PENNTROWEL 250 Surfacer is a pigmented high performance silica filled epoxy based monolithic floor topping. It has been formulated with the most up-to-date resin technology to withstand high temperatures and thermal cycling. It exhibits excellent chemical, abrasion, and impact resistance. PENNTROWEL 250 Surfacer meets or exceeds ASTM C-722 for both types A & B chemical resistant resin monolithic surfacing's. PENNTROWEL 250 Surfacer employs a tight graded matrix and is self sealing. Surface sealing and cleanability is improved, however, with the addition of top coat of PENNTROWEL 250 Resin/Hardener. The top coat can then be optionally seeded with # 12 sand to adjust the surface texture if desired. Consult Corrosion Engineering specification CES-310 for complete usage/installation details.
