Starting an Exterior Repaint on a Central Coast House

Exterior painting covers every coated surface outside a house: the cladding that covers the walls, the eaves under the roof overhang, the fascia boards along the roof edge, gutters, handrails, decks and fences. On the Central Coast a single street can hold a post-war fibro cottage, a holiday house clad in timber weatherboards, a brick home coated in cement render and a new build clad in fibre cement. Each of those surfaces needs its own paint system, which is the full set of coats a maker specifies for it, from the first coat to the finishing coats. Primers are first coats that grip bare material, sealers even out how much paint a porous surface soaks up, undercoats build an even base for the colour, and topcoats are the finishing coats you see. Good exterior quotes name the system for each surface, so you can see exactly what will go onto the walls, the timber and the metal.

For hiring steps, licence checks and contract rules, read our guide to hiring a painter on the Central Coast, and the full price tables are in our guide to Central Coast painting costs. Inside work, including lead paint testing and mould on internal walls, is dealt with in our guide to interior painting on the Central Coast. Outside work brings its own risks, including salt on steel near the sea, asbestos in older wall sheeting and falls from second-storey eaves. Brand names below show the kinds of products a quote may list, and each one is a product its maker currently sells. You do not need to pick products yourself, but knowing what each coat does makes written quotes much easier to compare. If a painter can describe the system for each surface in plain words, you can check the finished job against that description.

Exterior Repaint Estimates for 2027 by Surface and Height

For 2027, a full exterior repaint of a single-storey, three-bedroom Central Coast house is estimated at $5,000 to $11,000, and a two-storey home at $8,000 to $17,000. Those figures assume two finishing coats over sound existing paint with standard preparation, meaning washing, scraping loose flakes, filling cracks and priming any bare patches. Scaffolding for a two-storey home is estimated at a further $1,500 to $4,000, depending on the length of the walls and how steep the block is. Measured by wall area, two coats with standard preparation is estimated at $28 to $45 per square metre. Painters who charge by the hour are estimated at $55 to $85 an hour, or $440 to $680 a day for each painter. State-wide breakdowns sit in the NSW guides to house painting costs and painting cost per square metre.

The type of surface affects the price as well as the size of the house. Fibro needs gentle cleaning and a careful first coat, weatherboards need nail heads punched below the surface, holes filled and bare spots primed, and texture-coated walls take more paint per square metre than smooth render. Metal work such as gutters, downpipes and balustrades is slow to prepare by hand, so it can be priced as its own line. When every surface is lumped into one figure, you cannot see what each part costs.

How Painters Measure and Stage an Exterior Job

Exterior quotes are built from measurements of each elevation, which is one face of the house seen from the front, the back or either side. Wall area is measured in square metres, eaves, fascias and gutters are counted in lineal metres, meaning their length along the house, and windows, doors and downpipes are priced as separate items. Full repaints can be priced as one fixed sum, while hourly or daily rates suit repairs, touch-ups and jobs where hidden rot cannot be measured until boards come off. For work charged on time and materials, meaning hours worked plus the cost of materials, a quote should state the hours expected and how any extra hours will be approved before they are worked. Breaking the price down by elevation also lets you drop or delay one side of the house if the budget runs short.

Large exterior jobs can be split into stages, with preparation of every surface finished before any colour goes on. Staging the work this way lets you inspect filled cracks, primed timber and treated rust while they are still visible. Once the topcoats cover them, it is hard to tell whether a nail hole was filled or a rust spot was only painted over. Progress payments can be tied to the same finished stages, such as preparation complete, primers applied and final coats done. Before agreeing to progress payments, check the NSW deposit limits and written contract rules for home building work in our guide to hiring a painter on the Central Coast. Photos of each elevation taken at the end of preparation become useful evidence if the paint later fails early.

Rain can halt exterior work for days, so the contract should say how a stoppage changes the finishing date. A weather delay should not raise a fixed price, although a long stoppage can mean the scaffold stays on hire for longer than planned. Check whether the quote covers extra scaffold weeks or passes that cost on to you. Agreeing the order of elevations at the start helps you plan around blocked windows, doors and paths on each side.

