I may try to use a heat gun and gently bend the corner down a bit on one of them to see if that helps. It seems like such a minor thing, but when the whole ceiling has all those little gaps in it, it looks bad.

Maybe do a combination of both. Put a weight on the corner (doesn't really matter what), heat the corner with a hair dryer or heat gun. Then after the tile has cooled, remove the weight.

They look great, but since they are a lot thinner than the acoustic tiles, they tend to not lie completely flush against the grid in some spots - mostly corners.

Does anyone have any ideas for how to resolve this? I don't really want to use any kind of adhesive, unless it's something designed for this, that would let me remove the tiles easily somehow. I also thought about using some type of weight on top, but not sure if that's a great idea either.

Any advice would be most appreciated.

Thanks!

I'm kind of a expert on this subject. We installed miles of this stuff. Its not unusual for this type of tile to not sit down completely everywhere, especially in the corners. It's just the nature of that grid and tile system. The weight of the tile is pulling down in the middle causing the corners to rase up. Especially if its a 2X4 vs 2X2. The only thing you could do is put some kind of weight on each corner. Honestly I would not bother. You can try hold down clips. Ask your specialist supplier about that.
And remember, sometimes the more you mess with a grid ceiling the worse it will get.

in case the tiles are slightly bent, you could try a hair dryer on low, after all don't want to melt them.

Try Museum Wax. Non-toxic and removes easily. Press it on the corners and place a weight on it for awhile. When you remove the weight it should hold.

Thanks! Just ordered some. I also got a small pack of ceiling tile clips - which are supposedly for this purpose, but I read don't work very well.

You want to lay the tiles on the surface so they lie in a uniform plane? Warm them up so they are more flexible. The vacuum trick is cool and will help position them. Weight would just make them sag eventually.
