Recaulking Bathtub for bathroom

[Paiea Palomanu]

So I have just brought this duplex, my first DIY project is recaulking this bath tub. Towards the middle the gap between the tub and the Tile was getting significantly bigger then a quarter inch. I was trying to figure out what to fill in the gap with before caulking ? I read a foam backer rod could help I just wanted to hear from people with more experience than me lol.

Foam backer rod, definitely.

And if this is your first time caulking, use blue painters tape along the tile and the tub. Caulk in between the two strips and smooth it.

When you pull the tape off, you’ll have much cleaner lines!
