How to Wallpaper on Drywall TIPS

DEAR TIM: I was thinking of wallpapering several rooms in my house and installing a few borders in others. But after talking with some friends who have removed wallpaper from their houses I think I might not do it.

As they removed the paper they ruined their walls. The paper facing on the drywall was ripped off! Is there a way to prevent this? What can my friends do to restore their drywall? Darcey R., Brookville, IN

DEAR DARCEY: Ouch! I absolutely know how frustrated your friends must be. Tell them not to panic as there is an easy repair method that will restore the walls to like new condition.

Drywall Damage Preventable

The sad thing is that all of the damage to the drywall face paper could have been prevented. Whoever installed the paper skipped a vital step. They failed to size the walls before they hung the paper.

Sizing = Ancient Process

Sizing walls is a mystical process that generates lots of puzzled looks from clerks at paint stores as well as homeowners who wonder what it is. I can remember clearly the first time I heard the term.

I thought it meant you had to carefully measure the walls before you hung paper so that you purchased a sufficient amount of wallpaper. The truth of the matter is that sizing is a process that allows wallpaper to be installed with ease and at the same time allows it to be removed at some future time with little or no effect on the wall substrate.

Primer / Sealer = New Method

The word sizing tends to be used by older professional wallpaper hangers. New paper hangers just entering the field talk about priming and sealing walls instead of sizing them.

Many years ago paper hangers applied diluted wheat-paste adhesives on plaster walls to size them before they hung paper. This adhesive soaked into the fresh plaster and acted as a crude sealer. Modern technology has produced some amazing products that work much better than applying a thin wheat-paste to a wall.

Just A Few Tools

Let's get started with the tools. Fortunately, you don't need many tools to wallpaper.

Here's a list that will get you going on this job:

  • retractable razor knife with snap-off blades
  • 4.5 or 6-inch drywall taping knife
  • smoothing brush or plastic smoother
  • 4-foot level
  • grout sponge
  • measuring tape
  • paint roller & pan
  • paint brush

Plaster Wall Suction

Without the diluted adhesive coating the adhesive on the back of the paper sucked into the bare plaster too quickly. This made it difficult to adjust and smooth the paper. In some instances the wallpaper adhesive soaked so deeply into the plaster little glue remained behind to hold the paper to the wall.

New Adhesives

Modern wallpaper adhesives are very different than the old wheat-paste glues. Some are so strong that they can actually penetrate through many porous wall paints and actually grab onto the wall surface beneath the paint.

This is where many rookie paper hangers and homeowners get into trouble. They look at a painted wall and think that the wall has been primed and sealed. Indeed the wall may have a paint primer on it but this is not the right type of primer.

The new sealers create a barrier the glue can't get through. You absolutely need this if you're applying wallpaper over drywall.

The primer/sealers are perfect for painted drywall, bare drywall, paneling, and even existing walls that already have wallpaper on them. The products look just like paint and apply the same way.

Tint The Sealer

What's more, some brands are tintable. You can colorize the primer to match the background color of the wallpaper. This feature comes in very handy if a paper seam spreads apart in the future.

Extend Hang Time

The new primer/sealers also help you when you hang paper. They help to slow the drying time of the adhesives so that you have plenty of time to adjust and trim the paper as you work each sheet.

This characteristic is very important if you're double cutting paper as you install inlaid borders within a paper pattern. Not all wallpaper sealer/primers are created equal. If you want the best performance you will have to pay slightly more per gallon for it.

  1. Must walls be sized for each application of wall paper? I just removed a small section of paper, which came off nicely and I have removed all traces of paste. I thought I should size the wall, but can't seem to buy anything than enough to do a mansion .....
    I'm certain the original wallpaper was put on sizing, by the way it came off.
