Garage Floor Screed — Flat, Coating-Ready Floors
Old garage slabs are rarely flat, often dusty and usually patched. We lay a fresh pumped screed over them in a single morning, so the coating you put on top has something worth bonding to.

Most garage enquiries start the same way: the slab is uneven, it sheds dust, and the owner wants a proper finish — an epoxy or polyurea coating, rubber tiles, or just a floor that sweeps clean. Painting straight onto a tired slab rarely lasts, because every dip, crack and patch shows through and the coating has nothing sound to grip.
Our answer is a pumped liquid screed laid over the existing floor. Where the old concrete is sound we bond to it from 30mm. Where it isn't, or where you want the space warmer, we go unbonded at 50mm over insulation and a membrane. Either way the finished surface comes out flat enough for two-pack coatings with no extra levelling compound.
This page is about garages kept as garages, workshops and EV bays. If the garage is becoming a bedroom or office, the build-up changes — see our garage conversion guidance linked below.
Bonded or unbonded — which suits your garage?
Bonded, from 30mm
- Existing slab is sound and dry
- Surface shot-blasted or ground for key
- Bonding primer applied before the pour
- Keeps floor height rise to a minimum
Unbonded, from 50mm
- Slab is cracked, contaminated or uneven
- Insulation wanted for a warmer workshop
- DPM and slip membrane laid first
- Screed floats independently of the old floor
How a garage pour runs
- 1
Site visit
We look at the existing slab, any falls, and the thresholds at the door and into the house, because finished height matters at both.
- 2
Preparation
Shot-blasting or grinding where the surface needs profile, then primer for bonded work or DPM and insulation for unbonded.
- 3
Pump day
The pump sits on the driveway. A typical single garage of 18–24m² is poured and levelled in well under a morning.
- 4
Protection
Covered for 24 hours, light foot traffic by day two.
- 5
Finishing
Laitance sanded off once dry, then coatings or floor finishes — typically 7–14 days on.
Things garage owners ask us to plan for
- EV chargers and car weight — a properly specified 40–50mm screed handles domestic vehicle loads
- Drainage falls — screed self-levels, so any fall is formed in the substrate first and screeded at constant thickness
- Cold weather — we won't pour below 5°C; winter jobs are heated or booked for a mild day
- Parking — allow at least 7 days before driving on, longer if a coating is going down
What a garage floor typically costs
| Area | Guide price supplied and laid |
|---|---|
| Under 50 m² (most single and double garages) | £28–£36 per m² |
| 50–150 m² (large workshops) | £22–£28 per m² |
A recent garage from our gallery
One of the jobs in our gallery is a garage floor refinished in Torquay — a worn slab brought back to a flat, clean surface with a fresh screed. Small garages sit in our under-50m² band because the pump and crew cost the same to bring whatever the size, but inside our 30-mile radius from Exeter there is no travel surcharge on top.
We use Cemfloor CT-C30-F6, a cement-based screed, for garages because it gives a robust, coating-ready surface. Wash-out is bagged and taken away, and the floor is left sheeted.
