Luckily, several waterproofing techniques can turn paper creations, including origami masterpieces, into durable artwork for outdoor display or for use in handmade jewelry. However, waterproofing techniques don’t offer a one-size-fits-all solution, as each technique has its own advantages and disadvantages. Select the procedure that best suits your piece for a timeless presentation.
Clear Nail Polish
Coating origami with clear nail polish is, by far, the most economical waterproofing method for small pieces. You can often find clear nail polish for $1 to $2 in drugstores or discount stores. This technique is used to seal and protect rolled paper beads before stringing them onto necklaces, bracelets, and earrings. For added sparkle, use clear nail polish with glitter mixed into the formula.
Mod Podge
The Mod Podge crafting medium is typically used for adhering several small bits of paper to a larger surface, such as in decoupage projects. However, it also works nicely as a protective coating for origami models. Mod Podge comes in both gloss or matte finishes. while specialty Mod Podge—used to add pizzazz to your piece—includes glow-in-the-dark, antique, and glitter options. Use Mod Podge finishes for home decor pieces that need protection from dust and dirt. It works well on origami jewelry projects, also.
Wax
A coat of melted beeswax or soy wax offers an organic way to waterproof origami, and it’s particularly ideal for making origami boats. Just fold your boat as desired, then use an old paintbrush to apply a coat of melted wax to all the exposed areas. Be careful to avoid dripping the wax on your skin, as it may burn, or on your work surface, as it’s hard to remove.
Acrylic Sealer Spray
Acrylic sealer spray provides a convenient way to create waterproof origami. Spray the paper before folding it or apply it to the finished product. Use acrylic sealer spray on origami wreaths to hang on your door or on outdoor wedding decorations. For best results, hold the can 10 to 12 inches from the paper’s surface and apply the sealer with a slow side-to-side motion, using two or three coats, and letting the sealer dry completely between applications. Make sure to work in a well-ventilated area or use a respirator to protect yourself from harsh chemical fumes.
Polycrylic
If you want a tough-as-nails clear finish, apply several layers of polycrylic to your folded design. Polycrylic is a water-based brush-on polyurethane that’s usually used to give wood surfaces a protective topcoat. Simply paint it onto a small or large origami creation for a durable finish. Use it to make decorative refrigerator magnets or tabletop animal displays.
Waterproof Paper
Plan for waterproofing origami ahead of time by selecting water-resistant materials. Several brands craft waterproof and tear-proof paper that is ideal for origami use. A synthetic material called Tyvek provides the ideal medium for outdoor origami, as it’s made of flash-spun polyethylene fibers. You can also use wax paper cut to the appropriate size (found at any grocery store). Fold the wax paper into origami party cups that guests will actually be drinking from.
Plasti Dip
Plasti Dip is typically used to create on-the-fly sturdy rubber tool handles. Dip your origami into a container of this solution, like a carpenter would dip a wooden hammer handle, and you’ll end up with a rubber sculpture that can be displayed however and wherever you wish. Do note, though, that Plasti Dip creates a thick coating on the paper, making this a poor choice for projects with fine details. However, for abstract outdoor sculptures like a hanging origami crane, Plasti Dip serves its purpose.