AS 4312 Corrosivity Categories and Painted Steel

Salt in the air speeds up rust on steel, and the rate depends on how much salt reaches the surface. Australian Standard AS 4312, Atmospheric corrosivity zones in Australia, sold through Standards Australia, sorts locations into categories from C1, the mildest, through C5 to CX, the most severe. Simpson Strong-Tie, which makes steel building connectors, publishes a technical guide that describes C5 as roughly the first 200 metres from rough seas and surf beaches. The same guide places C4 at about 200 metres to 1 kilometre inland from surf, and also on calm sea shores. Dulux Protective Coatings places CX near surf beach shorelines, and notes that winds, topography and vegetation change how far each category reaches inland. A house facing the surf at Wamberal and one on the plateau at Kariong can fall into different categories, so a quote for painting steel should allow for the distance from the surf.

Ordinary house paint is not designed to be the main protection for exposed steel. The scope of AS/NZS 2311, Guide to the painting of buildings, states that it does not cover long-term protection of exposed iron or steel, and points to the AS/NZS 2312 series instead. AS/NZS 2312.1 guides the protection of steel with paint coatings, and it rates each system by durability, the time until the first major maintenance such as recoating or patch repairs. The Dulux Protective Coatings guide stresses that a durability range is a planning aid for maintenance, not a warranty. For a steel balustrade, gate frame or carport post near the beach, ask whether the system comes from a protective coatings range or from ordinary house paint.

House paint makers also set their own rules for metal close to the sea. Dulux calls for one coat of its Precision All Metal Primer on galvanised steel and Zincalume within 1 kilometre of the sea before Weathershield topcoats, and it sets out separate preparation for metal further inland. Galvanised steel carries a zinc coating to slow rust, while Zincalume is BlueScope's steel with an aluminium and zinc coating. A painter who skips a primer the maker requires can leave you without the maker's guarantee if the paint later fails.

Painting Fibro Without Breaking the Surface

Fibro is the everyday name for asbestos cement sheeting, a building board of cement reinforced with asbestos fibres that was used for walls, eaves and fences. The NSW Government warns that asbestos is a particular concern in buildings constructed before 1990, and asbestos has been banned in Australia since 2003. Whatever the suburb, an older Central Coast house could have fibro in its walls, eaves linings or fences, so the build date is the first thing to check. Painting does not remove the hazard, but the NSW Government's asbestos information site says sheeting such as fibro can be sealed with good quality paint. That holds only when nothing breaks the cement surface during cleaning, preparation or painting.

The code of practice How to manage and control asbestos in the workplace, published in NSW by SafeWork NSW, says asbestos must never be water blasted or dry sanded before painting, coating or sealing. Under the same code, high-pressure water spray and compressed air must not be used on asbestos at all. Scraping, scrubbing, drilling and cutting also appear on the NSW asbestos site's list of activities to avoid. For cleaning, the code describes using an asbestos vacuum cleaner, one fitted with a high-efficiency filter, to remove loose dust before the sealant goes on. It prefers a low-pressure airless sprayer, which pumps paint through a fine tip without compressed air, because rollers and brushes can abrade unsealed sheeting and release fibres. Any quote that lists pressure washing or sanding for a fibro house is a clear reason to choose another painter.

If you are not sure whether a wall, eave or fence is fibro, have a sample tested before any preparation starts. Our NSW guide to asbestos testing and inspection shows how samples are taken and what testing costs. Sealing only suits sheeting in sound condition, so cracked, crumbling or badly weathered sheets need assessment before any paint goes on. Damaged sheeting may need specialist asbestos encapsulation or asbestos removal by a licensed contractor. Painters who work on fibro should be able to describe the controls they will use, from cleaning to the first coat.

First Coats for Timber, Masonry, Fibro and Metal

Every exterior surface has a different reason for needing a first coat. Bare timber needs a primer that soaks in and grips the fibres, new render needs a sealer that copes with the alkali in fresh cement, and bare steel needs a primer that slows rust. Over sound, well-bonded old paint, a maker may allow the topcoat to go straight on after cleaning. The maker's product data sheet, a short technical document for each paint, states which first coat applies to each surface.

