Metzger/McGuire Spal‑Pro RS 88, Clear

Spal-Pro RS 88 is a rapid-setting two-component polyurea polymer liquid of 100% solids content that is specifically designed to fill and protect contraction and construction joints in heavily trafficked industrial, commercial, and retail concrete floors.

In addition, this heavy-duty, semi-rigid polyurea can be used to fill random cracks in industrial floors.

When treating areas that can’t afford a great deal of downtime, Spal-Pro RS 88 is the ideal solution. Floors at 70˚F that have been treated with Spal-Pro RS 88 can be reopened to full traffic in as little as sixty (60) minutes and light traffic in thirty (30) minutes.

Use Spal-Pro RS 88 with confidence on polished and stained floors. This product will fill joints and cracks, and it won’t smudge or smear during grinding or polishing. Spal-Pro RS 88 maintains a consistent color profile and resists fading and discoloration, making it an ideal solution in areas where there is concern about the overall look of the floor. Spal-Pro RS 88 is non-staining in normal slab surface conditions, so it does not exhibit the residual concrete staining often associated with other semi-rigid fillers.

When cured, Spal-Pro RS 88 is a rubberlike solid with a hardness of Shore A86-90. Unlike other softer polyureas, RS 88 will provide superior edge protection and support.

Spal-Pro RS 88 is intended for use where final temperatures are from 32˚F (0˚C) to +120˚F (49˚C).
