Where is a good place to get flake form 100% de-waxed shellac suitable as a sealer for underneath KTM- SV?
thanks

Wood Essence has flakes if you are interested in making your own mixture.They have good product and good to deal with.

LMII has it too.

Or you can use Zinssers Seal Coat or Spray Shellac. Those two are de-waxed.

I have a pound of dewaxed superblonde on the way. I tried the Zinsser stuff and had adhesion issues. I was able to peel off the bridge area like a decal, which was very convenient but nit very reassuring. This was with both the aerosol, and the premixed stuff through a Preval. I'm hoping fresh mixed stuff saves the day.
As an add-on question, can isopropyl rubbing alcohol be used as a mixer?
Thanks

I've heard of people using it, but not very effectively. Too much water. If you were having adhesion problems with Zinsser, there was something else going on. That's what I use when I'm working my tops, and it sticks like crazy, and I tape to it, with no issues, or peel up problems.

The issue was not making the shellac stick to the wood, which it did, but making the SV stick to the shellac.

Just wondering, did you use "Zinsser Shellac" or "Zinsser Seal coat"? I've had issues with zinsser shellac (which should NOT be used as a sealer - indeed adhesion issues) but all seems fine with the Seal coat.

The regular Zinsser shellac is not de-waxed. Only the Seal Coat and the Spray.

Same problem with spray and Sealcoat.

Well, now I know that KTM-SV doesn't stick well to the Zinsser stuff! For myself, I'm using polyurethane. Like I said, I only had issues with Zinsser Shellac, but the Seal Coat worked well for me.

Frankly I would not base your decisions on my very limited experience with spraying. I am following a recipe that others have used successfully for a long time, so now I am just trying to reduce variables. I cannot attest for the shelf life of the shellac I used, either the premixed sealcoat or the spray can. So don't throw out the baby and the bathwater based on my singular result. I am really hoping to find how to make SV work for me as I think it's great stuff. It's just now a matter of finding out what is causing my particular set of kerfuflicities.

it may be in your prep. if you sand much beyond 220 grit you can get the wood too smooth for things to stick .

The problem is not getting shellac to stick to wood, but to get the SV to stick to the shellac... Wood was prepped to 220, shellac scuffed with a...a...a...scuffy pad.

Great to deal with, and great fun to brouse thru all the wierd stuff he has.
