Before the laying of reinforced concrete, it must Xianpu waterproof layer. ? Around the field must have a complete drainage system must be open channel design. ? Site drainage design when using single-sided, discharge slope required to achieve 6 ‰. ? Flatness reach 3 meters road use pressure gauge to measure the error of not more than 3mm. 1.2 basic conservation requirements? New cement foundation must be done 28 days before the hardening conservation construction (winter time extended 1-2 times). ? If the underlying surface from sand or from the powder phenomenon, sandblasting or other mechanical treatment to remove loose material floating layer and make the surface hard, rough and uniform. Then, repeatedly washed with water and at the same time with a nylon or polypropylene PP brush thoroughly scrub the cement surface. Carefully check the grinding result, if necessary, be polished again. ? After the foundation curing period, with 85% commercial phosphoric acid / hydrochloric acid diluted to 10% concentration (1:10 watered), nylon or polypropylene PP brush thoroughly scrub the cement surface. At least 15 minutes until foam completely disappeared, repeatedly washed with water and immediately drained site (available push water or suction device). ? After the pickling is completed, to ensure cement foundation surface without any grease, dust, loose material and other debris. Processing 1.3 crack? Thoroughly clean up after cracks with caulk timber filled to flat. 1.4 expansion joint treatment? First air compressor to deal with clean joints. ? Then fill the joints to smooth the caulking material. 1.5 "bird bath nest" process? Evenly wipe the surface of ground water first, must be carried out on the ground temperature is low. ? Drained after an hour, covering any water at one yuan coin (commonly known as "bird bath nest"), you must first mark with chalk, crayons or avoid the use of oil-based pen. After? Be water at the completely dry, water-based adhesive patch to 托柏斯 "bird bath nest" to smooth (the ratio of its construction, refer to "TPA-103 water-based adhesive Tuobai Si" material description). 2.0 Use Material Products Hard acrylic cement foundation course requires the use of the following:????? Enhanced leveling layer of water-based primer coating surface coating paint line 3.0 enhanced water-based primer coating layer applied only Enhanced water-based primer. ? Use about 0.15kg / m. ? The actual amount varies depending on the flatness of the ground. 3.1 Description ratio? Can that can be used directly without dilution. 3.2 Usage notes? Choose lint roller coating primer. ? In roller coating material when should crossbar coating, to ensure a uniform to avoid the thick plot. ? Roller brush coating can not be applied at the switch. 3.3 drying time? In the ideal state construction 25 ℃ and 50% relative humidity, Tuobo Si enhanced water-based primer drying time is 4 hours. ? A leveling layer coating should be enhanced water-based primer before is not completely dry the coating in order to achieve the strongest adhesion. ? The lower the temperature, the higher the humidity, the longer the drying time of the coating. 4.0 leveling layer paint application? Tuobai Si before coating other coatings, it is recommended at least three leveling floor coating paint. ? Each use about 0.25kg / m (undiluted). ? The actual amount depends on the ground added sand flatness and thickness differ. Beijing Hang Yi Construction Co., Ltd.
