SURFACE PREPARATION
Cut or notch out the crack, joint, or void to a minimum dimension of ¾"x ¾". To ensure proper mechanical lock, the bottom of the newly notched opening should be wider than the top. (Avoid "V" type notches or cuts.)
Prepare surface in accordance with ICRI Technical Guide No. 03730. Substrate must be structurally sound and free of grease, oil, dirt, or any other contaminants that can adversely affect the bond. If the crack to be repaired is dry at the time of application, substrate must be dust free, then saturated, surface dry (SSD).

MIXING AND PLACEMENT
Mix MEADOW-PLUG with enough potable water to form a thick putty consistency (approximately a 3:1 ratio by volume). Do not mix more MEADOW-PLUG than can be placed in one minute. Force MEADOW-PLUG directly into prepared crack and hold in place, maintaining pressure until material hardens. Avoid overworking the material. Just prior to final set, MEADOW-PLUG may be "shaved" to match the profile of the area surrounding the patch. If repairing a dry crack, wet cure immediately for at least fifteen minutes or until set is fully achieved. Do not use on any moving joints.
