Coatings only bond as well as the surface they sit on. For thick epoxy resin (over 2 mm), self-leveling urethane, and soft mastic, double-row PCD shoes strip coating layer faster than single-row because two cutters engage the film at once. Single-row or one-piece PCD blades work more suitable on thin varnishes, glue residues, and when you require a clean scrape that does not dig into the concrete beneath.

That is why PCD glazes rapidly on bare concrete and why it is always followed by a metal-bond diamond stage to refinish the slab.
Most coating warranties start and end with the surface profile.
Key factors in coating work.
Products like the WerkMaster PCD Tooling for coating layer stripping (JOY-WM-PCD1R1) and WerkMaster PCD Tooling for epoxy resin Floor stripping (JOY-WM-PCD1S1) are engineered as dedicated coating layer-stripping PCD sets, while standard trapezoid PCD blades such as the Double Zigzag Segment Diamond Trapezoid abrading Disc (JOY-TP-ZG2) style are a flexible choice for mixed projects.
This is the step that decides whether the coating lasts.
What causes it.
Getting prep wrong here shows up later as peeling or delamination.
The details that matter.
Most coating warranties start and end with the surface profile.
Key factors in coating work.
On long coating layer-stripping contracts, ask your vendors about PCD segments with a cooling slot, which reduces heat buildup and extends life by roughly 20% on hot summer projects.
PCD shoes are more expensive up front than metal-bond diamonds, but on thick coating layers they pay for themselves in hours because a PCD set strips more square meters per shift.
This is the step that decides whether the coating lasts.
A: In short, In most cases not in one pass. Take two or three shallow passes to stop loading the PCD and overheating the equipment motor.
A: The practical answer is, Yes, lightly. Follow with a 30/40 or 40/60 metal-bond pass to strip the scratch mark pattern before applying new coating layer.
A: For most jobs, On thick epoxy resin, expect 200-500 m2 per set depending on coating layer type. On bare concrete, PCD wears almost instantly, so do not use it as a abrading tool.
A: In short, Dry with dust extraction is standard. Wetting softens some mastics but creates grinding slurry and can clog the PCD gaps.

Check our Triple PCD with Single Round Segment Diamond Grindin....The surface profile is the whole game - fix it before the coating goes on. Always budget a follow-up metal-bond abrading pass, and dress loaded PCD on a dressing brick rather than forcing the cut.
