I took a chance and bought the fix tape for our cracked bath. We simply cleaned and dried the surface and sticked the fix tape over the crack. The bath is so badly cracked that all the water runs through. Now the problem is solved until we can fit a new bathroom. We are heavy people and steps on the crack when we get into the bath. The fix tape simply stretch with the weight and then shrinks back. Thanks alot for the product that solves temporary promblems.
