Reddit mentions: The best tile epoxy adhesives

As long as this doesn't go in the oven (or get hotter than 180ºF / 80ºC) of course it can be glued, and with fine, strong (but still slightly visible) results.

u/GondorUr is probably right, it would be easiest to return it and that would have the best results, but...

u/pobroin has the right attitude, considering their appreciation of kintsugi, and so do you, I presume, since you are asking about repairing, rather than replacing.

u/BcookieOmonsterB is right, that cyanoacrylate (Super Glue, Krazy Glue, etc.) works well with ceramics, but cyanoacrylate works best on nonporous surfaces, and when the surfaces fit really well with the least possible gap. On ceramics, especially if not fired to the point of being vitreous, there's often a few grains that will get dislodged in the glue, while fitting the pieces back together, that will stand in the way of ever getting a truly close fit. So...


As this job is a nice clean break, and a simple two pieces. It's the perfect job for a two-part epoxy, which is plenty strong and will fill any small gaps with virtually no loss of strength, unlike cyanoactrylate.

Your best option to repair (rather than replace) is a two-part clear epoxy. Since you're asking about this, I assume you haven't worked with glues much, and are unfamiliar with the process, and may be a bit slower than someone more practiced. Different epoxies have different working or handling times, and since you don't want to rush it, look for longer than 5-minute epoxy (this one gives you a full 30 minutes, but that's a lot longer than you should need for this simple job - look for a 10-minute epoxy).

• Dry fit the two pieces together to make sure they do fit well, and dust off any loose grit or chips that remain on the broken surface. Don't clean the surfaces with any water, soap, or cleaning agents, just a clean dry toothbrush or similar.
  
  
• Lay down some newspaper or something else disposable to protect your table/counter/work-surface (a sheet of parchment paper works really well here, as drips are less likely to stick the paper to your lid). There will almost certainly be drips.
  
  
• Get some tape and have it close to hand for clamping the glued pieces together, later. As the lid has a nice smooth glazed surface,almost any tape will do, but something with just a little bit of stretch, like electrician's tape or duct tape would be best, as you can pull the tape a little tightly across the mend, and the elasticity of the tape will give just a little of a slow steady tug, to help to squeeze out excess glue,and snug the two halves together.
  
  
• Squeeze out equal amounts of resin and hardener (or whatever ratio the instructions recommend, usually it is 1:1, and the double-syringe tubes, like the one I linked to above, help you keep the amounts fairly equal) onto a disposable surface, such as a clean tuna can lid, a piece of parchment paper, the bottom of a soda can,whatever,and stir them together really well with a popsicle stick, a nail, a cuticle stick, or some other disposable applicator. Stir well, making sure scrape all around the edges of the puddle, to incorporate all of the two components, so it is fully and evenly mixed. Also, make sure you mix up more glue than you will need, because you want to do the gluing all in one go, especially if you are using one of the quicker 5-minute epoxies.
  
  
• Place the lid halves on your protected work surface. Using your mixer/applicator, smear a line of epoxy all along the centerline of one of the broken edges, about a third as thick as the edge. Doesn't matter if you go thicker, but don't go much thinner, and do make it a continuous bead, all along, from end to end.
  
  
• Slide your two pieces together, carefully lining them up as accurately as possible. Press them together firmly , keeping your hands down at the edge for the most part, perpendicular to the crack (crack runs north to south, hands at west and east).
  
  
• Take a strip of your tape and stretch it across the glueline, from one piece to the other, down there just above the rim, pulling the tape a bit tight to give it some stretch. Do the same for the other end of the crack, again, just above the rim. (NOTE: you start here at the rim, rather than in the middle, up near the knob/handle, because downward pressure up there at the center, could press the center down, rocking the two outer edged of the two halves up and away from each other. Out at the rim, downward pressure has almost no torque to tip the halves.) Now add about three other strips of tape, spread out along the glueline. (Edit: additional strips, again, go west to east, from one half to the other, across the glue line, not along or in line with the glueline, with a bit of stretch/tension).
  
  
• Flip it over and and place a couple more strips of tape on the underside.
  
  
• Before the glue has cured (hardened), using a clean dry cloth or paper towel and acetone, mineral spirits or isopropyl alcohol, gently wipe up any excess epoxy that has squeezed out the crack onto the surface.
  
