PC-Concrete Epoxy Adhesive Paste for Anchoring and Crack Repair

In this review the PC-Concrete epoxy adhesive paste is evaluated for contractors and serious DIYers who need a high-strength, moisture-tolerant anchoring and crack repair solution. The bottom line: it delivers a durable, paintable bond for anchoring threaded rods, bolts and dowels and for filling cracks in concrete and masonry, with a convenient two-part cartridge system suited to damp or vertical applications. Work time and cure speed make it practical for typical jobsite use, and it meets ASTM C881-99 for performance expectations.

Key Features

• Two-part epoxy paste: Provides a high-strength bond that holds threaded anchors and repairs concrete after it fully cures, resisting expansion and contraction.
• High-tack, moisture-resistant formula: Allows application on damp surfaces and in vertical locations without sagging or running, expanding use cases on site.
• Cartridge dispensing: Designed for use with a 600ml dual rod gun for consistent mixing and placement, reducing waste and ensuring the correct resin-to-hardener ratio.
• Practical working and cure times: Offers about 20 minutes of work time and reaches handling cure in roughly 4 hours at 75 degrees F, balancing time to adjust with reasonable jobsite throughput.
• Wide service temperature range: Rated to perform from -20 to 115 degrees F in service and can be applied between 35 and 115 degrees F, suitable for indoor and outdoor tasks.
• Paintable and machinable finish: After full cure the paste can be painted, stained or machined and is nonconductive and nontoxic once cured for finish work.

Who It's For

This product is aimed at trade professionals, structural contractors and experienced DIYers who need a dependable epoxy for anchoring and concrete repair where moisture or vertical application is a concern. It is particularly useful for anchoring threaded rods or bolts into concrete, grout-filled block and unreinforced masonry where a high-strength, permanent bond is required.

Those who should look elsewhere include users needing very fast set times for immediate heavy loading or those without access to a compatible 600ml dual rod gun, since the cartridge requires the proper dispenser for correct mixing and application.

Pros & Cons

Pros

• High-strength bond suitable for anchoring and structural repairs, described by users as very durable.
• Moisture-resistant paste that can be applied to damp surfaces and vertical areas without sagging.
• Paintable and machinable after cure, allowing finished surfaces to be matched or treated.

Cons

• Requires a #993002 600ml dual rod gun for proper dispensing, so additional equipment may be needed.
• Some users reported minor dispensing or component leakage issues with the white component, so careful handling is advised.
