In most cases, it is not recommended to sand the dried concrete curing compound. The compound is specifically designed to create a film on the concrete surface, which acts as a barrier to moisture evaporation. Sanding the cured compound would remove this film, compromising its effectiveness in retaining moisture for proper curing.
Additionally, sanding the cured compound may result in an uneven surface texture, which can negatively impact the final appearance and finish of the concrete. The compound is often formulated to provide a smooth surface, so sanding it could create irregularities and rough patches.
Alternative Options
If the concrete surface requires sanding to achieve the desired smoothness or aesthetics, it is best to postpone applying the curing compound until after the sanding process is complete. Sanding is typically done once the concrete has fully cured, and any imperfections or inconsistencies can be easily rectified. Once the sanding is complete, the concrete can be thoroughly cleaned to remove any debris or dust, and then the curing compound can be applied according to the manufacturer’s instructions.
Concrete curing compound plays a crucial role in the construction process, ensuring proper curing and enhancing the strength and durability of concrete. While the compound cannot be sanded once it dries, it offers numerous benefits during the curing phase. It is essential to plan the sequence of the construction steps carefully and determine when to apply the curing compound in order to achieve the desired smoothness and appearance of the final concrete surface.