  
• Leave your work undisturbed, to cure, for the recommended amount of time, however long it is, 5, 10, 30 minutes, before handling it any further, and allow a full 24 hours, before putting the lid to work
  
  
• After curing, remove the tape, and use a sharp knife or razor blade to carefully and thoroughly scrape off any excess cured glue there.
  
  
• Wash and proudly put into service.
  
  Edit: Yay! Silver! Thanks for the alms, secret Samaritan.
  
  Edit 2: Clarification added to taping procedure

You could get some 2-ton epoxy and carefully apply it around the hinges with a small disposable brush (like the ones that come with kid's watercolor paint sets). This stuff cures to be hard as a rock, clear, it adheres nicely to metal, and should provide the support you need. Don't get 5 minute epoxy because that isn't as strong and turns yellow.

Just be sure to carefully measure out equal parts resin and hardener and THOROUGHLY mix them. I mean mix them for like a full 2 minutes. Otherwise the epoxy may not cure properly and might come out tacky.

The epoxy starts to set up in about 30 minutes after you have mixed it, so you will have enough time to apply it to the hinges. After you apply it however, you will want to keep turning the glasses over in your hands otherwise gravity will cause the epoxy to sag. 2-ton epoxy is frequently used as a protective clear coat on custom fishing lures, and lure builders like myself make "turners" like this to prevent sagging. Obviously you're not going to want to build one but you can accomplish the same thing by slowly rotating the glasses around by hand for a minimum of 30 minutes, an hour would be better. After that is done just let it cure however long it says on the package.

Spiffy! Have you considered painting on an epoxy to seal it and improve structural integrity/longevity?

I bought this to coat 3d prints for watertightness and improved finish: "EPOXY RESIN CRYSTAL CLEAR 16 oz Kit. FOR SUPER GLOSS COATING AND TABLETOPS" https://www.amazon.com/dp/B01LWT156B and it seems like it would be ideal here.

It looks like there isn't any screws in that hinge. Whoever made this likely just used an adhesive.

This Devcon glass epoxy dries clear, and is pretty strong for glass to metal joints.

Whichever route you take, please post pics here. I'm interested in it myself

If you don’t find one these kits have everything you need, that would be a pretty easy repair.

Sand it, cut cloth to shape, resin on the board, place cloth, small amount of resin on top, let set overnight, sand, paint.

Sh*t happens but good luck. 👍🏼

Edit- just make sure you use epoxy resin and not polyester resin (if you take this route)

It’s pretty common. I’ve made belt buckles out of it.

I would recommend a 2 part epoxy.

JB Weld makes a steel reinforced epoxy that is very tough. It dries in 6 min in warm weather, and is totally hard in 45 min. Any other brand of similar epoxy would also work fine.

https://www.amazon.com/J-B-Weld-50176-KwikWeld-Reinforced/dp/B009EU5ZMA/ref=sr_1_9?s=automotive&ie=UTF8&qid=1487210197&sr=1-9&keywords=jb+weld+epoxy

JB also makes epoxy putty sticks, these are really easy to use, and work great.

Sand the two parts you want to glue with some 80-100 grit sandpaper, it'll make the bond much stronger than if it was smooth.

It's fairly easy if you are just replacing a standard plate with another standard plate. (Mounting on virgin boots, doing a short-forward mount, or things like that get a bit more technical)

Chances are you will need to drill new holes in your boot (often you can get 1 or 2 holes to line up, which is a good starting point). What you want to do is match the centerline of the old plate (kingpin-to-kingpin in the case of a non-symmetrical plate) with your new plate, and marking the axle and toe stop locations on the side of the sole is a good reference for the front-to-back placement.

I use a two-part epoxy stick to fill the old holes.

There was a good beginner's guide that was published in Five on Five a few years ago.

>aluminium welding the housing of the phone to a mount is a good idea though thank you

Etch up the mounting surfaces with sand paper (deep scratches with coarse), clean thoroughly with acetone and lint-free cloth, and then glue it.

Not sure what the best glue to use, but probably something like this:

https://www.amazon.com/3M-Scotch-Weld-2216-Epoxy-Adhesive/dp/B000WXHHTW/#customerReviews

That stuff is structural adhesive. Never used it myself, but it's going to be used in things like aerospace and automobiles to hold panels together. If you do it right they'd need a crowbar to get it separated.

