Press the grout into the crack. Smooth the surface with your finger or a small cloth. Wipe excess grout from the wall and tub with an old cloth or sponge before it gets dry. Let the grout dry well before anyone uses the tub. (The grout will last much longer and resist mildew better if it is sealed.) To seal paint the grout with a grout sealer after it has dried.
