Cabinet Painting near you

SafeWork NSW lists isocyanates among its priority chemicals and describes them as a group of highly reactive organic compounds that easily become volatile and enter the atmosphere as a vapour, found in polyurethane coatings, foams, elastomers and plastics. The health effect that matters is sensitisation: SafeWork NSW states that sensitised workers may suffer allergic reactions including occupational asthma, dermatitis, hives and rashes at very low, or brief, exposure to isocyanates, and that chronic exposure may cause liver and kidney disease, chronic lung damage and cancer.

Sensitisation is permanent and unpredictable. A person can work with these products without trouble and then react to a trace exposure afterwards, which is why the controls are engineering controls rather than personal caution. SafeWork NSW points to the hierarchy of controls, eliminating the use of isocyanates where practicable and otherwise using engineering controls including local exhaust ventilation, automated processes or spray booths, with full-face respirators and a program to fit, instruct on and maintain that equipment.

SafeWork NSW also states that health monitoring should be provided to workers where there is a significant risk to health from isocyanate exposure. That is an occupational regime, and it is the clearest signal that two-pack cabinet spraying belongs in a properly ventilated workshop with trained operators, not in a home kitchen with a fan in the window. If a contractor proposes spraying two-pack in your occupied house, ask exactly how the space will be extracted and who else will be in the building.

Workshop spraying is the benchmark. Doors and drawer fronts go to a controlled space with proper extraction, are sprayed and cured flat, and come back hard. The kitchen is out of action only at the beginning and the end, the dust and odour stay out of the house, and the finish is the closest to factory. The trade-off is time, since the kitchen runs without doors for the period in between.

On-site spraying suits carcasses and fixed panels that cannot be removed, and it can be done well with masking, extraction and the right product. It is also where corners get cut most often, because containing overspray properly in an occupied house takes longer than the spraying does. If the same contractor is spraying doors on site rather than in a workshop, ask why.

Brush and roller work is the honest budget option. With good products and careful technique it can look tidy, and it avoids overspray entirely. What it cannot do is hide texture, so it suits a satin or low sheen finish on flat panels rather than a high gloss on shaker doors. Deciding which of these three you are buying is more important than the colour.

The lifespan of a cabinet repaint is set almost entirely by adhesion and by cure. A coating that keyed properly to a primed melamine face and was allowed to harden fully before the doors were rehung behaves like any other kitchen finish. A coating applied over a greasy, glossy, unprimed face will look excellent for some months and then start shedding at exactly the points that get handled.

The failure points are predictable. Door edges near handles chip first, because that is where fingernails and rings land. The area around the sink and dishwasher blisters, because steam works into any unsealed edge. The cabinet above a cooktop discolours and softens from heat and oil. And any vinyl-wrapped door that was already lifting at a corner will keep lifting under a coating, since paint does not glue a film back down.

Curing deserves particular attention because it is invisible. Many coatings are touch-dry in hours and fully hard in weeks, and during that gap a door pressed against a bumper or a drawer front closed hard will mark. Ask the contractor for the product's full cure time and treat the kitchen gently until it has passed.

If the kitchen is original to a house built before 1970, the joinery and the walls around it may carry lead paint. LeadSmart NSW states that lead paint was used in most homes built in Australia before 1970 and that lead paint can be dangerous even before renovations start, for example when it chips off around windows and doors. Its advice is that if the paint is in good condition, leave it alone or paint over it, and that wet sanding and wet scraping are the safest methods of preparing a surface for painting or removing old lead paint.

Where old paint has to be disturbed, LeadSmart NSW calls for an AS 1716-approved respirator or mask fitted with P1 or P2 filters and coveralls, an industrial or HEPA vacuum cleaner that is not used for day to day or household vacuuming, and renovation waste sealed in heavy-duty plastic sheets or bags and disposed of at an approved part of the local waste facility. This is a reason to have a professional handle preparation in an older kitchen rather than to sand it yourself.

The second unknown is the wall behind the cabinetry. The national asbestos product register records asbestos cement flat sheeting used for interior walls and ceilings prior to 1990, lists behind stoves among its uses, and warns that nine and twelve millimetre panels can be mistaken for plasterboard, particularly if painted or wallpapered. If the job involves removing panels or cutting into a wall in a pre-1990 kitchen, that has to be assessed before anyone starts, not during.
