The New Hotness

  • Watching Paint Dry

    The rules for disposing of latex paint around here require that it be “dried with sawdust”, whatever that means. Over the years we’ve accumulated quite a lot of latex paint, in addition to a rich stockpile that Came With The House™, and I simply don’t have that much sawdust.

    Since they don’t seem to object to dried latex paint, I made a drying tub by stapling aluminum flashing around a stand that used to hold a water heater off the basement floor, lined it with heavy plastic, and started pouring latex paint into it:

    After a year of intermittently dumping paint, that solid latex cookie must be two inches thick and I suppose it’s time to toss the first batch.

    For what it’s worth, I discovered that storing paint cans upside down doesn’t guarantee that the paint remains fresh. This can had a solid latex cookie against the lid, with plenty of corrosion to go around:

    The coagulated paint above the latex cookie was as horrible as you might expect.

    Memo to Self: just throw it out, OK?