Dulux, for example, lists different first coats under its Weathershield topcoats depending on the surface. Hardwood takes one coat of 1Step Prep Water Based, while new timber rich in tannin needs 1Step Prep Oil Based or the maker's stain and odour blocker. Tannin is the natural brown colouring in some timbers that can bleed through light-coloured paint. Unpainted masonry must cure for 28 days before painting, and efflorescence, the white salt crust that forms on masonry, should be treated with an etch and clean product or weak acetic acid, as in vinegar. Zinsser, a brand of Rust-Oleum, makes primers including Cover Stain, an oil-based primer that blocks stains. Wattyl makes the Killrust range of metal primers and enamels, which includes an etch primer, a first coat made to grip smooth metal such as galvanised steel.

Timber Boards, Tannin Bleed and Bare End Grain

Timber weatherboards, long horizontal boards that overlap down the wall, may clad an older cottage or holiday house, and some newer homes use them as feature cladding. Preparation starts with a close look at every board for soft spots, splits, rusted nail heads and joints where old gap filler has shrunk away. Soft timber should be cut out and replaced before any paint goes on, and our guide to weatherboard and cladding repairs describes that carpentry work. Rusted nail heads are punched below the surface, primed on the bare spot and filled, since rust left in place can stain through the new topcoat. For prices on repainting boards in different conditions, see the state-wide weatherboard painting cost guide.

End grain, the cut end of a board where the wood fibres are exposed, soaks up water much faster than the face of the board. The lower edges and joins of boards catch water running down the wall, so they need priming and a full topcoat, not a quick pass of the roller. Weathered grey timber has a loose surface layer that should be sanded back to firm wood, since paint can lift away with it. Feast Watson makes Woodprep for preparing timber, along with a Timber Primer for bare wood. For weathered timber rich in tannin, Dulux lists three coats of Weathershield. Sanding old paint on an older house raises the separate risk of lead, and our guide to lead paint testing and removal lists the testing options.

Gaps between boards, trims and window frames are filled with a flexible exterior sealant before the topcoats go on. Sika makes facade sealants and joint products for exterior building work. Rigid fillers belong in nail holes and dents, while moving joints, such as the corner where boards meet a window frame, need a sealant that stretches. Paintable sealants should be left for the curing time their maker states before any paint goes over them.

Fibre Cement Cladding and Texture-Coated Walls on Newer Homes

Some newer homes are clad in modern fibre cement, a board made from cement and cellulose fibres without asbestos, in weatherboard or panel styles. James Hardie makes cladding including Linea Weatherboard, which it supplies pre-primed, and Stria Cladding, which it supplies pre-primed and ready to paint. A factory primer is a base for paint, so these boards still need topcoats applied to the maker's instructions. Cut edges and nail holes made during building should have been sealed, and a painter repainting an older fibre cement house checks those edges for swelling or flaking. Because fibre cement can look like fibro, the age of the house and any building records help a painter decide which rules apply. If there is any doubt, the sheeting should be treated as fibro until a test shows otherwise.

Some newer homes also carry texture coatings, thick acrylic finishes applied over lightweight panels or render to give a sand or trowelled look. Dulux makes the AcraTex range of renders and texture coatings, and Rockcote makes coloured renders, quick renders and textured finishes. Repainting a texture coating means following the original system's maker, because some coatings sit within panel systems that set their own paint rules. Texture finishes hold more paint per square metre than smooth walls, which raises the material cost of each coat. If your render is cracked or newly applied, see render painting costs and render and texture coating for crack repairs and first coats.

Gutters, Fascias, Handrails and Prepainted Steel

Metal around the outside of a house includes gutters, downpipes, fascia covers, balustrades, handrails and gates. On newer homes some of it may be Colorbond, BlueScope's prepainted steel, while older homes may have bare galvanised steel or steel painted many times over. Each type needs a different approach to cleaning and priming before any colour goes on. Painting the roof sheeting is a separate job, and you can compare its prices in our guides to roof painting costs and Central Coast roofing costs.

