Lacquer Over Ca(?)

Recommended Posts

While experimenting with small holes is wood, I filled some with a drop of ca glue, sanded flat then sprayed a couple of test coats of Lacquer over. Sanded flat with 240 paper. The next day I noticed where the ca filled the hole, there was a slight hump. I sanded flat again and applied a few more coats. next day, same thing. Does Lacquer react to CA (or vice versa)? can CA only be used to fill after lacquer?

Are you seeing a difference in porosity/absorption? The wood will soak up the lacquer whereas the CA glue will not, maybe giving rise to a small hump. The answer is to keep building up the lacquer till you can sand back level with the hump and still leave lacquer over both. Does that make sense?!
