1. A slurry, adapted to modify the rheology of a latex paint composition, comprising:

  • (a) from about 40% to about 45%, based on the total weight of the slurry, of a particulate water-swelling polymer having a molecular weight of about 100,000 to about 20 million;

    (b) from about 20% to about 30%, based on the total weight of the slurry, of a water-insoluble organic carrier vehicle which is a non-solvent for the water-swelling polymer;

    (c) from about 20% to about 30% of a mineral oil based defoamer, wherein the defoamer is adapted to actively reduce foam in the latex paint composition;

    (d) from about 2% to about 4%, based on the total weight of the slurry, of a non-ionic surfactant having an HLB value of about 8-12; and

    (e) from about 0.15% to 0.25% based on the total weight of the slurry of a particulate thickening agent.
