Repair tips! Color difference of exposed concrete is no longer a problem

In construction projects, plain concrete is favored for its unique texture and natural color. However, various factors in the construction process often lead to color differences on the concrete surface, affecting the overall beauty and quality. In the face of this problem, we have compiled a series of quick and effective repair tips to help you deal with it easily.

‌1. Analysis of the causes of color difference‌

First, clarifying the root cause of color difference is the first step to solving the problem. The color difference of plain concrete may be caused by various factors such as raw material differences, uneven mixing, improper maintenance, and changes in the construction environment. Through careful analysis, determine the specific cause and lay a solid foundation for subsequent repair work.

2. Preventive measures‌

‌Unify raw materials‌: Ensure that concrete raw materials, such as cement, aggregates, additives, etc., come from the same batch to reduce color differences caused by material differences.

‌Strict mixing control‌: Use advanced mixing equipment and technology to ensure that the concrete is mixed evenly to avoid local color differences.

‌Optimize construction technology‌: Reasonably arrange the construction sequence to avoid the impact of direct sunlight and sudden temperature changes on the concrete surface.

‌Strengthen maintenance management‌: Formulate a scientific maintenance plan to keep the concrete surface moist to prevent cracking and color differences.

‌3. Repair tips‌ ‌Surface treatment method‌: For slight color differences, grinding, polishing and other surface treatment methods can be used to make the concrete surface color uniform.

‌Chemical coloring method‌: Use professional concrete colorants to mix colors according to the color difference and color the concrete surface to achieve the purpose of repairing color difference.

‌Covering decoration method‌: Cover the concrete surface with a layer of decorative materials, such as tiles, paint, etc., which can not only cover the color difference but also improve the beauty of the building.

‌Partial replacement method‌: For areas with severe color differences that other methods cannot repair, consider replacing the concrete locally to ensure overall color consistency.
