Hello Dave,
Thank you for responding. The type of grout used is a "sanded grout; polymer-fortified; mold- and abrasion-resistant." When the
tile was initially layed and even after it was grouted and dried, it was SO beautiful. Then one week later it was "sealed" with "DuPont StoneTech BulletProof Sealer- advanced penetrating microbond protection, water-based, for natural stone" solution and it was then that it became hazey...and I am very sad. Is there something that I can do to reverse this? I wish I would have educated myself about "sealing" --as now after reading several threads from the "experienced guys who know and understand natural stone"--I never would have allowed the travertine to be "sealed". Shanti.
