Internal Linings Sunshine Coast | Level 3 & Level 5 Plastering | Clark Build Group

Level 3 is standard. Level 5 disappears.

Premium plasterboard installation in genuine CSR Gyprock, fixed and finished properly by a Sunshine Coast specialist who'll always tell you plainly which finish level your room actually needs.

The Right Board, Fixed Properly

From standard residential to architectural curves.

Premium plasterboard installation, from standard residential through to fire-rated, acoustic, and architectural curved applications. We fix and finish every board properly, because a lining job lives or dies on the prep work nobody sees once the paint goes on.

Every job is completed in genuine CSR Gyprock, the Australian standard for plasterboard and jointing systems, and we'll always specify the board that actually suits your application, not the cheapest one on the truck.

The Material

CSR Gyprock. The board this country builds on.

CSR Gyprock is the Australian standard for plasterboard, jointing compound, and finishing systems, and it's the only brand we install. Below, the standard we're actually building to, explained properly.

The Standard

Level 3. Level 5. Only one disappears.

The Australian Standard

Level 3 Finish

The board is hung, then base coat is used to bed and tape every joint and screw hole. A top coat over the base creates a smooth, easily sanded blend between the plasterboard face and the plaster joints, sealed with a texture-roller primer coat before paint. Done properly, it's a solid, reliable finish, and what the vast majority of homes are built to.

  1. Hang plasterboard
  2. Base coat, bed and tape joints and screws
  3. Top coat to blend joint into board
  4. Texture-roller primer coat, ready for paint
The Premium Standard

Level 5 Finish

Everything in a Level 3 finish, completed first. Then a pre-paint textured roller pass of primer over the whole surface, followed by a full skim coat of plaster compound spread across the entire wall or ceiling by trowel or roller and worked back to blend every imperfection and fill every hollow. Once cured, the whole surface is sanded to a smooth, blemish-free finish ready for paint.

  1. Complete Level 3 finish first
  2. Pre-paint textured roller coat
  3. Full skim coat across entire surface
  4. Sand back to a smooth, joint-free finish
Board Types

The right board for the right room.

Standard

Everyday residential walls and ceilings where a Level 3 or 5 finish covers the requirement.

Moisture Resistant

Bathrooms, laundries, and any space with sustained humidity exposure.

Fire Rated

Party walls, garages, and anywhere a fire rating is a compliance requirement, not a preference.

Acoustic

Media rooms, home offices, and shared walls where sound transfer needs to be minimised.

Fibre Cement

Villaboard and similar products for wet areas and exterior-adjacent applications.

Flexible

Curved walls, arches, and architectural details that standard sheet board can't achieve.

Common Questions

Straight answers. No runaround.

What's the difference between Level 3 and Level 5?

Level 3 is the Australian standard, taped, base coated, top coated and sealed with a primer roller. Level 5 goes further, adding a full skim coat across the entire surface after a pre-paint primer pass, then sanding it smooth, so there's nowhere for shadows or joints to show even under harsh light.

Do I need Level 5, or is Level 3 enough?

For most rooms with standard lighting, a properly executed Level 3 finish looks great. Level 5 earns its cost in rooms with harsh natural light, large glazing, low-sheen paint, or raking feature lighting, since that's exactly the light that reveals every joint in a Level 3 finish.

Why CSR Gyprock specifically?

It's the Australian standard for a reason: consistent board quality and a jointing system that's proven across every climate this country has, including the humidity here on the coast.
