Thread: keeping sandpaper from curling?

Wet Dry sandpaper curls up when it gets wet. Makes lapping stones a little harder. Anyone have a way of preventing this?

use double sided tape to keep it flat on a surface?

Is the wet or dry paper good quality? I lap my hones on a piece of plate glass, the water makes the paper stick flat to the glass.

I'd use a fine mist of 3M Spray Mount on the back of the sandpaper and tack it to the plate glass before getting the surface wet.
I think double sided sticky tape would give raised areas, spray mount lays flat.
Also, in a previous post, I read hair spray works.

I'd just let them curl up. It seemed to round the edges of my hone while I was lapping it.

I also got high spots from the two side tape. Also the paper still bulges a little when taped. Was thinking of wood glue but might try the 3m spray. It's called spray mount?

This messed up my lapping job on naniwa 12k. I had to go back and re-lap
