Advice for re-grouting floors?
Is it possible to "add" grout on top existing grout? Or does one need to remove the grout to redo it? It is unsanded grout that was done very recently and unsealed. Unfortunately, the grout sank or shrank and has now become grout troughs. The lines are 1/4 inch on a large format mosaic floor. Thanks in advance!

Hi Laurie, as long as the pre existing grout is in good shape I don't see why you couldn't go right over it.
Hello, if the grout is unsealed it should adhere to new grout that you put on it.
