Waterproofing basement?

I am getting water in the corner of my basement due to the 3 season porch in the back of the house that was unable to have waterproofing below it (exterior). I am thinking of using DryLok on the interior walls where the water is coming in as a temporary fix until I get money to do the exterior correctly, but the cinder block walls already have some paint on it. Can I still use DryLok on the cinder block if they already have paint on them or will this be useless...I know the DryLok needs to soak/seep into the pores of the block, but with paint already on them I don't know if i am just wasting my time????

The manufacturer only warrantees their product if it's going on bare, clean concrete with no paint on it. Check their website.

you need to get the water away from the outside of the house, slope the ground away from the side of the house so water runs away, waterproofing that is added to the inside of any basement wall will sooner or later leak due to head pressure from the outside.
