A versatile solution for indoor and outdoor structural flooring with Hardie™ Secura™ Flooring

Hardie™ Secura™ Flooring now offers a versatile solution for both interior and exterior applications, streamlining stock management and installation. This durable yet lightweight structural flooring can be installed over timber or steel joists and supports achieving a 7-star energy rating.

Ideal for wet areas, Hardie™ Secura™ Flooring features a surface sealer that reduces moisture penetration by causing water to bead on the surface rather than soak in, providing excellent moisture resistance. Unlike plywood or particle board, it can be tiled directly without underlay, eliminating height differences between floor finishes. Its tongue-and-groove joints simplify installation, reducing the need for timber trimmers, and the product can be gun nailed without pre-drilling, helping to save on installation time.

Easy to install, moisture-resistant flooring solution

Hardie™ Secura™ Flooring features a moisture-resistant surface sealer, eliminating the need for full floor waterproofing outside enclosed shower areas. Unlike plywood or particle board, it allows tiles to be laid directly onto the surface without underlay, avoiding uneven height differences between floor finishes. Its tongue-and-groove joint simplifies installation, removing the need for timber trimmers and speeding up the build.

Additionally, Hardie™ Secura™ can be gun nailed directly to the floor without pre-drilling, saving valuable installation time while providing a strong, stable foundation ideal for wet and dry areas. This makes it a reliable, efficient choice for modern homes and commercial projects where durability and performance matter.
