Acclimate U-PLY panels 24 to 48 hours to the room environment in where they will be installed.

1. Install U-PLY printed side down before installing the finished floor.
2. Install the long dimension of the panel perpendicular to the floor joints for maximum rigidity.
3. Offset seams with sub-floor seam by at least 6". U-PLY scores and snaps with a knife for easy installation.
4. Stagger panels, ashlar fashion so that four corners do not meet. Offset underlayment joints by at least 16".
5. Leave a minimum 1/8" gap at walls.
6. Lightly butt all panels, but don't force sheets into place.
7. Fasted panels securely to a structurally sound, smooth, clean, and dry sub-floor with 18-gauge staples with chiseled ends and or 12-gauge non-staining galvanized ring.
8. Groove shank nails.
9. Make sure fasteners don't penetrate through the sub-floor into floor joist.
10. Position fasteners in the field on 4" centers.
11. Attach edge fasteners 1 1/2" apart and 3/8" from the edge.
12. Set fasteners flush or slightly below the panel surface.
13. Option1: Fill all edge joints and other service depressions with a Portland Based Latex Modified Patch and hand sand smooth. No belt sander needed, as we have pre-sanded U-PLY. Make sure patch is FULLY DRY before installing the finished floor.
    Options 2: Do not use patch at all, just make certain all panels are lightly butted together.
