Rock Hard Stiffener?

[Randalscott]

Hi Folks,

I'm new here, so my apologies for any mistakes. I am looking for any insight or suggestions for how to stiffen a wool felt hat to a virtual rock hardness. Seriously.

I've tried a few things, including the shellac method which didn't last long, and as soon as I got rained on, it was like it was never stiffened it at all.

Has anyone used anything that seriously stiffens a hat? I'm considering a wood hardener, even. Anything, as long as it's safe and does the job.

Thanks.

It is weird the shellac did not work. Perhaps your solution was not strong enough. Shellac should, in a strong solution, and will make the hat as hard as you want. Multiple applications might be needed but shellac is not affected by water....hence its use by woodworkers. Did you use a spray shellac? Never use that. Buy flakes and dilute in denatured alcohol. Mix thoroughly (it can take up to 24 hours to fully dissolve).

Its possible it wasn't strong enough...I dont know. I sure thought I used a lot. I didnt use flakes though; I used a store bought shellac. I certainly read, researched and listened to those with more knowledge & experience than I have (which is everyone). Also I brushed it on.

I use a very dilute amount as I never am looking to stiffen a felt very much. I use a tablespoon in a cup of denatured alcohol. A fellow hatter I know that makes very stiff crowns uses almost a 50/50 mixture of shellac to alcohol (by volume).
