Spal-Pro RSF is a 100% solids, two-component heavy-duty, semi-rigid polyurea joint filler intended for use in filling and protecting contraction and construction joints in industrial and freezer/cooler concrete floors. RSF can be applied in temperatures as low as -30F (-35C).
Spal-Pro RSF was developed to fill and protect joints in concrete floors that are subject to hard wheels and heavy loads. Its primary function is to support such traffic and support joint edges. Spal-Pro RSF is designed for use in areas where final temperatures are from 120F (49C) to -30F (-35C). Spal-Pro RSF is also ideal for filling random cracks.
