Preparing The Surface

Preparing the surface is essential before plastering on top of wallpaper. This step ensures a smooth and lasting finish. Proper preparation can make the difference between a flawless wall and one that needs redoing.

Avoiding Common Mistakes

When it comes to plastering over wallpaper, there are a few common mistakes that people often make. Avoiding these can save you time, money, and a lot of frustration. Here are some key points to consider:

Ensuring A Long-lasting Finish

3. Allow Adequate Drying Time: Patience is key. Allow each layer of plaster to dry completely before applying the next. Rushing this process can lead to cracks and imperfections.
4. Protect Your Work: Once the plaster is dry, protect it with a quality paint or sealant. This adds an extra layer of durability and helps maintain the finish.
