Title: T-molding re-installation
Post by: opt2not on October 04, 2018, 07:58:47 pm
Concurrently with another thread asking how to fix t-molding slot mistakes, I'd like to get advice on re-installing t-molding without destroying the slots when pulling out the old t-molding. 

Every cabinet I've restored, I've found that after removing the existing old beat-up t-molding, the slots end up getting wider because bits of the wood gets torn away when the old stuff is pulled out.  Requiring you to wood fill/bondo the slots and re-route. 

This is a lot of extra work for refreshing the t-molding, which got me thinking what is the best way to remove t-molding without damaging the slot? Can it be avoided?

I'm debating just shooting a bead of adhesive into the groove with a caulking gun and then installing new molding.  A lot easier than bondo and re-route.

I've just used silicone caulk in the groove.

The way it’s barbed you’re pretty much going to pull out wood. I find that a dab of hot glue here and there along the installation is all you need. Especially on the bends. A friend of mine folds electrical tape over the barb to make it bite better.

I wonder if there's a way of pulling up the t-molding just enough to fit a blade under the flat part, and cutting the "t" part off. Then perhaps sliding the teeth part along the edges and out, rather than pulling perpendicular to the edges...

As the others have mentioned I have just used hot glue in the past.

Disclaimer - Although I've heard this has been done, I myself haven't tried it. Using a dremel (perhaps with a routing attachment) cut the spline area of the tmolding allows for easy removal. I would try first on a scrap piece to see if this might work? Just throwing ideas out there.

I have often worried about installing the T molding after paint etc, and presume its gonna be a "Do it right the first time" situation because any removal will pull something with it. It's just the nature of barbed stuff. I don't know if much of anything would help reduce it on older cabs because of the material used and how it has likely swelled a bit over time, making the mold tighter. I have noticed some T mold has thicker barbs than others, and have to take this into consideration moving forward.

Perhaps heating the T mold would make things more pliable, dry out the wood, and maybe help open things up some before removal? I have never tried or even considered it until now, but maybe it could be a way to make it easier to remove, and less damaging to the wood.
