Sealing grout on a glass tile mosaic backsplash?
First time homeowner looking for some advice on how to properly seal my new kitchen backsplash. I have a glass tile mosaic that was installed about 4 months ago, and have not yet sealed the grout. Can anyone recommend a product that is safe to use with glass tile mosaic. Some people say some grout sealers may cause the glass tile to become hazy. Also, is it necessary to seal the grout? will any water splashing on the grout change cause it to stain if i dont?
