Good Morning all:<br><br>A hotel management company that I work for had me inspect their ceramic tile flooring. They say that no matter how they clean it dark spots return within a couple of days. Weather is not a factor, happens throughout the year. I believe that some thing in the setting is bleeding through. I have attached pics and you will notice that in #039, there is a shadow of a trowel line. this also appears on several other tiles. The other pics demonstrate the darkness that reappears every time. the install is about 5 years old in downtown Denver. I am going to go back with a moisture meter and have a tile in my shop which I am trying to replicate their experience with. Any suggestions would be helpful.<br>
<br>Thanks in advance<br clear="all"><br>-- <br>Sincerely:<br><br>Don Semi<br>Certified Stone and Tile Inspector<br><a target="_top" href="http://www.srsdenver.com" target="_blank">www.srsdenver.com</a><br><a target="_top" href="mailto:srsdenver@gmail.com" target="_blank">srsdenver@gmail.com</a><br>
