What... a doof!

[Musicinabottle]

I can't believe I did this. I recently bought a fiberglass resin kit, which was a half gallon of resin, and a half gallon of hardener. I've never screwed around with fiberglass, but plunged ahead and poured out some resin in one paper cup about 1/2 full and poured some hardener in another paper cup same thing 1/2 when I realized that I had to mix them in the one cup, so I poured back in to the near full bottle of resin, the resin cup until I had about 1/3. Then without thinking........ I....... poured back in some of the hardener, into the resin bottle. I just left the bottle there, didn't mess with it or move it, nothing. I figured that since both bottles are near full, and I only dumped back in about 2 table spoons, I figure the actual site of contamination in the resin bottle will go off and harden enough to where I can surgically remove it tomorrow morning. Or is it totally toast?

Toast.

I'm interested to see how this comes out.

I have only used the west systems in bulk and the ones I have use the pump.

 

[Musicinabottle]

Toast.

A little bit on top of a full bottle will do it clear to the bottom huh? Dang.....

Science experiment. ������

Let us know in a few days!

 

[Musicinabottle]

Yes, I'm hoping since I didn't move it at all, that the hardener will just sit at the top, and because it wasn't mixed in essence, it'll just harden around the edges. Then I can remove it from the bottle and use the rest.

Whatcha gonna make with it?

Well, it all depends. If it goes to **** on me, then it's going to be high density filler for the garbage can. If it survives then it will be doing some fiberglass repair on the inside of my box truck!

The problem is that some if not all of the remaining resin probably will be contaminated. working with Fiberglass is pretty forgiving, but you do want whatever your fixing to come out correctly. To much hardener, and it will be brittle and set up fast, to little and its going to be a messy cleanup. I fixed a lot of Surfboards when I was a kid and "Experience" is a great teacher, unfortunately it shows up right after you need it. Good luck with your experiment. As always, just my .02.

If the components are meant to be used half and half, it must be epoxy resin, as regular polyester resin only uses a tiny amount of catalyst (hardener). Either way, it's probably toast.

One more vote for West system with the pump.

 

[pamike]

It wont ruin the entire jug, but you will have a real mess trying to get it out if the blob of hardened stuff is big enough to plug up the can opening...

 

[K13]

As mentioned it is not polyester resin if it's a one to one mix ratio. If it is polyester you probably put enough hardener in to catalyze the entire can as it would only take about 40cc's of hardener to do a half gallon.

 

[Musicinabottle]

No, it's one to one ratio. I'll be going out in an hour or so to see if the whole jug went off or if it remained isolated like I'm thinking and hoping it will do.

Its likely toast and will eventually set up. If you want to get a decent job on your repair project, toss the resin and start with new. You will find that the catalyized resin will become unevenly lumpy making it only good for using with talc or asbestos as void filler.
I've built lots of small boat and used multiple barrels of resin but would not try to use a gallon or two that is compromised. Toss it.

This.

Well... I had a few gallons of some vinyl sealer and CAB Acrylic lacquer that were way over age. Unsealed, but like 7 years old. (Shelf life is 2 yrs)

I was going to finish abut $8000 dollars (and 150 hours) worth of cherry cabinets, dovetail drawers, doors.

Opened them up. Didnt like the look of the sealer, had a pink tint. Definitely bad. the lacquer looked OK..... sprayed OK, seemed to dry OK...but...


I spent $300 on new materials.

Hopefully whatever you use it on isnt critical nor expensive.

 

[Duker]

This.

A "second" on this.... even if it didn't totally harden the rest of the jug if you use it and it doesn't set you will have a nightmare to clean of a gooey mess that only partially hardened.

 

[Falcon67]

Toss, buy more - it's not that expensive in the first place.

 

[Musicinabottle]

So I went out there and frankly, it looks just fine. It never went off in the jug, nothing. Just for the heck of it, I mixed up another batch and dis a sample spot on some plywood. I'll look in on it to see what happens. Now, I might not have actually dumped the harder in the resin jug, but the resin jug level is about 1/4 inch higher than the hardener. It surprised me that I didn't at the very least have a hard glob in the bottle. I'm going to order another kit if my test area doesn't check out tonight.

 

[K13]

What kind of resin is it?

 

[Musicinabottle]

It's Max Bond. It seems like a great product thus far. So I went out tonight and my samples set up and are plenty strong. I went to scrap it off with a painters 5 way and it took wood with it. I believe I got lucky.
