If the cap of a paint tube breaks or cracks, you need to reseal the tube so the paint doesn't dry out. I've fortunately only had it happen a few times. I fold up a small piece of plastic wrap (clingfilm) into several layers, then put this over the top of the tube instead of the cap, and keep it in place with a small elastic band.

If the cap of your paint cracks or breaks Press-N-Seal works great to seal the moisture in nicely.

If a paint tube cap cracks in two just above the thread, I take a wide elastic band and keep the top of the cap in place by stretching this over the top of the cap and around the bottom of the tube.

Next time you finish a tube of paint, clean the cap and then store it for possible use as a replacement in the future.

I've lost or cracked the screw rims of the several tube tops; I've found the acrylic content will soften up when inverted in a glass of water, sometimes for days.
