SEMI-PERMANENT Installation (with double-tape) See Re-Use-It Instructions for Long Term Semi-Permanent Instructions 1) Subfloor surface must be clean, dry, level and smooth, with all screw holes and seams filled or taped over. 2) Roll out flooring and let it acclimate to room temperature. Floor may be rolled inside out. Please make certain that the smooth side is up, and the foam or textured surface is down. Room temperature should be the highest temperature the room will reach when in use. (Remember, all those bodies working creates heat). Acclimatizing the floor may take anywhere from a few hours to a few days. 3) Make certain floor is lying flat to the subfloor and that all seams are even. Make all appropriate cuts. Leave a 1/2" (12.70 mm) gap between wall and a 1/16" (1.59 mm) gap between the seams. 4) Your floor should look like it is ready to be used. 5) Secure one end of each roll of flooring with weight so it will not move. 6) Roll the first roll closest to the furthest wall back onto its core and apply double face tape to the subfloor around the roll's perimeter and down the middle (2.5 ft, 3 ft or 3.25 ft (.73 m, .91 m or .99 m) from the edge). Leave all other rolls in place rolled out. 7) Re-roll out this roll to check the positioning over the tape. 8) If all is fine, roll up the floor, remove the protective paper from the double face tape and reroll over the exposed double face tape. 9) Repeat procedures 6 through 9 for each roll. 10) If necessary, use 75lb. roller to further secure floor. Caution: Change top tape every four months. Change double face tape every two years. Failure to do so can cause flooring to crack and ripple.
