15”. No two end joints should be within three rows of each other.
Install first two rows by applying a thin bead of glue in the groove on the side and end of each board. Press each board firmly together and lightly use a tapping block if necessary. Clean excess glue from between boards with a damp cloth or mineral spirits. Tape each board together at side and end seams using 3-M Blue Tape. Allow glue to set before continuing installation of subsequent rows.
Always remember to allow for the expansion gap and clean excess glue from between boards. Often the last row will not end with a full plank. When this happens, place a full row of planks on top of the last row installed. Insert a 1/2” spacer against wall, and using a full width plank, trace distance from wall onto final row. Cut planks for final row to designated width. Apply glue and fit into place. Trim excess polyethylene film and/or padding so it will not be visible once moldings are installed. Tape may be removed within one hour. Allow 12 hours before placing furniture on floors and 24 hours before introducing heavy objects or full traffic.
