Painting Over Wallpaper: Tips and Considerations Painting over wallpaper can be a viable option when removing it is too difficult or could cause damage to the walls. However, it requires careful preparation and the right techniques to ensure a successful outcome. Here’s how to paint over wallpaper effectively: 1. Assess the Wallpaper Ensure the wallpaper is firmly attached to the wall with no peeling edges or visible tears. If it is loose or damaged, it should be removed or repaired before painting. 2. Clean and Degrease Wash the wallpaper with a mild detergent to remove any dust, dirt, and grease. This step is crucial for ensuring the paint adheres properly. 3. Seal the Edges Use a thin line of clear caulk to seal the edges of the wallpaper at the seams, floor, and ceiling. This prevents the edges from lifting after painting. 4. Apply an Oil-Based Primer An oil-based primer is recommended as it seals the wallpaper more effectively than a water-based primer, preventing the wallpaper glue from dissolving and the paper from bubbling up. https://painters-adelaide.com,
