PC Products 72561 PC-Concrete Two-Part Epoxy Adhesive Paste for Anchoring and Crack Repair, 8.6 oz Cartridge, Gray

PC Products PC-Concrete is a concrete epoxy adhesive paste for homeowners and repair professionals who need to address cracks or anchor threaded rods, bolts, and dowels into masonry. Its main appeal is versatility: the same two-part formula is intended for concrete crack repair and anchoring applications in concrete, grout-filled block, and unreinforced masonry. That makes it worth considering when a project involves either damaged concrete or securing an anchoring component, rather than a general-purpose adhesive job.

The high-tack paste is designed for vertical applications and can be used in damp environments because it resists moisture. Those qualities matter when the repair area is not horizontal or conditions are not completely dry. The product is also intended for indoor and outdoor use, giving it flexibility across different project locations. Its stated application temperature range is 35 to 115 degrees F, while its service temperature range is minus 20 to plus 115 degrees F. These are separate considerations: one concerns application conditions, and the other concerns temperatures during service.

Timing is another important part of the decision. At 75 degrees F, PC-Concrete provides 20 minutes of work time and a cure time of 4 hours. The work period gives the user a defined window for placing and positioning the material, while the stated cure time helps with planning around the repair. Because these figures are tied to a particular temperature, the conditions of the job deserve attention rather than assuming the same timing applies in every environment.

The formula is intended to bond with cleaned concrete surfaces and accommodate the expansion and contraction of concrete. It also meets ASTM C881-99, a useful specification to recognize when comparing concrete epoxy products. Still, the practical fit depends on matching the product to the actual repair or anchoring task, the substrate, and the working conditions. The 8.6 oz cartridge is a defined quantity, so project size should be considered before choosing it. Its specialized purpose is a strength for suitable masonry work, but it is not a reason to treat it as an all-purpose household adhesive.

Verdict: This concrete epoxy adhesive is a strong candidate for shoppers repairing concrete cracks or anchoring rods, bolts, and dowels in the listed masonry materials. Choose it if the application conditions, work window, and cartridge quantity fit your project; consider a different repair product if your task falls outside those uses or requires a different working time.

• Product type: Two-part epoxy adhesive paste
• Cartridge size: 8.6 oz
• Color: Gray
• Work time: 20 minutes
• Cure time: 4 hours at 75 degrees F
• Application temperature: 35 to 115 degrees F

• Intended locations: Indoor and outdoor
• Listed substrates: Concrete, grout-filled block, and unreinforced masonry

A great fit if you:

• You need one product for concrete crack repair and anchoring threaded rods, bolts, or dowels in masonry.
• Your project involves a vertical concrete surface where a high-tack paste is useful.
• You need an adhesive for an indoor or outdoor repair and can work within its application temperature range.
• You are repairing cleaned concrete and want a two-part epoxy formulated for concrete movement.

Consider something else if you:

• Your project involves materials outside the listed substrates, making a material-specific adhesive a better match.
• You need a product with a longer working window or a different application temperature range, so compare alternatives against those requirements.

Confirm on the listing:

• Check whether the 8.6 oz cartridge quantity is appropriate for the cracks or anchoring points you intend to address.
• Confirm that your substrate is concrete, grout-filled block, or unreinforced masonry, and identify whether the job involves crack repair or anchoring.
• Check whether the package includes any dispensing equipment or other items you need, rather than assuming accessories are included.
• Compare your expected working conditions with the application range of 35 to 115 degrees F and the service range of minus 20 to plus 115 degrees F.

How to compare your options: Start with the intended repair, compatible substrate, and whether the material must be applied vertically or in a damp environment. Then compare work time, cure time, temperature ranges, cartridge quantity, and any stated standards. PC-Concrete combines crack repair and anchoring uses, with 20 minutes of work time and a 4-hour cure time at 75 degrees F. Those details help establish whether it fits the job's scope and schedule.

Begin by identifying the exact job. Crack filling and anchoring are both intended uses, but deciding which one applies helps you assess the placement and amount of material needed. Check that the surface is cleaned, since the product is formulated to bond with cleaned concrete.

Review the working conditions before starting. Keep the application temperature within the stated range of 35 to 115 degrees F, and consider the separate service temperature range when evaluating the finished repair's environment. Its suitability for damp environments does not remove the need to consider the actual conditions of your project.

Plan the work around the stated 20-minute work time and 4-hour cure time at 75 degrees F. Have the repair or anchoring task organized before applying the two-part paste, so the available working window is used deliberately. Do not automatically assume those timing figures apply unchanged at other temperatures.

For future reference, keep the product instructions with your project notes if available. Record where the material was used and whether the job involved crack repair or anchoring. Follow the manufacturer's directions for preparation, application, curing, and storage rather than improvising a method based on a different adhesive.
