Are Liquid Silicate Surface Hardeners Effective?

Liquid Silicate Hardener/Densifier Debate: Two flooring experts debate the effectiveness of liquid silicate surface hardener/densifiers. In the January 2014 issue of Concrete Construction, George Garber described his experience with floors treated with liquid hardeners and concluded that he had seen little benefit in terms of wear resistance. Peter Wagner refutes some of that testing and concludes that a hardener/densifiers can be effective in the right situation.
