I was wondering if I were to use a sanding sealer or a laquer on a pen and then CA would the CA work over those 2 finishes, will they prevent the CA from sticking or will it come off later on???
My main idea is to seal the wood first and then apply the CA, any ideas??
Thanks and aloha.

Chris, I think the CA alone would seal and no need for any other sealer prior. Not sure how long the CA would stay on the sealer, may be just fine. Probably depends on the quality of sealer, making sure it is cured fully, temp, humidity, alignment of stars, etc. Like I have seen on many posts........"try different finishing practices until you find the one that works best for you". Myself, I just CA (Thanks to Ken Mayes) and sometimes BLO.

Kalai,
Most sanding sealers will accept the CA after the blanks has been fine sanded, but in reality the first coat of CA will do exactly what the sealer will, only faster. The sanding sealer prior to CA, regardless of how many coats of the sealer you apply, is not going to make the CA any glossier/shiner, that will depend of how you apply the CA and what you use with it BLO or other.

Make a few test samples just by rounding some less interesting blanks and apply various combination of finishes, this normally is a very good way to find what works well for you, or the one you like most.

Good Luck

Cheers

Lacquer goes over CA beautifully. Liquid CA is a great lacquer remover.

As everyone else says, a couple of thin coats of thin CA will seal the wood better than any sealer and won't "muddy" the grain like some sealers do.

Thin CA goes on all my wood blanks first to seal the blank up. Working on medium and thick CA for finish coats. Right now I do 6-8 thin.
Chris the sierra I sent you was 7 thin CA finish
 
There is a great video on dealing with CA in the library (by Russ Fairfiled). He uses thin CA for closed grain woods and medium for open grains. Take a look.
 
Hi everyone, thanks for all the replys, I was thinking of using the CA finish on some of my bigger bowls and that is why I was thinking of sealing the grain before putting the CA on, I figured it would take a lot of CA to seal the bowl so I thought of using the sanding sealer and then the CA, what do you guys think???
Aloha.

Chris --

CA glue on bowls can cause some blotching as it goes into the end grain or bruising of the grain. Most have better success with a shellac seal coat first Cherry and pine are famous for blotched finishes.

Clear dewaxed shellac is about as foolproof as possible, and it may not avoid all blotching. If you need CA as filler -- try the thick and then shear scraping to level the surface after the shellac.

As always, try it before you are at final stages and you can cut it away.
