S Group: Forum Members Posts: 6, Visits: 15	I'm using Glasscast 50 to fill a mold over a photo. Despite spraying several coats of Acrylic lacquer, and coating the edges carefully, I'm still getting the resin creeping or leaching into the edges of the photo, discolouring it's appearance. Whatever I use must be fully transparent and not react with the resin cure process. Help! What can I use to prevent this happening???

Once cured, it cures translucent and will form a thin skin over the photo so that the resin cannot get under so easily. A lot of lacquers, especially if rattle can, may soften with the heat generated with the resin cure and that is enough sometimes to lift the edges and expose the paper to resin soak in. If you really struggle, you can PVA both sides. Thanks Warren. I'll try this and let you know the results.

Warren, despite using Gorilla Wood Glue and carefully coating the edges several times, the resin is still seeping in. Any more ideas please??
