Concrete pouring requirement: the strength of the concrete floor design requirements ≥C25,2 meters by foot margin of error ≤ 3mm. ? 2, clean the floor: For new poured concrete, using trowel smooth, compacted, should conserve at least 15 days before sanding, white base and remove surface dust. For the old concrete floor or emery floor hardeners, clear material impact penetration surface oil, paint and loose structure, and then thoroughly clean the floor. ? 3, on the old ground is too dry, use clean water to fully wet concrete surface. ? 4, using the hardener pretreatment sufficiently wetted concrete surface, and kept moist for 1-2 hours. Can be applied by brush, roller or spray coating methods. If the local site dry period, additional material should be kept moist. During this period should be used like a brush, mop or roller tool constant friction surface, so that the hardening agent can more effectively penetrate into the concrete. ? 5, when high temperatures, surface hardeners due to the evaporation of water quickly becomes sticky, you can spray a small amount of water to dilute the thickened hardener, but the amount should not be excessive. ? 6, remove the remaining liquid: the use of plastic wiper or mop the remaining liquid surface clean, rinse with plenty of water can also be used, but need to be careful not to have water immersion phenomenon. ? 7, conservation: dry ground within walking distance of two days open, seven days before the conservation work should be put into use. Hardener ingredients penetrate gradually with the cement reaction, often using a wet mop cleaning to penetrate into the concrete surface to promote the reaction was continued inside the gel can be obtained earlier strength and gloss. ? 8, polishing: Finished ground after friction with the use of time will become more frequent and bright, but also can be used immediately after artificial mechanical polishing to obtain the effect of certain floor gloss.