BlueScope's technical bulletin on overpainting says Colorbond steel can be overpainted successfully, but doing so voids BlueScope's warranties. For Colorbond less than about a year old, it describes washing with detergent and water, then lightly scouring with kitchen scourer pads, not steel wool, to remove the gloss. Older Colorbond that has weathered evenly needs washing, rinsing and drying before it is painted. On Zincalume and zinc-coated steel showing rust, the bulletin says to remove only the corrosion with a stiff nylon brush and apply a thin zinc-rich etch primer. It names water-based acrylic as generally the most suitable paint type, and says a system with better corrosion resistance, such as one with a zinc-rich primer, may be needed in corrosive salt marine locations. BlueScope also advises against mixing paints from different suppliers in the one system.

Steel that has rusted needs more than a fresh coat over the top. Loose rust and flaking paint should be taken back to firm metal, and Dulux lists two coats of its All Metal Primer for steel and wrought iron before topcoats. Rust-Oleum makes rust-preventive paints and primers for steel surfaces. Handrails are touched every day, and Dulux describes its gloss Weathershield as offering maximum durability and cleanability. Balustrade posts rusted through at the base need a safety repair before any painting, and our page on balustrade and handrail repairs deals with that work.

Ladders, Scaffolds and NSW Height Safety Rules

SafeWork NSW describes falls from heights as the number one cause of traumatic deaths in the NSW building and construction industry. The Work Health and Safety Regulation 2017, based on national model laws developed by Safe Work Australia, requires a business to remove the risk first where it can. Working from the ground, for example with extension poles, is the first choice under that approach. Where that is not possible, scaffolding, edge protection or an elevating work platform, a powered platform that lifts workers to the work, comes next, ahead of rope access systems and then safety nets. Under SafeWork NSW rules, a safe work method statement, known as a SWMS, is needed for work where a person could fall more than 2 metres. A SWMS is a written plan, prepared before work starts, that lists the high-risk tasks, the hazards and the controls the crew will use.

Scaffolding brings its own licence rule in NSW. SafeWork NSW says a person without a scaffolding licence must not erect, alter or dismantle a scaffold where a person or object could fall more than 4 metres. Its pre-use checks include a scaff tag, the inspection label at the scaffold entrance, showing an inspection no more than 30 days ago, and diagonal bracing on every fourth bay. Scaffolding for a two-storey home is estimated at $1,500 to $4,000 in 2027, and prices for taller homes appear in two-storey house painting costs.

Ladders can still be used for low, short tasks, and SafeWork NSW sets out how they should be used. Extension ladders should stand at a 4 to 1 ratio, with the base 1 metre out for every 4 metres of height, and extend at least 1 metre past the landing. The same guidance notes that workers fall from A-frame stepladders when they stand on the top two rungs or over-reach. On a steep block above Brisbane Water or a sloping lot at Kincumber, uneven ground can rule out ladders and lifting platforms, which pushes the job toward scaffolding. If a quote relies on ladders alone for second-storey eaves, check with the painter how the crew will meet these rules.

Decks, Fences and Fire-Retardant Coatings

Decks, pergolas, timber screens and fences can be painted or stained in the same visit as the house, which saves a second set-up. Decking takes foot traffic, standing water and sun on its top face, so it is finished with products made for decks, not the acrylic used on walls. Intergrain makes decking oils, timber stains and floor finishes, and Cabot's makes Deck and Exterior Stain in water-based and oil-based versions. Feast Watson makes matt look and wet look decking oils as well as a timber and deck stain. You will find preparation steps and recoat cycles for these jobs under deck staining and oiling and fence painting. In 2027 a deck stained or oiled is estimated at $25 to $50 per square metre, and a paling fence at $30 to $60 per metre.

