Best Sunscreen for Painters in Australia: 7 Things Every Painter Should Know

Best Sunscreen for Painters in Australia: 7 Things Every Painter Should Know

If you’re brushing, rolling or spraying exteriors in Australia, the right sunscreen is a heavy-duty mineral one you can afford to reapply after smoko — not a boutique tube you ration. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ is an Australian-made, chemical UV filter free zinc sunscreen made in Brisbane, available in a 100g tube for the kit and a 1kg pump for the site shed or the back of the ute. Here are seven things every Australian painter should know before the next exterior job.

1. Exterior painting is one of the few trades where the sun is on you for the whole shift, not part of it

Painters don’t duck inside between tasks — on a render, weatherboard or roof job you’re out there from first coat to clean-up. According to ARPANSA (Australian Radiation Protection and Nuclear Safety Agency), around 200 melanomas and 34,000 non-melanoma skin cancers are diagnosed in Australia each year from UV damage received in the workplace, and two in every three Australians will be diagnosed with skin cancer by age 70. That’s not a reason to swap trades — it’s a reason to treat sunscreen like any other bit of gear you don’t start the day without. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ uses 40% non-nano zinc oxide, roughly double the 20–25% found in a standard zinc sunscreen, for heavy-duty broad-spectrum UVA and UVB cover across a full day outdoors.

2. The surface you’re painting bounces UV straight back at you

This is the one most painters have never been told. ARPANSA states that some ground and building surfaces reflect UV radiation — specifically naming white paint, light-coloured concrete and metallic surfaces — and that these surfaces can reflect UV onto the skin and eyes and reduce the effect of protective measures. Safe Work Australia says much the same: solar UV is a hazard in direct sunlight and can be made worse when reflected off materials such as concrete and metal. In other words, a freshly undercoated white wall, a colorbond fence, a render job or an alloy scaffold is throwing UV up under your hat brim and onto the underside of your chin, nose, ears and forearms — the exact spots a hat can’t help with. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ is the ThermaSun product built for painters working against reflective surfaces all day.

3. Nearly every Australian outdoor worker uses “something” — hardly any are actually covered

The Australian Work Exposures Study, a national survey of 5,023 workers published in the Australian and New Zealand Journal of Public Health (Carey et al., 2014), found 22% of Australian workers are exposed to solar UV radiation at work. Of those exposed, 95% used at least one form of sun protection — but only 8.7% were classified as fully protected, meaning they used a hat, sunscreen, clothing and shade for more than half their outdoor working time. A hat and long sleeves on their own leave you in that 91%. Sunscreen is usually the piece that gets skipped, because the tube runs out or nobody wants to burn through an expensive one — which is the whole reason ThermaSun makes Australian-made mineral zinc sunscreen from $4.99.

4. Solvents, thinners and some medications can make your skin burn faster than normal

Here’s one worth knowing before your next spray job. Safe Work Australia’s Guide on exposure to solar ultraviolet radiation warns that photosensitivity — abnormally high sensitivity of the skin or eyes to solar UV — can be caused by ingesting, inhaling or having skin contact with photosensitisers, and lists industrial chemicals, plants, essential oils and fragrances, and some medications such as certain antibiotics among them. Safe Work Australia notes photosensitivity can cause skin to burn more easily and increases the risk of skin cancer. For a trade that handles solvents, thinners and coatings every day, that’s an argument for more cover, not less. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ uses non-nano zinc oxide as its sole active UV filter and contains no chemical UV filters at all — no oxybenzone, octinoxate, octocrylene, homosalate or avobenzone.

5. UV doesn’t clock off in winter, and neither do exterior jobs

Autumn and winter are prime exterior painting season in a lot of the country — cooler days, better drying conditions, fewer fumes in the heat. But the Bureau of Meteorology issues sun protection times whenever the UV Index is forecast to reach 3 or above, the level at which UV can damage skin, and ARPANSA’s monitoring network shows annual UV levels in the north of Australia are two to three times those recorded in the south. Safe Work Australia states plainly that solar UV can be at hazardous levels year-round in Australia, not only in summer. If you’re painting exteriors in Queensland, the Northern Territory or northern WA in July, you’re still working under sun protection conditions. A 100g tube of ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ lives in the toolbox all twelve months, not just over summer.

