I’m making some signs using clear cast acrylic that have a black spray painted backing, but unfortunately, I will not be able to do a reverse engrave on the backs of these because they are way too large to fit into my GF Plus.
I’ve done a little reading online, and it sounds like the regular etching cream that’s used for glass and porcelain most likely will not mark on acrylic at all, but it does sound like acetone might do the trick.
I have a Cricut and thought about making vinyl stencils for the acrylic and then apply the acetone over the vinyl stencils.
Anyone have experience doing anything like this? Do you think the acetone burn through the vinyl stencil and cause a melted mess or seap underneath the stencils? I wondered if I could possibly mix the acetone with something else in order to make a paste or gel out of it so it can be brushed on so it’s not like water that will run everywhere. I have no idea what I could use as a thickening agent that won’t cause some dangerous reaction or lessen the effectiveness of the acetone.
I’m concerned about being able to get all of the air bubbles out of the vinyl. It’s for a wedding and I’d hate to have tiny air pockets all over the vinyl lettering. If I could apply it without that worry I wouldn’t mind doing it that way.
Professional vinyl graphic installers use application fluid, it lets the decals ‘float’ for a little while so you can place them perfectly - spray on surface, apply the vinyls, squeegee out the fluid and any bubbles with it. The squeegee with the felt wrapped edge is usually better than a plain plastic one for this purpose.
Appliaction fluid is easy to find but you can also use water with a little dish soap mixed in.
Long before I had a GF I was doing sand carving with a variety of sandblasters. At one time there was a wonderful online community of carvers very much like this forum. Amazing work can be done with this art form. I bought most everything needed from Harbor Freight, including an air eraser, which is essentially and airbrush for sand. It allows for freehand and detail work.
