My daughter was trying to do a good thing and bought two 2×4 KALLAX units off FB for a sick friend.
The units were incredibly dirty, but they were cheap and we were going to clean and disinfect anyway.
However, some of the veneer started to come loose as we loaded the pieces into the truck. It started to rain on the way home, and by then, the veneer pieces were practically sliding off in places.
Looking at it, it appears the owners knew there were problems, as there are a couple splotches of hot glue underneath.
Some of the scratches swelled from the water exposure too.
So… my daughter’s heart is sad and I’m trying to see how we can salvage the situation and fix these units.
I’m not sure what kind of glue to use or precautions we should take. Any advice is greatly appreciated!”

KALLAX is made from particleboard. Water is its kryptonite.
The first thing to do is to assess the damage. How severe is the water damage? Are many of the panels swollen and warped?
If so, it may not be worth saving. And your daughter may be better off buying another set of pre-loved KALLAX.
Next, do you have time to let it dry thoroughly? Wet particleboard can easily sag under weight. If not thoroughly dried, it may also provide a fertile ground of mold and mildew. If so, again you may want to discard it.
How to fix water damaged particle board
Let’s say, it’s salvageable. Then this is what I’ll recommend.
First, let it dry thoroughly. Either naturally or use a hairdryer.
Sand down the areas that “bubbled up”, with a fine grit sandpaper. Then use wood filler to repair the surface and other scratches. Sand it down again to smoothen the surface.
For the veneer edges that fell off, try using veneer glue to stick them back on. Remove any residual glue from the veneer strips first. After applying the glue, clamp the strips down to cure. (Follow directions on the product.)
