Help me Dribble

I have finally finished my Jarrah hardwood table and the lacquer will not stick to it!
First coat goes down fine and then second coat just makes to first craize...
I only want to sand this thing one more time... Any tips...?

I have had this happen on two occasions. Once was lacquer over a shellac based stain and once was clear lacquer over lacquer sanding sealer. I am not a painter, but I will venture to guess based on my failures not on successes. Plain and simple you are building product too fast. No-one brags about two coats of lacquer. I think the bragging rites do no begin before the number twelve. The lacquer is flashing too quickly and shrinking the coat below. My guess is the undercoat gets a chance to absorb far too much solvents and then is forced to let them go too quickly.
Ask the supply house for different solvent flash points use the slowest possible. That could mean actually introducing paint thinner into the equation. If the "lacquer" is not a true lacquer, you can try half thinner half paint thinner.
Short answer
Too much product too short of time.
The piece is beautiful. Simple elegance will out shadow artificial artsiness every time.

Such beautiful wood ... Why laquer?

Seriously - why not an oil finish, rubbed in by hand?

Using Feast and Watson...
Was just going to polish Tung oil in, but as it is a dark timber anyway, I wanted to minimise the darkening.
I may try a sanding sealer under it... Have used Miratone on Redgum before with no hassles.
I was wondering at the cold but have had heaters on... I'm working on the bike now so will paint a patch each day to see if it is curing time. (the glue took almost 3 times as long to set when I laminated it together... Old hard wood?)

The best thing would have been a acrylic spray stain then 1 coat of clear acrylic give a light sand then 1 more coat clear job done.
Thanks for your help Dribble!

It turns out I needed to leave twice the time between coats as recommended... It was the same with the glue
LOL one year latter
looks good mate!
It takes me a while to do things...
You sound like me just ask ktmguy
nicely done Linga!
That's a very handsome table you have there.
Came out looking great. Dinner doesn't look so bad either.
Thanx for the follow up. It does good to know what the solutions to painting problems are. How long betwwen subsequent coats and did you lightly sand between coats?
There is a certain feeling of pride or a feeling of accomplishment when I and others sit at a table I have built. My dad made a table that we all ate at as a children. I and five sisters and one brother plus mom and dad sat around a very similar shaped table. It was no where near the fine grade that yours is but still me and my brother did most of the work. Creating is much more joyous than say sitting around a table. Don't linga around resting on your Laurels or Jarrah for that matter
I had to wait almost 48 hours between coats!
Sanded in between all and hand sanded with the grain down to 1200 grit before paint.
I made it a little taller as I think furniture has shrunk lately.... Now I need chairs!!
I always like making things, even if they are not as good as the real thing

i tend to use as little sandpaper as possible, hate dealing with the dust. 1200 on bare wood is overkill and a waste of your time.
you want some tooth/roughness for finish adhesion. just use a grit so you dont see any scratches in the wood surface, and spend your finessing on applying and rubbing out the finish.
