Dear James: We are remodeling our house and will remove the wallpaper. Some is that difficult shiny type.
What are tips to remove it without damaging the drywall?

Dear Jeremy: Wallpapering is less popular than it used to be. One of the major reasons is the difficulty in changing the decór in the future. It’s much easier to just repaint.
For more decorative walls, faux painting is becoming much more popular.
Although some wallpaper removal techniques work faster than others, actually there is no “quick” method.
If you try to rush through it, you will just gouge the drywall and end up spending more time overall having to repair all these spots and clean sanding dust.
First, if the wallpaper surface seems slick, determine if it is the vinyl-coated type. Using a sponge, dampen a small spot and wait about 30 minutes. Try to scrape the area with a wallpaper scraper. If it is not loose at all, then it probably is vinyl coated and it will resist water.
By your description of its appearance, let’s assume that it is vinyl coated.
The trick to stripping it as quickly as possible is to break the surface in as many spots as possible. This allows the water to penetrate and soften the old glue so that you can peel off the wallpaper.
If you are careful, you can score the wallpaper surface with the edge of a scraper. Score many times in a crisscross pattern. Just break the surface. Don’t score it too deeply or you will get into the drywall paper coating, and this will cause problems.
Another alternative is to buy a special wallpaper piercing tool at your paint or hardware store. It has spiked wheels inside that pierce the wallpaper surface when you roll it over the wall.
Spending a little extra time rolling it to create many holes will save stripping time overall.
Now you have prepared the wallpaper and you are ready to begin the stripping process.
Plain warm water is effective, but using the enzyme-based additives will dissolve the old glue much faster.
DIF enzyme stripper, by Zinsser, is one of the best products to use.
Spray the enzyme solution on the wall with an old Windex spray bottle or sponge it on with a large sponge.
Have plenty of ventilation. Although the enzyme solution is not harmful, it makes some people cough. Be patient and give it about 30 minutes to dissolve the glue.
Spray another section of the wall and let it soak while you scrape the first section.
Use a standard wallpaper scraper. Holding it at about a 15-degree angle seems to remove the wallpaper well without excessive damage to the drywall underneath. Don’t worry about a few nicks in the drywall.
Once the wallpaper is removed, you will have to scrub the wall to remove all the residual glue. If you do not do this, it will bleed through the paint in a year or two and look terrible. Use a large grout sponge and the enzyme solution. Wash it down with soap and water when you are done.
Now, unless you are the Michael Jordan of wallpaper stripping, you have probably damaged the drywall in some spots.
To fix these gouge spots, first paint them with white shellac or other stain sealer. This blocks the moisture from the drywall joint compound from penetrating the drywall.
When the shellac is dry, fill the gouges with a thin layer of the drywall joint compound. Use several layers and sand between coats.
When completely sanded and painted, the repairs will be invisible.
