basement waterproofing

This house was built in the 1940s' and water is coming in through the mortar joints in the rear wall of the basement. It has a brick foundation.
I am not going to use drylock or any other stuff of thls sort as it tis toxic and this is a rental. There is a family living in there.
I coated most of the wall with hydraulic leak stopper from Lowes but working with it is a pain as it sets too quickly.
Can I stop using that stuff and switch over to regular mortar and put on a few coats to cover the whole area a few times?
Any other ideas?

Waterproofing is done outside with gutters, downspout extensions and grading and/or by digging out the wall to the foundation and applying the 'proofing' material on the outside of the structure. You are talking about methods of trying to stop the water when it's already 99% of the way inside.

If working outside is not for you, a water mitigation system might be the next thing you should research.

What makes you say that? While the old oil base drylok had a strong odor, the latex version does not.
That said, it's always best to stop the water infiltration from the exterior side!

drylock's toxic ? whoever said that ? actually the fine aggregate it contains is ' ROUGHAGE ' & good for 1's diet,,, actually what you already did is idiotic to many - me included,,, wrong material & wrong method,,, either you need to work from the outside OR learn how to manage the leaking water

The best long term solution is to prevent the water from reaching the foundation. Sometimes there is no solution (e.g. high water table) but sometimes there is.
