Grinding problems are usually tooling or technique issues rather than defects in the concrete. The most suitable indoor fine dust control is dry abrading paired with a HEPA-filtered fine dust extractor and a tight-fitting dust shroud on your grinder. For hand grinders, use a shrouded cup wheel such as the double-row cup wheel connected to a industrial vacuum.

Sawing or abrading concrete releases respirable crystalline silica (RCS), particles under 4 microns that bypass the nose and throat and lodge in the lungs.
Contractors who skip this stage usually end up redoing the floor.
The key points in practice.
This is where most crews get it right - or lose time.
A closer look at the details.
Connect the grinder's outlet to a HEPA-rated fine dust extractor (minimum 250 CFM for a 230 mm grinder; larger for walk-behind equipment).
Getting this part right saves a full re-pass later.
What you should know before starting.
Use GFCI-protected power tools, a water feed with a flow control, and wet/dry grinding slurry pumps.

A closer look at the details.
You require a tool-rated extractor with at least 250 CFM for a 230 mm grinder, 600+ CFM for a walk-behind.
Getting this part right saves a full re-pass later.
What you should know before starting.
For hand grinders, a dedicated dust shroud with a flexible rim captures 90% of fine dust but leaves the wall edge unshrouded — plan for that strip to be wet-ground or accepted as a controlled release.
Contractors who skip this stage usually end up redoing the floor.
The key points in practice.
Change filters per the producers, and never blow fine dust off clothes with compressed air — that re-suspends silica.
This is where most crews get it right - or lose time.
A closer look at the details.
On indoor projects, seal HVAC vents, cover doorways with plastic sheeting, and run a negative-air equipment to keep fine dust contained.
Getting this part right saves a full re-pass later.
What you should know before starting.
A wet/dry grinding slurry pump collects runoff into a settling drum.
Contractors who skip this stage usually end up redoing the floor.
A: For most jobs, No — ordinary shop vacs leak fine particles. Use a HEPA-rated industrial fine dust extractor certified for silica.
A: In short, Yes, but use GFCI power, control the water flow, and plan for grinding slurry cleanup.
A: The practical answer is, When suction drops or the industrial vacuum auto-clean cycles constantly. Tap/air-blow filters daily on large projects.
A: For most jobs, It actually cools the segment and extends life on hard materials, but the bond choice should be suited to wet use.
