Re-caulking a small section?

I caulked the gap between my tile and tub about 2 months ago. It looks great and is holding very solid, in part because it is right onto a refinished tub surface. I have one corner section that has a small bubble in the caulk and looks bad because it wasn’t tooled correctly. Can I replace just this section?

The section is about 6 inches long. I was thinking I would replace about a 3-4 foot section. My thought is to cut into the caulk under the tub spout down to the tub surface, then horizontally until I get a nice piece to grab onto and pull it out to the corner and around the corner to extend out another foot or two where I will also carefully cut. Then clean the tub surface really well and make sure it’s dry and go ahead and re-caulk. I really don’t want to re-caulk the entire tub and the caulk is so new that it is still bright white. I think the problem was that the caulk didn’t get enough time to cure and that area is where the most water collects. That is why I would plan to extend it out to about center tub.

I also have a curtain clip affixed to the tub and tile and would have to replace that if I wanted to re-caulk the entire tub. In addition the side gap between the tub and tile is about3/8” so that would be a lot of caulk to replace that otherwise looks brand new and is attached solidly. Thanks for the help!

 

Can I tape plastic over it and use the shower after 36 hours? I let it sit about 30-36 hours last time before we used the tub.

 

What type of caulk is it? Normally your plan will work, even if the fresh caulk shows some the difference will disappear over time.

 

It's bath and kitchen white caulk... thanks for the help
