The invention relates to a full polish ceramic product and a preparation method thereof. The full polish ceramic product comprises a ceramic green body and a full polish layer outside the ceramic green body, wherein the full polish layer mainly comprises powder which comprises following components by weight percent: 42-62% of albite, 2-7% of potash feldspar, 0-4% of dolomite, 4-8% of calcite, 0-2% of barium carbonate, 6-8% of aluminum oxide, 3-5% of fired talc, 2-4.6% of zinc oxide, 3-9% of quartz powder, 0.5-2.5% of soochow kaolin, 1-6% of calcined kaolin, 5-10% of aedelforsite, 0.1-3.0% of spodumene, and 0.1-2.8% of borocalcite. The full polish slurry is prepared by burdening and ball milling once. As the full polish slurry contains less wearproof materials like aluminum oxide, the ball milling time is short, and the production efficiency is higher; due to the addition of little amount of spodumene and borocalcite, the abrasion performance and hardness of the fired full polish ceramic product can be improved.
