Hi, i have gotten my home tiles from hafary. At the showroom, we saw an italian tile that is light grey in color. However after my id install the tile. The tiles have huge variation in color and lines. Some are light grey, some are dark grey, some are yellowish. Theres some even with rust spots on the tiles. I got my id to check with the hafary representative. They claimed that the tiles i gotten are meant to create slate effects. The rust are iron materials that they used to create the stoney texture. Can i check are the tiles meant to be like that or have hafary gave us defective tiles? The other thing that puzzles me is why didn hafary saleperson advise us when we chose the tile? We just want homogenous light grey tiles. They could have advise that the tiles will hAve slate effects. We definitely wouldn have gotten them. Appreciate your advice.
