Product Description: AQUAFIN CRACK SEALING TAPE is an elastomeric, highly tear resistant, waterproof tape, comprised of a polyester fabric with a PVC elastomer coating. Typical Applications: • For sealing cracks in concrete prior to the application of AQUAFIN2K/M system in waterproofing applications. Advantages: • Quick and easy installation • Waterproof • Permanently flexible • UV stable/resistant • Highly resistant against oil, grease and solvents • Excellent decomposition resistance (microbes) Substrate Preparation: The substrate must be sound, clean, and free from voids or ridges, bug holes, honey combs, and open pored (like medium grit sand paper). • Remove bond breakers, such as oil, grease, dirt, loose particles, remains of form oils, water repellents, rust or other coatings by high pressure waterblasting (>5000 psi (34.5 MPa)) or wet or dry sandblasting. • Prepare surfaces by mechanical means to obtain a surface profile of CSP 3 - CSP 5 per ICRI Guideline No. 310.2-R-2013. • Repair holes, defects, irregular surfaces, weak mortar joints, etc. with MORTAR-V/O or MORTAR-LN. • Close large open pores and joint recesses of CMU blocks and joint unevenness in brick walls with MORTAR-V/O or MORTAR LN. • Dampen substrate with clean water to saturated surface dry (SSD) condition, with no standing surface water. • Static cracks should be routed out in a “u” shaped configuration, approximately 3/4” (20 mm) wide x 1” (25 mm) deep and filled with a suitable concrete repair product, such as AQUAFIN QUICK PATCH, MORTAR V/O , MORTAR-40 CI or MORTAR-LN. • Dynamic (moving cracks) should be filled with a suitable urethane sealant or chemical grout. Pre-soak the area of concrete to be taped with clean water to a saturated surface dry (SSD) condition, with no standing surface water.

All above values theoretical. Variations may apply due to substrate conditions. Thickness per application or lift, up to 50 mils (1.25 mm).
Product Application: • AQUAFIN CRACK SEALING TAPE is bonded to concrete with AQUAFIN-2K/M flexible cementitious coating. • Refer to the AQUAFIN-2K/M Technical Data Sheet for mixing instructions. • Apply a coat of AQUAFIN-2K/M, extending a minimum of 3/4” (20mm) beyond either side of tape. • Immediately embed AQUAFIN CRACK SEALING TAPE into the 2K/M uniformly, leaving no wrinkles, using a trowel or similar. • To connect tapes, after installing the first tape, slightly overlap a second tape a minimum of ½” (12mm) using AQUAFIN-2K/M. • Allow 3 to 4 hours to cure before applying the first coat of AQUAFIN 2K/M system. Limitations: Before applying the final coat of AQUAFIN 2K/M, inspect the areas sealed with the AQUAFIN CRACK SEALING TAPE. For aesthetic reasons, a light

AQUAFIN® CRACK SEALING TAPE sanding or grinding of the 2K/M used to adhere the AQUAFIN CRACK SEALING TAPE may be necessary to “smooth” out the area.
Health & Safety: Refer to SDS.
Cracks will often telegraph through any overlay material. While crack repair is recommended before application of AQUAFIN 2K/M, AQUAFIN does not warrant that cracks will not reappear, even when following established repair techniques.
