My husband who is a handyman of incredible skill, has a few tasks that he loathes. Painting is one of them. Grouting is another. We have added tile accents to a few areas of our house, and the grouting has fallen to me. I am a cake decorator and hit upon a fantastic solution that solved having to “work” the grout into the cracks of the tiles, pastry bags and writing tips! Cuts the job by more than half. Obviously this won’t work for all tile jobs, because there has to be a large enough space in between the tiles to get the icing tip into the space, but with the tips you can make sure that your grout cracks are absolutely full of grout, no air bubbles.
