I’m pleased that my technique for applying textured silicone to vellum is working for the people who have tried it.
In the interest of making this even easier, I’ve improved on the technique to apply the silicone.
I now thin it with Zylol at a 1:1 ratio, mix well, and pour it onto the vellum. Here’s the cool part that makes it easy-peasy.
I roll it out over the surface with a foam rubber paint roller like the ones they have at hardware stores.
The texture produced is micro-bumps on the surface. I applied two coats, and now the silicone layer is about half the thickness of the squeegie/fabric technique!
It produces blobs with a light touch, but it still needs a few more coats to be as sensative as the squeegie style sheet. With this technique of application, it’s even easier to get a good, even coat of silicone onto the vellum so building it up in several layers is not so hard to do. It just takes a little wait time between coats. I waited an hour on the first one. It felt like it was cured up pretty well after 30 minutes, but I gave it another 30 minutes to be sure it wouldn’t lift.
I think I’ll make more and do about 5 or 6 coats.
Here’s a how-to video I made:
You can clean the roller pretty easily with the zylol and a rag. Just get the roller wetted out with the zylol, then roll out the excess onto the rag. Dispose of the rag in a fireproof container or hang it to dry. NEVER put solvent soaked rags in the trash. They can self ignite.
Have fun rollin the silicone!
