Spal Pro RSF

Spal-Pro RSF is a 100% solids, two-component, heavy-duty semi-rigid polyurea joint filler designed to fill and protect contraction and construction joints in industrial and freezer/cooler concrete floors. Engineered for extreme conditions, RSF can be applied in environments as cold as -30°F (-35°C).

Developed for floors subjected to hard-wheeled traffic and heavy loads, its primary function is to protect joint edges and provide structural support without deflection. Spal-Pro RSF performs reliably across a wide temperature range—from -30°F to 120°F (-35°C to 49°C)—making it ideal for use in both ambient and sub-zero settings.

In addition to joint filling, Spal-Pro RSF is also effective for repairing random cracks, delivering long-lasting durability and performance in the most demanding industrial environments.