I've been using this, works really well. And it's non toxic.

The inexpensive Whippeddog Handle at $6.00 and The Golden Nib Standard Silvertip Badger Knot at 20.95 or any of their other knots would be a good choice. You can glue the knot into the handle with Waterproof Epoxy - Setting a Brush Knot. I have several brushes with TGN Knots, they are great, soft tips and good backbone.

Yeah, this is recommended on another 3d printing thread I'm probably going to buy some and try it out myself :)

This was an awesome experience! The most important thing I learned was to make sure to tape far enough down the blade to prevent the epoxy from getting on the blade. :/

Not *exactly* what you're looking for, but I've had a similar situation with dry rot. There are wood reinforcing products that penetrate the wood (it acts like a wick) and restore integrity. Here's a starting point for your research: https://www.amazon.com/gp/product/B008DYN1B0 Here's something similar: https://www.amazon.com/System-Three-Resins-646697001380-Window/dp/B0015YLMUW

That is absolutely beautiful. Well done. Can I have it?

Maybe something like this product for maximum protection.

Do not use super glue. This will look like garbage, especially if this a plastic or acrylic surface. You can try applying drops of clear epoxy with a fine point as water droplets OVER a matte spray. If its over the spray then it should come clear again (All of the little cavities in the matte spray will be filled in assuming you do this in warmer temps).

4 gallons of this for $256. It wasn’t the cheapest I found but it suited my needed better. You could pour the stuff I got 1/4 inch thick at a time which was better than some other cheaper options which suggested 1/8th inch. I wasn’t about to do 8 individual pours 6 hours apart from each other.

I got this stuff off Amazon. This tabe, with the ~4"x20" trough took juuust under a gallon to fill. This stuff is good, git hotter than others I've used, but it cured super fast

Wow, that mixing paddle would be the trick. So you definitely think this is due to my mixing skills and not the product? For reference, this is what I used: https://www.amazon.com/gp/aw/d/B01LWT156B?psc=1&ref=ppx_pop_mob_b_asin_image

Also, it's been three days now but there is no denying it's less sticky, but still not quite there. I like to keep it a little above 70 degrees in my apartment, but I keep the windows open during the day and it's low 60's here and humid.

I feel like it might be a mix of both me not combining properly and the weather/climate here. I'm going to try a fan in a just a few and hopefully that helps a bit before I give up.

Pro tip: use this stuff called Quiksteel it's a epoxy/putty and it's exactly what you need and it won't fuck your lungs up when you smoke. Good luck!

This is the stuff I use the most for the kind of bonding your talking about. If you treat the surface properly it can do some amazing things. It can also bond aluminum, steel and stainless steel to carbon fiber.

*edit: forgot the link

you can use this shit to bond metal. it would be stronger than thin solder, imho. you can sand this when dry, with a fine sandpaper to a smooth finish. it’s nasty to work with, mixing it with the fingers, but it’s amazing stuff. rough up any metal surfaces that will come into contact with the product by scraping it on cement or a metal file or sandpaper first.

Food safe (direct contact) resin:

I would prefer silicone since resins have BPA in them. However, I have yet to find a food safe silicone coating. Silicone conformal sprays are more for water proofing electronics so food safety isn't a feature of them.

Epoxy. I had some extra PC-7 sitting around, this stuff bonds anything and everything.

Edit: looks like this doesn’t bond well to polyethylene so ymmv. Worked for me

Edit 2: scratch that. A bit of extra force and the adhesive popped off. Threw on a couple wood screws and hoping that’ll be the end of it.

I just tried it myself for the first time and was quite proud of the results...
Imgur
I used 30-minute epoxy to give me plenty of working time and applied just a tiny bit at a time to give it a chance to spread over the entire area I wanted it to cover. Use a toothpick to both apply and remove any excess epoxy.
Here is the tutorial I watched before I tried it myself.

I was speaking specifically of epoxy putty like this, this or this. Will that stuff not work because it might get too hard when dry? Would the silicone actually be better in this case?

Been using this JB weld epoxy without an issue, but I dont want or need instant seal but a strong seal: https://www.amazon.com/gp/product/B009EU5ZM0/

Like this? lol at the price.