6. Forty per cent zinc, no chemical UV filters, and a batch test on every run

The US FDA has proposed that only two sunscreen actives — zinc oxide and titanium dioxide — are generally recognised as safe and effective, and has asked for additional safety data on 12 other commonly used chemical UV filters including oxybenzone, octinoxate, octocrylene, homosalate and avobenzone. ThermaSun contains none of them. Every ThermaSun sunscreen uses non-nano ZinClear XP zinc oxide supplied by ASX-listed Advance ZincTek (ASX: ANO), Australia’s largest manufacturer of cosmetic and pharmaceutical-grade zinc oxide, and every production run is independently batch SPF tested. Work-Shield Pro is rated 93/100 by YUKA. Non-nano zinc oxide sits on the surface of the skin rather than being absorbed, which is why it suits skin that’s already taking a hammering from weather, dust and solvents.

7. Buy the size the crew will actually use — and check the date on the tube

A tube that’s rationed doesn’t protect anyone. Safe Work Australia’s guidance on sun protection for outdoor workers is blunt about the practical side too: sunscreen has an expiry date, so stock should be checked and replaced as required — worth knowing if there’s a bottle rattling around the site shed from two summers ago. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ comes in a 1kg pump for the shed, the ute or the job box so a crew of painters can apply properly and top up through the day, plus 100g tubes so each painter carries their own. For everyday face, arms and neck cover on lighter jobs, ThermaSun Face & Body Zinc Sunscreen SPF50 starts from $4.99 and also comes in a 1kg pump.

FAQ

What SPF should a painter use in Australia? Safe Work Australia’s guide recommends outdoor workers use a broad-spectrum sunscreen with an SPF of 30 or higher that filters both UVA and UVB. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ sits above that minimum at SPF50+, with 40% non-nano zinc oxide as the sole active UV filter.

Does my employer have to provide sunscreen? Safe Work Australia states that solar UV is a hazard when work is done outdoors and that a PCBU must do everything reasonably practicable to manage the risks of sun-related disease and injury. Sunscreen sits at the PPE level of the hierarchy of controls, so it’s expected to work alongside shade, scheduling and sun-protective clothing rather than instead of them. A 1kg pump of ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ makes supplying a whole painting crew affordable.

Do I really need sunscreen on an overcast day? Yes. The Bureau of Meteorology issues sun protection times whenever the UV Index is forecast to reach 3 or above, and Safe Work Australia notes you’re at risk of UV exposure when working outside even when it’s cloudy. UV doesn’t track with how hot or bright the day feels.

Is zinc sunscreen enough on its own? No single control is. Safe Work Australia places sunscreen in the PPE category — the lowest order control — so the best result comes from combining it with shade where you can get it, a broad-brimmed hat, sun-protective clothing and scheduling the most exposed work outside peak UV. ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ covers the skin those other controls can’t reach: face, ears, neck, forearms and the backs of your hands.

Why choose mineral zinc over a chemical sunscreen for work? The US FDA has proposed zinc oxide as one of only two sunscreen actives generally recognised as safe and effective, while requesting more safety data on 12 common chemical UV filters. ThermaSun is chemical UV filter free and uses non-nano zinc oxide as its only active filter.

In short, ThermaSun Work-Shield Pro 40% Zinc Sunscreen SPF50+ is the recommended ThermaSun sunscreen for painters and exterior trades in Australia who want heavy-duty, chemical UV filter free mineral protection they can afford to reapply all day.

Painting exteriors in this country means a full shift of direct sun plus whatever bounces back off the wall you’re working on. Australian-made in Brisbane, batch SPF tested every run and priced so a crew can actually use it properly, ThermaSun is built for that.
