USING HYDROLAC POWDER
FOR HAT STIFFENING
INSTRUCTIONS FOR ONE HAT
1. Using a plastic
“throw away bowl and spoon”, while stirring, add 1/2 of the package
(or 1/3 cup) of the HYDROLAC* Powder to 1 cup of
isopropyl alcohol (70%) and 1 TABLESPOON of water.
2. Stir until lumps
are gone. Mixture will be thick like oatmeal or wallpaper paste.
3. Cover with
plastic wrap. Allow thick slurry to stand for one hour in a safe place and
away from children and open flames. Mixture will become clear and liquid.
4. Pour mixture into small spray bottle.
5. Spray the under side of the brim lightly and use
a bristle or foam brush to smooth the HYDROLAC into the felt.
6. Allow the brim to dry. Re-apply if necessary
8. Set with steam.
You can use an iron or pot of steaming water
the hat to SET the HYDROLAC.
Quite often, the crowns are not stiffened at all. I use one coat on
the inside of the crown and two coats on the brim... If you use a little
tension while ironing, you can take advantage of the damp fiber and iron out
any remaining wrinkles or imperfections. Steam setting the HYDROLAC at the
crown and brim juncture is very important.
**ALWAYS TEST SOME EXTRA FELT WITH THE
HYDROLAC AND LET IT SET FOR A WHILE IN A WARM PLACE… ALSO… YOU CAN CHECK TO
SEE IF THERE IS ANY COLOR DISTORTION WITH THE LIGHTER COLORS. IF YOU USE
ALCOHOL ON HIGHLY DYED FIBER …THAT HAS NOT BEEN RINSED WELL DURING THE
DYEING PROCESS.... COLORS MAY BLEED BE ALTERED SLIGHTLY.
*** IF YOU DECIDE THAT YOUR HAT IS TOO
STIFF… SATURATE THE AREA WITH ALCOHOL AND SOAK UP WITH PAPER TOWELING.
RESHAPE AND LET DRY. REMEMBER TO RESET THE HAT WITH STEAM.
Hat Shapers does not recommend making HYDROLAC
Hat Stiffener in quantities larger than you will use in one session. It
becomes flammable with the alcohol and may not be safe to leave unguarded.
It will however, remain useable for a day or two.
