Remove all the furniture from the area of the basement in which you will work. Spread tarps over the floor.
Scrape the wall well with a paint scraper to remove peeling and loose paint. Use a ladder to reach high areas if necessary.
Apply a coat of paint primer over the whole wall with a standard paint roller. Let the primer dry for 24 hours.
Place textured paint on the wall using a textured paint roller. Start at one upper corner of the wall, and spread paint over as much area as possible from one position while using up-and-down configurations. Roll on the textured paint as thickly as it will stay on the wall.
Move to the next section of wall and continue painting by using the same procedure.
Step back from the wall and assess the paint's appearance. Ensure its texture is consistent between the two sections you painted.
Apply the textured paint to remaining parts of the wall section by section, working your way across and down the wall. Assess the paint each time you finish a section to ensure the texture is consistent throughout the surface. Let the paint dry for 24 hours before moving furniture back to the area.