Yes, get some epoxy putty, like this: http://www.amazon.com/Loctite-431348-Multi-Purpose-Repair/dp/B000BOB8P6 Used it to fix a very similar problem on my 7509HDs, solid as a rock now. Make sure to scrape the plastic a bit before you apply it so it binds well - wrap it around the broken area. I also painted it black afterwards, doesn't look too bad.

Edit: Here's a decent tutorial: http://www.instructables.com/id/Cheap-Fix-Bose-Headphones/

I managed to translate the brand as Cemendine (characters in the middle white strip) and while the green characters after the brand name (in black) were partly obscured by glare) knowing that "30" was part of it led me to
Cemedine 30 high super (30 minute epoxy).
Big tube (like OP's): http://www.amazon.com/CEMEDINE-minutes-epoxy-adhesive-CA-193/dp/B003F9VWXW
small tube: http://www.amazon.com/Cemedine-High-Super-30-15g/dp/B0036WCG56

/u/encaseme , I used the handwriting option to write out the Japanese characters with my mouse. image translate can be quite iffy. (I know Chinese, not Japanese).

Epoxy. I like Devcon 2 Ton. Bonds anything to anything. Just make sure you don't use too much; a little really goes a long way.

Ding All is overkill for this repair. This is very easy to repair with Epoxy putty that is cheaper and just as durable (if not more) with this size ding. You can get it from a paddle/surf shop for $12 to $15 a tube or get the exact same thing from HomeDepot or Lowes for half the price under Loctite or JBWeld. I keep a tube with me whenever I go out for emergency repairs to keep it water tight.

​

BluePlanet has decent video showing how to do it. Their Ding Stick is the same stuff as above.

https://www.youtube.com/watch?v=_5SPbD-te7o

​

After it dries give the area some sanding. Start around 150 - 180 grit then finish ultra fine, like 220 grit or higher. I've used it a few times on a yellow Naish board, then hit the spot with some Krylon and it's hard to see the repair.

​

If you are looking for something more cost effective than Sugru (which is great, but not cheap) you can try an epoxy putty.

Before you replace it, I would attempt to repair it using 2 part epoxy.

I am partial to the "JB Weld" brand, and this variety is perfect for a repair such as this...

here it is. You should be able to get it at any hardware store. It will work fine for what you want to do. I'd recommend you get the kwik set version.

I used this product. Looks like a million dollars, and is heat resistant, as well:

https://www.amazon.com/Countertop-Epoxy-Resistant-Resin-Gallon/dp/B00BISWFL0

use epoxy, they sell it on amazon for a good $8.

That is the link to the one I used in my down stem repair on my bong.
http://www.reddit.com/r/StonerEngineering/comments/2f2lpz/repaired_my_broken_downstem_on_bong/

I'm not sure what you're using, but a quick google search turns up clear Epoxy for less than $100 a gallon on Amazon.

Besides that, have you tried to negotiate a bulk price with the retail operations. If you're buying 100 gallon at a time, they can probably cut you a great deal.

If that fails, call some flooring companies and see if they have any leads for you. They are the only guys I can think of who would need Epoxy in those quantities.

Why not just use some 2 part epoxy. It will harden clear, can be cut and shaped just like wood and will bond to almost anything.

You could always coat it with clear food grade resin. Here is on I found on amazon.

Edit- Make sure you read the labels to see what kind of food contact it can have. Some things are fine for dry food but not liquids.

PETG is actually food safe, but the lamination lines will trap food that will spoil.

This epoxy resin is food safe, as are several others

Maybe dip them in epoxy like this stuff

hmm might make the paper too floppy maybe spray and then brush on some epoxy.

Yup, available at your regular auto parts stores like AutoZone and Pep Boys.

I'll take a look. I toyed with the idea of selling cookie cutters on Etsy earlier this year, but got super depressed midway during the design phase and never made it to sealing. I got close to a finished model for a few of my designs, but found the gaps around the edges discouraging.

Something like this should work, but you can probably find a cheaper version at Michaels or somewhere.

I second the PETG idea, though. PETG is usually food-safe (we've got a PETG neti pot we bought at the pharmacy, and that goes in your nose), and it holds up to higher temperatures better than PLA so you could totally throw it in the dishwasher.

