Stain, Sealer, Shellac!
If I want to seal in an Alcohol Dye stain, so I can use Shellac as my final finish, is there anything other than
Sanding Sealer I can use to seal the stain so it doesn't lift the stain?.
I've seen these two products which are water based and are promoted as 'Timber Sealers'. Has anyone tried these to seal in a stain?.

Add a little shellac to the stain and it will hold on hard enough to use shellac over the top . 5% should be enough to work and will hardly change the stain at all .
As soon as you get a coat of shellac over the top of such a stain it also holds well from that point. So a polisher will sometimes just give a very thin fast coat of shellac with a brush that doesn’t disturb the coat of stain. It has to be a fast almost dry coat though . Not sitting there wet for any length of time . Fast thin dry and follow up instantly with a go over with the heat gun and as long you not pulling up colour with the brush all will be good . You won’t pull up colour if it’s fast dry and thin.

If you’re a chicken like me you can spray the stain and shellac on. I used an airbrush to spray spirit stain, followed by shellac onto a gramophone I restored. Obviously a bigger job calls for a bigger spray gun.

I have no issue wiping the stain on, its keeping it on and not re-dissolving the stain that's the problem. I have tried spray, roller, wiping, brushing all to varying degree's of finesse and none have worked. Just to give a little context the area to be stained & finished is 4x2ft coffee table top. The colour will be going from white oak veneer to a dark walnut.
Examples below are on Veneered white oak: left to right: first two boards are stained then sanding sealer applied (unfinished), boards 3-6 have coats of polyurethane on using different applications and tones. None of the finishes have been finished (polished or taken to a satin sheen):

The picture above is only an example of how dark the finish is I'm looking for.

I will be trying Robs suggestion tomorrow and if that doesn't work for me I'll give the Intergrain ultraprep primer & sealer or the Bondall Monocel All Purpose Timber Sealer a go.
