Product details

Protect your SPC vinyl plank flooring with this 6-mil polyethylene moisture barrier underlayment, engineered specifically for SPC (Stone Plastic Composite) floating floor installations. Designed for use over concrete subfloors, this flat, non-cushioned underlayment helps block moisture vapor while maintaining the rigid support required for SPC click-lock systems.

Ideal for basements, slabs, and below-grade installations, this SPC underlayment provides reliable vapor protection without introducing flex or compression that can damage locking joints. Each roll covers 500 square feet, making it a cost-effective solution for residential and light commercial flooring projects.

Key Features & Benefits

  • SPC-specific underlayment designed for rigid core vinyl flooring
  • 6-mil polyethylene vapor barrier helps prevent moisture migration
  • Flat, non-compressible construction supports SPC click-lock stability
  • Suitable for basement flooring and concrete slabs
  • Helps reduce minor sound transmission without added padding
  • 500 sq ft coverage per roll for large-area installs
  • Easy roll-out installation for fast project completion

Best Uses

  • SPC vinyl plank flooring
  • Floating floor installations
  • Concrete and cement subfloors

Choose the right accessory

Use only the underlayment or moisture barrier approved for your flooring and subfloor. Extra padding is not suitable for every floor.

Questions before you buy

How many rolls should I order?

Measure the area to cover and check the coverage per roll. Allow for seams, overlap, and cuts as required by the installation instructions. Order whole rolls.

Can I add padding under my floor?

Only if the flooring maker allows it. Some floors have an attached pad and do not allow extra cushioning. A thin vapor barrier and a padded underlayment are different products.

How should I install it?

Follow the accessory and flooring makers’ instructions. Check the subfloor, gaps, fastening method, and fit before cutting or installing.

How will it ship?
