usage method
Base treatment:
one The surface of the base course shall be clean, dust-free, oil-free and free of chemical corrosion medium residues. The surface of porous materials shall be soaked with water in advance, and the surface of steel base course shall be cleaned of floating rust.
two . It must be used first if there is leakage Plugging agent Conduct treatment to better keep the base surface wet until there is no open water, so as to achieve better construction effect.
Material preparation:
one Pour the glue into the bucket first, and then according to the glue: powder =1 ： four Add the powder slowly while stirring until it is even and free of caking.
two Mechanical mixing or manual mixing can be used, and the prepared mortar shall be 2-3h Used up in.
Construction and maintenance:
one , using EC When polymer repair mortar is used as the overall surface course, the thickness shall not be less than 3mm 。 When the one-time construction area is large, construction joints shall be reserved or staggered construction shall be carried out. The area of each piece should not exceed 10-15m2, It depends on the site environment. The gap time for patching or staggered construction shall not be less than 24h 。
two . When making the overall surface course on the facade of concrete or masonry structure and the surface of steel structure, it should be done in two times, and the interval between each time should not be less than 24h 。 When the later plastering is carried out, it shall be leveled at one time and repeated plastering is not allowed.
three The ambient temperature for the construction of this product is 10-30 ℃, not lower than five The raw materials shall not be polluted by moisture, rain, sunshine and sundries.
four This product is not suitable for construction in rainy days and freezing days. If construction must be carried out in winter, necessary anti freezing measures shall be taken , This product should be mixed and used at any time. It is not allowed to mix too much materials at one time, and each time the materials should be mixed in 2-3h Used up in.
