Herein, how do you use wallpaper paste to size a wall?
The modern way of sizing is to prepare a runny mix of paste, roll the wall area and brush in around the edges. You'll see the filler darken when you apply the paste. This is good because the filler is absorbing the paste now, and won't be able to suck the paste off the back of the wallpaper later.
Beside above, how long after sizing can you wallpaper? Needs 2 hours to cure before wallpaper can be hung. Size will only be active on the surface for up to 3 days. Once the surface has been coated with size, you are then ready to begin wallpapering.
