Product Description

SikaEmaco 1061 (formerly MasterEmaco T 1061) is a one-component, shrinkage-compensated cement-based mortar engineered for horizontal concrete repairs requiring extended working time, rapid set, and durable results. Its formulation supports full- and partial-depth repairs, delivering low permeability, freeze/thaw resistance, and reliable adhesion on sound concrete substrates.

With SikaEmaco 1061, you get a repair mortar that balances workability and performance — providing ample time for placement and finishing without sacrificing structural strength or durability. After proper application, the surface can be coated in as little as 6 hours, allowing for quick return-to-service in commercial and industrial environments.

Benefits

  • Extended working time — easy to place and finish larger repairs without rushing
  • Rapid-setting and early strength gain — fast turnaround and reduced downtime
  • Shrinkage-compensated design minimizes drying shrinkage and bond-line stress
  • Low permeability — reduces chloride intrusion and enhances long-term durability
  • Freeze/thaw resistant — suitable for cold weather and harsh exposure environments
  • Can be used for full-depth and partial-depth repairs, structural or non-structural
  • One-component — just add potable water, no additional aggregate required (but may be extended if needed)
