Premium Treated Plywood Underlayment

The Ultimate Foundation for Long-Lasting Floors

Build with confidence from the ground up. Our Treated Plywood Underlayment is engineered to provide a smooth, ultra-stable surface for your finish flooring while offering superior protection against moisture, rot, and fungal decay. Whether you are prepping a bathroom for tile or a kitchen for luxury vinyl, this is the professional’s choice for a flawless finish.

Why Choose Our Treated Underlayment?

Enhanced Durability: Pressure-treated to resist mold, mildew, and termites, making it ideal for moisture-prone areas like kitchens, bathrooms, and laundry rooms.

Sand-Sanded Surface: Features a consistent, smooth face that prevents "telegraphing"—ensuring seams and imperfections don’t show through your vinyl, linoleum, or carpet.

Structural Integrity: High-quality veneers and exterior-grade adhesives prevent delamination and buckling under heavy foot traffic.

Easy Installation: Lightweight and easy to cut, our panels are designed to reduce installation time and waste.

Best Used For:

Tile & Stone: Provides the rigidity needed to prevent grout line cracking.

Resilient Flooring: The smooth surface is perfect for LVP (Luxury Vinyl Plank) and sheet vinyl.

Moisture-Prone Zones: Basements and mudrooms where humidity levels fluctuate.

Pro Tip: For the best results, allow the panels to acclimate to the room's humidity for 48 hours prior to installation and use floor-rated fasteners to avoid "nail pop."
