[0002] Plastic track is a surface material used for sports venues, mainly used in places such as track and field stadiums, playgrounds and gymnasiums. It is usually made of polyurethane, polyvinyl chloride or other plastic materials, has a certain degree of softness and elasticity, and is suitable for competitions and training of various sports. The steps to repair a damaged plastic track include: 1. Overall cleaning, remove all damaged plastic layers where there are cracks in the surface layer of the track (the removal shape is basically circular); 2. Repair the bottom layer and remove the plastic layer, first apply the primer, then mix the glue and granular mixture in proportion and fill and level the bottom layer. The newly laid plastic granular layer should be flattened, and the side seams should be consistent with the thickness of the bottom layer; 3. Prepare the spray material and use a special sprayer to spray the entire surface twice.
