Abstract A sprayable photocurable surface coating composition consisting essentially of; (a) 1 part of a polyene having at least two unsaturated carbon-to-carbon bonds per molecule; (b) about 0.2-1 part of a nonionic emulsifier; (c) about 1-50 parts of water; (d) about 0.1-2 parts of carnauba wax, paraffin wax, or a mixture thereof (e) about 0.05-0.25 parts of a photocuring rate accelerator; (f) about 0.1-2 part of glycerol; (g) about 0.1-2 parts of paraffin oil; and (h) a polythiol component containing at least two thiol groups per molecule, the polythiol component being present in an amount to provide about 0.06-1.1 equivalent of polythiol per equivalent of the polyfunctional component, the total functionality of polyene plus polythiol being greater than four.
