You will have to repeat this process for the 320-360 and 600-grit sandpaper.
The coarse side of the sandpaper should be facing away from the sanding block. You can pick up a foam or rubber sanding block at your local hardware store or order one online.
Wet-sanding is what allows you to polish the acrylic and make it look shiny and new. If you forget to use water, you could damage the acrylic and make it unusable.
To get a feel for sanding acrylic, practice on extra scraps that are left over from your project.
Take breaks in between sanding so your hand doesn’t cramp.
The higher the grit of the sandpaper, the finer it is.
Other uses for the torch include melting snow and ice on outdoor staircases and walkways, starting fires, and removing old sealant on windows.
If you don’t have any excess acrylic, go out and buy some for this specific purpose.
It usually takes a couple of minutes for the acrylic to cool off after it’s been torched, so wait at least that long before touching it.
Remember to allow the edges to cool before making a second and third pass over the acrylic. If you re-torch the acrylic too quickly, the material could melt or burn.
