General Discussion

Hi Guys,

I need some help Bad!

I Just glossed my first pinline job, They were beautiful. Until I glossed…

what step did I miss, Very iritated with myself right now!

Pinlines were Dark Blue/Black Resin (sanding)

Glossed with Kokua’s mixture. 24 hours after the pinlines were completed

Help Please

Howzit Nostalgic, Strange, after 24 hours the pigment pins should have been totally hard. I suspect it was the styrene in the mix that caused the bleeding. You may have added a little to much and since styrene is a resin thinner it would disolve the resin pin. I have never had this happen to me after to many pin lines to count. These days I use india ink for pins and the styrene doesn't affect it. What is really confusing is that when I do resin pins I lay down the gloss right after the resin pins kick off so I don't have to sand them, it's an old trick but it's always worked for me. Sorry about the bleeding.Aloha,Kokua

Kokua,

Thanks for getting back to me, Mybe next gloss i’ll try 5% insted of 10%. Or try hitting the lines with a fast hotcoat to make sure they are sealed up tight before I gloss.

Thanks again,

P.S. I love your mix

Cody,

I had problems with “bleeding” of resin pinlines before and, in my case, I think it was due to not mixing enough and the bleeding was caused by “raw” pigment… I now do the following and have not had any problems since then:

  1. Make sure and completely mix resin and pigment.

  2. Strain/filter resin-pigment mixture

  3. Catalyze resin-pigment mixture.

RandR,

Thanks, i’ll give that a try on my next board. By mixing the pigment better, and a little less styreen I should be able to eliminate the problem. Thank goodness we had some swell today, I needed to release a lot of tention.

Later,

After it sets you might try a light swipe with some acetone on a rag. It usually gets any residual pigment off… hopefully without erasing your pinline. If the resin and pigment is mixed thoroughly and catalyzed on the hot side, you should be alright.
