Underwater Magic (White)

It works as an underwater glue . I fixed a few tiles in my swimming pool which had come loose and also repaired some grout again under water (used my scuba gear). They only appear to have brilliant white shame there is not some choice of colours as brilliant white is not used in most swimming pools so repaired grout does stand out. The fixed tiles have remained solid (few months) and the grout stayed in place. Can be a bit messy to use sticks to everything but a soft scrubber takes excess off the glazed tiles.
