I put tiled mosaic paw glass (I think). My problem: is this normal? I am laying the joints and on the part laid yesterday on wall mosaic the joints are pierced with a small net hole at each corner of each small tile...? it's in a bathroom... What did I miss?
The appearance of "holes" at each angle of tile can have two causes, often related: a seal too liquid associated with a reduced joint width. The width of the joint being defined by the laying of the tiles, it is then necessary to achieve a drier mixture, but nevertheless sufficiently creamy to properly fill the location provided for the seal.
