Has anyone had problems getting cans of finish to close properly? I recently got a new can of Rubio and couldn’t get the top to seat correctly. I originally thought maybe I dented the lip or something, but I just got a can of Briwax and am having the same problem. There’s no visible dents or defects as far as I can tell.

When I put the top of the can on, it seems like it goes down all the way, but it sort of just floats back up and I can easily pry the top back off with my fingernails. It’s like it doesn’t grip the lid after I open it for the first time…. anyone know what I’m doing wrong?

I’ve run into that as well. It’s probably air pressure. Both of those materials will seal around the rim and lubricate it, so the pressure pushes it up. It’s more of a problem with nearly full cans, since the pressure increase is greater due to the smaller volume of air.

As long as it’s on well enough to be air tight, it’s OK.

Use the nailhole in the gutter trick to drain excess liquid. Use a block wider than the can and a mallet to seal the lid. Mallet the lid in three directions. Once seated, roll the can to slosh the contents around the lid on the inside.

Erik – could you show us some clear closeup photos of the rims of the cans in question ?
people that use finishes or paint on a regular basis, take the time to really keep the rims clean
of any excess finish or paint.
are you the one that used the finish last ? is there any chance that the lids could have gotten mixed up with another brand of finish ? (that’s a long shot there).
I know a guy that couldn’t keep the rim clean to save his neck.

I have had the same thing happen with Briwax cans, frustrating! I do the best i can and hope that with the plastic lid over it helps to keep it going bad. One can is duct taped since the plastic lid cracked

=1 on the Briwax. Reopened the can and the remaining wax was 1/2 the size of the can.

And make those gallon cans come with a spout installed in the lid. Too much of a PITA pouring a fresh gallon of lacquer into a filter cup for the sprayer 8^)

I know there are gizmos available for doing this, but the time has come for the paint can cabal to cede power!

Interesting as I have not noticed this problem.

Try this….. Oregon has a “recycle” deposit to keep unused paint out of the garbage (land fill) on all paint cans from $.075 to $1.50 depending on size. You only get it back if you return cans with left over paint and then some stores won’t take certain types of cans or paints and they must have their labels on. Some take metal cans but not plastic, some won’t take what they don’t sell.

Interesting, well I’m glad I’m not the only one! I’ll have to try cleaning the rim as a few of you suggested, although I’m the only one who uses these and should actually be pretty clean.

on some finishes, it only takes a thin film to “cement” the lid in place.
I use a very high quality marine spar varnish that is on the high end of the price scale
and if i don’t clean the lid and the groove with a solvent soaked rag, it will stick like super glue.
so pay attention to the lid and the groove equally.
the plastic lid on plastic containers of some finishes/sealers will also give you fits.
