What are the most common grout problems, and how do I avoid them?
Poor installation technique can lead to many types of problems (e.g. shading, blotching, shrinkage cracks, powdering and efflorescence). The best way to avoid these problems is to use LATICRETE® SpectraLOCK™ PRO Grout or LATAPOXY® SP-100. For more information on how to prevent grout problems, check out TDS201.
