In order to ensure the effect of laying a large area (flatness, strength), it is recommended to be used before laying on the leveling layer of the use of oil and self leveling, especially the transformation of old buildings. For details, please refer to the manufacturer and recommend the products and practices according to the ground conditions. In order to ensure the laying site has sufficient strength to support on the structure of each layer, and under high load in the future, that should choose high grade leveling layer, such as fine stone concrete practice, it is recommended that the mark of C30. Cement mortar should be in strict accordance with the national standards or M15 standards. The strength of cement floor as an example, the other floor separately. Rubber flooring materials and auxiliary materials, should be placed in a safe and reliable indoor, and keep the ventilation dry and light, not stacking. Coil should be kept upright, rubber parts should be placed free of pressure, the indoor temperature of 15 degrees C.
Surface density: the surface should not be too rough, not excessive pores. The surface should be treated by surface hardening for lightly sand. Cracks: shall not have a width greater than 3mm cracks. The surface layer without hollowing. Surface cleanliness: oil, wax, paint, pigment and other residues must be removed. Temperature: the temperature to 15 degrees the laying site should be C. In addition: should maintain the level of reference. The building settlement joints should have proper sealing. Recommendation: according to the level of the thickness of the layer and the laying time of the rubber floor plan, the level of construction and laying of rubber floors should be not less than 28 days to ensure that the strength and floor drying
Rubber flooring before laying foundation for humidity: according to the manufacturer's glue, soil moisture content (weight percentage) should be less than 3%, when the weather or external water, should make the air circulation, and timely erase surface water. Air humidity in the construction site should be maintained at 20%-75%. Surface hardness: use a sharp chisel to quickly cross the surface, the intersection should not burst. Surface roughness: with 2 meter ruler, the gap should not be greater than 2mm
