Priced on Net Area, Not Gross

Plastering is priced by area, and area is where a lot of estimates go wrong.

Gross room perimeter times height is not the same as net plastered area once you deduct windows and doors, then add raked sections, skillion edges and bulkheads. All of that has to be resolved before a labour rate goes anywhere near it.

We produce plastering estimates for Perth residential and commercial projects. Internal plaster areas by room, external render areas by elevation, bead schedules, cornice quantities and finishing labour, all measured from your plans.

What We Cover in a Plastering Estimate

Element	How We Measure	Notes
Internal plaster walls	m2 by room, height x perimeter less openings	Skillion and raked ceilings measured separately
Internal plaster ceilings	m2 by room area	Coffered and suspended ceilings noted
External render	m2 by elevation, height x width less openings	Render type and coat specification noted
Beads	LM for stop beads, movement beads and corner beads	By location and finish type
Cornices	LM for internal and external cornices by profile size	Curved cornices priced as a separate rate
Bulkheads and columns	m2 by configuration	Curved or angled surfaces at a separate rate
Wet areas for tiled prep	m2 for waterproofing prep coat or CSR Wet Area Board	Separate material and labour rate
Finishing coats	m2 by finish specification, set or off-the-float	Texture finish types priced separately

Standard plastering estimate elements for Perth residential construction. Commercial jobs add shaft walls, fire-rated assemblies and specialist acoustic systems.

What Is Included in a Plastering Estimate?

A Perth plastering estimate covers internal plaster walls and ceilings, external render on masonry or fibre cement, stop beads and corner beads by linear metre, cornice quantities, and labour rates for each element. Finishing coat specification, whether set coat, texture or off-the-float, affects the rate and must be specified in the estimate.

Internal and External Are Different Jobs

Internal plaster on double-brick is typically a sand-and-cement scratch coat with a white set finish. External render on the same masonry can be anything from a plain sand-and-cement coat to a proprietary acrylic texture system.

Both need accurate areas. The material and labour behind them are nowhere near the same number.

Render Systems From Sand-Cement To Acrylic

Traditional sand-and-cement render in one or two coats
Float and texture finish, whether trowel texture, sponge float or scraped
Acrylic texture render systems (Rockcote, Texture Plus, Dulux AcraTex)
Fibre cement sheet with joints and fixings before render application
EPS (expanded polystyrene) cladding systems for thermal performance
Masonry paint system where render is not specified

The Coat You Cannot See Is The One That Costs

A rendered wall is rarely one pass. There is a scratch coat, a float coat and a finish coat, and each one is its own trip around the building with its own labour.

Estimates go wrong when a single square metre rate gets applied to a wall that the specification says needs three coats and a texture finish over the top.

We read the finishes schedule first and rate each elevation to the system it is actually getting. If the spec is not settled yet we price the likely option and flag the line so it is easy to swap.

Perth Plastering Rates vs National Averages

Perth plastering rates have tracked higher than the eastern states for most of the last decade.

An estimate built on Sydney or Melbourne labour will under-price a Perth job before you have quoted a single square metre. We use current local market rates in every estimate.

Common Questions

Straight answers on how we price plastering and render estimating in Perth. If yours is not here, send your plans and just ask.

External render is measured by elevation, taking the wall height from finished floor level to eave or parapet, multiplied by the width of each elevation, less window and door openings. Where recesses, blade walls or curved surfaces exist, those are measured and priced at a separate rate.

Yes. Cornice is measured in linear metres by room and priced by profile size. Standard 55mm and 75mm cornice is common in Perth residential; larger colonial profiles and curved cornice are priced at a higher rate due to the additional skill and time involved.

Yes. Renovation plastering is more variable than new construction. Patching, matching existing texture and finishing around existing fittings all affect the labour rate. Send us the scope and we will provide an estimate with clear notes on any areas of variability.

Plasterboard (Gyprock, Knauf) installation is a related but separate trade. We estimate plasterboard fixing and jointing as part of a ceiling or internal wall scope. Send us the drawings and we will include it.
