Plastering and Gyproc: what does it cost per m² in Belgium in 2026?
Short answer: In Belgium in 2026, plastering costs about €11–16/m² in new builds (machine-sprayed) and €15–25/m² in renovation, while careful hand-applied plaster runs €18–45/m². A standard Gyproc partition costs €30–50/m² and a suspended ceiling €35–75/m², all excluding VAT, materials and fitting included. Allow 3 to 6 weeks for plaster to dry before painting.

Plastering or Gyproc: what is the difference?
Plastering is a wet layer of gypsum, lime or cement applied to an existing wall or ceiling, while Gyproc is a dry system of plasterboard screwed onto a metal frame. Plaster levels an existing surface; Gyproc builds a new wall or ceiling.
- Plaster: ideal for renovating brick or concrete walls, but it needs a long drying period before painting.
- Gyproc (plasterboard): ideal for a partition wall, wall lining or suspended ceiling that hides pipes and cables; only the joints need to dry.
- Suspended ceiling: boards fixed directly under the existing ceiling, or on a hung frame that leaves a void for spotlights and wiring.
Both techniques are often combined in an interior renovation: new Gyproc partitions and re-plastered existing walls.
Plastering and plaster finishes: price per m²
Plastering costs €11 to €16/m² excluding VAT in new builds (machine-sprayed) and €15 to €25/m² in renovation. Traditional hand-applied plaster with a careful finish sits more around €18 to €45/m². The gap comes from the finish level.
| Type of work | Range |
|---|---|
| Sprayed plaster, new build | €11–16/m² |
| Re-plastering in renovation | €15–25/m² |
| Traditional gypsum plaster, walls (careful finish) | €18–40/m² |
| Gypsum plaster, ceilings (careful finish) | €22–45/m² |
| Lime plaster | €25–55/m² |
| Decorative interior textured render | €30–70/m² |
| Smooth skim coat on plasterboard | €10–25/m² |
Sources differ because plastering covers very different finish levels: standard sprayed plaster ready for paint costs less than a perfectly flat hand-finished surface. Always state the finish level you expect when requesting a quote.
Gyproc partitions: price per m²
A single Gyproc partition costs €30 to €50/m² excluding VAT, materials and fitting included. With insulation, moisture-resistant boards or acoustic build-up, the price rises to €75/m², and higher for full sound-insulation systems.
| Type | Range |
|---|---|
| Single partition (one board per side) | €30–50/m² |
| Double-skin partition with insulation | €40–75/m² |
| Moisture-resistant partition (wet rooms) | €40–65/m² |
| Acoustic partition | €55–90/m², up to €110/m² for the most complete systems |
| Wall lining (bonded) | €25–40/m² |
Standard Gyproc is for dry rooms; bathrooms and utility rooms call for moisture-resistant boards, and walls between a bedroom and living room for acoustic boards with mineral wool. Prices differ between sources according to frame depth and insulation; the wide range above reflects that.
Suspended ceilings (moisture-resistant, acoustic): price per m²
A Gyproc suspended ceiling typically costs €35 to €75/m² excluding VAT: €35 to €60 when fixed directly, €55 to €75 on a hung frame, and up to €90 for high-end builds. Moisture-resistant and acoustic versions fall in the same zone.
| Type | Range |
|---|---|
| Fixed directly under the existing ceiling | €35–60/m² |
| Hung on a frame | €55–75/m² |
| With insulation | €45–70/m² |
| With recessed spotlights | €50–70/m² |
| Moisture-resistant (bathroom, kitchen) | €35–55/m² |
| Acoustic | €55–65/m² |
| High-end build | up to €90/m² |
| Removing an old suspended ceiling | €8–15/m² |
Direct fixing is cheaper but costs ceiling height and leaves no service void. A hung frame gives room for ducts and lighting. Finishing comes on top: about €15–30/m² for jointing and skimming and €25–35/m² for painting.
What drives the price
The price per m² depends mainly on the condition of the substrate, working height and surface area. Belgian comparison sites publish indicative ranges; only a quote after a site visit fixes the real price.
- Substrate condition: stripping old plaster (+€8 to 15/m²), damp-proofing treatment (+€5 to 12/m²), anti-crack mesh (+€3 to 8/m²), levelling (+€5 to 10/m²).
- Height: above 3 m scaffolding is often required (allow €200 to €400) and labour rises by 20 to 40%.
- Surface area: rates are degressive above 200 m² (up to 15–20% saving according to one source).
- Region: Brussels is typically 10 to 15% above average.
- Board and insulation: moisture-resistant, acoustic, mineral wool, PIR.
- Finish: jointing, sanding, smoothness before painting.
On site, a professional needs little time: at least one day for a small partition, four days or more for a complex project.
Drying times before painting
Generally allow 3 to 6 weeks before painting gypsum plaster, and a few days to a few weeks for Gyproc joints. In a new-build house, plaster can take much longer because of construction moisture.
- Gypsum plaster: Buildwise states it can be dry enough after roughly 3 to 4 weeks in favourable conditions; another Belgian source recommends 4 to 6 weeks.
- Gyproc and joints: depends on the jointing compound; some sources mention a few days at minimum, others cautiously 2 to 4 weeks.
- New-build house: several weeks to months, depending on building moisture.
Thickness, ventilation, temperature and humidity all change these times. Forcing the drying with intense heating can crack the plaster. Have a professional assess the moisture of the surface before painting: painting too early traps moisture and damages the finish. For the cost of painting itself, see our painter cost per m² guide.
VAT: 6% or 21% on this work
The 6% rate applies to renovating a private home older than 10 years when the work is invoiced by a registered contractor; otherwise 21% applies. In new construction, plastering is in principle invoiced at 21%.
- 6%: home older than 10 years, private use, work invoiced to the homeowner by a registered contractor.
- 21%: new construction as a rule, and materials you buy yourself.
- Demolition and rebuild: since 1 July 2025 a permanent 6% regime exists under conditions, with a prior declaration through MyMinfin.

Comparing quotes without surprises
Ask for at least three detailed written quotes based on the same specification. A price per m² only means something if you know what it includes.
- Fix the finish level: ready to paint, smooth, basic joints or careful finish.
- Check ex-VAT or incl. VAT and the rate applied.
- List the extras: substrate preparation, scaffolding, rubble removal, floor protection.
- Specify the boards: standard, moisture-resistant or acoustic, frame depth, insulation type.
- Ask for the schedule and the drying time allowed before painting.
