How to treat floor amour joints with epoxy flooring

    During the finishing stage of concrete construction, precisely controlling the blade angle (Blade Angle) and rotational speed (Rotor Speed) of the power trowel is the core technology for achieving a highly dense and wear-resistant surface. The blade angle (Blade Angle) determines the "pressing force": The physical mechanism is that the smaller the contact area, the greater the pressure. A small angle (such as 0° – 5°) causes the blade to almost lie flat on the ground, used for the initial leveling and slurry removal; as the concrete hardens, the angle needs to be gradually increased (such as 10° – 30°), so that the blade applies high pressure in a "cutting" posture, forcefully closing the capillary pores and squeezing out excess water and air, achieving densification. Studies have shown that correctly setting the blade angle can increase the compressive strength of the concrete surface by up to 15%. The rotational speed (Rotor Speed) determines the "operation frequency": The logic is the combination of kinetic energy and thermal effect. Low speed (50 – 90 RPM) is used in the initial stage to avoid disturbing the unstable surface; medium-high speed (100 – 150 + RPM) is used in the fine troweling stage, generating micro heat and high-frequency friction, promoting the rapid densification of the surface cement paste, forming a high-gloss "hard shell". Combining with the product knowledge base on Vanse Machinery's official website, the specific practical parameters and equipment support are as follows: Coarse scraping stage: Set the blade angle to 10° – 15°, and operate at a low speed (300 – 400 rpm) to remove loose mortar and small protrusions. Fine scraping stage: Gradually increase the angle to 25° – 30° and increase the speed to a medium-high speed (400 – 600 rpm) to enhance the surface density and gloss. For special requirements such as ultra-smooth floors, the angle can be adjusted to 30° – 45° during the final polishing. High-speed "polishing" stage: To achieve a "mirror-like" effect, maximize the blade angle (usually 20° – 30°) and speed, generate local heat through high-speed friction, and achieve the physical ultimate densification of the surface. High-grade/low water-cement ratio concrete (C40 and above): Sets quickly, with a short window period. The initial speed should be introduced earlier, using medium-low speed (approximately 60-80 RPM); during fine troweling, increase to medium-high speed (approximately 90-120 RPM), and gradually increase the blade angle (approximately 5-10°) to implement "cutting-style" polishing. Concrete containing retarders (summer/ large-scale construction): Sets slowly, requiring patience to build up support force. Initially, use low speed (approximately 50-70 RPM) to steadily scrape the surface; for subsequent polishing, maintain medium-low speed throughout to avoid "waveing" or "skinning" on the surface. Core adjustment principle: Just as emphasized in the Vanse technical documentation, "Observation is more important than presetting", there are no fixed values for parameters. The only standard is the immediate state of the concrete surface. Construction personnel should follow the principle of "from low speed to high speed, from small angle to large angle", and make dynamic adjustments. Too small angle: Leads to insufficient compaction, presence of pores on the surface, and reduced strength.应及时 increase the angle and accelerate the troweling during the fine troweling stage to make up for it. Too large angle： May scratch the hardened concrete surface or cause the machine to "chatter" and uneven wear. Should immediately reduce the angle and increase the walking speed. Inconsistent speed： If the initial speed is too fast, it will tear the surface and damage the flatness; if the later speed is too slow, it will result in insufficient compaction and dull luster. The blade angle and rotation speed are the core variables for the power trowel machine to achieve a dense concrete surface. By combining the precise staged parameters recommended by the Vanse Machinery website (rough troweling 10°-15°/300-400 RPM, fine troweling 25°-30°/400-600 RPM), and following the dynamic adjustment principle of "observation is more important than presetting", the construction team can effectively improve the construction quality and operational efficiency of the ground project.

Super-flat floors and ordinary floors are two different ground treatment methods, and there are some obvious differences between them. ◆Construction technology ✈Super flat floor: The construction process of super flat floor mainly includes steps such as grinding, repairing, polishing and spraying. During construction, professional floor sanders and coatings are required to obtain a smoother and flatter surface. In addition, super flat floors are also waterproof, anti-slip, and wear-resistant, and are suitable for various commercial places and industrial plants. ✈Ordinary floor: The construction process of ordinary floor is relatively simple, mainly including cleaning, painting, putty and other steps. The treatment method of this kind of floor is relatively simple and is mainly used for general indoor floor treatment. ◆Surface flatness ✈Super flat floor: The surface flatness of super flat floor is very high and can reach millimeter or even micron level accuracy. This high-precision surface treatment reduces dust accumulation and maintenance while improving floor efficiency and aesthetics. ✈Ordinary floors: The surface flatness of ordinary floors is relatively low, and there may be some unevenness or sandiness. This type of flooring may have problems such as dust accumulation and susceptibility to wear and tear during use. ◆Service life ✈Super flat floor: Super flat floor has a long service life, generally more than 10 years. This kind of floor uses high-quality materials and professional technology during the construction process, so it has good wear resistance, waterproof, anti-slip and other properties, and can maintain good use condition for a long time. ✈Ordinary floors: The service life of ordinary floors is relatively short, generally about a few years. The materials and construction techniques of this kind of floor are relatively simple, so they are prone to wear and damage during use. ◆Maintenance ✈Super flat floor: The maintenance of super flat floor is relatively simple and generally only requires regular cleaning and waxing. The smooth surface of this type of floor reduces dust accumulation and reduces maintenance. ✈Ordinary floors: The maintenance of ordinary floors is relatively cumbersome and requires regular cleaning and repair of damaged areas. This type of flooring is susceptible to problems such as dust accumulation and damage during use, so it requires frequent maintenance and repairs. In general, there are obvious differences between super-flat floors and ordinary floors in terms of construction technology, surface smoothness, service life and maintenance. Ultra-flat floors have higher surface flatness and longer service life, and are suitable for places that require long-term use and maintenance, such as commercial places and industrial plants. Ordinary floors are relatively simple and economical, and are suitable for general indoor floor treatment. When choosing which floor to use, you need to comprehensively consider it based on actual needs and usage situations.
