Permastone

Cast durable sculptures that repair cleanly if damaged

Permastone delivers the durability that plaster castings can't match. This specialized compound produces rock-hard results that withstand handling and display without the constant worry of chips and cracks that plague traditional casting materials. When accidents do happen, clean breaks glue back together seamlessly rather than crumbling into irreparable fragments.

The formula sets firm within 30 minutes, letting you move efficiently through production without overnight curing delays. Mix, pour, demold, and move on to finishing, the rapid set time supports both classroom schedules and production workflows where timing matters. Once cured, the surface accepts every major paint type: acrylics for bold color, oils for depth, watercolors for subtle effects, or tempera for classroom projects.

Sculptors working on maquettes appreciate the material's strength during transportation and client presentations. Teachers value castings that survive student handling semester after semester. Relief sculptors and mold makers rely on Permastone when permanence outweighs the working properties of plaster, producing pieces meant for long-term display rather than temporary studies.
