DAY1 is a colloidal silica finishing aid that lubricates the surface for faster, easier finishing. DAY1 extends workable time under adverse conditions such as high wind, heat, or low humidity. DAY1 eliminates the need to add water to the surface, which can be detrimental to the surface performance of the slab. It can also be used to help finish shake-on hardeners in low bleedwater environments. Concrete with high cement, air, silica fume, or silica flower are easier to finish when DAY1 is applied.
Colloidal silica is at the heart of DAY1 technology. The amorphous silica reacts during the hydration of concrete to produce more cementitious material, translating into higher density and improved surface performance.
DAY1, applied during finishing, provides a number of long-term of benefits to cured concrete. DAY1 reduces surface evaporation, mitigating and reducing ASR, slab curling, and differential shrinkage. DAY1 also has densification properties to prevent dusting and reduces efflorescence in colored and standard concrete.

Coverage Rates
DAY1 will yield different results based on the jobsite conditions and usage demands. Before floating or troweling, test DAY1 on a sample section to determine appropriate application rate and technique before applying to the entire project area.Use these coverage rates as a starting point to determine the necessary application rate. Coverages are based on a mixed ready-to-use (RTU) gallon of DAY1. DAY1 can be applied at multiple stages during finishing.
