Polyurea Crack Filler RS88 600mL Cartridge Kit by Metzger Gray

Description

Product Overview

The Metzger RS88 polyurea crack filler is engineered for demanding industrial environments where concrete floors endure constant stress from heavy equipment, forklifts, and high‑traffic activity. Packaged in a 600 mL dual cartridge, the product delivers a rapid‑setting, two‑component polyurea system that cures to a Shore A hardness of 88, providing a resilient yet flexible seal that can absorb movement without cracking.

Designed in compliance with ACI 302 recommendations for control joint fillers, this formulation is moisture‑insensitive, allowing it to bond effectively to both damp and dry concrete surfaces. The polymer matrix offers excellent resistance to chemicals, abrasion, and UV exposure, ensuring long‑term performance in interior settings where exposure to sunlight may occur. With a cure time of less than 60 minutes at 70 °F (21 °C), the filler enables rapid return to service, minimizing downtime for facilities that cannot afford prolonged interruptions.

Each cartridge provides approximately 24 linear feet of joint fill for a 1/4″ wide by 1/2″ deep joint, 16 linear feet for a 3/8″ wide joint, and 12 linear feet for a 1/2″ wide joint, giving users flexibility to address a range of joint dimensions with a single kit. The product’s color‑stable, standard gray appearance blends discreetly with most concrete floor colors, while maintaining visibility for inspection and maintenance.

Usage

Metzger RS88 is ideal for sealing control and construction joints in concrete floors of warehouses, manufacturing plants, distribution centers, and any facility where heavy wheeled equipment operates. The rapid‑setting nature makes it suitable for time‑critical repairs, such as fixing cracks during scheduled maintenance windows or after unexpected damage. Its high hardness and flexibility allow it to withstand the repetitive loading of forklift traffic, pallet jacks, and other material handling equipment without premature wear.

Because the formulation is moisture‑insensitive, it can be applied in environments with varying humidity levels, including damp basements or freshly poured concrete that has not yet fully cured. The filler can be shaved flush with the surrounding floor surface in as little as 15 minutes, creating a smooth, level finish that does not interfere with subsequent floor coatings, sealants, or polishing processes.
