Surface parquet wood surface construction cement grassroots should be smooth, hard, dry and free of grease and other impurities, moisture content should not exceed 9%. When the grass roots from the sand surface pockmarked face, cracks phenomenon, should be brushing (Scraping) emulsion putty processing, each time brushing putty thickness should not exceed 0.8 mm, dried and polished with a 0-iron emery cloth, apply Brush putty second time until after the smooth surface, and then diluted with water emulsion brushing again.
