Pros of using Gardz for wall repair

Gardz is a reliable solution for sealing wallpaper glue and has several advantages:

  • Gardz acts as a problem surface sealer, effectively sealing in old wallpaper glue and adhesive residue.
  • It has a milky blue-white color that helps determine where it has been applied but dries water clear, providing an invisible finish.
  • Gardz can be used directly from the container, making it convenient and easy to apply.

  • By sealing the wallpaper glue, Gardz helps prevent the glue from reactivating and weakening the paint or wallpaper.

Cons and limitations of using Gardz

While Gardz offers many advantages, it also comes with a few limitations:

  • Gardz may require multiple coats for adequate sealing, especially if the wallpaper glue is particularly stubborn.
  • It can be time-consuming to apply Gardz over large areas or multiple layers of wallpaper glue.
  • Gardz is not recommended for use on heavily damaged or unstable walls, as it is primarily designed for surface sealing rather than structural repairs.
  • There is a possibility of the Gardz reacting with certain types of paint or wallpaper, so it is important to do a patch test before applying it to the entire surface.
  • It may not completely remove the visual appearance of the wallpaper glue, especially if it has left behind deep stains or texture on the wall.

Alternative solutions for sealing wallpaper glue

If Gardz is not the right choice for your wall repair needs, there are alternative solutions you can consider:

  1. Removing the wallpaper glue manually by scraping it off the wall with a putty knife or sanding it down.
  2. Using a wallpaper glue remover or adhesive stripper specifically designed to dissolve and remove stubborn wallpaper glue.
  3. Applying an oil-based primer/sealer, such as Sherwin-Williams ProBlock Interior Oil-Based Primer, which can effectively lock in the wallpaper glue and provide a suitable surface for paint or wallpaper application.
