I’ve been using Zinser dewaxed full strenght as a sealer. The directions say to cut it by 25%. Is that really necessary? I’m using it on poplar for a sanding sealer.

I’m not that familiar with Shellac, but I have never cut it when I did use it.

Not necessary if you are using it as a sealer. But if you are using it as a washcoat, I’d dilute it down by a half.

If you mean the sealcoat, I use that a lot and never thin at all.

I would thin it to about a 1-2lb cut for a sealer with DNA…

You could probably add 1/3 more of DNA and it would work great for a sealer…

I don’t think I’d use it straight out of the can unthinned for a sealer… you’d be wasting shellac and I think you’d be sanding more too…

With a thinner cut, it would seal better, dry faster, and wouldn’t require as much sanding.

IMHO

Two applications of 1lb cut of dewaxed shellac, would be more effective. Your want better penetration to help control blotching on poplar.

FWIW, sealcoat is a 2lb cut.
I’ve never had issues with drying time, sealing or sanding.

I always cut Sealcoat 50/50 with DNA.

I also cut Seal coat at least 50% when using as a sealer and sometimes as much as 75% for hard closed grain woods.

I was only 17% OFF!

50/50 sounds good!

I think I remember that Scott Phllipps does 50/50…

It isn’t super critical… but it sounds like you should be thinning it…
