When you are done with printing then you need to wait about five minutes for it to be completely dry. To do that you will need a well-ventilated area where you should spray the entire surface of the waterslide paper.
They repeat the process two more times so that in the end, it has a total of three coats. You should wait for about ten minutes in between each coat.
Seal your image with a clear spray paint that has an acrylic base. We could try Rust-Oleum 2X clear, as well as Rust-Oleum Crystal Clear enamel, which is a good option.
It is best to place your decal at room temperature in lukewarm water.
When you print onto waterslide the ink is laying on top of the paper if you do not seal it, the ink will run off your paper when you place your decal into the water to activate the adhesive.
