hello, i plan on redoing the caulk around my tub because there is one or two spots that shows a crack on it. I think the contractor **** up or the caulk, this was done probably a year ago. Is it necessary to re-caulk the vertical walls shown in the picture below in green lines when you re-caulk? There is nothing wrong with the caulking there, looks brand new. I was just thinking of re-caulking along the tub only shown in picture below in red lines. I am afraid that the caulking will not adhere correctly at the vertical corner? or am i worrying too much and just overlap it at the corner to give it a good adhesive? i will be using ge silicone 2 kitchen and bath. thanks for reading.
Any loose pieces of mortar - just scrape it out -- its not doing anything anyways.
Masking tape above and below the caulking line --- don't put too much caulk down--- wipe once across the caulk with your finger to smooth it out---resist temptation to go over it multiple times with your finger to make it "just a little bit better"---pull off tape. Probably others will chime in with their preferred methods to apply caulking, but that is mine.

thank, i will remove that loose unsanded grout in the change in plane, that was probably why my caulking split open from the corner when it cracked, i will remove any loose grout and re caulk everything thanks
New silicone will not stick to cured silicone (almost nothing will stick to cured silicone). If that is silicone that is currently on your tub (and it probably is), you have to do an extremely thorough job of removing all of it. If you do a search, there was an old thread with a very thorough description of how to remove all traces of silicone. Its not easy.
thanks, i spent the whole day removing silicone scraping away. I came to a situation, should i caulk over this crack grout? or remove it and than caulk it inside as much as possible first than finish it with a nice caulk line? the gap is not too big but not a small as expected. here a picture shown, i do not have the option to remove the tile too.
