Concrete Grinding

Concrete grinding is planned around the condition of the slab and the next construction step. Removing a weak surface, correcting a local high spot and producing a decorative finish call for different scopes.

What concrete grinding is used for

Removing coatings, paint, sealers, mastic and glue before a new floor.
Opening the surface and producing the profile a coating needs.
Taking down high spots, lips at joints and trowel marks.
Exposing aggregate for polished concrete, salt and pepper or grind and seal finishes.

Equipment and dust control

Grinding is done with planetary or single-head grinders fitted with metal-bond diamond tooling chosen for the hardness of the slab and the material being removed. Edges and corners are worked with smaller hand grinders. Machines are connected to industrial vacuums with HEPA filtration so dust is captured at the source, which matters indoors and in occupied buildings. See dust-controlled grinding for how work is contained.

Grinding vs shot blasting

Grinding gives more control over flatness and is usually preferred for thin coatings, polished finishes and areas with edges and obstructions. Shot blasting is faster on large open floors and produces a rougher profile suited to thicker systems. Many projects use both.

Common questions

How much concrete does grinding remove?

Usually only the surface layer and any contamination. Deeper removal is needed only for heavy coatings, adhesives or damaged surfaces, and is planned in the scope.

Can you grind in an occupied building?

Yes, with dust extraction, containment and scheduling around the occupants. Noise and access are discussed before work starts.

Provide the floor area, access details and the intended next finish. We will identify repairs and perimeter work that need to be included alongside the main grinding passes.

This is part of our surface preparation & grinding service. Related work: diamond grinding, dust-controlled grinding and concrete polishing.

FAQ

My floor is old and stained. Can it still be coated?

Usually yes. Stains and old patches sit at the surface, and grinding takes that layer off before anything is applied.

What we check for underneath is moisture and structural cracking, since those decide the build rather than the appearance.

Why is grinding important before sealing?

Grinding removes contamination, levels imperfections and creates the surface conditions required for proper sealer penetration and long-term adhesion performance.

Related: grind and seal systems.

Why is grinding important before urethane flooring installation?

Grinding creates the concrete profile required for strong mechanical adhesion between the flooring system and the substrate.

Why is concrete grinding important before installation?

Grinding creates the concrete surface profile required for mechanical adhesion. Without proper preparation, coatings may experience reduced bond strength and shortened service life.

Why is concrete grinding important before epoxy installation?

Grinding creates the concrete surface profile required for proper mechanical adhesion. Without preparation, coatings may fail due to weak bond development or unstable substrate conditions.

Related: epoxy flooring systems.

What preparation does Epoxy Boss perform before polishing?

Preparation may include industrial diamond grinding, coating removal, adhesive removal, crack remediation, joint repair, surface correction, densification procedures and contamination removal depending on slab condition and project requirements.

Related: concrete polishing.

Why is concrete grinding important for polished concrete?

Grinding removes surface contamination, levels imperfections and creates the foundation required for densification and polishing. Proper grinding progression directly affects clarity, reflectivity, durability and final surface consistency.

Does grinding help identify moisture-related flooring issues?

Yes. Proper preparation often exposes moisture-related substrate conditions, contamination and concrete defects before flooring installation begins, allowing corrective measures to be implemented when necessary.

Can grinding fix uneven concrete?

Grinding can help reduce high spots, smooth transitions and improve surface consistency depending on the severity of the slab condition. More extensive leveling systems may be required for heavily damaged substrates.

Related: surface flattening and floor leveling.

What does grinding remove from concrete?

Grinding may remove:

old coatings
epoxy residue
adhesives
paint
contamination
weak concrete layers
surface imperfections
uneven sections

What is concrete grinding?

Concrete grinding is a mechanical preparation process that removes contamination, levels uneven surfaces and creates the profile required for flooring installation and long-term adhesion performance.
