Things You'll Need
Instructions
Print your photo. Carefully remove it from your printer.
Spread a newspaper or other waste paper on a solid surface. Place your photo, printed side up, on the paper.
Put some waterproofing liquid in a small container (not plastic) that you can throw away. If you don't have anything that fits the bill, line a small plastic food container with aluminum foil and pour the waterproofing fluid into it.
Dip the brush or sponge in the liquid and brush it on the photograph. If your brush or sponge fits inside the waterproofing-material can, simply dunk it inside, dab off the excess and paint the photograph.
Let the photo dry for a few minutes.
Pour the leftover waterproofing liquid back into the can and seal tightly.
