The following article will show you how to finish a basement staircase. Doing so is a big job; however, if you follow these instructions, it will be an easy one.

Step 1 - Preparation

Finishing a basement staircase can be messy. Place a drop cloth on the basement floor in front of and around the staircase. Place tape along the walls around the steps.

Step 2 - Clean the Staircase

Sand the surface of the stairs as well as the frame of the staircase. Doing so removes old paint and varnish to create a texture to which the new varnish can adhere. Wipe the staircase with a damp sponge to clean off the dust and open the pores of the wood.

Step 3 - Stain

Stir the varnish with a paintbrush and apply it to the surface. Apply a second layer if needed.

Step 4 - Treads

Basement stairs can be slippery. Place no-skid strips along the top of each step. Nail them into place through the center with a hammer and small nails.
