What this decoupage glue and sealer does to paper

Here is Diamond Top Coat, the way we bottle it.

We want the paper to show, not the medium, so it clears as it cures. It goes off quickly, so a second coat is usually a short wait away.

Glue, sealer and finish are the same bottle here — that is the whole point of what we do. Our surface chart lists it for diamond dot art. We keep one of these open on the bench most of the time.

Paper wrinkles because it is carrying too much water, not because it is bad paper. This part of the line is a decoupage glue and sealant mixed thin for exactly that: less water into the sheet, a smooth film that dries clear, and enough grip to hold a finished puzzle together as one durable piece. Thin coats from the middle out do the rest.

★★★★★
Works really well for sealing diamond art. It dries clear. Best product for diamond painting.

Easy to use. Was a little worried when I started painting it on that it would look awful after drying. But it dried clear and looks great. I’ve included a pic of before the top coat, during the top coat application, and after 30 mins of drying.
