We’re very excited to have finally cracked the code on waterproofing air-dry clay! At long last and with many iterations we have developed a brilliant waterproof varnish! Easy to apply, non streaky, non sticky and with amazing coverage. How to use our varnish: 1. Wait for your piece to dry completely for a minimum of 2 - 3 days. It’s important your creation is bone dry before painting (very light in colour and hard to the touch). 2. Apply 2 generous coats of our white acrylic eggshell base layer on the inside, outside and base of your creation. Allow this to dry for a couple of hours. 3. Apply 2 generous coats of our ultra glossy or matte varnish on the inside, outside and base of your creation. Allow this to set completely overnight to ensure a waterproof finish. And that’s all there is to it!
