Water paint for the joining said that the scraping putty construction according to the process flow construction:

    1, the basic level processing: cast-in-situ concrete walls, due to the floor, all sorts of reasons, such as material, isolating agent wall roughness is bad, often porosity, voids, pits, Yin and Yang Angle unidiomatic and bulge phenomenon, so ask convex points carved mill, concave TianPingBuJi. For precast concrete floor board, board seam basic course, must be brushed by specially-assigned person with steel wire, float sand grain, knot in one's heart, dirt and other sundries on the surface clear. The cement mortar paper gluten grey surface layer requires the surface base dry, solid and clean (no floating soil oil) can be.

    2, grass-roots repair: after the clean up concrete roof and slab joint, the larger defects such as honeycomb parts use gypsum putty scraper fill compaction of the steel, horizontal wipe up blow again (surface smooth top surface can not scratch). Gypsum putty mix ratio (weight ratio) is gypsum: emulsion: cellulose aqueous solution (concentration 5%)= 100:5 ~ 6:6 0. Brush the caustic soda solution: brush with 5% caustic soda solution twice, if brush with 10% caustic soda solution once. Wash with clean water immediately after brushing, dry before proceeding to the next procedure.

    3, coating binder (SAP) : in blow be bored with child before spraying glue, coating must be uniform and shall not have leakage spray glue mixture (weight ratio) for water: emulsion = 100:15 ~ 20. Great white putty: shave is putty with sheet steel scraper scraping back and forth, if pay attention to the up and down or so, between two scraper to clean, not allowed to keep floating putty, blow be bored with child to prevent on or in sand and other debris. White putty mix ratio (weight ratio) is large white powder: talc powder: cellulose solution (concentration 5%) : emulsion = 60:4o: 75:2 ~ 4.

    When scraping putty, do not pollute the ground, doors and Windows, glass and other completed sub-projects. 2. After the completion of scraping putty, it shall be properly protected and shall not bump against and contaminate the walls.

    You must wear a safety helmet when entering the construction site and wear a safety belt when necessary. It is strictly prohibited to wear bare arms, bare chest, slippers or bare feet when entering the construction site.
