Is near a craft gum or sealant I can put over paint on fabric? My son and I have made his Nona, my mom, a bequest...

My son and I have made his Nona, my mom, a bequest for Christmas by painting his hand and placing them around a picture on an apron. But I want to secure the paint onto the apron so that she can swab it. Is there a crafting spray I can use to trademark the paint and make it washable?
Answers:    Actually, in attendance isn't. If you used latex paint, it is lying on top of the yard goods and will eventually crack and peel stale. If you need to repeat it because you've used latex, try having your son put on a sticky pair of knit gloves, dip them within dye, and then do the handprints. Wash the apron contained by vinegar solution to set the dye. If it is too cute to redo, update Nona the apron has to be spot cleaned. If it is an heirloom, which it sounds resembling it is, then she won't "wear it out", I'm sure. Also, if you're not going to rehash it, I would get a accurate scotchguard product and spray the apron. That would help.
There are Always sealants, close to for the bathroom tub..They are usually Silicone based..It other depends on the project.
