How to use power trowel

    Ensuring the uniform distribution of wear-resistant aggregates (such as corundum and alloy aggregates) is crucial to preventing color differences, peeling, and uneven wear resistance in floor coatings. Quality control should be implemented throughout the entire process, from "base layer treatment" to "mechanical finishing." The following are the core control methods for achieving uniformity: Do not rely solely on experience for random spreading; instead, adopt **"grid management."** Grid division: Based on the total amount used (e.g., 5 kg/m²), divide the construction surface into several equal areas. Quota placement: Pre-place the corresponding weight of aggregate in the center of each area to ensure consistent consumption in each grid cell. The "two-stage application method" effectively re pairs gaps left after the first application. First application (2/3 of the total amount): Applied when the concrete is initially setting (footprint indentation of approximately 5mm), utilizing the bleed water from the base layer to moisten the aggregate. Second application (1/3 of the total amount): After the first application is finished and smoothed, a reinforcing application is performed in a perpendicular direction, focusing on areas with lighter color or sparser aggregate. Mechanical Spreading Machines: For large-area construction, the use of automatic spreading machines is recommended. Compared to manual application, mechanical spreaders can precisely control the amount of material applied per square meter through rotational speed and travel speed, greatly improving consistency. Manual Assistance: When spreading manually, use a "scattering" motion rather than "pouring," and ensure the material is distributed evenly. Edge Prioritization: In areas difficult for large machinery to cover, such as column edges and wall corners, manual application of extra material and manual compaction should be performed first. Joint Treatment: At construction joints, the application amount should slightly overlap to ensure that the hardness and flatness of the joint area are consistent with the main surface. Avoid strong winds: During indoor construction, doors and windows should be closed to prevent drafts that could cause fine aggregates to deviate during placement, resulting in localized areas with insufficient material. Strictly prohibit adding extra water: If the aggregate is locally too dry, direct watering is strictly prohibited. The slurry generated by the power trowel should be used for wetting; otherwise, it will lead to reduced surface strength and color differences.   Quality inspection tips: After spreading, assess the consistency of the color (checking for light or dark patches) and the balance of moisture content by visual inspection. If localized areas appear lighter in color, it usually indicates an excess of aggregate or insufficient moisture in that area. Mechanical troweling to bring the mortar to the surface should be performed immediately.   Note: The parameters provided in this document are for reference only and are not mandatory.
