Application

Application Information

Ambient Air Temperature

45°- 120 °F (7° - 49° C)

Relative Air Humidity

Minimum 20% / Maximum 90%

Substrate Temperature

45°- 120 °F (7° - 49° C)

Steel temperature should be at least 5° F (3° C) above the measured dew point temperature.

Pot Life

• 24 hours at 77° F (25° C) and 50% R.H.

This is a moisture cure product. Presence of moisture after opening and during use will shorten application time. When feasible, keep containers of material covered during use.

Waiting / Recoat Times

• 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.

CLEANING OF TOOLS

• Clean all tools and application equipment with approved solvent (e.g. Acetone, MEK or Xylene) immediately after use, before Sika® Armatec®-10 ZR dries.
