|I have a customer with a large tiled shower including the floor.
There is something seeping from the grout joints in the floor, but not in the walls, and it is hard and somewhat takes on the color of the grout and tile.
Neither the customer nor I have any knowledge of the showers history other than it has been there for years.
Is it possible to submit an image with this question and if so, what are the file size and extension types that can be used.
I think that the image would help much more than just a description.
