To seal cardboard for painting, start by applying a layer of gesso or acrylic primer to create a smooth, sealed surface. Next, allow the primer to dry completely. You might need multiple coats, so repeat the process if necessary. Once dry, lightly sand the surface to remove any rough spots. This will ensure your paint adheres well and the texture of the cardboard doesn't show through.
