How to repair and prevent small cracks in imprinted concrete projects?

When working with imprint concrete, it's not uncommon for small cracks to appear along the edges, corners, or within intricate rock-like patterns. This issue often arises due to rapid drying conditions, especially under direct sunlight or windy environments. Concrete that absorbs more solar heat—especially darker hues—can dry unevenly, leading to stress fractures. Addressing these cracks promptly is essential to maintain the aesthetic integrity of your project. One effective solution is to employ colored cement slurry or specialized color patches. Many reputable color curing suppliers provide pre-mixed color patches tailored to match standard palettes, making them ideal for filling and repairing such cracks. Alternatively, some contractors repurpose leftover sand from their color curing agents as makeshift patching material. Our team recommends opting for wetter color patch solutions, which typically involve a 1:1 mix of polymer and water for optimal adhesion. To apply, use a wooden tongue depressor or simply wear gloves to spread the patch material directly into the cracks. Afterward, gently soften the edges with a damp rag or sponge to ensure seamless blending with the surrounding surface. Allow the patch to cure undisturbed for at least 24 hours before inspecting the results. For larger projects or persistent issues, consider consulting with a professional contractor who can assess the situation and recommend additional measures like applying sealants or reinforcing vulnerable areas. Prevention is always better than cure, so maintaining consistent moisture levels during the curing process can significantly reduce the likelihood of future cracks.

Rotor Pump With Water-proff Cover

We are a world-leading technology-based enterprise focus on R&D and manufactures non-Newtonian fluid conveying equipment. We specialize in rotary pumps, homogeneous pumps and grinding pumps. We have obtained 11 invention Patents and 46 practical patents, and won many national honorary titles.


Twin-rotor lobe pump are multi-functional and bi-directional positive displacement pumps, produced with fine technology. These products use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise a directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.


Rotor pump with water-proff cover: The pump is equipped with a detachable protective cover for the whole machine, and the material is S.S., it can protect the motor, coupling and other parts from corrosion during on-site cleaning.
