Interlocking Tile Replacement

[Anthony Angotti]

Hello,

I bought a unit with an interlocking tile ceiling. There are a couple tiles that are sagging and a couple that have some water stains (working on eliminating the source).

I'm having trouble getting new ceiling tiles in (Armstrong interlocking tiles circa 2007). I've looked up a few things online, but am still having issues. Has anyone had any success replacing individual pieces without taking the whole thing apart?

I've considered just cutting the tongue and groove pieces off an putting them up with finish nails if that would work. For the water stained pieces I don't know if painting over them would work.

@Anthony Angotti, yes, with patience and care, pieces can be replaced.  It's a lot like toothing-in tongue and groove flooring... typically on the last piece or two have to have the tongue or backside of the groove removed to install and a dab of adhesive often does the trick.

If you opt to paint, use a primer/sealer first (such as Zinnser or Kilz), but know that the painting will be noticeable.
