I've painted & decoupaged the outside of a plastic water bottle. What should I use to make it waterproof? Thank you!

You can try putting a marine spar varnish on it. Because it is a plastic water bottle none of your work may hold up for long.It will have to be very gently handwashed and dried.
Three coats of a spray water based polyurethane. Once dry it is waterproof. Clear spray paint would work.
Thank you. It is a vase for a small bunch of flowers. Cut bottle mid way, took the top part, with the cap, which will hold water, turned it upside down in the bottom section. Thank you for your suggestions. Ilene
Hi Ilene, you can also use outdoor mod podge to waterproof your decoupaged plastic bottles.
Thank you! Didn’t know mod Podge made an outdoor product. Ilene
I bought Mod podge that can go through the dishwasher! Who knew? Ilene
