[step] No matter how careful you are, there's a good chance a few drips will fall on the stairs when you paint. Use drop cloths or old sheets to protect the stairs.

Ending1: [substeps] If there are any hanging pictures or removable fixtures on the walls of your staircase, you may want to remove them before you begin painting. Be very careful when walking on the stairs, especially if they are wooden, as the cloth will make them slippery. Ending2: [substeps] If you already have drop cloths, place them next to the stairs, so that you don't need them when you're painting. Alternatively, get a large enough drop cloth to cover your ceiling. Ending3: [title] Pour in additional amounts of paint when you finish priming the stairs. [step] For even more coverage, add a drop of the finishing primer to each step. Ending4: [title] Lay on floor tacks or masking tape to check the paint level. [step] Once the ceiling is covered with drop cloths, carefully remove them.
