How do I properly paint over wallpaper borders or trims in an apartment?

Painting over wallpaper borders or trims in an apartment can be a relatively simple process if done correctly. Here's a step-by-step guide to help you:

1. Gather the necessary supplies: You will need a drop cloth or plastic sheeting, painter's tape, sandpaper (120-150 grit), a primer suitable for wallpaper, paint, paintbrushes or rollers, and a putty knife or scraper if needed.

2. Prepare the area: Clear the room of furniture or move it away from the walls. Lay down a drop cloth or plastic sheeting to protect the floor and any remaining wallpaper from paint drips or spills. Use painter's tape to protect adjacent surfaces like ceilings, baseboards, or moldings that you don't want to paint.

3. Inspect and prepare the wallpaper: Assess the condition of the wallpaper. If it's loose, peeling, or damaged, consider removing it prior to painting. However, if the wallpaper is in good condition and firmly adhered, you can proceed with painting over it.

4. Sand the wallpaper: Gently sand the wallpaper using 120-150 grit sandpaper. This helps to roughen the surface, creating better adhesion for the primer and paint. Sanding should be done lightly to avoid damaging the wallpaper.

5. Clean the wallpaper: Wipe down the wallpaper with a clean, damp cloth to remove any dust or residue from sanding. Allow the wallpaper to completely dry before continuing.

6. Apply primer: Apply a coat of primer suitable for wallpaper to the entire area you plan to paint. Use a paintbrush or roller to apply an even layer of primer, ensuring complete coverage. The primer helps to seal the wallpaper and provide a smooth surface for the paint.

7. Let the primer dry: Follow the manufacturer's instructions for drying time. Typically, it takes around 24 hours for the primer to dry completely.

8. Paint the borders or trims: Once the primer is dry, you can start painting the wallpaper borders or trims. Use a paintbrush or roller to apply the paint in thin, even coats. Multiple coats may be required for full coverage, so allow each coat to dry before applying the next.

9. Remove painter's tape: Once the paint is dry, carefully remove the painter's tape while pulling it away at a 45-degree angle to avoid peeling the paint off.

10. Clean up: Clean your paintbrushes and rollers with soap and water. Remove the drop cloth or plastic sheeting, and return furniture to its original position.

By following these steps, you can successfully paint over wallpaper borders or trims in your apartment, giving them a fresh, updated look.
