Properties
LANKO 222 K11 CONCENTRATE is a cement-sand-based waterproofing material that is mixed with water and applied by brush or trowel onto concrete or plastered surfaces to prevent water leakage. Once dry, it forms a hard surface finish. It is suitable for structural applications, foundations, and basements requiring soil backfilling. The product is non-toxic and can be used in water storage tanks.
Applications
Interior and exterior applications, such as:
Interior surfaces of water tanks, reservoirs, and drainage channels
Interior and exterior basement walls
Around foundations

Application Recommendations
Surface Preparation
The substrate must be sound, clean, and free from dust, oil, paint, dirt, loose plaster, or gypsum. Remove all loose or delaminated materials.
Holes, voids, cracks, and damaged structural areas must be properly repaired. LANKO 731 LANKOREP STRUCTURE may be used for these repairs.
Sharp edges and corners, such as floor-to-wall joints, room corners, and wall corners, must be rounded off or provided with a fillet to eliminate sharp angles.
Pre-wet the substrate to ensure it is damp before application. There should be no standing water on the surface during application.
