How do you get 'Not gone off' Epoxy off
« on: December 13, 2011, 12:01:47 PM »



Says it all really.

Yesterday I mixed the two bottle epoxy to secure the hand rail to the fibreglass bow and taped it down.

This morning it's the same consistency as when it was made. The temperature in the Garage is 4 degrees C at the moment but was probably that or less during the night. It was old stock from last year.

I peeled off the tape and have lifted the rail  (with rubber gloves on) and the stuff is running slowly down the hull and is still on the back of the rail.

My question is   'What chemical can I use'  to remove all traces please, and will a new mix adhere satisfactory to any residue ?.     <:(

Answer in two parts:

1)  the solvent for Epoxy (uncured) is pretty near any solvent.  Alcohol (meths) is porbably the easiest, but acetone, cellulose thinners and lots of others should work

2)  given the temperature in your garage the Epoxy is just waiting to cure.  all chemical reactions double in speed (we used to be told) for a 10degree rise in temperature (cant remember C or F :(()
so mop off what you don't want with solvent and warm the whole boat to a very warm room temperature and she should set happliy

Thank you the info Andrew.

I tackled it today and you're right.  It is runny and tacky. I just kept wiping away and it cleaned up reasonable.

As it's an isolated section and I won't need to go there for a while, I shall leave it be and let it dry.  I went down and read the can and it said it must be 70 degrees F to cure.  Must wait for the summer.

I've continued my blog on the Gry Maritha page and have photographed it.

Hey Ho,  thank goodness for Model Boat Mayhem.   :-))

Use a hairdryer on it at low setting Ken.

Ken,
glad the solvent worked

Colin is of course dead right - a little applied warmth will do the trick.
My habit is to use a moskito killer (the hot plates that you used to put pellets on) and place the boat over it and then cover all with a big cardboard box,  Its only a few watts but it raises the temperature enough to speed the cure

 - other folk use a 40W incandescent buld carefully placed as a heater

Hi Colin

I did wonder about this but thought I might have to run it for hours.  On thinking about it I suppose it really needed a kick start, say for half an hour then let the process take over.

cheers

Not even as long as that, just get it warm - and bring it indoors.

Tell here the smell reminds you of "permanent" hair setting chemicals...  ok2

Oh, a lightbulb and an enclosure also help to keep a small area warm, but best
not leave it unattended all night. I had one set up that could keep the interior of a
box over 48C using a 100watt bulb.

I'm really surprised buy this and some other posts lately.

We live in a world heavily influenced by Stealth & Hafety...... Have risk assesments on almost everything we do .... (blimey, i even heard a Scottish Minister talk about risk assesment in banking practices ... and yet we still , in our wee hobby ... where its us against the chemicals ... don't read instructions .....

Now call me old fashioned ......

Hey John - no shed sob storys please <:(. I'm sure you would be living in that lovely big car of yours - anyway if fuel gets much dearer then that's all it will be good for.

Epoxy doesn't smell, but the fumes are not good for your health either, I use it in a well ventilated room and have a small (computer)fan blow the fumes away from me.
So far, so good. (Working with polyester professionally for a few years has made me allergic to the stuff, with epoxy I don't have any issues yet...).

Funny the way our other halves complain about the smells our hobbies make. Yet we never complain about the smells of baking cakes, coffee brewing, dinner in the oven, fresh flowers etc. Life's not fair is it?

i know this is  old post but after reading this i thought i would ads some info, the reason why women can smell things that dont bother men is because they have twice as many smell receptors as men!

Yes, they are superior to men in oh so many ways - or so she keeps telling me!   %)
