# What Is Gib Stopping? Everything Christchurch Homeowners Need to Know

If you're building a new home, doing a renovation, or noticed rough or cracked walls in your Christchurch home, you've probably heard the term "gib stopping." It's one of those trades that's invisible when done well — and glaringly obvious when it isn't.
Here's a plain-English explanation of what gib stopping is, when you need it, and what to look for in a good gib stopper.

## What Is Gib Stopping?
Gib stopping (also called plastering, skimming, or GIB finishing) is the process of applying plaster compounds to the joints, screw holes, and surface of plasterboard (known as GIB board in New Zealand, after the dominant brand) to create a smooth, paint-ready finish.
When GIB board goes up, you can see every:
- Joint between sheets
- Screw hole from fixing
- Corner bead at edges and internal corners
- Surface imperfection or dent in the board
Gib stopping fills and feathers all of these out so the wall is perfectly flat. Without it, every imperfection shows through paint — especially under raking light or in rooms with large windows.

## Gib Stopping vs Plastering — What's the Difference?
In everyday New Zealand conversation, the terms are used interchangeably, but technically:
- Gib stopping refers specifically to finishing GIB (plasterboard) — the new build standard
- Plastering is a broader term that covers applying solid plaster to walls, repairing existing plaster, re-coating old surfaces, and traditional hard-coat plaster systems
At 2G Interiors, we do both. We work on new builds where everything is GIB board, renovations where we're repairing existing plaster, and everything in between.

## When Do You Need Gib Stopping?
### New Builds
Every new home or addition built with GIB board needs to be stopped before it can be painted. This is typically done in three stages:
1. Stopping coat 1 (base coat) — fills joints and screw holes, sets the foundation
2. Stopping coat 2 (wet coat) — wider, flatter application that starts to blend
3. Final coat (skim/finish) — thin, tight finishing layer before sanding
### Renovations and Repairs
- Removing walls and patching where they joined
- Fixing cracks (common in Christchurch homes post-earthquake)
- Repairing holes from fixtures, pipes, or accidents
- Replacing sections of damaged or damp-affected GIB board
### Before Repaints
Sometimes a wall looks fine until you change the paint colour or switch from flat to a sheen finish — then every bump and ridge becomes visible. Pre-paint surface preparation, including stopping and sanding, is often needed on older homes.

## Why Does Quality Gib Stopping Matter So Much?
Paint magnifies imperfections — it doesn't hide them. The quality of a finished paint job is directly dependent on the quality of the surface underneath.
A cheap or rushed stopping job will leave:
- Visible joins under raking light
- Ridges or "crows feet" where feathering wasn't done properly
- Screw pops appearing within months as the building settles
- Flashing — areas where the wall reflects light differently due to uneven absorption
Fixing bad stopping after painting means sanding back, re-stopping, repriming, and repainting. It's far cheaper to do it right the first time.
At 2G Interiors, our gib stoppers are fully trade-qualified and we take surface preparation seriously. It's not glamorous work, but it's the foundation everything else sits on.

## What Does Gib Stopping Cost in Christchurch?
Gib stopping is usually priced per square metre of GIB board, or as part of a full paint-and-plaster package.
| Job Type | Typical Range |
|----------|--------------|
| New build stopping (per m²) | $15 – $30/m² |
| Patch repair (per hole/area) | $150 – $600 |
| Full room re-plaster/skim | $600 – $2,000+ |
| New build full house (stop + paint) | $8,000 – $18,000+ |
Pricing varies based on the level of finish specified (Level 3, 4, or 5 — more on that below), the amount of board, and access.

## Gib Finishing Levels — What Level Do You Need?
The NZ Gib installation system uses finish levels:
- Level 3 — basic finish, suitable for textured coatings or areas not in primary view
- Level 4 — standard residential finish, suitable for flat or low-sheen paints in normal lighting
- Level 5 — premium skim coat finish, required where gloss or semi-gloss paints are used, or in rooms with strong raking light (kitchens, bathrooms, hallways with sidelighting)
We'll always recommend the appropriate level for your space and paint specification. High-end homes and architecturally designed properties often specify Level 5 throughout — we deliver that standard routinely.
---
## How Long Does Gib Stopping Take?
Each coat needs to fully dry before the next is applied. In a Christchurch summer, this can be 12–24 hours per coat. In winter or damp conditions, it can be 48 hours or more.
For a typical new build room, allow 3–7 working days from first coat to paint-ready. For a whole-house new build, gib stopping typically takes 1–3 weeks depending on size and season.

## Frequently Asked Questions About Gib Stopping
How do I know if my walls need stopping before painting?
Run your hand along the wall in different lighting conditions. If you feel ridges at joins, or see reflections in raking light, you likely need some remedial stopping work before painting.
Can I gib stop myself?
You can do basic hole patching with DIY products from Mitre 10. However, professional-quality stopping — especially feathering wide joints to be invisible — takes years of practice and specialist tools. Most DIY stopping is visible through paint.
Do you work with builders on new builds?
Yes. We regularly work alongside builders, project managers, and architects on new builds and large renovations across Christchurch. We're comfortable working to builder timelines and coordinate directly with site supervisors.
What's the difference between stopping and skimming?
Skimming refers to a final thin coat applied over an entire wall or ceiling surface to create a perfectly uniform base. It's part of a Level 5 finish. Stopping is the broader process of which skimming is one stage.
Do you do earthquake-related plaster repairs?
Yes. Many Christchurch homes still have cracking or movement from the 2010–2011 earthquakes. We assess, repair, and refinish affected areas to match the existing surface.
