OUR APPROACH

Why Choose Our Plastering Services

Paint doesn't hide bad walls — it advertises them. Wellington's housing stock makes this worse than most places: century-old villas in Newtown and Berhampore with cracked lath-and-plaster, 1970s Gib that's popped its nails after decades of small quakes, and new builds where the stopper was rushed and every joint shows up the first sunny afternoon. Low winter sun raking across a wall is brutal at exposing joints, screw pops, and patch marks.

Most of the plastering work we do in Wellington is fixing exactly that: settlement cracks above door frames, water-damaged ceilings, and joints that were stopped in two coats when they needed three. We build coats up properly, sand between every layer, and check the finished surface under raking light — the same light that will find the flaws once the room is painted.

Our Commitment to Quality

As Registered Master Painters and Resene Eco Decorators, we stand behind every plastering job with our 5-Year Workmanship Guarantee. Our team uses premium stopping compounds and quality tools to ensure a durable, long-lasting finish. We set realistic timelines and always honour our commitments. If any issues arise after completion that are caused by our workmanship, we provide a free touch-up service. We work across Wellington, Lower Hutt, Upper Hutt, Porirua, and the Kapiti Coast.

OUR PROCESS

Our Plastering & GIB Stopping Process

We follow a systematic process to deliver smooth, paint-ready surfaces every time:

  1. Assessment: We inspect all wall and ceiling surfaces to identify cracks, holes, uneven joints, damaged GIB, or areas that need repair before stopping can begin.
  2. GIB Installation (if required): For renovations or new rooms, we install new GIB board to manufacturer specifications, with correct fixing and spacing.
  3. First Coat Stopping: All GIB joints, screw holes, and corner beads receive a first coat of quality stopping compound. This base layer fills the major gaps and establishes the foundation.
  4. Sanding: Once dry, surfaces are sanded smooth to remove ridges and high spots. We sand between every coat — skip it and the joints telegraph through the paint.
  5. Second Coat Stopping: A wider second coat feathers the joints outward so they disappear into the surrounding board. Additional coats are applied to internal and external corners.
  6. Final Sand & Inspection: A light final sand ensures all surfaces are perfectly smooth. We inspect under strong lighting to catch any imperfections before priming.
  7. Priming: A quality sealer or primer is applied to create a uniform surface for the topcoat paint to adhere to evenly.

Types of Plastering Work

Day to day, our plastering work across Wellington, the Hutt Valley, and Porirua looks like this:

  • New GIB installation & stopping: Complete wall and ceiling lining for new builds, extensions, and renovations
  • GIB stopping for renovations: Matching new work to existing wall textures and finishes
  • Crack & hole repairs: Fixing settlement cracks, accidental damage, and wear over time
  • Skim coating: Applying a thin plaster layer over existing surfaces for a fresh, smooth finish
  • Textured finishes: Creating specific wall textures to match existing decor or achieve a desired look
  • Water damage repairs: Replacing and stopping GIB affected by leaks or moisture

Finish Levels Explained

Not all plastering jobs require the same level of finish. The right level depends on the final paint type and the room's use:

  • Level 4 (Standard): Suitable for most residential rooms where flat or low-sheen paint will be used. Joints are stopped, sanded, and finished to a smooth standard.
  • Level 5 (Premium): Required for areas with gloss or semi-gloss paint, or where strong lighting may highlight surface imperfections. Includes a full skim coat over the entire surface for a flawless result.

We'll tell you which level your job actually needs — paying for Level 5 in a flat-paint bedroom is wasted money, but skipping it under a gloss hallway ceiling is a mistake you'll see every single day.

TIPS

Things to Keep in Mind

Plastering & GIB Stopping Considerations

Surface Inspection

Identify issues first

Check for cracks, holes, and uneven surfaces. All imperfections should be identified before plastering or stopping begins.

Proper Preparation

Clean surfaces first

Dust, dirt, grease, or loose material must be removed before stopping — compound won't bond to a dirty surface.

Joint Treatment

Prevent future cracking

GIB stopping requires correct taping and joint compound application to prevent future cracking or shrinkage.

Multiple Coats and Drying Time

Patience for quality

Most plastering and stopping require multiple coats, and each coat needs proper drying time — rushing it is what causes shrink-back and visible joints.

Sanding and Finishing

Achieve uniformity

Once dry, surfaces should be sanded carefully for a uniform finish ready for painting.

Moisture Control

Dry surfaces only

Ensure walls and ceilings are dry before plastering or stopping. Excess moisture can cause adhesion problems and cracking.

Quality of Materials

Right products matter

Use the right plaster or stopping compound for the surface type and expected wear — the wrong product fails early.

Timing Before Painting

Allow full cure

Fresh plaster and stopping must be fully cured before painting. Rushing this step can lead to paint adhesion failure and visible defects.

FAQ

Common Questions

Find answers to frequently asked questions about our plastering services.

What is GIB stopping and why is it important?

Filling joints, screw holes, and imperfections in plasterboard to create a smooth, even surface. Without it, every joint and screw line shows through the paint.

How long does plastering or GIB stopping take?

Depends on area size and number of joints. Typically 2 to 3 coats with drying time between each.

Can you paint immediately after GIB stopping?

No. Surface must be fully dry and sanded smooth. Moisture or uneven stopping causes cracks or paint defects.

How much does GIB stopping cost in Wellington?

Standard room typically $500 to $1,500 depending on area size and finish level required.

What GIB stopping finish level do I need?

Level 4 is standard for most homes. Level 5 recommended for areas with critical lighting or gloss paint finishes.

Do you handle both new builds and renovation plastering?

Yes, new construction and renovations or repairs — we match new work to existing wall textures so you can't tell where the patch ends.

Will cracks or imperfections reappear after stopping?

Minor settling cracks can occur in new builds, but multiple coats and proper sanding minimise this. Future minor cracks are easy to repair before repainting.

What does your plastering service include?

New GIB installation, GIB stopping and finishing, wall repairs and patching, crack and hole repairs, skim coating, and textured finishes.
