Cooler Hacks: Add a Seal to a Cheap Cooler

There are lots of reasons to spend a lot of money on a cooler. For starters, expensive coolers tend to be chock full of features that not just keep food and drinks cold but also last darn near forever. However, if you’re the type of person who wants the former but can’t justify shelling out hundreds of bucks for a cooler, check out this cooler hack. 

When you compare expensive coolers with cheap coolers, you might notice that inexpensive coolers seldom have a gasket seal between the top edge and the lid. This seal, as you can imagine, keeps cold air from escaping. Fortunately, there’s a hack for that. 

  • The first step is to buy some foamy double-stick mounting tape from a hardware store. Use the super sticky kind made for outdoor surfaces.
  • Second, clean the surface of the cooler’s top edge — the place where it contacts the lid with rubbing alcohol. And then make sure it’s good and dry. 
  • Third, apply the sticky side of the tape to this surface. Try to do each of the four sides in its own continuous length of tape. Trim for width as necessary.
  • Lastly, you can either leave the peel-off coating in place on the exposed side of the tape or, if you’re seeking a bit of a sticky seal, peel off and lightly coat the now sticky surface with baby powder or talcum.

When the tape eventually comes off, it’s easy to replace with new, but it adds a seal your inexpensive cooler never had before.
