ok, got the floors on forkedup cleanded up and repainted, looking good so far, i just went to resin the floors (this is my first time doing this), i followed the directions on the resin/hardner, it says 10 drops of hardner to 1 oz of resin, seems like alot but what do i know, i mixed up 16oz of resin and put 160 drops of hardner in it, mixed well and went to applying to the floor, in about 3 min the tray i had the resin in was jelly, can no longer apply, is this right, is that all the time i have to apply it or did i miss something with the instructions, i did read them again, pleaaaaaase help, i am trying to get a coat on the floor tonight ;D

Reduce it with Acetone......... Gives you more work time cause its already hot outside ;)

What he said. Or try 60 drops for every 8 oz.... our hotter temps make it so you have to spread the stuff FAST
And if you mix it in smaller amounts, like 4 oz at a time..... it makes it easier to spread without it kicking so fast.

You can also reduce with MEK (methyl ethyl ketone) and this will buy even more time (evaporates a little slower than acetone) if its a polyester based resin.
The hardener amount sound high, what products are you using, if you dont mind my asking?
-
My guess is its the Bondo brand , and the hardner sounds about right... I made it in 12 oz batches any smaller and it will take forever......
Also it helps if you have another person to help you out....(wifey) ;D

If it is hot outside, put the resin in the frige for a bit, dont let it get too cool though, the only draw back to doing this is it sometimes cures a little "cloudy" but does buy more time, also if the hardener you got is old it will do exactly what you explained, the peroxide in the hardener starts to breakdown do to being photo (light) sensitive, (ever wonder why rubbing alchohol comes in a clear container and hydrogen peroxide comes in a brown container?) hardener is cheap.......
If the resin "gelled" and stayed that way for a long time before hardening, I would say definately time for more hardener......The Bondo brand stuff has a chemical in it that changes color when the hardener is added, did it change color (like yellow to green, or brown to blue)?
This is why I use the epoxy crap, you change the hardener for the aplication (almost idiot proof)
Good luck!
-
the brand is evercoat, got it from one of my suppliers at work, it did change color a little when i mixed it, i will try a use a little less hardner per pw and work alot faster ;D, the small part i got done looks good.
-
the help factor ain't gonna happen, she's pregnant and watching the boy, all he wants to do is help and as much as i love him, all i need is a 2yr old runnnig around the garage while i am doing this ;D

Evercoat is good stuff, its prbably the waxed stuff (finish), so you can play around with the ratios a lot. The laminating resin is a little more tempermental.
-
it is amazing how fast you can work when you don't know shit about what you are doing or how much time you have ;D, got the first coat on, will let that sit overnight and do a second coat tomorrow night, first pic is before, second pics are after the paint.
-
couple more, before resin, last 2 are after the first coat of resin
.
.
how is everyone spreading this shit out, roller, brush ??? i don't know if i am doing it right or not, but what the hell >:D
-
That is turning out really nice!
I like it!
-
thank you ;D

2sav, Acetone is for cleaning up, you add Styrene for thinning and work time lengthening. NO MORE THAN 10% to 20%, and I would say 10% max. ;) Greg

Once again, i call BULLSHIT........ read a can of Acetone.
Yes it does work well for cleaning ;)

OK, so the can says thinner but that is the wrong product to use with polyester resin. I don't care what the can says. If you want the resin thinned for flow and penetration you use STYRENE MONOMER Polyester Resin Thinner. ::) I get it at Tap Plastics and it's not cheap.
-
Well acetone is cheap and that's why I use it..... and it works ;D

Don't tell him that, you have to be politically correct to fiberglass shit and use the expensive shit :screwy:

The biggest thing i hate about resin is the "drops" bullsh@t....anybody have a better ratio in ounces?
-
Honestly I mix resent just by eye most of the time, depending on how hot it is etc.... but I've been working with fiberglass for a while

try http://www.sunrez.com/ we use their products here at my company. its uv cured resin. if your indoors/garage you have an infinate work time. once uv rays hit it(the sun or special lights) it cures in about 45 seconds. doesnt matter if irs 120 in az or -10 in alaska, this stuff works!!!

that would be awesome...I will have to look into it!
-
wish i had known about that stuff before i bought this and started working on it already :banghead:
-
keep in mind when your using sun rez (if you try it) keep your work area out of direct sun light. also ive made my own UV lights for around $100, where a sun rez light cost $600 and up plus shipping. if you try sunrez PM me and ill let you know how to make the lights.

well started round 4 with the floor fri evening, the black looked ok but as soon as the resin hit the white it looked dirty and muddy, sanded the resin back off of both colors (black was ok but not good enough for me) reshot colors, reresined the black and getting ready to do the white (a diff way) hopefully this will be it and i will finally be done with the floor and i can start assembly again.
-
done :banghead:
see "its home" thread for more pics ;D

what if you don't put enough hardener in the resin, what will happen? I just did my seat mounts and it's not real hot out and it doesn't really seem to be kicking off. Will I just have a mess of goop to clean out or will it eventually harden?

If it never hardens, then you'll have to scrape it up, and clean every bit of goo off.... but I've had a few occasions of resin taking a few days to dry.... the longer it takes to dry the stronger it is.... so give it some time
-
Thanks PW. I was getting a little worried about it. I will wait a couple of days and see what happens before I do anything.
-
mine took a little over a day before all the tackyness (sp) was gone
-
It hardened up.
