Sealing paint on cardboard effectively requires priming the surface first. Apply a layer of acrylic gesso and let it dry. Once primed, paint as desired. To seal, use a clear acrylic sealer or varnish. Spray-on sealers are ideal for even coverage. Apply multiple thin coats, allowing each layer to dry. This will protect the paint from moisture and wear, ensuring durability and a professional finish.
