Less strain on the shoulders, maintaining pressure with the trowel for speed! Achieving excellent rapid hardening and workability.
Magical SP-3 is the ultimate labor-saving repair material that demonstrates excellent workability, which could not be achieved with a single material in plastering work, thanks to special viscosity adjustment that enhances trowel spread and release, as well as its lightweight nature. It places less burden on the shoulders, allowing for stable work quality with a single coat thickness of 5 to 30 mm while maintaining trowel pressure during ceiling and wall construction. It has excellent rapid hardening properties, reaching practical strength in a short time, and can secure over 30 minutes of usable time even in a 30°C environment. 【Features】 - Outstanding workability - Rapid hardening with a long usable time - Excellent various performances - Compliant with the NEXCO Construction Management Guidelines "Performance Verification Items for Section Repair Using Plastering Method" For more details, please contact us or download the catalog.

Company information
Nihon Jikkou is a core company of a comprehensive engineering group that contributes to society through the production and sale of various related materials, starting with concrete anti-corrosion construction. Japan is now entering an era of high prevalence of social infrastructure such as water supply and sewage systems, with a vast number of concrete facilities being stockpiled. However, as these facilities age and deteriorate, it has become an urgent issue to systematically and effectively implement repair and maintenance measures to sustain them in the future. Nihon Jikkou and its group companies address these challenges by proposing optimal deterioration prevention measures based on environmental factors and facility characteristics, along with excellent construction techniques, thereby meeting all maintenance and management needs for concrete structures.