Homes on bush fire prone land near the national parks sometimes raise the question of fire-retardant paint. The NSW Rural Fire Service has a fact sheet on intumescent paints, which are coatings that swell into an insulating layer when heated. It says any proposed use must be supported by a NATA certified laboratory test, NATA being the body that accredits Australian testing laboratories. The paint must also perform as AS 3959, the standard for building in bushfire-prone areas, requires. Timber with intumescent paint applied is not considered fire retardant treated timber, because the retardant qualities sit in the coating, not in the wood. The fact sheet says these products should not go on trafficable surfaces such as decks and stair treads, and the owner must pass the specifications to future buyers.

Reading the Data Sheet: Temperature, Dew and Recoat Times

Exterior paints come with a product data sheet, which gives application details, and a safety data sheet, or SDS, which covers hazards, safe handling and first aid. Painters follow the data sheet for temperature, drying and recoat times, because a maker's guarantee depends on the product being applied as instructed. The Dulux page for Weathershield Low Sheen gives coverage of up to 16 square metres per litre and a touch dry time of 20 minutes. It lists a recoat time of 2 hours at 25 degrees and 50 per cent humidity, and a minimum application temperature of 5 degrees.

Dulux warns that rain or overnight dew during drying may damage or remove the coating, and advises against painting on very cold or humid days. On the hottest days, it suggests painting the shaded side of the house. Painters working to that advice plan exterior coats so the film can dry before evening dew settles. A crew that stops work early on an exterior job may be following the data sheet. Graco makes airless paint sprayers, which can cover large walls quickly but need careful masking of windows, roofs and nearby cars. Paint spray can drift onto houses and cars next door on tight lots, so check how the painter will protect them.

Spread Rates and Dry Film Thickness on Exterior Walls

Dry film thickness is the thickness of paint once it has dried, measured in microns, which are thousandths of a millimetre. Each coat adds to that thickness, and protective systems for steel are specified by their total film thickness to reach a stated durability. For house paint, the practical control is the spread rate, the area one litre is meant to cover, because spreading paint thinner than that leaves a thinner film. Comparing the litres used against the area painted gives a rough check on whether coats were applied at the right thickness. Three hundred square metres of wall painted twice at 16 square metres per litre needs about 38 litres, so a job that used half that amount was spread too thin.

Colour changes affect how many coats a wall needs. Dark colours over light ones, or strong colours over pale ones, can need an extra coat to cover evenly, and that coat should be priced from the start. Tinting the undercoat close to the new colour can reduce the number of finishing coats needed for an even result. The quote should state the number of coats on each surface, the product for each coat and the colour, so the count can be checked.

Wash Water, Leftover Paint and the Stormwater System

Washing a house before painting produces dirty water carrying old paint flakes, chalky residue and grime, and cleaning brushes and rollers adds more paint to it. Stormwater drains carry runoff to creeks and other waterways, so anything washed into the street gutter ends up there. Under the Protection of the Environment Operations Act 1997, polluting any waters is an offence in NSW, and the NSW EPA lists wash water and paint among the things that pollute water. Brushes and rollers used with water-based paint should be washed where the water cannot run into a drain, and oil-based paint and solvents kept well away from gutters. Washing surfaces other than fibro needs the same care with runoff, and our guide to pressure cleaning lists the equipment. Kärcher makes pressure washers for home and professional use, and painters choose the pressure and nozzle to suit each surface.

Leftover paint should be kept for touch-ups or taken to a proper drop-off point, never poured into a drain or the garden. According to Central Coast Council, its Community Recycling Centre at the Buttonderry Waste Management Facility, 850 Hue Hue Road, Jilliby, lists household quantities of water-based and oil-based paint as free to drop off. Paint drop-offs there were paused for a time in 2025 and later resumed, so check the council's current drop-off arrangements before you take tins in. For other items the centre accepts and the council's rules on building waste, see our guide to hiring a handyman on the Central Coast. Agree in the quote whether leftover tins stay with you, labelled with the colour and the wall they were used on. Asbestos waste from damaged fibro is a separate matter, and a painter must not mix it with paint waste or general rubbish.

