  • When recoating Sika® Armatec®-10 ZR with itself, the minimum recoat time is 2 hours at 70°F (21°C).
  • Do not leave the primed surfaces uncovered for longer than 3 days before applying cementitious repair materials or concrete.
  • Sika® Armatec®-10 ZR can stay exposed for a year. It must be scarified or recoat before applying cementitious repair materials or concrete.

* Tack Free times will vary with surface temperature, humidity and film thickness.  Allow Sika® Armatec®-10 ZR to dry for a minimum of 1.5 hours (or Tack Free to the touch) before the repair mortar or concrete is applied.
Consumption

Coverage

70 - 100 ft2 (6.5 - 9.3 m2) per unit; approximately 3 mils dry film thickness (DFT) per coat

(Coverage rates do not include allowance for surface profile or material waste.)
Application steps

MIXING

  • Sika® Armatec®-10 ZR must be stirred or shaken thoroughly before application.
 

APPLICATION

  • Use a 3/8" (10 mm) nap roller or a round brush.
  • Apply one coat (5 mils wet film thickness) onto a dry, rust-free surface.
  • Take special care to properly coat the underside of the totally exposed, mechanically prepared steel.
  • Allow Sika® Armatec®-10 ZR to dry for a minimum of 1.5 hours (or Tack Free to the touch) before the repair mortar or concrete is applied.
  • Pour or place cementitious repair mortar or concrete within 7 days maximum.
  • Sika® Armatec®-10 ZR can also be spray applied with either air spray or airless spray equipment,  Contact Technical Services for additional information.

CURING TREATMENT

  • Sika® Armatec®-10 ZR must be protected against contamination until installation of the cementitious repair mortar or concrete.
