Colloidal Silica - Ron Blank & Associates, Inc.

Colloidal Silica Overlay SystemsMany cementitious overlays today are self-leveling systems madewith specialty cements, as opposed to ordinary portland cement.These systems allow for minimal thickness buildup. These modifiedcement products have less residual lime available with which toreact.These systems also exhibit lower abrasion resistance due to lowaggregate content and benefit immensely from fortification withsilica.However, with less CalciumHydroxide available to them,silicate densifiers have such alimited opportunity to react thatthey are, for the most part,ineffective.
