POLISHING BLACK ACRYLIC

[Steve Underhill]

Flame polishing ideally, failing that very fine sanding, (with the foam pads not sandpaper) then fine wire wool, and finally brasso or T cut.
you’ll get a shine.

I got some diamond embedded cloth pads of various grit sizes from a stone carving shop, expensive but last for ages, give a good result… go up to about 2000 grit size as well. Use like wet & dry.

Hey how about this one – sand the edges and just wipe them over with some dichloromethane (the thin watery glue you use for stickin acrylic together)…and bingo polished edges

[Mike Grant]

Flame polishing discolours some colours of acrylic so do a test piece first.

is this the stuff similar to acryfix paul?

[David Rogers]

Acryfix is/was a methyl methacrylate glue. (Tensol also has the save active component)….whooooah, glue sniffers paradise.

Not used DCM for glueing acrylic before – but used to use Trichloromethane (chloroform) a fair bit…slightly more toxic 😳
Simply wonderful stuff for flawless joints (capillary action). Never thought about it’s polishing properties…hmmm.
