High speed railway concrete component defect Concealer defect color difference restoration protective coating

  Concrete color difference repairing agent is also a concrete protective agent
While providing overall protection, it can effectively solve the phenomenon of different colors of concrete surface without changing the appearance of fair faced concrete, and still retain the inherent natural and simple style of concrete surface, so as to make the color of concrete surface uniform
At the same time, it can cover the micro cracks on the concrete surface, increase the overall beauty of the concrete surface, improve the durability of the structure, protect the appearance of fair faced concrete buildings, bridges, concrete components and high-speed railways, and cover defects and cracks
1
Shielding: flat color, covering defects and microcracks, so that the concrete components have a good and unified appearance; 2
Protection of concrete structure: waterproof and anti-corrosion to improve the service life of concrete structure; 3
Water based, tasteless, non combustible, harmless to human body, belonging to green environmental protection building materials; 4
It is not easy to fall off and decolorize, and has good weather resistance; 5
Simple construction, convenient operation, ready to use after opening the cover 1 Base course requirements: if the concrete has wide cracks and defects, it shall be repaired first
