Hello all,
I have a porcelain tile floor that runs through a large kitchen, dining area, hallway and bathroom. The subflooring is thick enough with no noticeable motion. The tiles appear very secure. The floor was laid about 6 months ago. There are now hair line cracks in the grout throughout the project. They are not in one particular area. They run mostly from the corners of the tile. The tiler was surprised by the cracking grout and he plans on removing the grout to replace it. He said he wants to put in a flexible grout. What type of flexible grout do you recommend?
