Is it ok to mix sanded with unsanded grout provided the grout is from the same manufacturer? I'm using Home Depots Polyblend product.

  • Why do you feel that grout shrinkage will be a problem? This is normally unnecessary (and could be problematic) for wall tiles with grout joints <= 1/8". Oct 13, 2018 at 18:20
  • I tested on scrap tile and found some shrinkage and separation, not much but it was noticeable.
