Plug Work - Mini Issue
« on: December 30, 2014, 12:07:52 PM »
I have been running into an issue with plug work.  Not sure whether it is related to the plug cutter or the curing/mix of the plug.

I try to be very careful about the ratio of plug/hardener and gently mix to prevent air entrapment.  Temperature in my basement was a little cool (around 68F), so I allowed a full 24 hrs.  The plug inside the dam was hard, no air bubbles on the surface.

When I cut down the plug, there was a very rough texture:

After finishing up the plug work and cleaning up the ball, the plug isn't aweful (besides the color match :P), but there are a few tiny "pits" that show up:

This one is going to be redrilled back through the plug material, so not too big of a deal, but otherwise, I think it should be possibly to do a little better job and eliminate the pits.

Has anyone else ran into this before?  Am I missing something or missing a critical step?  Any suggestions to try?

I'm using the Pro's Choice plug material from Innovative.

Thanks,
Scott

Let it set up longer.  You will probably notice that these plugged areas will still shrink some.  24 hours just isn't long enough when it's that cool.

The picture of the plug cut down before finishing appears normal. Usually bubbles are caused by the plug curing too fast for the air bubbles to rise out of the mixture. Try mixing the plug slower and/or coloring on the darker side so they aren't as apparent. You should also be filing the plug with a bevel knife after cutting it down. If these don't help try switching brands of plug. I've always had good luck with Brunswick's plug (better for lower temperatures) and Ebonite's Power House Everclear plug (be careful as this can get too hot too quick if mixed really aggressively.)

Hope this helps

I'm guessing you might need more time and/or heat for that to cure. If you deal with rooms that are difficult to keep warm, I might use a heat light for the first two hours of plugging a hole.

Do you use the pumps or measure with a measuring cup?  --  JohnP

Yes, measuring cups.
