A long shift on a roof, slab or roadside crew can mean hours of UV exposure before smoko. Sunscreen for tradies is not a cosmetic extra or something to save for beach days. It is daily personal protective equipment that helps reduce skin damage and the risk of skin cancer.

Australia has some of the highest UV levels in the world, and outdoor workers can receive many times the UV exposure of indoor workers. The risk does not disappear because the morning is cool, the sky is overcast or the job is partly shaded. UV radiation can still be high enough to damage unprotected skin.

For tradies, the challenge is choosing a sunscreen that can handle sweat, dust, movement and long days, then using enough of it often enough. The best product is one you will apply properly, reapply on site and combine with other forms of sun protection.

What sunscreen should tradies use?

Choose a broad-spectrum SPF 50 or SPF 50+ sunscreen with water resistance. Broad spectrum means it protects against both UVA and UVB radiation. UVB is closely associated with sunburn, while UVA contributes to skin ageing and can also play a role in skin cancer.

Water-resistant sunscreen is particularly useful for physically demanding work. Sweating, wiping your face, climbing in and out of a ute, and rubbing against clothing all reduce the protection left on the skin. Check whether the label states two or four hours of water resistance, but remember this does not mean you can apply it once at breakfast and forget it for the rest of the day.

A sunscreen approved for supply in Australia should carry an AUST L or AUST L(A) number on the label. This indicates it is regulated by the Therapeutic Goods Administration. Avoid relying on imported products with unclear labelling or products marketed only as moisturisers or cosmetics unless they meet Australian sunscreen requirements.

The format matters less than consistent, generous use. Creams and lotions make it easier to see where you have applied product. Gels may feel lighter on hairy or oily skin. Sprays can be convenient for arms and legs, but they are easy to underapply and should be rubbed in after spraying. For the face, a non-greasy formula that does not sting the eyes may make reapplication far more realistic.

How to apply sunscreen for tradies properly

Most people use far less sunscreen than the tested amount. A thin layer may feel economical, but it does not provide the SPF printed on the bottle.

Apply sunscreen 20 minutes before starting work or heading outdoors. For an average-sized adult, a useful guide is about seven teaspoons for the whole body: one teaspoon for the face, neck and ears; one for each arm and leg; and one each for the front and back of the body. If your skin is exposed, it needs coverage.

Pay particular attention to the places tradies commonly miss: ears, the back and sides of the neck, temples, hairline, scalp if hair is thinning, forearms, hands and the tops of feet when wearing open footwear. Lip balm with SPF 50+ can help protect the lips, especially for workers who spend most of the day outside.

Reapply at least every two hours. Reapply sooner after heavy sweating, towelling off, washing your hands repeatedly or rubbing against PPE and clothing. A practical routine is to keep a full-size bottle in the lunch room, site shed or work vehicle and a smaller bottle in your tool bag. If it is visible and easy to reach, it is more likely to be used.

Do not leave sunscreen in extreme heat

A bottle sitting on the dashboard or in a hot metal toolbox can be exposed to extreme temperatures. Heat can affect the texture and stability of a product over time. Store sunscreen out of direct sun where possible, check the expiry date, and replace bottles that have separated, changed smell or texture, or are well past their use-by date.

Sunscreen is one part of site protection

Sunscreen matters, but it should not carry the entire load. On a worksite, the most reliable protection comes from combining it with clothing, shade and work practices.

Long-sleeved, tightly woven work shirts and long trousers provide a physical barrier without needing reapplication. For consistently outdoor work, consider garments with an ultraviolet protection factor, or UPF rating. A broad-brimmed hat with a brim that shades the ears and neck offers more protection than a cap. Where a hard hat is required, attachable neck flaps and brims designed for the helmet can be useful if they comply with workplace safety requirements.

UV-rated wraparound sunglasses protect the eyes and delicate skin around them. Shade structures, canopies and covered break areas also matter. They are not complete protection, because UV can reflect from concrete, metal, water and pale surfaces, but they reduce direct exposure during breaks and stationary tasks.

If your team can plan work, schedule the most exposed jobs for earlier or later in the day when practical. Check the daily UV index rather than judging risk by temperature. In much of Australia, sun protection is needed whenever the UV index is 3 or above. This can occur well outside summer.

Making sunscreen routine on a busy worksite

The barrier is rarely a lack of knowledge. It is usually pace. When a delivery is late, a pour is underway or a client is waiting, sunscreen can feel easy to skip. The answer is to make it part of the routine, not an optional decision each day.

Apply it before putting on your shirt, high-vis and PPE. Reapply at morning tea and lunch. Supervisors and leading hands can help by making sunscreen available alongside drinking water and first-aid supplies, and by treating sun protection as ordinary site safety rather than a personal preference.

For employers, providing sunscreen is a sensible measure, but availability alone is not enough. Workers need adequate time to apply it, options that suit different skin types and clear encouragement to use other protective clothing. A greasy sunscreen that makes hands slippery may not suit every task, so workers may need a fast-absorbing formula for exposed areas and gloves or long sleeves to protect the hands and forearms.

Some people avoid sunscreen because it causes stinging, breakouts or irritation. That does not mean sun protection is not possible. Try a fragrance-free or sensitive-skin formula, and use a sunscreen designed for the face around the eyes. If you develop a persistent rash or swelling, stop using the product and speak with a pharmacist or doctor about suitable alternatives.

Watch your skin, not just the weather

Even excellent sun habits cannot erase past exposure. Outdoor workers should know what their skin normally looks like and act on changes early. Skin cancers do not always look like a dark or dramatic mole.

Book a medical assessment for a spot that is new, changing, itchy, bleeding, crusting, painful or not healing. Pay close attention to a sore that persists for more than a few weeks, a scaly patch on the face or ears, or a mole that changes in size, shape, colour or sensation. People with fair skin, many moles, a personal or family history of skin cancer, or previous significant sunburn need particular vigilance, but skin cancer can affect people of all skin colours.

Do not wait for a routine day off if a lesion is changing quickly or repeatedly bleeding. Early assessment can make treatment simpler and can save lives. A skin check with a qualified clinician is the right next step when something does not look or feel right.

The practical goal is not perfection. It is building protection into every outdoor shift: SPF 50+ on exposed skin, enough product, regular reapplication, protective workwear and prompt action when your skin changes. Your trade may be hands-on, but protecting your skin is work worth doing before the day gets away from you.
