QuietBoard Installation Instructions for Laminate & Vinyl Plank Flooring

QuietBoard Underlayment is specifically designed for use with floating vinyl plank, laminate, and engineered wood flooring products, offering detailed QuietBoard installation instructions for optimal performance. This sound-reduction underlayment system is easy to install and is suitable for use over most industry-approved subfloors, including 3/4” plywood, concrete, and OSB flooring.
Subfloor Preparation for QuietBoard Installation Instructions
Before starting the QuietBoard installation, ensure that all wood and concrete subfloors are flat within 1/8” over a 6’ span or 3/16” over a 10’ span. This flatness requirement applies to the seams of QuietBoard as well. Make sure the subfloor is clean, smooth, and free from dust and debris before installation.
QuietBoard Installation Methods
Floating QuietBoard Installation Instructions:
QuietBoard can only be floated when paired with a floating floor covering that is at least 4mm thick. Here’s how to install it:
- Begin by laying panels of QuietBoard perpendicular to the flooring direction, ensuring the panels are butted tightly together.
- Stagger the panels at approximately 50% to eliminate a grid-style layout.
- Leave a 1/4” expansion gap at all perimeter walls.
- Tape all continuous seams using high-quality duct tape that is at least 2 inches wide.
- Install the flooring perpendicular to QuietBoard following the flooring manufacturer’s instructions.
Glue-Down QuietBoard Installation:
For planks less than 4mm thick, a glue-down installation is required. Follow these steps:
- Apply a high-quality pressure-sensitive adhesive using the recommended trowel size from the adhesive manufacturer.
- Lay the panels of QuietBoard perpendicular to the flooring direction, ensuring they are butted tightly.
- Install QuietBoard panels while the adhesive is still wet.
- Roll the panels with a 75lb-100lb roller to ensure a full bond is made.
- Stagger the panels at approximately 50%, avoiding a grid-style layout.
- Leave a 1/4” expansion gap at all perimeter walls.
- Prepare all seams according to the flooring manufacturer’s recommendations. Improper seam preparation will void the warranty.
Note: We do not recommend taping seams for glue-down installations.
Final Steps for Installing Flooring Over QuietBoard
Once QuietBoard is installed, always follow the flooring manufacturer’s specifications for installing the final product. For both floating and glue-down methods, ensure the flooring is installed perpendicular to the QuietBoard panels for optimal results.
