Plastering, GIB Stopping & Skim Coating in Hamilton
Level 5 Plasterers & GIB Stoppers for Ultra-Smooth, Paint-Ready Walls & Ceilings
As trusted Hamilton plasterers and GIB® stoppers, Tomar Contracting delivers premium plastering, GIB® stopping and Level 5 skim coating across Hamilton and the wider Waikato — from GIB fixing and stopping on new builds to skim coating walls and ceilings in renovations. A Level 5 finish is the highest standard defined under the AS/NZS 2589 plasterboard finishing standard — a full skim coat over the entire surface that leaves walls and ceilings dead-flat and free of visible joints, fastener marks or texture. It’s the finish that makes gloss and semi-gloss paint look immaculate, and it’s the perfect foundation for our interior painting and residential painting work.
The Levels of Plaster Finish — and Why Level 5 Wins
GIB® stopping is graded from Level 0 to Level 5 under AS/NZS 2589. The higher the level, the smoother and more uniform the surface. Level 5 is the premium, skim-coated finish specified where lighting and paint sheen leave nowhere to hide.
No finishing or a single rough coat. Temporary walls only.
Basic stopping. Suitable behind tiles, in garages and utility spaces.
Two-coat stopping for heavy textures or wallpaper.
The common paint-ready finish for most homes and flat/matte paint.
Full skim coat over the entire surface. Flawless under gloss paint & raking light.

What Exactly Is a Level 5 Skim Coat?
A Level 5 finish takes a standard Level 4 stopped wall one step further: a thin, continuous skim coat of plaster is trowelled across the entire surface, not just the joints and screw heads. That extra coat evens out the difference in suction and texture between the paper face of the GIB® board and the stopping compound, so the wall reads as one seamless plane.
Level 5 is worth it when you have:
- Gloss or semi-gloss paint: higher sheen reflects and magnifies every imperfection.
- Critical or raking light: large windows, skylights and LED downlights skim across walls and expose flaws.
- Feature walls & dark colours: deep tones and accent walls show texture that pale matte finishes hide.
- High-end & architectural homes: premium interiors, showrooms and commercial lobbies.
Gloss or semi-gloss paint: higher sheen reflects and magnifies every imperfection.
GIB® Stopping Done Properly
A flawless Level 5 result is built on solid GIB® stopping. Our plasterers tape and stop every joint, internal and external corner, and fastener with multiple coats of compound — allowing correct drying time between each — before feathering everything out wide and sanding it dead-flat.
Rushed stopping, under-coating and poor sanding are the reasons paint jobs disappoint. We treat the substrate as the most important layer of the whole project, because no amount of premium paint can hide a wall that wasn’t prepared to standard.

Our Level 5 Process
A clear, methodical process is how we guarantee a wall that stays flawless once the light hits it and the paint goes on.
How we work:
- Assess & protect: we check the substrate, mask up and set up dust control.
- Tape & stop: joints, corners and fasteners are taped and stopped.
- Build coats: multiple stopping coats, each dried and feathered wide.
- Full skim coat: a continuous Level 5 skim across the whole surface.
- Fine sand & light-check: sanded flat and inspected under raking light.
- Paint-ready handover: primed and ready for a flawless paint finish.
Skim Coating Over Textured Walls & Ceilings for a Modern Smooth Finish
Bumpy, dated textured walls and popcorn ceilings instantly age a home. A skim coat is the fastest way to bring them into the present — we skim straight over the texture to create a fresh, smooth, contemporary surface without the mess and cost of a full re-line.
It’s a high-impact upgrade before selling, renovating or repainting, and it pairs perfectly with a fresh coat of paint for a complete transformation.
What Drives the Cost of Plastering & Skim Coating?
Every project is different, so we quote on the wall — not by guesswork. The single biggest lever on price is the finish level you need: a Level 5 skim coat takes more time, skill and material than a standard Level 4 stop. Other factors include:
- Area & scope: whole-house work usually prices better per m² than a single room.
- New work vs repair: patching and making-good differs from stopping fresh board.
- Ceiling height & access: stairwells and high ceilings need staging.
- Occupied vs empty: extra protection and dust control on lived-in homes.

Plastering & Skim Coating Frequently Asked Questions
A Level 4 finish stops the joints, corners and fasteners and is the standard paint-ready finish for most homes using flat or matte paint. A Level 5 finish adds a full skim coat across the entire surface, creating a dead-flat, uniform wall with no visible joints or texture — essential for gloss/semi-gloss paints and critical lighting.
GIB® stopping is the process of taping and filling the joints and fastener heads of plasterboard with compound, then sanding smooth. Skim coating goes further, applying a thin plaster coat over the whole surface. Together they produce the seamless base your paint finish sits on.
Yes — skim coating over textured or painted surfaces is a popular way to modernise walls and ceilings without a full re-line. We skim straight over the old texture to leave a smooth, paint-ready finish. Note that some textured ceilings in older homes can contain asbestos, so if your home pre-dates the 2000s we recommend testing before any removal work.
It depends on the size and finish level. A typical three-bedroom home takes roughly 5–10 working days for full GIB® stopping including drying time between coats, with a Level 5 skim adding time for the extra coat and sanding. We’ll give you a clear schedule with your quote.
Cost depends mostly on the finish level, plus the area, whether it’s new work or repair, ceiling height/access and whether the home is occupied. Use our instant estimate calculator for a fast ballpark, then we confirm a fixed written quote after a site visit.
Absolutely. We’re painters as well as plasterers, so we can take your project from bare board through to a flawless finished coat — one team, one point of accountability. See our painting services.
We use professional-grade jointing compounds matched to each coat — a stronger setting-type compound for taping and building coats, and a smooth air-drying topping compound for the final Level 5 skim. Using the right compound for each stage is what delivers a hard-wearing, glass-smooth finish.
