Zx self-leveling cement 15042472235 Wei Uses: home improvement recommended for the preparation of self-leveling cement paving wooden floors, carpets, tooling process is recommended for self-leveling cement screed PVC rubber flooring substrate. As well as leveling epoxy coating requirements or the requirements of the base or other dust-proof requirements of the ground. Such as: residential, office buildings, hospitals, shopping malls and other ground, pollution-free green product. Construction Description: (a) Primary treatment: 1, the primary strength of concrete before construction shall ≥C20, rugged place, cracks and holes should be pre-treated smooth, then scattered debris cleaned substrate surface, the surface must be hard , smooth and clean. 2, the grass wet concrete surface water and ensure no attached water pouring front layer. 3, ordinary Portland cement in the construction of new concrete base required 21 days after the new self-leveling concrete base construction, sulfur cement construction should be carried out after the completion of seven days before leveling construction. (Ii) for self-leveling cement 1, when a small area or road construction, available small electric mixer (200 to 500 rev / min), and stirred in a barrel, stirring once every full package material required; large-scale construction, Available high-speed mixer mixing, pumping method of construction with mortar. 2, the amount of water into the bucket, the stirrer stirring slowly adding a self-leveling cement bag (preferably added over 1 minute), for 4 to 5 minutes, resting for about 1 minute, stirring again to No group can even paste. 3, under cold conditions, to use warm water (not more than 40 ℃) and stirred. Mortar maintained at a temperature above 5 ℃. (C) pouring and leveling: 1, mixing good self-leveling cement poured, spread evenly, with a special scraper tooth mouth to control the thickness, the thickness of the construction product ≥3mm, a construction thickness of 3 ~ 30mm, the reference amount 1.6kg / m / mm. 2, construction workers can be put into the construction ground spikes, teeth mouth with a surface layer of mortar Calibrating scraper to remove uneven convergence at the dump and maintain the desired thickness. 3, with a deflated gently rolling roller to eliminate air bubbles generated when stirred. 4, mixing a good self-leveling cement should be used within 35 minutes. (D) curing: under normal temperature conditions according to the general mortar conservation, high or low temperature to be taken watering wet or covered with sacks, mats and other measures to conserve one to three days after the initial case hardened. Severe traffic ground maintenance required 3 days before passage. Technical indicators: compliance with JC / T985-2005 standard technical specifications packaging and storage: 1, 5 ℃ ~ 35 ℃ ventilated dry warehouse storage, unopened shelf life of six months. 2, packaging specifications 20kg / bag.
