Question 1

Do you need to prime before installing peel-and-stick wallpaper?

Accepted Answer

•

If you prefer peel-and-stick to traditional wallpaper, you can skip the priming process. Many manufacturers don't require an additional primer if you’re installing peel-and-stick wallpaper to painted walls. However, if you’re applying peel-and-stick wallpaper to unfinished drywall, you’ll need to apply a primer first.

Question 2

How do you layer wallpaper over wallpaper?

Accepted Answer

•

To layer wallpaper over wallpaper, inspect your existing wallpaper for problem areas. Damaged wallpaper should not be covered. If it’s okay to proceed, prep by turning off the electricity and removing any outlet and switch covers. Dust your walls and lightly rinse them to prevent the existing paper from peeling. Apply primer, then apply your new wallpaper.

Question 3

Why is my wallpaper not sticking to the wall?

Accepted Answer

•

The two most common reasons wallpaper does not stick are a lack of preparation and improper adhesive. Be sure to use the wallpaper paste designed for the type of paper you choose. Before beginning your project, make sure the walls are clean and free of dust, grease, and oils.

Question 4

How do I choose the right materials for finishing my basement walls?

Accepted Answer

•

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings.

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Question 5

Can you wallpaper over existing wallpaper and how many layers are recommended?

Accepted Answer

•

In most cases, it is not recommended to wallpaper over existing wallpaper, as the success depends on the type of paper already on the wall. While you might be able to cover non-coated wallpaper, you should never apply new wallpaper over a vinyl-coated one, which is more common. Doing so can lead to poor adhesion, resulting in bubbles, imperfections, and peeling. It can also trap moisture, potentially causing hazardous mold growth between the layers.

Even if the existing wallpaper is suitable, experts recommend applying only one new layer. Adding multiple layers (more than two total) can cause significant adhesion problems, leading to warping and bubbling. For the best results, the recommended approach is to remove the old wallpaper and all paste residue before hanging the new paper. If you are unsure about your wallpaper type, consider consulting a professional.
