Yes, wallpaper can be pasted on painted walls.
Painting a wall beforehand creates a suitable surface for wallpaper application and, in some cases, can even aid in easier removal later on. Whether the paint is flat or semi-gloss, wallpaper can generally adhere successfully.
Here are some things to consider:
- Surface Preparation: While painting is generally acceptable, proper wall preparation is crucial. Make sure the painted surface is clean, dry, and free of any loose paint chips, dust, or debris.
- Priming: While the reference suggests sizing may not be necessary, consider using a wallpaper primer. Primer creates a more uniform surface, promotes better adhesion, and can make future wallpaper removal easier.
- Paint Type: While the reference states flat and semi-gloss are acceptable, extremely glossy or oil-based paints might require scuff-sanding to create a better grip for the wallpaper adhesive. Test a small area first.
- Wallpaper Type: Different wallpaper types have varying adhesion requirements. Follow the manufacturer's instructions for the specific wallpaper you're using.
- Adhesive: Choose the appropriate adhesive for your wallpaper type. Pre-pasted wallpaper or traditional wallpaper paste can be used depending on the wallpaper you have.
In summary, while it's generally acceptable to wallpaper over painted walls, proper preparation, including cleaning, priming (potentially), and choosing the right adhesive are crucial for a successful and long-lasting result.
