I would buy a caulk gun. They are cheap. And a big tube that fits in it. It's just a lot easier on your hands then squeezing out the tube, though you can do it with a tube.

Acrylic has been used in wet areas (indoors and out) for decades, and is completely waterproof when cured. The acrylic caulking in my older bath looks like new after more than 10 years. The silicone the plumber did in my newer bath turned yellow and mildewed in under 5.

Fill a spray bottle with soapy water (use liquid dishwashing detergent, which is a detergent not a soap). Spray anything you don't want caulk to stick to with the soapy water.

You're better off laying down a neat bead and never touching it than laying down a messy bead and trying to clean it up. Spend a little time cutting the spout to a shape that gives a good bead before starting. Practice on cardboard before going to the tub.

The tube you showed doesn't look like enough, a tube the size you put in a caulking gun should be. It's a pain to run out in the middle of a run.
