Do you have a threshold in your laminate floor that just keeps popping up?  In this post, we’ll show you how to fix that, permanently.

Laminate thresholds normally fit into a channel that’s been screwed or nailed into the subfloor.  Sometimes, people just pop the threshold into that channel without any adhesive.  Sometimes, they just use the wrong adhesive.

With the example in this post, the installers used regular siliconized acrylic caulk.  While this is great for filling holes and gaps, it’s not the best adhesive.  To repair the threshold, you need to clean the old adhesive material off the channel and the threshold to assure a good adherence with the new adhesive.  Then, apply the new adhesive (use a construction adhesive like Liquid Nails) into the channel.  Do not apply it to the threshold, especially to the “flanges” of the threshold, as this will cause the adhesive to leak out onto your floor and make for a tough clean-up.  When you put the adhesive in the channel, it will ooze out into the flange area without leaking out onto the floor.

To re-install the threshold, you just carefully place it back in the channel.  This may require a little force and you might want to use a clean towel on top of the threshold to prevent marring the finish.  Once it’s back in the channel, be sure to place something heavy on top of the threshold to keep it in place while the adhesive sets (generally, about 12 hours).  Again, you will want to have some sort of protection between the threshold and the heavy object(s).