The other thing you want to be careful of is the brass nozzles might sometimes leach bad chemicals into your cutter. You can get stainless steel nozzles, but they're a bit pricier? They'd be a lot safer, though if you're extremely worried you might want to do the old "into a pot of boiling water" trick to sanitize them.

Slow-setting epoxy is an alternative. This one has been serving me well.

Drill some holes on each side of the broken part and file the plastic down to be thinner. Get some 4000psi+ epoxy like this ( www.amazon.com/dp/B009EU5ZM0 ) and shape it to how it should look. Make sure to get it through all the holes you drilled so that it has places to hold onto for strength. Wrap it in wax paper and clamp it to hold the broken part together.

Once it dries just file it down to size.

It seems like you'd need a pretty low viscosity product that could be poured down into the voids. I think most of the rotten wood repair products I've seen are much thicker, more putty-like in consistency.

Although a lower viscosity product might just seep and run through the cracks and out the sides unless you contained it somehow . . . maybe a couple of tightly wrapped layers of that stretch-wrap used by movers/packers?

This seems like it might do the trick?

Do you mean that the frame is actually cracked? I just managed to glue back a similar frame with J-B Weld 8276 KwikWeld Quick Setting Steel Reinforced Epoxy if that helps. You can see the machine here while the product is setting.

I haven't tried to pull hard on it after glueing it, but so far it seems to hold.

I just googled food saw epoxy and this one here is supposed to be FDA compliant.

Why did the chemical engineer say he wouldn’t want to eat out of anything with epoxy?

Get a can of bud light and put it under the monitor that is sagging. Then put some epoxy around that joint and wait for it to set.

A hardware store. It's this stuff. Not expensive at all.

You can get Cemedine epoxy on Amazon, but there are lots of 30 minute epoxies out there.

JB Weld is my go to for epoxy or adhesives: https://www.amazon.com/J-B-Weld-50112-ClearWeld-Quick-Setting/dp/B009EU5ZM0

I've used epoxy from the same syringe probably 5 or 6 times without issue. Note that you will have to mix the stuff from both sides before use - this is likely why it is reusable.

Maybe look into JB weld, or some kind of epoxy?

You may be able to fill it with epoxy. Find a food-safe one. https://www.amazon.com/CLEAR-GRADE-Epoxy-Resin-System/dp/B01J16MYSE

If it's a metal break, you might be able to fix it with some JB Weld.

You mean the little keyboard feet that raises up the back?
Just repair it

Not just any epoxy. Should be good grade. And if you’re using the glasses from alcohol or acidic drinks, I’d be careful not to use them too regularly, as (I’m not 100% certain) it may degrade the epoxy a bit, and it’s probably not a great idea to ingest those particles.

As everyone (including OP) has pointed out, this is not the best choice. According to the official site (http://www.loctiteproducts.com/p/sg_glass/overview/Loctite-Glass-Glue.htm) it is not recommended for use above 176°F.

If you absolutely need to make a repair/weld, I would suggest using QuikSteel. It's rated to be safe up to 500°F. I would avoid using it within a few inches of the bowl.

Get some JB Kwik. Sets up in 6 minutes and cures in 6 hours. Nothing beats good ol' JB weld for gluing stuff to metal.

Victorinox SwissTool. Like a leatherman only much sturdier.

QuickSteel epoxy. You knead it. sets in second. I've repaired broken engine cases with it on the side of the road. https://www.amazon.com/Blue-Magic-16002TRI-QuikSteel-Reinforced/dp/B000FW7UOM/ref=sr_1_4

This question doesn't have enough information in it to provide any type of answer beyond a list of handguard manufacturers so I'm going to assume no budget and no mounting preference.

The pegs are plastic on those right? If gluing them doesn't work (since the peg will lack lateral stability at the break) you could drill out the broken pegs and use epoxy to put in replacement loom pegs. They might be a different color and shape, but at least you could still use the loom and since the base of the peg would be set in epoxy and surrounded by the loom body, it would have much greater strength against shearing forces.

Alternatively, you could use drywall or self tapping metal screws to just screw into the spot where the broken pegs are. Pre-drill the hole with a bit that is just a tiny bit smaller than the screw to prevent splitting the loom plastic.
