Original Gorilla Glue is polyurethane adhesive, a type that needs moisture to cure. So you’re supposed to mist one surface of each mating pair of parts with water or wipe it down with a damp cloth. Then you need to keep the parts tightly clamped together for one to two hours, perhaps with tape if you don’t have clamps or if, as in your case, the parts are shaped in a way that makes it difficult to clamp them. But tape doesn’t hold well when the parts are heavy and damp, as you may have discovered.resin tray online
Try taping the pieces together when they are dry, without glue. If you can get them to hold, switch to a type of glue that doesn’t require you to wet the surfaces. Steel-reinforced epoxy, commonly known as liquid weld, works on cast iron. One example, J-B Weld Cold-Weld Steel Reinforced Epoxy with Hardener, costs $3.60 on Amazon.com for a package with one ounce of epoxy and one ounce of hardener. There is also a quicker-setting version, called KwikWeld. Although it is just two-thirds as strong, it would probably work just as well for your project. And it costs a few pennies less, at $3.27.
With either formula, clean the surfaces first, ideally with acetone (nail polish remover) or lacquer thinner. Or you can use soap and water, because grease residue probably isn’t an issue for a planter. Also scuff up the surfaces with rough sandpaper or a metal file. When the surfaces are completely dry, squeeze out equal-length noodles from each tube, mix the ingredients thoroughly for several minutes, then spread the goo and hold the pieces together with tape. If you use the original formula, wait four to six hours before handling and 15 to 24 hours before putting the planter back into use. KwikWeld sets in six minutes and cures in four to six hours.
If you can’t figure out a way to hold the pieces together while glue sets, a welding shop may be able to help you. Mark Bailey, who runs Metal Specialties in Spencerville, Md. (301-421-1832; metalspecialties.biz), looked at the picture you sent and said, “This looks fixable.” He would skip glue and instead weld the pieces together. This cure wouldn’t be cheap, though, in part because the welding rod he’d need runs $90 a pound. He estimated the repair would cost about $100.
A: There are ways that sometimes work to remove red dye from fabric. You can soak an item for half an hour in a solution made with one tablespoon of ammonia and half a teaspoon of liquid detergent per quart of warm water.
