PU construction method: Infrastructure Requirements: 1. place after the first water pond mud floor drain clear. 2. backfill sand, stone grading, layered rolling dense. 3. Application Level stadium floor height, leveling bubble measurement accuracy does construction, after the completion of no water phenomenon. Construction methods: 1. Ground renovation: PU elastic material to be laying the ground before construction clean up, dust completely removed, and the ground projection shall emery cloth or spatula eradicate polished. 2. Maintenance phase: laying new venues should be 3 to 4 weeks maintenance period, another cement of stable and dried before the laying of PU elastic material. 3. Determination of ground water with transparent tape to tape patching around the ground, to be 2 to 4 hours if condensation is not internal construction, or take a newspaper shop on the ground and then to the plate covering the construction, the newspaper the next day remove the ignition If not ignite, said ground water is still not much construction. 4. Substrate: (Primer) construction, when the ground is really constructability extent to brush clean up after the uniform rate of aqueous coating on the substrate coated with the construction site, only one hour after the coated substrate. 5. Material mixing: A: agitation must first place with tape bedding to make sure the floor clean. B: when the material is enabled, the cover must first clean. C: should pour hardener (transparent liquid) and then pour the main agent (color liquid) into the mixing barrel straight down the barrel should be central, not along the barrel along side down, in order to avoid the barrel side not completely mixed. D: When mixing, the mixer should move around, and the material was thoroughly stirred. 6. The coated substrate: the first about 2mm thick coated substrate will stir the material down to the floor, with toothed trowel applied to control the capacity to ensure thickness. 7. Level Finishing: After 24 hours apart after the coated substrate, forming material has hardened, then sprinkling on the surface, and then specify the location of the water drain clean water, and then the same material to pave the low areas. 8. bed material coating: after the completion of a comprehensive second level repair coating special attention to control the thickness of 2mm thick, and strive to fully flat. 9. slip treatment: complete bed coating material, and then to finish (UA-200) slip agent mixed in proportion to the spray gun on the surface layer in order to adhere to crystallize on the surface layer of slip effect. 10. crossed: A court in accordance with the standard size measurement after the line marked with ink. B PU crossed the materials must use white paint or automotive paint (white) coating, if other sites use the designated point mark with other colors to altruistic use.
