Sauereisen SewerGard No. 210FS is a fast-setting epoxy material for use in municipal wastewater environments. This lining protects concrete surfaces from chemical attack and physical abuse, while prohibiting water infiltration. It is particularly useful for protection of manhole benches, inverts and other structures subject to very little maintenance downtime. No. 210FS has non-sagging application properties that permit vertical and overhead applications, if necessary. When cured, No. 210FS provides an impermeable, high strength, corrosion-resistant lining. Suitable for application over damp or dry concrete surfaces, No 210FS does not require a primer. 412.963.0303,
