How can I re-coat my tub?

Hi Norma! Would your landlord help?

If it is help with caulking the tub, that is easy. Fill the tub with water and get in. That makes the tub as heavy as it can be therefore pulling it away from the walls. While these gap are at their biggest is when you should caulk. After caulking leave the tub full overnight to let the caulk cure. If it is painting the tub you want help with you should get that from the landlord.

if it is cracking he is using the wrong kind of caulk he needs a kitchen and bath silicone caulk it comes in white and clear - tear off the old, clean if needed and let dry for several hours then apply new caulk

All your needs must be addressed to landlord, not your responsibility. Also there could be perceived damage caused by you and charged to you if you "fix" it.

Kelli is right.

You should not be spending your own money on trying to fix the leak. It is the landlord's responsibility to ensure the necessary maintenance and repairs are made to the unit so that things function properly.

Despite your best efforts to try to improve the condition of the bathtub, you may loose your damage deposit, or even be charged for making 'unauthorized changes'.

You need to notify landloard, in writing. If you can't receive immediate correction, think about witholding some monthly rent, placing the money in an "escrow account". When renting, it is incumbent upon landlord to maintain the property in a habitable manner. You should never be incurring additional costs.

I agree with everyone else. If there's a problem with the bathroom, it's the landlord's responsibility to repair it.
