PC Products 72561 PC-Concrete Two-Part Epoxy Adhesive Paste
PC Products 72561 PC-Concrete is a two-part epoxy adhesive paste designed for concrete crack repair and anchoring threaded rods, bolts, and dowels. Its high-tack formula resists moisture, enabling use in damp environments and on vertical surfaces. Suitable for indoor and outdoor applications, it prints a broad temperature range: application from 35 to 115 degrees Fahrenheit and service from -20 to 115 degrees Fahrenheit. This makes it versatile for garages, basements, and exterior concrete work where moisture is a consideration.
DCP Quickmast Anchor E Concrete Anchoring Epoxy
DCP Quickmast Anchor E is a two-part pure epoxy system designed for anchoring rebar, rods, and fixtures into concrete. It offers an extended working time of 3 to 20 minutes, allowing careful placement and adjustments before curing begins. The system cures quickly to full load capacity within 3 to 24 hours, supporting efficient project timelines on various construction sites while delivering strong bonding for both light and heavy-duty installations.
PC Products PC-Concrete Epoxy Adhesive Paste for Anchoring and Crack Repair
This PC-Concrete epoxy paste comes as two-part, packaged in 102 oz across two pails, making it suitable for larger projects. It excels at filling cracks and anchoring threaded rods, bolts, and dowels into concrete, grout-filled blocks, and unreinforced masonry. The high-tack paste resists moisture, enabling use in damp environments and vertical applications. With an application temperature range of 35 to 115 degrees Fahrenheit and a service range from -20 to 115 degrees Fahrenheit, it adapts to many job sites and climates.
DCP Quickmast AE15 Concrete Epoxy for Rebar and Rods
Quickmast AE15 is a two-part epoxy- acrylate anchor system designed for concrete anchoring across a range of loads. It supports securing rebar and threaded rods with a working time of 4 to 10 minutes and a rapid cure, achieving full load capacity in 40 to 145 minutes depending on base material temperature. The kit includes a 10.1 fl oz cartridge and nozzles for standard caulking gun use, making it convenient for field and shop settings alike.
FixMaster Multi Purpose 2-Part Pure Epoxy 9.5oz
FixMaster Multi Purpose 2-Part Pure Epoxy offers strong bonding for anchoring and crack repair on concrete, masonry, and other building materials. It is ICC approved and conforms to ASTM C881 Type IV, Grade 3, Class A, B, C. The product is designed for high structural loads and durability, suitable for interior and exterior use on horizontal, vertical, and overhead applications. An extra nozzle is included for reuse on a second job, emphasizing value on multi-project sites.
PC Products PC-Masonry Epoxy Adhesive Paste
PC-Masonry Epoxy Adhesive Paste is a two-part repair epoxy tailored for masonry. It replaces missing concrete or fills cracks in deteriorating masonry and resists moisture on both wet and dry surfaces. Suitable for indoor and outdoor use, it accepts a broad temperature range: 35 to 115 degrees Fahrenheit in application and -20 to 200 degrees Fahrenheit in service, making it a flexible option for brick, block, and stone repairs.
Gorilla 2 Part Epoxy, Clear Epoxy
Gorilla 2 Part Epoxy provides a clear, strong bond suitable for household and automotive repairs. It sets in about five minutes, giving time for repositioning before the product cures. While versatile for gap filling and bonding vertical surfaces, it is a general-purpose epoxy rather than a concrete-specific system, so users should assess substrate compatibility for structural anchoring or masonry repairs.
Buying Guide: Key Purchase Considerations
- Bond strength and load capacity: For structural anchors and heavy-duty rebar, prioritize products marketed for high-strength anchoring and concrete adhesion, as these often provide higher shear and tension values.
- Moisture resistance: In damp or wet environments, choose epoxy formulations with moisture resistance to prevent bond degradation and hydrostatic concerns.
- Working time and cure speed: Consider project pace. Longer working times help with precise placement, while rapid cures accelerate project completion in time-sensitive jobs.
- Temperature tolerance: Applications in unheated spaces or outside require epoxies with broad application and service temperature ranges to avoid premature set or reduced performance.
- Volume and packaging: For large repairs, larger pails or dual-cartridge systems reduce downtime and cartridge waste. Verify compatibility with standard caulking guns if necessary.
- Compatibility with substrates: While designed for concrete, some products also work with masonry, grout-filled blocks, or unreinforced masonry. Confirm substrate compatibility for your project.
- Code and standards: ICC and ASTM-classified products meet recognized building standards, which may influence long-term performance and insurance considerations.
- Cost versus reuse: Some kits include extra nozzles or additional components, delivering better value across multiple jobs or ongoing maintenance projects.
