Shellac as a sanding sealer - then what?
I have sanded back the scratched top of a pine dresser to bare timber, and now want to apply oil based Cabots ‘Jarrah Stain and Varnish’ to match the rest of the dresser.
I am aware that when applied to pine, this stuff can result in a blotchy finish, will be absorbed in some areas, and sit on the top of others.
Have painted the bare timber with a #1 cut shellac. What happens next?
Do I lightly sand the shellac off, leaving the grain holes filled with shellac, or do I apply the varnish straight on top of the shellac?
LATE NEWS: After the one coat of shellac dried, I found the surface was rough with raised grain, so it needs to be denibbed with 1200 grit paper.
Do I sand it any further?
The question still remains, can the oil based varnish be applied to shellac?regards,

Thanks jack620, after applying the first coat on top of the lightly sanded shellac, I am inclined to agree. Hopefully the next 2 coats will see a big improvement.
And that stuff is not cheap, $23 for 250ml, $60 for 1 litre. Fortunately I found an unopenedtin I bought 5 years agaoregards,

Yes, you can apply an oil-based varnish on top of a shellac sealing coat, provided you have used a de-waxed shellac.
If home-made then the shellac mixture must be made from blonde (dewaxed) shellac flakes.
