Mainstay DS-5-S provides protection against corrosion in concrete structures and exhibits a number of superior properties: toughness, permanent flexibility, and improved chemical and temperature resistance. The absence of solvent reduces shrinkage, cracking, and disbonding and eliminates the problems related to solvent entrapment. Mainstay DS-5-S is particularly well suited for use as a topcoat over Mainstay ML-72 or Mainstay ML-72F Sprayable Microsilica Mortar.
