I'm in the process of selling our home and just put down vinyl tile on bathroom floor but spaced tiles 1/4 inch apart. After reading the vinyl tile grout container, it is for spaces 1/16" - 1/8". Now I have 3 questions: 1) If I apply the vinyl tile grout as is (1/4 spacing), will the grout crack? (I'm assuming so as the product says for spaces up to 1/8 only) 2) Could I apply sanded (isomeric) caulk in the grout line instead? What problems can I run into if I use the sanded calk? 3) Is there a vinyl flooring grout to apply in 1/4" spacing?
