Plaster and grout the mixed high efficiency repair mortar of Shuoya Building Materials at the repair site.
The one-time construction area of efficient repair mortar should not be too large, and should be staggered in sections and blocks.
If bubbles appear, they shall be punctured and compacted, and the surface shall be dense.
5.
When the surface thickness of the facade or top surface is greater than 10mm, the construction shall be carried out in layers.
When efficient repair mortar is used as the overall surface course, the thickness shall not be less than 3mm.
The overall surface course of concrete or masonry structure facade and steel structure surface shall be carried out in two times, and the interval between each time shall not be less than 24 hours.
During layered construction, the reserved joints shall be staggered.
The interval between repair or repair and staggered construction shall not be less than 24 hours.
First pour the water into the mixing bucket, then slowly add the efficient repair mortar of Shuoya Building Materials, mix with the electric mixer to form a uniform paste without particles, and then wait for five minutes to mix again.
Evenly brush interface treatment agent twice on the surface of concrete base course.
The thickness of each layer shall be 5-10mm.
Requirements and treatment of base course: the surface of base course shall be flat, rough and clean, free of oil stain, floating ash, sand, hollowing, cracks, etc., and shall be flushed and wetted with high-pressure water before construction, but no ponding is allowed.
4.
The prepared slurry shall be used up within 0.5 to 1 hour.
Shuoya Building Materials shall be plastered immediately after the efficient repair mortar is paved.
2.
Slurry mixing: powder: water=4:1 (weight ratio).
If the repair thickness is greater than 50mm, it shall be treated in layers.
B.
3.
It shall be leveled at one time and shall not be plastered repeatedly.
According to the site environment, the area of each block shall not be greater than 10-15m2.
When bonding the interface, the interface treatment agent of Shuoya Building Materials can be used in advance.
The next layer can be constructed only when the previous layer touches…
