CA as pore filler?

Discussion in 'Luthier's Corner' started by wilser, Nov 2, 2005.

  1. Hi, I was feeling lazy yesterday and didn't want to mix up epoxy (which I use as a pore filler) for such a small job as finishing the headstock veneer plate and a small piece of wood I used to cover the neck extension into the body (as used on my designs), so I used some CA (medium viscosity) as a pore filler and it worked great! I have a nice flat area that was easy to apply and sand. Nitro is going over this, anybody got any comments on this?

    I've got a question too actually,

    Does it take a long time to dry? Or do you have to be super carefull with the thing for a couple of hours until it dries?
    Or do you spray some of that CA accelerator stuff to it?

    How is it to sand back?
    Is it a pain in the @ss like epoxy, or easier ?
  3. well, I can answer those:
    it takes quite a bit longer to cure when it's in big quantities, it's not like your spreader tool is gonna stick to it. I'd say about 1-2 minutes to get sticky and about 5 to completely cure. I used a small brush applicator and didn't have any problems. I didn't use any accelerator.

    It's a joy to sand! it's not at all like epoxy where it loads your sandpaper in a couple of strokes. I think I used a hard brush to clean the sandpaper every 10-15 strokes or so. The sandpaper I used still feels like it's got much life on it.
  4. I once carved a wishbassesque bridge piece from a small piece of wood and used CA to give the soft wood I was using a bit more stability...

    I found that the same thing...it filled the grain readily and was quite easy to sand...

    CA dries a bit more "crumbly" (if that describes it right) than epoxy...as a result, i think it pulverises and flakes away from the sandpaper more easily, whereas epoxy tends to stick and load up the paper...

    I use it to fill un-even areas in spalted tops. I use lots of thin coats and sand in-between....t

    I've been using CA on headstocks for pore-filling for a wwhile. I don't recommend it on larger areas, like bodies, but only due to the fumes. IT works well for me, I usually only use it on areas that will get an opaque finish. THe guys are right, it sands much better than epoxy and it leaves a nice satin finish.
  7. Fumes can be a problem, do it in a ventilated area and get a fan on it (helps it dry quicker too) other wise you will be crying like a baby.

    I used to use CA for my inlays as well but it can leave shiny ares on the wood it has soaked into around the inlay, this is only a problem if its on a un-lacuered area.
