SikaTop®-121 Plus

Two-component, polymer-modified, cementitious leveling/pore sealing mortar plus FerroGard 901 penetrating corrosion inhibitor

SikaTop®-121 Plus is a two component, polymer-modified, leveling and pore sealing mortar with the additional benefit of FerroGard® 901, penetrating corrosion inhibitor. SikaTop®-121 Plus provides a smooth substrate, free of irregularities and bug holes for following protective coatings.

  • Excellent adhesion to concrete and mortar substrates
  • High flexural and compressive strengths
  • Increased density - improved carbon dioxide resistance (carbonation) without adversely affecting water vapor transmission (not a vapor barrier)
  • Increased freeze/thaw durability and resistance to deicing salts
  • Enhanced with FerroGard® 901, a penetrating corrosion inhibitor - reduces corrosion even in the adjacent concrete
  • Compatible with coefficient of thermal expansion of concrete - Passes ASTM C-884 modified
  • Can be applied over Sika® FerroGard® 903, corrosion inhibiting impregnation
  • Not flammable
