"Removing stickiness on resin" Topic

I recently purchased a Nayk Spider Mecha from West Wind. The casting is very nice but significant portions of it are covered in a sticky residue. I've worked on several other resin projects, and this is the first I have ever seen with a substance so tacky that it grips paper towels when you try to wipe it down. I gave it a bath in warm, soapy water and the stickiness remains. I tried several applications of Goo Gone and the stickiness still remains.

Has anyone else had this problem and what suggestions do you have for removing the stickiness?

Sounds to me like the resin didn't cure properly. If it were me, I'd be thinking of returning it for a new model.

Alternately, you could try priming it – if the primer coat covers, then the stickiness problem is solved…

Return for another model. I had this with a resin senic that I could not return and had to chop off the bad corner and make a ruin.

I had this issue with some terrain I purchased a few years ago. Return it, don't bother trying to prime it as it will take multiple coats over time to finally get enough primer onto it.

You may be able to use gesso, but I'm specualting here.

you will never cover it succesfully it will still bleed through.
i made a duff batch of resin few years ago and the jagdpanther model is still bleeding through the paint.
i would send it back and get a replacement one.

If it's bondo-type resin, try acetone.

It's impurities in the resin mix seeping out, usually the result of a bad mix or filler. Happens sometimes with certain types of resin, and can take a long time to clear up on its own. You can accelerate the process by leaving it someplace warm and dry and exposed to air (ie a nice sunny day outdoors, but beware of it getting hot enough to soften) and by cleaning it with acetone as Klebert said. The stickiness will probably come back several times over a period of days or weeks but it should eventually stop seeping – the worst case I've ever had took two months of airing and cleaning, but it did clear. Don't prime the piece until it's cleared – the more exposed surface the better – or clean the primer off the affected area if you have (it should slough off easily anyway, the petroleum residues prevent it from sticking right).

It's also possible to burn the stuff off in some cases by using a lighter to start it, but it's not great for the resin, it probably gives off toxic fumes, and it's an obvious fire risk. Looks pretty, though. :)

return it. your resin casting was made with insufficient surfacing agent. this is usually a parrafin based additive that allows sanding, but also prevents the sticky surfaces.

Apparently it was one he won from us as sealed box ebay item. We had three (cleaned out the local store's stock last holiday season) the other two of which were fine (did one ourselves, and the other sold locally and was opened in my presence. Bad egg in the lot – but West Wind will have to replace it, I'm fresh out. Doubt they'll give him a hassle about it, every resin caster has to replace kits now and then.

I'll reiterate the caution against actually setting it on fire, though. :)

Coat it with Talc and then see if you can prime it with a good spray primer.
