Colloidal Silica DensifiersColloidal silica densifiers produce no excess mineral salts (whichdiscolor concrete) and no “whiting,” even if over-applied.Due to a smaller silica particle size, reactive colloidal silica has morereactive sites on the molecule than silicates and, therefore, formschemical bonds more readily. It fills the pore structure moreconsistently, making an extremely hard, dense floor surface that hasincreased wear resistance to foot and fork lift traffic.Damaged concrete that is soft and dusting can be improved withapplications of colloidal silica, enabling the floor to take a polish.
