Is Electric Paint waterproof? Bare Conductive’s Electric Paint is not waterproof, however it can be sealed with paint, varnish, or waterproofing spray. Have more questions? Submit a request Comments Navniet Kumar 25 July 2016 16:05 Does that mean the Electric Paint will still be conductive even if you put a layer of waterproof paint over it? Bare Conductive 26 July 2016 13:45 Yes, however if you are connecting components to it such as LEDs you should attach them before you seal it as the seal creates an electrically insulating layer, but if you are using it as a capacitive sensor then it will work through the insulating layer.
