Computer-controlled electrostatic coating eliminates the inconsistency that plagues traditional sanded papers. UArt's process deposits aluminum oxide particles uniformly across every square inch, ensuring predictable tooth whether you're working center sheet or at the edges. This matters when layering soft pastels, you need reliable surface response throughout the composition, not random patches where the grain suddenly changes character.

Seven distinct grades address different technical demands. Rougher 240 and 280 grades hold multiple layers of soft pastel for bold, painterly approaches. Mid-range 320 and 400 balance tooth with control for general work. Fine 500, 600, and 800 grades suit colored pencil details and precise mark-making where excessive texture would interfere. The paper accepts underpainting from water, oil, and alcohol-based media without losing tooth or allowing seepage, structure stays intact through aggressive wet techniques.

pH-neutral, acid-free composition prevents the yellowing and degradation that compromise archival work. Engineered to minimize lignin content, the paper maintains stability over decades. Available as individual sheets or trial packs containing one sheet of each grade, letting you determine which surface suits your specific techniques before committing to quantity.
