MAPLE SHADE, NJ--Stonhard has introduced a spray-applied lining system for reservoirs, large tanks, cooling towers and other vertical applications in corrosive environments.

Stonchem 444 is a spray-applied, 100% solids, two-component, hybrid elastomer lining system designed for vertical and overhead applications.

Stonhard recommends the immersion-grade, waterproof lining for water and wastewater facilities, secondary containment areas, scrubber decks, tank farms, reservoirs, chutes and cooling tower basins.


Stonhard's newest lining is part of the Stonchem product line, designed for ultra-corrosive environments. The line also includes Stonchem 441 (pictured).

Stonchem 444 is UL approved for potable water storage tanks of 1,000 gallons or greater.

It can be applied over a broad range of substrates and environmental conditions at a nominal thickness of 30–120 mil/0.75 to 3mm.

The system has an optional non-skid surface and can be applied in cold environments.

Stonchem linings are seamless systems designed to protect substrates from a broad range of chemicals, including most petroleum-based products, salts, acids and alkalis. The product line was individually formulated to resist corrosion, abrasion and extreme temperatures.

Stonhard products are backed by Stonhard’s single-source warranty on both products and installation.
