Lions Floor SPC 6mil Underlayment

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.
