Selecting the right abrasive tools is a critical step in concrete floor grinding and polishing. Choosing the correct bond not only extends the life of your diamond pads and enhances floor gloss but also helps you effectively control costs and increase project profitability. 1. What is a Bond? The "bond" is the metal matrix that holds the diamond particles in place within the tooling. During the grinding process, the bond gradually wears away, continuously exposing fresh, sharp diamonds to maintain efficient cutting performance. Golden Rule for Bond Selection: Hard Floors → Use Soft Bond (Faster wear, continuous diamond exposure, prevents under-polishing) Soft Floors → Use Hard Bond (Slower wear, prevents over-cutting, extends tool life) If you are unsure of the floor hardness, we recommend using a Mohs hardness tester or conducting an on-site test grind. If testing is not possible, opting for a medium bond is the safest and most versatile solution. 2. Three Main Bond Types & Their Applications Bond Type Suitable Floor Types Key Characteristics Hard Bond New concrete, asphalt, dusty or abrasive substrates Wears slowly, protects against excessive abrasive consumption, ideal for softer or more porous surfaces Medium Bond Most common concrete types, refurbished floors, mixed substrates Highly versatile, consistent performance, the most commonly used and reliable choice for contractors Soft Bond Super-hard surfaces (e.g., terrazzo, heavily hardened concrete) Wears quickly, aggressive diamond exposure, prevents glazing and under-polishing on hard floors ⚠️ Warning: Using the wrong bond can lead to "glazing" (where the metal bond covers the diamonds, stopping them from cutting) or abnormal wear – both of which waste significant time and money. 3.

In concrete polishing, choosing the right diamond tool is half the battle won. Using the wrong tool not only wastes time and money but also leads to equipment wear and reduced efficiency.   For this XINGYI Abrasives Festival, we've prepared practical guides and exclusive offers for professional contractors to help you unlock the full value of every diamond tool you use.   1. Match the Bond to the Substrate   Hard Floors → Soft Bond   Soft Floors → Hard Bond   Precise matching ensures consistent diamond exposure and sharpness. A bond that's too hard will cause the tool to glaze and lose cutting ability; one that's too soft will wear out too quickly. Let the XINGYI team match you with the optimal tool set for smoother grinding and longer tool life.   2. Specialized Tools for Superior Results Instead of a "one-tool-fits-all" approach, specialized tools deliver the best outcome. XINGI offers a complete series of metal and resin bond tools designed for specific materials—whether it's concrete, terrazzo, epoxy coatings, or natural stone—delivering optimal cutting power and a superior finish.   3. Perfect Harmony Between Machine & Tool XINGYI provides a complete equipment lineup, from portable grinders to industrial machines, paired with our full range of diamond tools. This enables a scientific approach where "floor, machine, and tool" work in unison. Avoid excessive pressure; let the tool run smoothly to achieve a uniform, high-gloss finish.   �� Abrasives Festival Exclusive Offer Upgrade your tooling setup during the event and enjoy:   Exclusive package discounts   A $100 voucher for your next purchase   One-on-one configuration advice from our experts   Contact us today and let every floor you polish shine with professional brilliance.   XINGYI – Achieving Excellence in Every Grind.

4 Secrets Pros Use to Make Concrete Floors Shine Like Glass Ever wonder why some polished concrete floors look like flawless mirrors — while yours just looks… average? It’s not luck or photo filters. It’s the process. Here are 4 steps professionals never skip — follow them, and your floors will shine brighter, last longer, and leave your customers truly impressed. 1. Test the Concrete Hardness First No two floors are the same. Some are hard as granite; others are soft like chalk. Pros never assume — they test the surface hardness from the start. Choosing the right diamond bond is key: Hard floors → use soft bond diamonds Soft floors → use hard bond diamonds This saves your tools — and your budget. (Not sure how? XINGYI experts offer free guidance.) · 2.Repair Before You Polish Small cracks or chips might seem harmless now, but after polishing, they’ll stand out like scars. That’s why pros never skip concrete repair. Think of it like makeup before the stage — the better the base, the more stunning the final result. 3. Deep Clean — Don’t Skip It Old floors often hide oil, glue, or grime. These contaminants block densifiers and cause uneven coloring. Clean thoroughly first — only then can you achieve that smooth, mirror-like gloss professionals deliver. 4. Use the Right Machine & Tools Even top-quality diamonds won’t perform well with the wrong grinder. Experienced contractors rely on XINGYI floor grinders — engineered for balanced pressure, steady power, and perfect edge work. New to polishing?
