This is the workhorse behind every flawless decoupage finish: Redesign with Prima's own gel medium, formulated to glue down decoupage papers and fibers and seal them in one product. The matte version dries to a soft, no-glare finish that lets the paper's artwork do all the talking.

Brush a layer onto your surface, smooth the paper into it, then top-coat to seal. The 230 ml jar has a creamy consistency that won't soak thin fiber papers into transparency, and it cleans up with water while wet. If you're building a decoupage habit, this jar disappears fast.
