<p>A polymer composition for coating film formation which, when applied even to a considerably rough surface, dried, and then wetted by water, gives a coating film having sufficient elongation and strength. The polymer composition comprises: an emulsion of either a polyvinyl acetate homopolymer or a copolymer of polyvinyl acetate with one or more monomers selected among acrylic esters, acrylamide, acrylic acid, methacrylic acid, methacrylic esters, maleic acid, maleic anhydride, and fumaric acid; and one or more ingredients selected among aqueous solutions of saps, fruit juices, honey, and saccharides.</p> |
