Preparing walls for painting after wallpaper removal involves several crucial steps to ensure a smooth, professional finish. Don't rush this process; proper preparation is key to a beautiful paint job.
Essential Steps for Wall Preparation
-
Assess the Wall Condition: Carefully inspect the walls for any damage left behind after wallpaper removal. This includes holes, cracks, uneven surfaces, and residual adhesive. Note the extent of the damage to determine the necessary repair steps.
-
Clean the Walls Thoroughly: Remove any remaining wallpaper glue or adhesive residue. A mixture of hot water and trisodium phosphate (TSP) can be effective, but always test in an inconspicuous area first. Thoroughly rinse and allow the walls to dry completely. [Source: NewLifePainting.com]

Repair Damaged Areas: Fill any holes or cracks with drywall compound, using a putty knife to smooth the surface. Allow the compound to dry completely, then lightly sand the area to achieve a smooth, even surface. [Source: CougarPaintingKC.com, Bunnings Workshop]

Sanding for Smoothness: Lightly sand any rough patches or imperfections on the wall's surface. This step helps create a smooth base for the primer and paint. Focus on areas with texture or raised surfaces. [Source: Inexteriors YouTube videos, CougarPaintingKC.com]

Prime the Walls (Crucial Step): Priming is essential, especially after wallpaper removal. Primer seals the surface, preventing the old wallpaper glue or adhesive from bleeding through the paint. It also provides a uniform base for the final coat of paint. Choose a primer suitable for your wall type and the level of previous damage.

Painting: Once the primer is dry, you can begin painting. Apply two coats for optimal coverage and color vibrancy. [Source: Inexteriors YouTube videos]
Optional Steps (Depending on Wall Condition):
- Skim Coating: For walls with significant damage or severe texture irregularities, a skim coat of joint compound may be necessary. This involves applying a thin layer of compound over the entire wall surface for a completely smooth finish. [Source: Reddit DIY]
