Proper concrete surface preparation is essential before applying epoxy, polyurethane, or other floor coatings. Oil, dust, old coatings, adhesives, and weak concrete can reduce adhesion and lead to peeling or coating failure. A properly prepared concrete floor should be clean, dry, sound, and have the correct surface profile. 1. Inspect the Concrete Surface Before starting, check the floor for: Old coatings or adhesives Oil and surface contamination Cracks or damaged concrete Uneven areas Moisture issues The condition of the floor will determine the best concrete floor preparation equipment for the job. 2. Choose the Right Surface Preparation Method Concrete Grinding Concrete grinding is one of the most common methods for epoxy floor preparation. A floor grinder with the correct diamond tooling can remove coatings, adhesives, and surface imperfections while creating a suitable surface for the next flooring system. For general floor preparation and coating removal, the XINGYI GX510 Planetary Concrete Floor Grinder is designed for demanding surface preparation applications. For edges, corners, and tight spaces that larger grinders cannot easily reach, the XINGYI GX250 Edge Concrete Grinder provides a compact solution. Shot Blasting For larger areas or projects requiring a more defined Concrete Surface Profile (CSP), a concrete shot blaster can efficiently remove surface contaminants while profiling the concrete. XINGYI offers dedicated concrete shot blasting equipment for professional surface preparation and coating removal applications. Scarifying For thick coatings, damaged concrete, or more aggressive material removal, a concrete floor scarifier may be the better choice. Scarifying removes material more aggressively than standard grinding and can create a deeper surface profile when required. 3. Achieve the Correct Concrete Surface Profile Removing the existing coating is only part of the process. The prepared concrete must also meet the CSP requirements specified by the coating manufacturer. A surface that is too smooth may reduce adhesion, while excessive profiling can increase coating consumption. 4. Control Dust and Clean the Floor Dry concrete grinding can generate significant dust. Using a properly matched industrial vacuum cleaner or dust extractor helps control airborne dust and keeps the prepared surface cleaner. XINGYI currently offers industrial vacuum solutions designed to work with floor grinding equipment. Before applying epoxy or another coating, make sure the concrete is: Clean. Dry. Sound. Properly profiled. Good coating performance starts with good surface preparation.

Every June, XINGYI hosts its global Dust-Free Month to promote cleaner and healthier working practices in the flooring industry. In 2026, the campaign returns for its 8th edition with the theme “Breathe Easy: Less Dust, More Health.” Cleaner Jobsites Start with Better Dust Control Concrete grinding produces fine dust that can affect both jobsite conditions and worker health. Since 2019, XINGYI has continued to promote effective dust-control practices through professional equipment and practical solutions. This year’s featured product, the IVC-V3A Automatic Filter-Cleaning Vacuum, uses an automatic pulse-jet reverse-cleaning system to maintain efficient dust collection with fewer interruptions. Throughout Dust-Free Month, XINGYI will host live demonstrations and online sessions, along with special offers on selected dust extraction equipment. Less dust. Safer work. Healthier jobsites.

This month, Xingyi completed batch shipments of two self‑developed smart floor grinding robots – the AT8 and AT16 – totaling 11 units to Asia‑Pacific, North America, and Europe for various overseas projects. The AT8is equipped with the Atlas FSG autonomous grinding system, while the AT16 features the TrueFlat high‑precision leveling system. Both leverage Xingyi’ s proprietary Atlas intelligent platform – combining laser‑vision dual navigation for autonomous obstacle avoidance (columns, steps, potholes) and route planning, with laser‑gyro‑linked ultra‑flat grinding. The systems maintain consistent grinding pressure and flatness, significantly reducing manual oversight and skill requirements, while eliminating common defects like missed spots, over‑grinding, and wavy surfaces. They deliver both efficiency and quality across medium‑to‑large projects. These two models precisely address different project scales. Xingyi will continue to invest in smart grinding technology, providing efficient and standardized solutions for flooring professionals worldwide.
