A method of coating a silicone rubber substrate, the method comprising (i) applying a coating composition comprising (a) about 50-80 wt % of a water-based silicone elastomer composition; (b) about 0.5-4.0 wt % of a silane adhesion promoter; (c) about 0.02-0.5 wt % of a silicone surfactant; and (d) about 10-50 wt % water to the silicone rubber substrate to form a coated substrate; and (ii) applying an acrylic material to the coated substrate.
