Acrylic paint alone will not make cardboard waterproof. While acrylic paint provides some water resistance, it does not offer complete waterproofing. To make cardboard fully waterproof, a sealant or varnish should be applied over the acrylic paint once it has dried. Apply multiple thin coats of the sealant to ensure thorough coverage and protection against moisture.
