Q. How do I measure each component to mix equal amounts?
A. Just pour a small amount of Part A onto a piece of cardboard and then an equal amount of Part B next to the Part A. By sight, the two poured amounts should be the same size.
Q. How long does it take for the Adhesive Part A and Part B mixture to start to set and how long does it take to cure?
A. Once Part A and Part B are mixed, the set time is approximately 2 to 3 minutes, which is dependent on temperature. The cure time can take up to 3 hours.
Q. How do I know if the Adhesive has cured?
A. The Adhesive Part A and Part B are cured when the mixture has hardened to the touch. An excellent way to test this is by poking the spatula into the paste, and no marks are left behind.
Q. Why do I need to patch the crack on the outside surface above grade?
A. During the crack injection process, the injection material penetrates the entire thickness of the foundation crack to ensure a complete seal. The compacted dirt on the exterior of the foundation crack will act as a wall barrier during the injection process. So as the injection material penetrates the foundation wall crack above grade level, there is nothing on the inside to hold in the resin from seeping through. Therefore, patching the crack above the grade level with the Adhesive Part A and Part B will act as a wall barrier to allow the injection to penetrate the entire wall thickness all the way up the foundation wall, entirely.
Q. What do I do if the injection resin seeps out through pinholes in the hardened Adhesive Part A and Part B?
A. Stop the injection and re-apply Adhesive Part A and Part B mixture to cover these pin hole areas.
Q. Can I apply additional Adhesive Part A and Part B over the existing cured Adhesive Part A and Part B to patch any existing pin holes?
A. Yes, the new mixture will bond to the existing cured adhesive patch.
Q. How long should I wait for the Adhesive Part A and Part B to set before re-injecting the injection resin again?
A. The Adhesive Part A and Part B needs to be hardened to the touch before re-injecting.
Q. Can the hardened Adhesive Part A and Part B be removed?
A. The cured Adhesive Part A and Part B can be removed by using a heat gun to reverse the cured material to a soft material and removed with a metal scraper. Wait at least 48 hours after the repair to remove the adhesive to ensure the injection material has wholly cured in the wall.
Q. Should I be concerned when the surface of the Adhesive Part A and Part B patch over the crack has cracked?
A. The Adhesive Part A and Part B is an epoxy and is inflexible when cured. As the foundation crack expands and contracts during thermocycles, cracks will eventually appear in the surface paste. Should this happen, there is no concern about the crack repair since the patch was only used as a temporary wall barrier during the crack injection process.
