Having let first silicone bead cure for over 1.5 days, I have just applied bead 2. It looks great except the concave tunnel is still slightly behind the plumb line of the wall and there is only a very thin coating on the tile and tub edges because the silicone had to go so far into the cavity. Do I dare add a 3rd bead in 1 1/2 to 2 days? Common sense would seem to indicate that water coming down the tile should hit part of the moulded bead? Thanks.
