Nursery grounds epdm: 120 yuan / square meter EPDM has excellent resistance to environmental aging, heat aging resistance, ozone resistance, chemical resistance, water resistance and low temperature resistance, and has good electrical insulation and flexibility, as well as excellent color stability, enduring color products. 1, highly scalable, solve problems because of the foundation structure and thermal expansion or contraction produced two, three high permeable breathable, able to EPDM materials required for the design patterns and various signs 4, flexible, reduce sports injuries 5, 6 long-lasting and durable, suitable for indoor and outdoor venues seven bright colors, a variety of options situ elastic floor construction process description the main raw material for cast resilient flooring adhesives and rubber granules, its product characteristics, and the underside of the base Construction process requirements more stringent. Use our products should note the following: First, the basic requirements of a bottom surface of the foundation is prohibited due to cracks and uneven heaving caused by freezing. 2. There must be a better basis for flatness and slope requirements. 3, the surface must be flat to ensure drainage. 4, the base surface should be kept clean and dry, after the completion of the foundation, the stringent requirements of the maintenance period over 21 days. Second, the construction process requires a construction classification, there are two construction technology, mechanical and manual pavement paving. Because now is the bridge construction site, the slope is relatively large. Not suitable for mechanical paver. Paving by hand only. 2, surface preparation to meet the requirements on the basis of, first clean the surface with butyl, can not exist any stolen goods, dirt, water (including the watermark), oil and so on. After cleaning, apply evenly on the basis primer (diluent: glue by 3-4: 1 ratio, stir), to enhance its bonding capacity with the ground, to avoid irreparable consequences. 3, must be aware of the following pre-construction sample test questions a: the use of materials, such as feed ratio, material curing time is normal. b: 24 hours after the observation whether the phenomenon is not solid and adhesion, strength and other properties whether the requirements. Mixing machine, etc.), materials and catalyst preparation. 4, the preparatory work before work (manual) materials, tools and equipment (closed, Gunzi, soapy water, car, rake, stir
