When it comes to wallpapering, size counts—and I'm not talking about the girth of the wallpaper roll!
Wallpaper size is essentially a thin, watered-down wallpaper paste solution that is applied to the wall before hanging wallpaper. It prepares the surface, helping the wallpaper paste grip better while still allowing for easy repositioning during installation.
You can buy dedicated Wallpapert Size product or choose a wallpaper paste that can be diluted and used as size, so there’s no need to buy a separate product—just check the instructions on your chosen paste for dilution recommendations.
While not always essential, we highly recommend using size if:
✔️ You're installing paste-the-paper wallpaper
✔️ Your walls are absorbent, porous, or unsealed
✔️ You want to allow more flexibility for adjusting panels during hanging
Applying size only takes a few minutes but can make wallpapering much easier and help prevent peeling or lifting later on. If you're unsure whether you need it, feel free to contact us, and we’ll be happy to advise!
