Need suggestions for fixing, cleaning & water-proofing the basement walls


We live in a 1930's all-brick house, and the time has finally come for us to do our basement, which has been already demo'ed. We live about 3/4 of a mile from the water, and we are about 70 feet above sea level. Thankfully, the basement has no leaks through any of it's walls or the floor

As you can see by the photo, we need to fix cracks, scrape off the old paint/junk from the walls (blocks), have them waterproofed from any extra humidity / moisture and then painted. We will be using metal studs in the construction with green sheetrock everywhere (except ceiling), however there will be two machine-room closets (one for boiler / heater, and the other for electrical / gas meters) that will have the walls non-covered for
access.

Can anyone suggest what water-proofing, crack sealent and paint to use so that it lasts well and the walls don't start peeling in a couple of years?

Also, any other suggestions are much appreciated.

waterproofing is done from the exterior ( positive ) side,,, anything done inside ( negative ) is ' water management ',,, nothing prevents moisture/water from penetrating bsmt walls w/o good waterproofing,,, whether you're above sea-level or not, rainwater still collects about your foundation & bsmt walls,,, think of your bsmt as a ship's hull below the waterline,,, that's why even bsmts on top of a hill can be wet

IF there were no leaks, what appears to be some sort of ' dry-lock ' product would not have discolored / flaked / bubbled,,, interior moisture can be determined by doing a simple test - tape a 2' x 2' piece of plastic to the wall then check it in a couple days,,, if moisture is underneath the plastic, its moisture/water transmission thru the wall,,, if on top of the plastic, its bsmt high humidity

this has been discussed more than anyone cares to guess so do a simple topic search,,, remember, paint peels from moisture behind it

Thanks for your input.

It was suggested by someone that I should just used a product called "Fresh Cement", and go over all of the basement walls (concrete blocks) and to just seal them.

What about using wonderboard, instead of of green sheetrock? Or a combo of both?
Any comments on this?

you're welcome i guess if you can't see leaking water, there isn't any

1 of our most expensive projects 2yrs ago was replacing the collapsed garage wall of a customer,,, his wall had been leaking for yrs yet the interior walls glistened from all the fresh coats of paint,,, finally the leaking water combined w/soil acid salts had weakened the block's mortar & the cement used to cast the blocks themselves,,, down the wall came 1 rainy weekend eal them.

if ' wonderboard ' were to actually ' work ' for this unintended purpose, its deserving of its name,,, bear in mind most projects fail due to using the wrong mtls & / or poor methods / workmanship - your home, your choice
