Lythic began with the discovery of reactive Colloidal Silica as a new way to add strength and durability to concrete floors, by two veterans of concrete polishing in 2004. Intimately familiar with the advantages of exposed concrete floors, both polished and unpolished, they were also acutely aware of the drawbacks of the existing chemistry available. They recognized the benefits of this advance in concrete densification chemistry as they used it for their own projects. From this direct experience new products and processes were developed and have expanded possibilities for concrete floor finishes. Lythic is unique in providing expertise in product and processes that are advancing concrete flooring beyond the costs, risks, and limitations of polished concrete floors.

          A.Application Polished concrete gloss film forming concrete protector, colloidal silica sealer:
          1.Apply per manufacturer's published recommendations to clean, dry slab at the completion of mechanically polishing the slab surface.
          2.Lightly wet a clean microfiber mop or cotton pad with protective treatment and wring out excess, leaving the pad damp.

          3.Lightly wet a lint free short nap paint roller with interior high performance sealer and remove excess, leaving primed paint roller.
          4.Roll out interior high performance sealer using minimal downward force. Evenly roll the interior high performance sealer without leaving overlap lines at an estimated coverage rate of 1000 to 1500 square feet per gallon. Working from one control joint to another.
          5.Maintain a thin, even coating and wet edge. Do not over apply.
          6.Allow 4-6 hours before of dry time before a second application is applied (Only re-coat if needed) Repeat steps 1 through 4 for re-coat application.
