Specifications
Applications
Super POR-Rok is used for both structural anchoring and concrete repair.
Common Uses:
- Anchor bolts and threaded rods
- Railings and guard rails
- Banisters and handrails
- Sign posts
- Machinery bases
- Structural steel connections
- Concrete crack repair
- General patching and void filling
Mixing & Installation
Mixing Ratio
- Approximately 15% water by weight
- ~2.3 oz water per 1 lb of product
Mixing Instructions
- Add clean potable water into mixing container
- Slowly add powder while mixing
- Mix to smooth, flowable consistency
- Avoid overwatering (reduces strength)
Placement
- Pour directly into prepared hole or void
- Ensure full encapsulation of anchor bolt or rod
- Finish slightly above surface to prevent water pooling
Surface Preparation
Proper preparation is critical for performance:
- Concrete must be fully cured (minimum 28 days)
- Remove all dust, debris, oil, or laitance
- Pre-dampen hole (SSD conditionsaturated surface dry)
- Do not leave standing water in anchor hole
- Use proper washer sizing for bolt load distribution
