Day1 is a finishing aid that lubricates the surface for faster, easier finishing. Day1 can also extend workable time by 15 to 30 minutes, even 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. Day1 is a safety net, giving finishers more time on the slab.
Day1, applied during finishing, provides a number long term of benefits to cured concrete, as well. Day1 has been shown to reduce surface evaporation, mitigating and reducing slab curling and differential shrinkage. Day1 also has densification properties and reduces efflorescence in colored and standard concrete.
"DAY1 is a colloidal silica finishing aid. Using a special formulation of silica nano-particles, DAY1 forms additional cement paste without weakening the surface. This is what differentiates DAY1 from other common so-called finishing aids." - Retrevied on 9/26/17 from http://www.brickform.com/Blog/Posts/2056/Other-Products/2016/8/Beat-the-Heat-with-One-Simple-Product/
