Cayrex has many fine instructional videos which I recommend.
However, I do not use the above method. Acetone is flammable and a lot of dust is generated.
I use "acrylic caulking (containing silicone) / caulking gun:
With caulk and activated carbon/ graphite , I create a thick paste which I smear on parchment paper and 6-ton press for one hour:
I will attempt to heat press a current collector on a section of the above hardened paste in a day or so.
The middle electrode (above) has a fine steel screen pressed in with a "tortilla" hot plate ( two 10 second heat presses. Be sute the electrode is sandwiched between parchment paper sections to avoid sticking. It works!
Use an iron if that is available.
I like the caulking approach to avoid the solvent and dust.
