Advice on painting outside basement stairwell?

I need to paint the stairwell to the basement door. It's not very big, about 7 steps and about 36" to 40" wide. However, it is usually damp and doesn't get any sun. Bugs accumulate there, and the air always feels dank and humid. During storms it gets drenched and water sometimes pools away from the drain at the bottom of the stairwell.

The problem is, every time the paint chips and peels off within 2 years. This time I want it to stick.

I'm thinking of:
(1) Removing all the paint unless sections are stuck really well.
(2) Applying an oil-based primer.
(3) Applying an oil-based paint.
(4) Applying another coat of oil-based paint.
(5) Applying a weatherproof coat like Thompson's Water Seal.

Please edit my procedures.

Also, I expect this is to be a multi-day process so paint coats can dry. My plan is to do this over a 3-4 day stretch when no rain is expected. I have a fairly flexible work schedule. Should I do this work in the mornings or evenings?
