Purus Ceramic Guard 500ml – ceramic SiO₂ spray coating

Purus Ceramic Guard 500ml – Deep shine & long-lasting ceramic protection

The Purus Ceramic Guard 500ml is a spray-on ceramic SiO₂ coating that offers up to 6 months’ protection against dirt, water, UV radiation and acid rain. Each bottle provides an average of 8 to 12 full treatments, making this one of the most cost-effective ceramic protection products on the Dutch market. It is applied panel by panel using a microfibre cloth — without the need for professional knowledge or equipment.

Imagine this: your car is sitting in the driveway, freshly washed, but the paintwork is missing that final touch that makes the difference between clean and truly impressive. That’s exactly why Purus Ceramic Guard was developed. No hours of waxing or complicated treatments — simply apply and buff. Within minutes, you’ll create a deep, wet-look shine and an extremely hydrophobic ceramic protective layer that effortlessly repels dirt and water for weeks on end.

What Ceramic Guard 500ml is and why it works

Purus Ceramic Guard is an advanced spray-on ceramic coating based on SiO₂ technology (silicon dioxide). Whereas a traditional spray wax simply sits on the surface and wears off quickly, Ceramic Guard forms a molecular bond with the car’s paintwork. The result is an extremely hard, water- and dirt-repellent protective layer that withstands UV radiation, road salt, bird droppings and acid rain for months on end.

Thanks to its powerful water-repellent properties, water beads up and rolls straight off the car, preventing dirt from sticking. This means your car stays clean for much longer and makes washing it a lot less work. The product is suitable for all car paints, wraps and existing ceramic coatings — and also works as coating booster to extend and reinforce an existing professional layer.

Purus Ceramic Guard 500ml versus the competition

In terms of duration of protection and value for money, Ceramic Guard 500ML clearly stands out from alternatives such as Meguiar’s Ceramic Wax and Turtle Wax Ceramic Spray. Both of these alternatives are American products with a shorter duration of protection and a similar or higher price per treatment.

Step by step: how to apply Purus Ceramic Guard 500ml correctly

The result depends entirely on the preparation. A clean, grease-free surface is essential for maximum adhesion and a streak-free finish. Always work in the shade and on a cool surface — above 35°C, the product dries too quickly, increasing the risk of streaks.

1. Preparation: Wash the car thoroughly with Purus Super Wash and dry the car thoroughly. Make sure the surface is free from grease and dirt.
2. Application: Spray 2 to 4 sprays of Purus Ceramic Guard directly onto a clean microfibre cloth — never spray directly onto large surfaces.
3. Distribute: Using the cloth, spread the product in an overlapping criss-cross pattern over one panel at a time.
4. Rub off: Immediately use a second, dry microfibre cloth to polish the panel until it has a streak-free, deep mirror finish.
5. Curing: After application, it is best to leave the vehicle to dry for a few hours to allow the ceramic coating to cure properly. Avoid exposure to rain for the first 2 hours.

Safety warning: Avoid contact with the eyes. Keep out of reach of children. Do not use on hot surfaces (above 35°C) or in direct sunlight. The full Safety Data Sheet (SDS) is available on request from our customer service team.

Long-term maintenance: what to expect after application

After the first treatment, you’ll notice the effect most clearly in the rain. Water forms into tight droplets and, at speeds above 40 km/h, largely slides off the paintwork. This effect gradually diminishes over time — not all at once.

When washing, use a pH-neutral car shampoo and avoid brush machines with hard bristles. These break down the coating more quickly than rain or sunshine. A hand wash or tunnel wash using soft cloths is ideal. If you want to maximise protection, apply a new layer of Ceramic Guard as a top coat after 3 months — this will maintain the water-repellent properties without you having to start from scratch with decontamination.

Common application problems and how to solve them

• Stains or streaks after rubbing: This usually happens when the surface is too hot or there is too much product. Use a clean, slightly damp microfibre cloth to smooth the area and wipe it dry straight away.
• Sub-optimal water beading: The paintwork was probably not completely clean or free of grease. Decontaminate the paintwork — for example, using a clay bar or an iron remover — and reapply Ceramic Guard.
• The product sets too quickly: You are probably working on a hot or sunny surface. Move the car into the shade and wait until the paint has cooled down.

Myth vs. fact: what’s really true about ceramic spray coatings?

• Myth: Ceramic coatings are intended for professional detailers only.
  Purus Ceramic Guard brings professional SiO₂ technology to an easy-to-use spray format. Anyone can apply it streak-free without the risk of permanent damage.
• Myth: You don’t need spray wax or a coating if your car already has a ceramic coating.
  Purus Ceramic Guard is the recommended maintenance product for use as a coating booster on existing ceramic coatings. It instantly restores and enhances the water-repellent properties.
• Myth: A ceramic spray will keep your car scratch-free.
  No spray can make a car completely scratch-free. Purus Ceramic Guard, however, does provide a smooth protective layer that helps prevent fine wash marks and micro-scratches.

What customers say about Purus Ceramic Guard 500ml

Average: ★★★★★ 4.9/5 based on 154 reviews

• Dennis K. – Zwolle | ★★★★★
  “What a bizarre effect. Rain-X on the windscreen is nothing compared to this; the water simply flies off the bonnet at 50 km/h. It’s easy to rub on and the deep shine on black is fantastic.”
• Sanne T. – Breda | ★★★★★
  “I’ve been using it as a topcoat over my existing coating. My car has been looking as shiny as if it’s just been polished for two months now.”
• Jeroen V. – Rotterdam | ★★★★★
  “It’s much quicker to apply than traditional wax and it simply lasts much longer. I’d definitely recommend it.”
