  • Weak acid based concrete stain
    Patent number: 8460399
    Abstract: The present invention provides compositions and methods which are adapted to impart color to concrete or mineral substrate surfaces. Specifically, the present invention relates to a composition and methods adapted to treat concrete surfaces which have the advantage of using a non-corrosive acid-based solution.
    Type: Grant
    Filed: May 10, 2007
    Date of Patent: June 11, 2013
    Assignee: Valspar Corporation
    Inventors: Sanford Lee Hertz, Ed Daraskevich, William W. Tao, Jason J. Netherton, Matthew S. Gebhard
  • CONCRETE COLORING COMPOSITIONS AND METHODS
    Publication number: 20120247372
    Abstract: The present invention provides acidic compositions and methods that are adapted to impart color to cementitious or mineral substrate surfaces. Specifically, the present invention relates to acidic compositions and methods adapted to treat cementitious or mineral substrate surfaces that have the advantage of using a less corrosive acid-based solution. The acidic composition incorporates species including a weak base in equilibrium with a conjugate acid. The presence of such species moderates the corrosive behavior of the acid while still allowing excellent coloring action to occur.
    Type: Application
