"Primer not sticking to resin terrain piece issue" Topic

Hi,

I have this great 15mm german radar station I purchased a few years ago and am now painting it up. But…

Cleaned it with dish soap and water and used a toothbrush to do some scrubbing. Primered it white and in quite a few spots the primer pooled. Nothing wrong with the primer (rustoleum) as I primed some russian buildings by Kerr and King with it and no issues. So got off as much paint as possible and cleaned and scrubbed again Same issue but a lot smaller.

What can I do to clean it right the first time. I'll be cleaning it again later, frustration level on the rise and do not want to fling the piece across the room. Hulk no want to destroy lovely terrain piece.

Any suggestions appreciated.

Thanks

Wash with coke, vinegar or lemon juice, then wash again with soap and water. The alkaline soap isn't working, so try something acid. It's worked for me in the past.

Rustoleum primers tend to be "wet" in my opinion. Try a grey "dry" primer like PRIMER from Michael's Crafts or Armory Grey Primer…I think the above suggestion will work too.

If it not the model release and washing with Coke , vineager lemon juice , simple green does nor help . check the piece for bad resin mix . Wrap in news paper set in sun and see if it leaches ( grease stains in paper) . If it does there is not much help for it .

Thanks guys. I'll clean with vinegar or coke and then prime. If that fails, I'll do the bad resin mix check. Really hoping that is not the issue.

Once again thanks for the cleaning tips.

I had a bunch of terrain pieces that caused the same dramas, due to the release agent used (and also I suspect cheaper resin).

Auto primer is your friend, go grab a can and you'll get the priming job done. Any time I know I'm dealing with either not great resin, or there were crud release agents used in production, out comes the auto primer!

I've found cleaning not to be that effective on terrain pieces as the release agent gets absorbed into the resin, and no amount of cleaning will deal with it.

McWong73, two things.

One thanks for the advice and two (way off subject), I used to run a beer and wine store quite a few years back. Was invited to the local Hop Scotch show (beer and scotch) and a rep from a company that sold a wide variety Scotches who was Chinese introduced himself to me as McWong (have forgotten his first name). He was wearing a kilt and talking with a thick Scottish accent. He informed me that the McWongs were a far eastern clan of Scotland and their favourite food was Kung Pao Haggis. He made beer come out of my nose. It was f'n brilliant.

Your screen name just brought up that memory and a smile. Thanks.

LOL!
Try Cockaleaky Wonton soup sometime, beats the haggis.

I have had good luck with washing plastic figures in denatured alcohol and then primer with gesso….

If the resin mix is bad, leave it outside in the elements for a couple months. That has worked for me. I have also tried baby power sprinkled on the model with okay results to absorb the resin mixture. Leave it on for a week or two and then wash off. I had to leave one tank outside in direct sun for a year before it was usable.
