+Birdsong-n-Bud Posted November 12, 2004 Share Posted November 12, 2004 I would like to create my own microcache with a rock glued onto it or a magnet, but I'm used to glues that are used for indoor projects. What kind of glue will hold a rock or magnet through rough New England winters and hot New England summers? Quote Link to comment
+fly46 Posted November 12, 2004 Share Posted November 12, 2004 They make High Heat hot glue. (It's a special kind, but available in walmart, etc) That's probably a good bet. Quote Link to comment
+briansnat Posted November 12, 2004 Share Posted November 12, 2004 PC7. is really good. So is Outdoor Goop Adhesive and Sealant. Quote Link to comment

What kind of glue will hold a rock or magnet through rough New England winters and hot New England summers? 3M 5200. Outdoor Long Full Sunlight Exposure, Salt and Fresh water, non shrinking. You can find it in Tan, Black, White or something called Mahogany. Long working time. Service temperatures from -40 to 190 F. It's a thickish paste so it's completely gap filling and it hardness to a very firm rubber feel which stands up well to vibrations, like getting stomped on. Fully UV (sunlight) resistant (unlike Outdoor Goop or epoxy based products). They use it all over for permanent boating applications from Maine to the tropics. This stuff is great. You can find it in small tubes all over the internet or local boat stores and and hardware stores. You won't be disappointed. compare at $6.95 for 3oz. from Amazon 3M 5200 @ Amazon I've seen 1oz tubes for about $3.00. Edited November 13, 2004 by twilliams Quote Link to comment
+BlueDeuce Posted November 13, 2004 Share Posted November 13, 2004 (edited) I have no doubt that 3M Marine 5200 is a good adhesive, but I wonder though if it might be too good. The are concerns when working with a high grade glue, such as gluing your hand to your head. Many woodworkers use Gorilla glue which is in more in line with household usage. It's Outdoor graded and 100% water proof. Outdoor Titebond is another very popular glue. I know of another glue that I have used for years and Consumer Reports rate as one of the best, (It has a thumb logo on the package) unfortunately I can't remember the name off the top of my head and of course when I need to find it, it's missing. Give me a bit to look. I use it everywhere. From my children making Mother's day cards, to gluing ceramic cups, to repairing stepping stones and it won't require a trip to the hospital if you get it on your fingers.

(great for naturally finished outdoor furniture where you need strength, or areas where gap-filling through expansion is helpful). Also a plus, Polyurethane glues are supposed to work on "stone" but I've never tried that. Let's face it gorilla glue is pretty messy (it expands/foams 4:1! Especially with surfaces which have some moisture) - some people complain about it forcing joints apart after they've left a piece to cure. and it stains. If you use gorilla glue then I'm sure you've had those brown stained hands (yeah yeah, I use gloves now). {it also can ruin the later application of some finishes} But more to your point; Gorilla has a pretty short working time and then it goes off like epoxies, actually worse since it expands. But 5200 has a very long working time, time to get things right before you clean up and leave your piece overnight. But since it's not a liquid but more of a goop, you can leave it and it won't run, expand, or stain. You can shape it like a caulk, so that you can easily create a bead around a magnet, let's say for both waterproofing and extra adhesion. Of course, you're right that gorilla glue is a great glue, but for this application don't be scared and try the 5200. I bet you start using it for other things.

+JohnnyVegas Posted November 13, 2004 Share Posted November 13, 2004 The only thing I have ever used for caches is a hot glue gun without any problems, that's if you don't count I have glue my fingers. Quote Link to comment
+Prime Suspect Posted November 13, 2004 Share Posted November 13, 2004 Another vote for JB Weld. It fills gaps, but doesn't expand like gorilla glue, so everything stays just where you put it. Quote Link to comment
+Fergus Posted November 13, 2004 Share Posted November 13, 2004 Whenever I need to use glue on a cache container I use PC7. It is a two part plumming epoxy that you should be able to find at your local hardware store. make sure you let the epoxy fully cure before you place your cache. Quote Link to comment
+Runaround Posted November 14, 2004 Share Posted November 14, 2004 I use JB or Gorilla Glue depending on the application. I find Gorilla Glue is better on porous materials and JB on non-porous. In a pinch, either work well. The trick to getting good results with Gorilla Glue is solid clamping since it expands as it cures. If you can't clamp, its just going to pop your items apart.

What kind of glue will hold a rock or magnet through rough New England winters and hot New England summers? I got creative and used stuff I could find from around the house. I settled by using a 35mm film can and taping a refrigerator magnet to it by wrapping a few layers of electrical tape around all of it. Crude, yet effective and it's all black and difficult for muggles to notice. Just my quick and easy solution. Quote Link to comment
