We are pleased to bring you the following IronPly® related frequently asked questions. Still have a question not answered? Reach out to us here.
IronPly® 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 IronPly Premium 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 subfloor. The faces of the IronPly® plywood underlayment panels have a fastener pattern that is designed to go up.
Yes. Please see the specific instructions on fastening IronPly® plywood underlayment panels that are available in the individual product Installation Guides available at www.IronPly.com.
Yes, you can use galvanized flathead wood screws. Do not use drywall screws. Make sure screw selected has a minimum 3/16" head. The screw you choose should not penetrate through the bottom of the subfloor.
IronPly® 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 IronPly® 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 IronPly® Premium Underlayment Installation Guide or by watching our Plywood Underlayment Installation Video.
IronPly® plywood underlayment can be used under ceramic tile.
No. Do not glue IronPly® plywood underlayment panels to the subfloor. Gluing plywood underlayment panels to the subfloor 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 subfloor in this manner.
No. Do not glue IronPly® 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.
Yes. All the hardwoods in IronPly® plywood underlayment come from plantations and sustainable sources. IronPly® plywood underlayment panels contain no tropical hardwoods or species from endangered forests. Go green with the Patriot Timber Family of Panel Products.
