Stain-blocking and mildewcide resistant coating compositions
First Claim
1. A tannin stain-blocking aqueous coating composition for precipitating tannin stains containing a synthetic or natural polymer and a zinc ammonium complex solution, with said zinc ammonium complex solution being present in an amount of between about 1 to 25 percent by weight of the total weight of the coating composition and having a formula Zn(NH3)2+n X.H2 O where n is a number from 4 to 6 and where X is selected from the group consisting of acetate, borate, carbonate, citrate, and phosphate, with said zinc ammonium complex precipitating said tannin stains thereby rendering said tannin stains insoluble.
