To achieve professional quality work on your staircase, it is recommended to follow these steps. First, it is important to finish all components before installing them. For the steps and handrail, you can use Osmo products, such as Wood Wax Finish for coloring and Polyx-Oil for finishing. For the risers and spindles, you can use Proprime white base followed by Polywhite satin or matte which must be sprayed.
