GOOP is the brand they have several kinds you get it at Home Depot or Lowe's.I squeezed a tad out of the tube and dragged a toothpick over it to apply to the marble and ball. Let them sit 4 minures before putting them together.. when you put the 2 pieces together if it oozes too much just use a q-tip to drag it off.
you do have to seal it with grout or cement sealer. the stuff I used was grout sealer but may try something else....Several kindsThis message has been edited. Last edited by: 7575EH,
