A thin tough glossy surface may be applied to a flexible substrate in a one step process comprising: applying an aqueous thin film of a compound of a polymer to an endless carrier belt made of a material having a low adhesion to said polymer, contacting the flexible substrate and coated carrier belt and keeping them together while they pass around a hot drum laminator at a temperature of from about 100 to about 150.degree.C. The process is suitable for applying impermeable surfaces to non wovens, and foam backed carpet. |
