SurePly^® Premium Plywood Underlayment & Materials Preparation

Allow all materials used in your flooring installation to acclimate to the heated home environment, approximately 70°F, for 24 to 48 hours prior to use.
Store all panels on their 8' edge (separately if possible) to allow equal air flow over the face and back of the material.
Examine each piece of SurePly^® plywood underlayment using the Flex & Look Test.

Follow these steps:

Stand the panel vertically with its 4' edge on the floor and the panel face towards you (the staple/nail pattern will be facing you).
Grip the top panel edge with one hand and firmly place the palm of your other hand against the face of the panel.
Pull the panel down approximately 4” - 8' with your top hand while simultaneously pressing forward with the palm of your other hand approximately 4” - 8' until a noticeable curve is in the panel. Hold this position during inspection.
With the panel in this flexed position, thoroughly inspect the entire panel surface for imperfections, which will look like 'bubbles' or 'creases.' In the rare instance that you find such an imperfection, do not use the panel. Set it aside and contact Patriot Timber Products immediately for a resolution.

Structural SubFloor Preparation

Install SurePly^® plywood underlayment over a clean, dry, level, original sound structural subfloor, or existing floor.
Thoroughly scrape, sweep, and vacuum the entire surface and strip any wax from the existing vinyl.
Do not use any adhesive beneath SurePly^® plywood underlayment.

Positioning SurePly^® Premium Plywood Underlayment

Run SurePly^® plywood underlayment panels perpendicular to the floor joists.
Begin by laying out the floor in a corner of the room where you can get the greatest amount of coverage without having to cut the SurePly^® plywood underlayment panels. The face with the nailing pattern is designed to go up.
Position SurePly^® plywood underlayment panels 1/8' to 1/4' from the walls to allow for expansion.
The panels should be cut so that the factory edges go together at the seams in the field of the floor. Hand cut exterior edges for installation next to the walls.
Stagger SurePly^® plywood underlayment panels to create a 2' minimum offset between the SurePly^® plywood underlayment panel and subfloor seams.
There are two methods for installing the SurePly^® plywood underlayment. The first method, and our preference for all SurePly^® plywood underlayment installations, is to install the panels without an expansion joint and without a seam filler. We recommend you use this method for installation under vinyl, vinyl composite tile, luxury vinyl tile, ceramic tile, carpet, engineered flooring, and wood floors. For a SurePly^® plywood underlayment installation without an expansion joint, lightly butt the panels together without applying any pressure so they barely touch at the joints.The second method is to install the SurePly^® plywood underlayment panel with an expansion joint and using a seam filler. If you choose to install the SurePly^® plywood underlayment panel with a seam filler, leave a 5/64' gap, approx. the thickness of a nickel, between each panel. Then fill the seams according to the seam filler manufacturer's instructions.
Cut and place SurePly^® plywood underlayment on the subfloor without any fasteners, or 'dry fit' all panels first before beginning any fastening.
Plywood underlayment panels should be laid in an offset pattern as shown in the Flooring Diagram so that four corners never directly intersect.

Fastening SurePly^® Premium Plywood Underlayment

Do not use any adhesive on the subfloor beneath SurePly^® plywood underlayment.
We recommend a pneumatic fastener tool that incorporates an adjustable depth-drive control to prevent fastener 'blow-through' or 'over-driving.' If this feature is not available, adjust the air pressure on the compressor to an appropriate level to avoid fastener 'over-driving' or 'blow-through.'
You can fasten SurePly^® plywood underlayment by selecting one of the following options: Galvanized coated chisel-point staples with a 1/4' maximum crown or flathead wood screws treated with a moisture-resistant coating (such as galvanized or zinc). Do not use drywall screws. Do not select a fastener that is uncoated, cement or rosin-coated, as they may rust and discolor your finished floor. The length of the selected fastener should be a minimum of 5/8', but not so long that it protrudes through the bottom of the subfloor.
Stand on each plywood underlayment panel during fastening to ensure full contact with the subfloor. Any 'crackling' or 'popping' noises indicate debris is underneath the panel. Should this occur, stop the installation, remove and discard the panel, then scrape, sweep, and vacuum the subfloor again until all debris is removed.
All fasteners should be slightly countersunk below the surface of the new underlayment.
Fasten the 8' edge first at 2' on center - 1/2' from edge - starting from the corner of the room. Leave an expansion joint of 1/8' to 1/4' between the panel and the edge of the walls. Stand on the panel to ensure flush contact with the structural subfloor, and do not overdrive the fasteners.
Return to the starting corner and fasten the 4' edge at 2' on center - 1/2' from the edge of the panel.
Return to the starting corner and fasten the diagonal at 4' on center to the opposing corner.
Return to starting corner and fasten the 'field' of the panel every 4' on center working in a diagonal direction across the face of the SurePly^® plywood underlayment panel. Make sure to put a fastener in each 'x' as you work diagonally across the panel.
Fasten the remaining 4' edge 2' on center - 1/2' from the edge of the panel.
Finish the sheet by fastening the remaining 8' edge 2' on center - 1/2' from the edge of the panel. Note that the same procedure is used as well for the offset sheet which would start the next row of underlayment.

Using Seam Filler with SurePly^® Premium Plywood Underlayment

If you choose to install the SurePly^® plywood underlayment panel with an expansion joint, you must use a seam filler.* Check with your flooring supplier/manufacturer to be certain your seam filler is acceptable.
Do not 'floor-mix' seam fillers on top of the SurePly^® plywood underlayment panel face. Mix the seam filler separa
