We placed our tile in mortar using the recommended tool and it squished up higher than intended and dried in the grooves of the tile sides because I ended up in the ER at the time it was supposed to be cleaned out. We have been trying to scrape mortar out of the mosaic tiles but it is extremely difficult. We thought about options, ie. Scraping mortar, ( how best to do so, I don't know. The tiles are as small as 3/4 inch, a daunting task), using a tile sealing caulk in place of grout since there is not much grout, tearing the whole thing out and starting over(the least desirable. Suggestions?
