1. Check Out The Open Seam

The first and foremost step is to inspect the wallpaper area with loose seams. It’s really important because you can’t fix the issue unless you get to know about the underlying cause of the problem in the first place.

For this purpose, you can lift the seam using a putty knife and just slightly (if the seam is open along all its length) to check whether there is dust or dirt on the wall. While doing so, you need to be very careful in order to not cause any tearing damage to your wallpaper because that will cause more harm than good.

Also, there may be damage to the drywall (as explained earlier) and you need to fix it using a wall filler or filling compound. Similarly, it can possibly happen that the seam is loose at points while strictly attached in between and all its length.

If that’s the case, it is recommended that you try to detach the attached parts of the seam so as to ensure smooth seam adjustments afterward.

4. Apply Wallpaper Seam Adhesive

Now that you’ve eliminated the underlying cause of the problem and have also fixed ripped seam edges (if any), it’s time to get the seam attached to the wall once again. Always make sure that there is no dirt or dust along the inside of the peeling wallpaper edge.

Next, you need to apply wallpaper seam adhesive into place and run the foam roller with gentle pressure over the seam. After that, you can make use of a smoothing tool to get the work done by resealing the seam properly.

5. Clean Up The Excess Adhesive
