1. A method for developing a generally smooth, tough, elastomeric surface coating over one surface of a batt of fibrous insulation, comprising:

  • a. applying a foamed or frothed cross-linkable elastomeric aqueous emulsion coating composition to said one surface of a batt at a substantially uniform concentration coating over said one surface;

    b. engaging a hot, smooth ironing surface with said coating to dry and compress said cross-linkable emulsion coating and to develop a cured, smooth surface film over the exposed area of said coating;

    c. separating said ironing surface from engagement with said coating and thereafter heating said batt and coating until said coating is substantially dried and fully cured;

    d. recovering said batt of fibrous insulation having a cured elastomeric cross-linked coating over one surface of said batt, said coating having a generally smoother and tougher exposed surface compared to a corresponding coating of the same cross-linkable elastomeric coating composition on the same batt at the same concentration which has not been exposed to said hot, smooth, ironing surface prior to heating said batt and coating to achieve a final cure of said coating.
