1. You will need the walls primed first for best results. Especially in the water closet area as you will have more moisture in the area than other rooms.

2. This one your wallpaper installer will answer. Typically they provide the paste.

3. Most wallpaper can be removed with a steamer by a professional so the factor of taking off the drywall is not is typical as it used to be. The steamer moistens the walls relieving the glue from adhering wen being removed.

4. This is personal preference.

5. Yes, a great installer will easily work around obstacles. I hope that helps!! :)

1. I have 90/10 smooth walls matte painted with SW. What wall prep is needed to give the best chance of easy future removal of the paper when it needs to get redone?

Remove any and all obstructions, nails, screws etc Repair cracks, fill in holes, sand etc as needed. Thoroughly clean the areas to be covered completely, prime etc.

For the water closet I would choose paper to be used for wet areas, can also be called wet wallpaper.

2) What type of paste/adhesion is the best quality? (I’ve read better quality brands don’t offer pre-pasted and to look for clear paste that does not increase its bond over time?) I’m sensitive to fumes.

It depends on the brand/type of wallpaper you purchase. The ones that are not pre-pasted, you will need to purchase separate paste. When applying paste, apply with a brush to achieve a damp cover and let it sit for a few minutes for the paper to absorb and the paper to expand and be ready to apply to wall. Do NOT apply the paper to the wall right after applying paste to the paper as it needs to expand. The paste needs to be tacky.

3) What type of paper that’s high quality and removable without taking the drywall with it? What’s best for bedroom vs water closet? (I’ve read vinyl isn’t good for bedrooms due to odor or bathrooms since it doesn’t let the wall breath, despite being washable?? So should I do non-woven, fabric, or..?)

Most paper being sold is easily removable via steam, or scoring tool and a spray bottle. Once it is wet most can be easily peeled off in entire sheets. For the left over paper on wall you can continue wetting and scrapping very easily until completely removed.

4) I love the idea of wallpaper with flocking. Is that practical for a water closet or bedroom? I’m thinking a damask for water closet and subtle striping for bedroom. Full wall, all walls (no chair rail or wainscoting)

This is more of a personal choice. If the bath area is exposed to steam, water, etc. I would use wallpaper specific for these types of areas. It depends on the type of bath and the area of bath.

5) I’m having exposed beams put onto my master ceiling. Do I just have the paper cut and done around them?

A professional can work around that.

Same for DIY
