SurePly® plywood underlayment comes with a lifetime warranty for residential and nonrated commercial applications. SurePly® plywood underlayment panels are warranted as plywood underlayment for resilient flooring, vinyl composite tile, ceramic tile, carpet, engineered flooring, and wood floors. Please see our SurePly plywood underlayment Warranty for full details.
The Flex and Look Test is a simple but important procedure that only takes a few seconds and should be applied to any underlayment panels prior to installation. Flexing the panel will help to reveal any delamination or core irregularities. Panels with these defects should be replaced prior to use.
The label side goes down to the structural sub-floor. The faces of the SurePly® plywood underlayment panels have a fastener pattern that is designed to go up.
Yes, you must put a staple or screw in every “x”. The minimum spacing requirement is every 4” on center in the body of the panel and every 2” along the panel perimeter to properly secure SurePly® panels to the sub-floor. This will eliminate potential flooring issues resulting from insufficient and incorrect fastener placement. In order to remain within the terms of the SurePly® warranty, follow the specific installation instructions available at www.SurePly.com.
Yes, you can use coated flathead or bugle head wood screws. Do not use drywall screws. Make sure the screw selected has a minimum 3/16” diameter head. The screw you choose should not penetrate through the bottom of the sub-floor. You must install a screw in every “x” (every 4” on center in the body and every 2” along the perimeter) on the face of the SurePly® panel.
SurePly® plywood underlayment panels should acclimate 24 to 48 hours in a heated home environment of approximately 70 degrees Fahrenheit.
We have found the easiest method is to heat the label with a hairdryer prior to removal. If there is any residual adhesive, you can remove it using either Naphtha, Goo Gone®, mineral spirits or by lightly sanding the area.
No. Our preferred method is to lightly butt the panels together for a patch-free installation. The second method is to leave an expansion joint, approximately the thickness of a nickel, between the panels, and fill the seams with a Portland Cement-based seam filler. Please note you may leave an expansion joint without seam filler when the SurePly® plywood underlayment panels are installed under carpet, engineered floors, or wood floors. We strongly recommend you read our full instructions on using seam filler and how to prevent telegraphing seams in our SurePly® Premium Underlayment Installation Guide or by watching our SurePly® Premium Underlayment Installation Video.
SurePly® plywood underlayment can be used under ceramic tile.
No. Do not glue SurePly® plywood underlayment panels to the sub-floor. Gluing plywood underlayment panels to the sub-floor can cause problems such as a tack and release floor that crackles when you walk across it. In addition, gluing the underlayment panels to your structural sub-floor will eliminate the opportunity to remove the underlayment for a future floor replacement. We do not warrant our underlayment panels that have been glued to the sub-floor.
No. Do not glue SurePly® plywood underlayment panels to a concrete substrate. Gluing plywood underlayment panels to concrete can cause problems such as a tack and release floor that crackles when you walk across it. We do not warrant underlayment panels that have been installed over a concrete substrate in this manner.
Yes. However, make certain the existing floor is a sound, level, clean, and solid structure before putting another floor on top of it.
No. SurePly® plywood underlayment panels are made with exterior glue, but the panel is not made to Marine Grade plywood specifications.
Yes. All the wood veneers in SurePly® plywood underlayment come from plantations and sustainable sources. SurePly® plywood underlayment panels contain no tropical hardwoods or species from endangered forests. Go green with the Patriot Timber Family of Panel Products.