Diagnosing Peeling, Blistering and Rust Bleed After a Repaint

Some exterior paint faults appear within weeks, while others take a year or more to show. Peeling down to bare timber points to poor grip, which can come from paint applied over dust, salt, chalky residue or damp wood. Blistering can come from moisture behind the paint or from paint applied in hot sun, and cutting a blister open shows whether there is water underneath. Brown stains on new paint over timber can be tannin bleed, which a stain-blocking primer is meant to stop.

Chalking is a powdery layer on old paint that rubs off on your hand, and paint applied over it without proper cleaning can lose its grip. Rust spots coming through fresh paint on gutters or handrails suggest the rust underneath was not removed or primed. Cracking along the joints of fibre cement or weatherboards can point to failed sealant, or to movement in the building that paint cannot hide. Wide, stepped or growing cracks in render or brick need a builder or structural engineer before anyone paints over them. Take dated photos of any fault, note when you first saw it, and keep the quote, invoices and product names together. You can read about complaints to NSW Fair Trading and claims at the NSW Civil and Administrative Tribunal, known as NCAT, in our guide to hiring a painter on the Central Coast.

Guarantees from paint makers come with conditions that owners and painters both need to meet. The Dulux Weathershield residential guarantee, for example, covers peeling, blistering and flaking for as long as you live in the house, if the paint was applied and maintained as instructed. It excludes colour fade, failure of the surface underneath, and coatings from other makers used over or under the product. Dulux asks owners to keep the receipt and register the guarantee, so collect the receipts if the painter bought the paint. Workmanship warranties from the painter are separate from the maker's guarantee and should be written into the contract.

What to Look Out For in an Exterior Paint Specification

A good exterior quote is written as a specification, meaning a list that names each surface, its preparation, its primer or sealer and its topcoats. Watch for a one-line scope that says only to prepare and paint the exterior in two coats, with no products named, because it does not commit the painter to any product or preparation. Pressure washing listed for a house with fibro walls or eaves is a serious warning sign, since high-pressure water must not be used on asbestos. Metal near the sea should show the primer the paint maker requires, and steel balustrades should show rust treatment as well as topcoats. A two-storey quote with no scaffolding line, and no mention of how the crew will reach the eaves, does not show how the work at height will be made safe.

Very low prices can mean fewer coats, thinner coats or less preparation than the other quotes allow for. Check whether the price includes washing, filling, sealant, spot priming and cleanup, and whether leftover paint stays with you. Confirm the painter's licence and insurance before you sign, using the checks listed in our guide to finding a painter on the Central Coast. Request the product data sheets for the system quoted, because they show the coverage and recoat times the painter should be working to.

Collecting Exterior Painting Quotes That Use the Same System

Quotes can only be compared fairly if every painter prices the same scope of work. Walk around the house first and list each surface, from wall cladding and eaves to gutters, downpipes, windows, doors, handrails, decks and fences. Note which parts are fibro or might be, which are timber and which are metal, and photograph each elevation, including the hardest corner to reach. Tell each painter whether you want a colour change, because that can add a coat to every wall. In a strata building, the owners corporation, which is the body of all owners, may control the exterior, so read our guide to strata painting on the Central Coast first. If the house is a holiday home or rental, read our guide to painting holiday homes and rentals on the Central Coast for scheduling and tenant questions.

Ask each painter to quote the same paint system, or to explain clearly why they recommend a different one. Insist on a site visit, since only an inspection can show soft timber, rust and the condition of any fibro. Three written quotes give you enough to compare, and each should list preparation, materials, labour and scaffolding on separate lines. State-wide prices in exterior painting across NSW and the wider NSW painting services guide can be compared with the local figures on this page. Allow time between receiving quotes and signing, so you can check licences, insurance and the product data sheets.

Keep a job file once the work is finished. It should hold the signed quote, the colour names and codes, the product data sheets, the scaffold dates and any guarantee registration. Outdoor lights taken down for painting must be refitted by a licensed electrician, and you can find one through our guide to hiring an electrician on the Central Coast. If a balcony's membrane, the waterproof layer under the tiles, is failing, a waterproofer should repair it before any repaint, and our page on Central Coast waterproofing describes that work.
