Fast removal of thick coating such as old glue, epoxy, paint, in particular thick resins.
Creates slip-resistant finish on granite and marble, breaks down coatings prepares surface for application of new coating overlay, enhances the combination of floor and new layer material.
Lavina PCD grinding shoes for epoxy coating
Huanlong makes a series of diamond and PCD grinding shoes for Lavina, this 1/2 PCD is easy to remove epoxy coating, paints, glue and similar floor surface, it is faster and longer lifespan than diamond grinding shoes.

PCD Segment – 6 HolesTrapezoid PCD’s are great for thick coating removal, very aggressive. For best results remove bulk of coating without continued contact with concrete. Come back with an aggressive metal bond diamond segment and clean up any thin coating left behind. This will help preserve the life of the PCD segments.
Double Quarter Round PCD With 1 Segment Best Use For Epoxies, acrylics, paints, and thicker glues/mastics. Ideal for 1mm to 2mm thick coatings. Works well on both small single-head (PG 280) and medium planetary (PG 450/530) machines.

The Redi-Lock with 2×1/4 PCD & 1 Bar Segment is the go-to tool for removing medium-thick coatings where you want to balance speed with a controlled finish.
Compare to the 3X1/4 PCD, this 2-PCD version is slightly more aggressive because the machine’s weight is concentrated on two points instead of three.
1. Why Choose 2 PCDs instead of 3?
Higher Point Pressure: With only two 1/4 chips, each chip bites deeper into the coating. This makes it better than the 3-PCD version for slightly thicker or tougher materials that a 3-PCD might “skate” over.
Faster Cutting: It removes material slightly faster in most conditions because the chips are less likely to get “clogged” with debris, as there is more open space on the tool face.
2. The Stabilizing Bar (The “Wear Bar”)
Just like the other configurations, the 1 Bar Segment is essential here:
The Depth Gauge: It limits how deep the two PCD chips can dive. Without this bar, the 2×1/4 PCDs would likely “trench” the floor or chatter violently.
The Scratch Pattern: The bar is usually a coarse metal-bond diamond (around 20-30 grit). It grinds the floor while the PCDs scrape, which helps “clean up” the aggressive gouges and prepares the concrete for the next step of metal bonds.
