The invention relates to plastic sizing agent for a silane-modified single component wet cured polyurethane playing court; the plastic sizing agent comprises 7 to 11% of isocyanate, 25 to 40% of polyether polyol A, 1 to 3% of polyether polyol B, 10 to 20% of dissolvant, 20 to 40% of solid filler, 5 to 25% of plasticizer, 0.1 to 5% of silane coupling agent, 0.4 to 2% of pigment, 0.1 to 2% of anti-aging agent, 0.1 to 2% of ultraviolet absorbent, 0.1 to 1% of water, 0.001 to 0.1% of catalyst and 0.001 to 0.1% of polymerization inhibitor. The plastic sizing agent for a silane-modified single component wet cured polyurethane playing court is suitable for basketball courts and indoor venues, is convenient to use, does not need to be blended, and has stronger cohesive force with bottom foundations and low requirements on environment moisture; and after the plastic sizing agent is modified by the silane coupling agent, all indexes of the plastic sizing agent are superior to national standard.
