Cementitious Bonding Agents - Sika® Armatec® 1C
BONDING PRIMER AND REINFORCEMENT CORROSION PROTECTION
Sika® Armatec® 1C is a cementitious, one-component, coating material with corrosion inhibitor, used as a bonding primer and/or for reinforcement corrosion protection.
- Easy to mix, just add water.
- User-friendly application
- Excellent adhesion to mechanically prepared concrete and steel.
- Performs as a corrosion inhibitor
- High shear strength
- Can be used on exterior, slab-on-grade surfaces.
- Excellent bonding bridge for cement based repair mortars.
- Long application life
- Can be brushed on, or applied using a textured pattern pistol, hopper spray equipment.
Usage
- Suitable as a bonding primer on cementitious mortar, steel, or when placing fresh, plastic concrete onto existing, mechanically prepared, saturated surface dry (SSD), hardened concrete.
- Suitable in concrete repair assemblies as reinforcement corrosion protection.
- Protection to reinforcing steel in areas of thin concrete cover where project documents, local building codes or ACI 301 "Specifications for Structural Concrete" recommendations for minimum concrete cover requirements may not have been met.

Application Steps
MIXING- Wet down all tools and mixing equipment prior to use.
- Pour 1 - 1.2 quarts (0.95 - 1.10 liters) of cool, clean water [approximately 70° F (21° C)] into a suitably sized and clean mixing container, using a calibrated measuring jug or similar, to ensure strict control of water content. Do not overwater.
- Mix mechanically with a low-speed drill (< 300 rpm) and mixing paddle or mortar mixer.
- Mix to a uniform consistency for a time typically not to exceed a maximum 3 minutes. Mix should be free of lumps.
- Refer to ACI 305R, "Guide to Hot Weather Concreting" & ACI 306R, "Guide to Cold Weather Concreting" when there is a need to place this product in hot or cold ambient and substrate temperature conditions. Thinner applications of cementitious repair mortars will be more sensitive to jobsite temperature conditions.
APPLICATIONAs a bonding primer
- Substrate must be Saturated Surface Dry (SSD). Surfaces should be damp with no standing water.
- Apply using a stiff-bristle mason's brush or spray. To achieve good bond, Sika® Armatec® 1C must be scrubbed well into the substrate, filling all pores ensuring complete coverage of all surface irregularities.
- Apply the freshly mixed patching mortar or concrete wet on wet, or up to the maximum recommended waiting time, onto the bonding primer.
As reinforcement corrosion protection
- Apply by stiff-bristle mason's brush or spray.
- Take special care to properly coat the underside of the totally exposed steel.
- Allow material to dry 2 - 3 hours at 73° F (23° C), then apply a second coat at the same coverage rate.
- Allow to dry again before the repair mortar or concrete is applied.
- Pour or place cementitious repair mortar or concrete within 7 days.
CURING TREATMENT- Sika® Armatec® 1C must be protected against contamination and precipitation until installation of the cementitious repair mortar or concrete.
