[Existing Specialized] Effective even with neutralized concrete (solving issues related to reactive types). Please also utilize it for surface coating and substrate modification in cross-section repair.
L-OSMO Solidification Type KK" is a solidification-type lithium silicate surface impregnation material that contributes to the preventive maintenance and longevity of existing concrete structures. It is effective for concrete surfaces that have become neutralized, where conventional silicate-based surface impregnation materials are not applicable. By densifying the concrete surface and sealing cracks of 0.2mm or less, it suppresses the progression of deterioration and reduces lifecycle costs. There is no change in appearance after application, and any deformation of the concrete can be visually confirmed. Reapplication is easy, and it can be used in conjunction with other methods. Preventive maintenance and longevity measures can be achieved on a low budget. No special qualifications are required, and it allows for quick and easy application. By modifying the base concrete with "L-OSMO Solidification Type KK," and then applying surface coating materials and cross-sectional repair materials, it is also effective for extending the lifespan by providing double protection to the concrete surface and its exterior (both inside and outside). It is also effective in areas with low applicability of silane-based surface impregnation materials, such as water accumulation points and cracked areas. *Due to the increase in the product lineup in 2023, the name has changed from "OSMO-KK" to "L-OSMO Solidification Type KK.
