If you started your first row of tile butted against the top of the tub, then run a bead of Caulk around it. If there is a gap between the top of the tub and the tile on the wall, apply a thin layer of grout, let it dry overnight, then apply the bead of caulking over the top of the grout, (just around the tub).
PS, The grout and the caulk will mildew unless the water is always dried off after every shower, (assuming it is a shower/bathtub combo). But not to worry, plain old clorox bleach will remove the mildew from grout and caulk. I usually just put some in a spray bottle, open the window, turn on the exhaust fan, put a mask on, spray the mildew down and get the heck out of there quick as possible because the bleach makes me sick and it is not good to inhale it. Then close the door for a couple hours. Then go back in and rinse it down with plain water.
PSS, It is only necessary to allow the adhesive to dry for 24 hours before grouting. :) You are going to use Unsanded grout, right?
You can also pick up a grout sealer.
If you have any questions on the grouting process, leave me a message in the comment box.
PSSS, Your grout will not melt. LOL!
