SpiderLath Fiberglass Lath

SpiderLath Fiberglass Lath — Lightweight, Rust-Free Metal Lath Alternative for Masonry, Walls, Flooring & Countertops

SpiderLath is a fiberglass-based lath system engineered as a direct alternative to standard metal lath for masonry, wall, flooring, and countertop applications. Designed for both commercial and residential construction, it eliminates the handling hazards and corrosion risks associated with traditional metal lath while delivering superior strength. Each 50 ft. x 2 ft. roll covers 100 sq. ft. — equivalent to approximately 5.5 sheets of standard metal lath — reducing material handling, storage space, and installation time on the job site. SpiderLath is an industry-approved solution recommended by professional users and brands seeking to reduce labor costs without sacrificing durability.

Technical Specifications

Unlike standard metal lath, SpiderLath will not rust or corrode, eliminating long-term degradation concerns in moisture-exposed applications. Its fiberglass construction surpasses the strength of 2.5 metal lath while being significantly lighter and safer to handle, making it a practical upgrade for crews looking to reduce material costs and improve job-site efficiency.

Key Features & Benefits

Up to 50% Faster Installation

SpiderLath installs up to 50% faster compared to standard metal lath, directly reducing labor hours on the job. The flexible roll format allows it to be cut and positioned quickly on any surface without the awkward handling associated with rigid metal sheets.

Rust-Free Fiberglass Construction

Manufactured from fiberglass, SpiderLath will not rust or corrode over time — a critical advantage in wet or high-humidity environments such as countertops, bathrooms, and exterior masonry. This eliminates the risk of rust staining through finished surfaces that can occur with metal lath.

Superior Strength

SpiderLath surpasses the strength of 2.5 metal lath, providing a reinforcement layer that minimizes cracking in finished surfaces. Contractors get a more durable substrate without the added weight or handling difficulty of heavier metal alternatives.

Lightweight & Compact Roll Format

At just 6 lb per roll and packaged in a 6 x 6 x 24 in. box, SpiderLath is easy to transport, store, and maneuver on the job site. A single roll replaces approximately 5.5 sheets of standard metal lath, significantly reducing the number of units a crew needs to carry and stage.

No Sharp Edges — Safer to Handle

Traditional metal lath presents a cut hazard during handling and installation. SpiderLath's fiberglass construction has no sharp edges, reducing the risk of hand and arm lacerations and lowering the need for heavy gloves that slow down installation work.

Versatile for Commercial & Residential Applications

SpiderLath is suitable for a wide range of masonry, wall, flooring, and countertop applications across both residential and commercial projects. Its consistent performance across substrate types makes it a single-product solution for multiple trades on the same job site.

Common Applications

Masonry Reinforcement

SpiderLath serves as a direct metal lath alternative in masonry applications, providing a strong, corrosion-resistant reinforcement layer for stucco and mortar systems.

Wall Substrates

Use SpiderLath as a lath base for interior and exterior wall finishes, including plaster and scratch coat systems, where rust-free performance is essential for long-term finish integrity.

Flooring Underlayment

SpiderLath can be installed as a reinforcement layer in flooring applications to help minimize cracking and improve the bond of mortar-set tile and similar floor finishes.

Countertop Construction

Ideal for concrete and mortar-based countertop builds where moisture exposure makes rust-prone metal lath a liability. SpiderLath provides the structural reinforcement needed without corrosion risk.

Compatible Materials

• Masonry and stucco systems
• Plaster and scratch coat wall finishes
• Mortar-set tile flooring
• Concrete and mortar-based countertops
• Interior and exterior wall substrates
• Commercial and residential construction assemblies

Frequently Asked Questions

Q: How does one roll of SpiderLath compare to standard metal lath sheets in terms of coverage?
