Concrete Grinding Newcastle: Floor Prep, Levelling and Trip Hazards
Pulled up carpet and found a slab covered in glue? Got a lip in the path someone keeps tripping on? Both are jobs for concrete grinding in Newcastle. Tell us what is on the concrete and what is going over it. Book it with us and we'll send a local grinding specialist to quote.

What grinding jobs can we help with?
Glue and adhesive removal
Carpet glue, vinyl adhesive and tile bedding taken back to clean concrete.
Paint and coating removal
Old paint, epoxy and failed sealers stripped so a new finish will bond.
Floor preparation
A flat, clean, keyed surface for tiles, vinyl, timber, epoxy or polished concrete.
Concrete floor levelling
High spots ground down and low areas filled with levelling compound.
Trip hazard grinding
Lifted joints and lips in paths, driveways and car parks ground flush. If the slab's cracked through as well, that's concrete repairs.
Garage and shed floors
Rough or stained slabs ground ready for a seal or a coating.
What's on your floor, and what happens to it?
We ask what you're starting with. It changes the tooling, the time and who we send.
| What's there now | What the operator does | Worth knowing |
|---|---|---|
| Carpet or vinyl glue | Grinds it off with diamond tooling under vacuum extraction | Soft, sticky glues clog tooling and take longer than hard ones |
| Tile adhesive or bedding | Several passes, often after the tiles are lifted | Tell us if the tiles are still down |
| Paint or epoxy | Coating-removal tooling, then a clean-up pass | Thick epoxy is slower than a coat of paving paint |
| A lip between two slabs | Grinds the high side down to a gentle ramp | It fixes the trip, not the cause of the lift |
| Hollows and uneven areas | Grinds the highs, then pours levelling compound in the lows | Needed before vinyl, timber or large tiles |
Grinding, levelling or polishing: which do you need?
Easy to ask for one when you need another. Here's how to tell them apart.
- 01
Grinding
Takes material off. It cleans, flattens and prepares the slab. On its own it leaves a matte, slightly rough surface.
- 02
Levelling
Grinding the high spots and filling the low ones so a floor covering sits flat.
- 03
Grind and seal
A grind, then a clear sealer. A finished floor for less than polishing.
- 04
Polishing
Grinding carried on through finer grits until the concrete itself shines. That one has its own page: polished concrete.
What the job changes
A grind takes a stained, dusty slab back to clean concrete. Sealed afterwards, it stops dusting, wipes clean and gives a coating or floor covering something sound to stick to.
Drag the handle on the picture to compare before and after.
Ask how dust will be controlled before the job starts. SafeWork NSW publishes the rules on silica dust. For jobs over $5,000, look up the contractor's licence with Building Commission NSW.

What affects the cost of concrete grinding?
Grinding is usually priced by the square metre, and these are the things that set the rate.
- Area
- Small jobs often carry a minimum charge, because the machine and vacuum still have to turn up.
- What's being removed
- A light clean-up pass is quick. Thick glue or epoxy isn't.
- How flat it has to be
- Tiles forgive more than vinyl plank or polished concrete.
- Edges and corners
- Big machines stop short of walls. Edge work is done by hand and adds time.
- Access and power
- Stairs, upper floors and sites without suitable power all slow things down.
- Levelling compound
- Priced on depth and area, on top of the grinding.

What is the difference between grinding and polishing?
Grinding takes material off: old glue, coatings, high spots and trip lips. Polishing carries on from there with finer and finer passes until the floor has a sheen. Grinding is often preparation for another floor covering. Polishing is the finished floor. Stopping short of a full polish is an option too: see honed vs polished concrete.
Is concrete grinding dusty?
It should not be. Grinding concrete creates silica dust, which is a regulated health hazard in NSW, so contractors use vacuum extraction or water to control it. Ask how they manage dust before they start.
Can I stay in the house while it's done?
Usually, though it's noisy and the room being worked on is out of use. Tell us if people or pets will be home so the contractor can plan around it.
How flat can an old slab be made?
Flat enough for most floor coverings. Grinding takes down the high spots and levelling compound fills the low ones. The contractor will check it with a straight edge and tell you what's realistic.
Will grinding fix a trip hazard for good?
It takes the lip off. If a tree root or sinking ground caused the lift, it can come back, so the cause needs dealing with too. Our guide to tree roots lifting concrete in Newcastle covers that.
Do you take small jobs?
Send it through. Some grinders will do a single room or one trip hazard, usually with a minimum charge.
