hoping this forum can help me! I just had an inground spa constructed and chose stonescapes aqua white pebble with glass. Apparently the glass was “sprinkled” on top during the application process…not mixed in the actual bag. I imagine they do this to save money? Is this common practice? I ask because the glass beads are not spread uniform throughout and I can basically tell it was done by hand because there are some areas that are not blended well where i see clumps of the glass. My pool company is telling me that is how the glass is typically applied….however i am skeptical and feel like it should have been mixed in the bag first. Please advise!
