The right tool is the one matched to the machine, the material and the job. Tools like WerkMaster PCD coating layer stripping Tool (JOY-WM-PCD1R1) and WerkMaster PCD epoxy resin stripping Tool (JOY-WM-PCD1S1) are purpose-built for this work. The most suitable tool for stripping road tar, bitumen, and heavy black mastic from a concrete slab is a PCD (polycrystalline diamond) scraping tool—typically a half-moon or 1/4-circle PCD block mounted on a trapezoid or puck holder.

Bitumen, tar, and asphalt-based mastic are thermoplastic: they soften with heat and gum up normal diamond bonds.
Getting the spec right avoids a wasted order.
What to check before buying.
Tooling that fits and matches the bond runs noticeably better.
Key selection points.
For floors that mix bitumen with old epoxy resin glue, WerkMaster PCD epoxy resin stripping Tool (JOY-WM-PCD1S1) handles the glue layer residue that follows the tar.
Fit is the first filter - the rest is performance.
How the tool works.
Some flooring crews mist the floor lightly, though this creates grinding slurry and is optional.
Getting the spec right avoids a wasted order.
What to check before buying.
Tooling that fits and matches the bond runs noticeably better.
Key selection points.
If the old coating layer contains coal-tar epoxy resin (common on parking decks), inspect local rules: some jurisdictions classify it as hazardous and require licensed disposal.
Fit is the first filter - the rest is performance.
A: In short, For small areas yes, but it is slow and drives tar deeper into pores. A PCD grinder is far faster and leaves a cleaner slab.
A: The practical answer is, PCD can scuff soft concrete. Keep pressure light and follow with a 30/40 metal-bonded matrix pass to blend the surface.
A: For most jobs, Above 5 mm, score or mill the bulk first. PCD then strips the remaining film without bogging down.
A: In short, Heated bitumen releases fumes. Ventilate the area, wear a dust mask, and use a fine dust extractor. Stop open flames—bitumen is combustible.
