Applications & Uses
- Applications
- General Uses & Applications
- Bonding hardened concrete to hardened concrete
- Bonding fresh concrete to hardened concrete and steel
- Coating and sealing interior or exterior slabs
- Durable, chemical resistant industrial coating and adhesive
- Mortar repair for concrete and spalls when mixed with dried silica sand or aggregate
- Gravity feed medium to large horizontal cracks
- Installation and Coverage
In order to achieve maximum results, proper installation is imperative. Bonding Agent - 1 gallon covers approximately 80 ft2 (7.4 m2 ) at a thickness of 20 mils. Adhesive - 1 gallon yields 231 in3 (3.8 L). Grout/ Mortar Repair - 1 gallon mixed with one equal part dried silica sand yields approximately 450 in3 (7.4 L) of grout. NOTE: Coverage may vary slightly according to surface temperature, surface texture and sand gradation.
- Clean Up
Always wear appropriate protective equipment such as safety glasses and gloves. Clean uncured materials from tools and equipment with mild solvent. Cured material can only be removed mechanically.
- Limitations and Warnings
- Do not thin with solvents, as this may affect cure.
- Not recommended for any anchoring and doweling application where there may be a sustained tensile load, including overhead applications.
