Filling a crack that was repaired 20 years ago and covered with a tar like liquid. Will the A/B epoxy mix stick to this?

my best guess is no.i would try scraping off as much of the tar substance as possible. i had paint that had been applied to my wall, and i spent a lot of time scraping and sanding it off.

I would not think so you would need a two part epoxy like JB WELD that is what mechanics use mix the two together evenly and apply with a toothpick if it is a small object add epoxy on both ends of broken pieces practice on something first then you will know just how to make your repair.

yes within the limits of its strength. it won't hold pressurized water or air forever (plumbing or scuba). i would give it 48 hours or so to cure. the crucial point, as with all adhesives, is proper lamination. the surfaces to be glued must be strong and clean. good luck.

I would say yes. I have used it on a fiberglass sailboat and it stuck like iron. Warning. Mix a good dollop When you try to mix a tiny amount it doesn't harden well. It is a 1-1 mix which is easy but the cure time is long which is typical with strong epoxys. If I were you I would clean clean clean the crack and then clean again with acetone. Then use this or even better ( but more expensive). Marine tex white epoxy. Good luck.

You could build a barrier and put wax paper between the barrier and the epoxy. The epoxy won't bond to the wax paper.

Sure, the two ingredients are only activated when mixed together, so the epoxy won't harden in the tube between uses.

Seems to hold ok on plastics if allowed to completely dry (at least overnight). For things like stone and metal it doesn't adhere so well. Agitation more so than water itself is the problem (such as rinsing the glued item under running water). Probably better off using 4-minute epoxy, testing an inconspicuous area first to make sure the adhesive doesn't dissolve the items being glued.

It's a real thick paste so not sure how good of adhesion you would get on a rough surface. It's not going to "wet" like super glue would. Good for filling a hole or something, but putting a cracked piece back together? You would have to make sure you rub it into both surfaces real well before putting pieces together.

I definitely think you could, and that you'd be very pleased with the result. Some tips: make sure your surface is as level as you can get it before application, make sure you mix the heck out of the two components, like ad-nauseum, when you think you've mixed enough, mix it more. I found it useful to have a heat gun handy during application. If you see bubbles, gently hit them with the heat gun and they'll come out. Be careful not to burn the epoxy compound though!

It will initially adhere but this is a relatively light duty sealant, not a heavy duty caulking. Your blue tarp application suggests possible unavoidable movement or required flexibility that may be beyond this product's long term capability.

probably not. It gets its strength from being wrapped around itself. The epoxy bonds best when wrapped not applied in a single layer. Seek a wall crack repair!!!

Probably depends on the surface area of the crack/break. I would personally think that a Cyanoacrylate glue would be better for ABS. Perhaps you could use some Super Glue on the crack/break, then use some JB Weld to build up the external surface, if permissible.

I used it to seal cracks on my driveway and it has stood up to the elements for at least five years. I think that if you prep the area and apply an even coat that it would hold. It stays rubbery when dry. You may want to try it on a small obscure spot first.

It is hard to say since it sounds like in your case the epoxy would be weight bearing. What I can tell you is that it worked great for patching a rusted exhaust pipe flange(about a 1/4" gap). I no longer have an exhaust leak and patch has held for a few months now

It is not a glue -- and glue/adhesive does not stick it very well -- you might take a look at an epoxy, Bob Smith brand is very good.

It seems to mix fine, However I would try to avoid mixing old solder. I use Tech Spray No Clean Desoldering braid to remove old solder. The quality of the desoldering braid does matter, Do Not use Radio Shack or generic brands they will only result in 4 letter words coming out of your mouth.

I don't think it would. It dries like rubber.If I were you.I would get a cement crack sealer that dries like cement.This levels off.But it seeped into the crack after a few weeks.Get something that dries like cement.
