Application

Application Information

A+B+C ~125 lb/ft³ (~2.0 kg/l)

65°-75°F (18°-24°C)

40-95 °F (5-35 °C)

40-95 °F (5-35 °C)

~ 90 minutes

Application Steps

• Sika® Armatec®-110 EpoCem can be mixed with a low-speed (< 250 rpm) electric drill mixer.
• Shake components A and B thoroughly before opening.
• Pour liquid components A and B into a suitable mixing vessel and mix for 30 seconds.
• While still mixing components A and B slowly add powder component C.
• Mix the three components together for a minimum 3 minutes until blend is uniform and free of lumps, minimizing addition of air.
• Mix only the quantity that you can be applied within the pot life.
• DO NOT ADD WATER.

As reinforcement corrosion protection

• Apply by stiff-bristle brush or spray at 80 ft² /gal.
• Take special care to properly coat the underside of the totally exposed steel.
• Allow coating to dry 2-3 hours at 73 °F, then apply a second coat at the same coverage.
• Allow to dry again before the repair mortar or concrete is applied.
• Pour or place repair within 7 days

As a bonding primer

• Apply using a stiff-bristle brush or broom. To achieve good bond, Sika® Armatec®-110 EpoCem must be applied well into the substrate, filling all pores and ensure complete coverage of all surface irregularities (minimum layer thickness 1/64″ (0.5 mm).
• Spray apply with Goldblatt Pattern Pistol or equal equipment.
• Apply the freshly mixed patching mortar or concrete wet on wet, or up to the maximum recommended open time, onto the bonding slurry.

Sika® Armatec®-110 EpoCem must be protected against contamination and rain until application of the repair mortar.

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
