Features & Benefits
- Ready-to-Use Product Features
- Advantages
- Convenient one and two gallon pre-proportioned units.
- Adheres to most materials used in construction.
- No by-products are generated during cure.
- Curing shrinkage is low.
- Long term dimensional stability is excellent.
- High tensile and compressive strength.
- Sure-cure in the presence of moisture.
- Resistant to the action of weathering, moisture, acids, alkalis and most other environmental factors.

- Applications
- Application Method
- Application Procedure
- Surface Preparation: The success of any adhesive application is directly proportional to the completeness of the substrate preparation and the care your crews put into the application. Remove rust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, and disintegrated materials from surfaces. Approved mechanical methods are recommended. Sandblast steel to appropriate finish.
- Proportioning: Preproportioned one gallon & two gallon kits are standard. Custom packaging available. Mix by volume - 2 1/2 parts A to 1 Part B. To bond fresh concrete to hardened concrete - Apply by brush, roller, broom or spray. Place fresh concrete while CBC IV is still tacky. If coating cures to the point where it is no longer tacky, recoat with additional CBC IV and proceed.
- Mixing: Proportion components into a clean pail and mix for approximately 3 minutes with a jiffy mixer (or equivalent) on a low-speed (400-600 rpm) drill until color is a uniform blend. Pilgrim EM CBC IV is designed for application both neat and as mortars. Proportion of aggregate to mixed epoxy varies with proposed end use. A 1 1/2 to 2 parts aggregate to 1 part mixed EM CBC IV is a general recommendation.
- Cure Schedule: 7 days @77°F to achieve max. physical properties.
- Clean Up: Pilgrim #5 CLEANER is formulated to remove uncured material from tools and equipment. Do not allow material to harden on tools.
- 1 gal. unit neat (no aggregrate) will cover approximately 100 sq. ft.
- 1 gal unit of EM CBC IV with 2 gallons of aggregate yields 462 cu. inches of grout.
- Cautions/Limitations
- Aggregate must be oven dried to avoid encapsulation of moisture.
- Do not thin EM CBC IV - Solvents will prevent proper cure. Exposure to temperatures (after cure) above 200°F dry and 130° wet not recommended. Substrate temperature must not be below 32°F during application to avoid possibilities of ice crystals inhibiting bond.
- Pot life is dependent upon material temperature and quantity mixed. The greater the mass the shorter the pot life.
- Coverage
