Question 1

What are some common mistakes when finishing basement walls?

Accepted Answer

•

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes.

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Question 2

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.

Question 3

Is it a good idea to put wallpaper in a bathroom?

Accepted Answer

•

Yes, you can put wallpaper in a bathroom, but whether it's a good idea depends on several factors. Because bathrooms are high-humidity areas, it's crucial to choose a water-resistant wallpaper, such as one made of vinyl. Proper wall preparation is also critical to ensure the paper adheres well, even after many steamy showers. The wallpaper's placement also affects its longevity; it will hold up better on an accent wall or away from direct water contact, rather than immediately next to a shower. A well-ventilated bathroom will yield the best results.

Wallpaper lasts an average of around 15 years, but there is some variance. The type of wallpaper matters, as vinyl wallpaper tends to last the longest—sometimes 20 years or more—while a peel-and-stick wallpaper, which is the easiest to install for DIYers, will usually only last for around five years. Exposure to high humidity, smoke, and UV rays from sunlight can also limit the lifespan of your wallpaper, as can heavy traffic in the installation area.

Question 5

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.
