Thank you for your help, will get some more resin ordered tonight then and hope the peel-ply comes off ok. 

Give the tacky area a key with sand paper to remove as much of it as possible, clean it then you can overcoat.

Cool thanks for the advice. I can't just go over the old fibre either though can I?

Small batches can be difficult to get the measurements right, especially if your scales are only +- 1g.  Using jewelers scales can help improve accuracy.

You will need some fresh resin to repair the damage.

I suspect it was wrong mixture even though I weighed it out. The scales must be really wrong because 50g of resin was well over half the bottle.

IT sounds like you have 2 issues here, wrong mix ratio and also running out of pot life resulting in exotherm in the pot.

The first issue can be resolved with accurate measuring and mixing of the resin and hardener. 

To avoid exotherm, mix a smaller batch size so you use the resin up before you run out of pot life. 


For Rapid Repair Resin to still be tacky suggests a poor mix ratio and/or poor mixing.

Can't put hardener over the top, that will make it worse. It really needs to be mixed properly. Hair dryer won't work, it won't get hot enough. A heat gun might but it will take you hours, it's going to need a long time at a consistently elevated temperature. Could possibly put it in a box with a heat gun sticking in the side while you watch TV for a few hours, but that's obviously a risk. 

Thanks for the reply, woke up this morning and one skate is great! The other is still very tacky. I can't really bake them so hoping to run a hair dryer over the top of them for a while.i can't even get the peel-ply off as it's that tacky.

Really really have to make sure your mix is accurate when you're working with epoxy, especially when you're doing such a small amount. You should always try to be within 1% of the mix ratio, so at 100 grams if you are more than 1 gram out either way then it can cause issues depending on how sensitive the epoxy is. If in doubt, it's always better to not proceed - no fun at all to clean up partially cured epoxy.
