To waterproof a cardboard box, start by covering it with a layer of acrylic varnish, which will act as a sealant. Next, apply a coat of water-based polyurethane to further enhance the waterproofing. Make sure to cover all surfaces, including edges and corners, for full protection. Let each layer dry thoroughly before adding the next. This method provides a practical, cost-effective way to protect your cardboard box from moisture.
