Blackout can be applied onto Steel, Wood, Aluminium, Plastics, Copper, Carbon Fibre, Ceramics, Stone, Brick, Glass and more!
Blackout is designed to convert rust into a stable compound and prevent further corrosion on metal surfaces. It is particularly useful for surfaces that already have rust or corrosion, as it chemically reacts with iron oxide (rust) and transforms it into a protective layer. Once applied Blackout is touch dry in just 30 minutes with full cure time taking around 24 hours.
Chemical Conversion: Blackout contains an active ingredient that chemically reacts with the iron oxide in rust, converting it into a more stable compound.
Stabilises Rust: The chemical reaction transforms the rust into a black or dark blue substance, often referred to as ferric tannate or iron phosphate. This stable layer helps prevent further oxidation, effectively halting the progression of rust.
Primer Properties: Blackout works also as a primer. Once the rust is converted, the paint provides a primed surface suitable to be over painted with another paint type.
Easy Application: Blackout is typically easy to apply with a brush or roller. It can be used on various metal surfaces, including iron, steel, but also on plastics, wood, glass and more.
Versatility: Blackout is versatile and can be used in various sectors, such as automotive, fences, railings, machinery, woodwork, DIY, garden & craft. Blackout can withstand temperatures of -40c to +240c
Long-Term Protection: When used properly, Blackout can offer long-term protection against rust formation. However, it's essential to follow the instructions regarding application. Blackout will remain permanently flexible and resistant to further cracking.
How To Apply: It is important that the surface being treated is properly prepared and structurally sound before application. While we have tested the product on a wide range of materials, it is impossible to test on every possible surface. For example, certain woods may contain oil-based additives or be pressure-treated (tanalised), which can reduce adhesion.
Some plastics can also contain a high oil content, which may prevent proper bonding. In these cases, thorough sanding to create a keyed, roughened surface will significantly improve adhesion and overall performance.
We always recommend carrying out a small test patch first and allowing it to fully cure before proceeding with the entire area. This ensures correct adhesion and confirms the final finish meets your expectations.

We’re delighted to hear that you’re pleased with BLACK-OUT and found it to be a very good product. It’s always great to receive such positive feedback, and we really appreciate you taking the time to share your experience.
Thank you for choosing S-FIXX, and we hope BLACK-OUT continues to help protect and restore your projects for years to come.
Saw the demo on QVC about a month ago and thought I’d give it a go.
Very impressed with coverage and hardly any drips.
Will be getting more to paint shed.
Thank you for the 5-star review!
We’re thrilled to hear that BLACK-OUT impressed you on your pergola project. Great coverage and minimal drips are exactly what we designed it for, so it’s fantastic to know it delivered for you.
It’s always rewarding to hear when customers see the demonstration, give it a try themselves, and achieve such great results. We hope the shed project goes just as smoothly, and we look forward to helping with that too!
Thank you for your support and for taking the time to share your experience.

I have 2 cast iron man hole covers in my driveway thought this would be ideal to refresh them as they are 60yo and were rusty.
I took them up gave them both 2 coats back end of last summer of Sfixx Rust Converter and here we are 7 months later rust is coming through already !!!

I used this to paint our rusty garden BBQ, paint black door hinges on our motorhome, paint a steel frame in the garden, an unglazed ceramic bowl. Once I used it I realised how versatile and useful it is. Lovely consistent matt finish with just one coat. Best to decant and keep lid on main pot during hot weather. The plasticised paint goes around curves and cracks wonderfully and it's water tight afterwards. Don't know how I managed without it! Can think of loads more uses.
Thank you so much for this amazing review, Mrs Hatcher! 🙌
We absolutely love hearing all the different ways you’ve used Blackout — from the rusty garden BBQ and motorhome hinges to the steel frame and even an unglazed ceramic bowl. That’s exactly the kind of versatility we designed it for.
It’s great to hear you’re getting a lovely, consistent matt finish in just one coat, and your tip about decanting and keeping the lid on in hot weather is spot on.
We’re delighted Blackout has become one of those “can’t live without it” products for you, and we really appreciate you taking the time to share your experience.
Thank you again for choosing S-FIXX!
I bought a tub to see if it matched the hype, and it does, I`ve been trying to sort a budget fix on some gutters to save the charity some money without having to take them all down and start again. This did the trick and so far no more reports of drips, I also used it on the wooden gate which were beginning to crack but this seems to have sealed them also. So I`ve just ordered two more tubs when I got a deal from them, The only thing is that they said they had `white` on the website, but they haven`t had any for years. A great pity becuse I have a job for it where black will not do. So I`m looking for something to do that with, but obviously not at Flexi Coat.

Painted my garden chairs, they had chips and odd patches of rust.
This paint goes on so easy and you end up with such a professional finish, they look wonderful.
I bought this product to see if it was as good as the presenter’s said. Well it was absolutely amazing it covers in one coat and the finish looks amazing and professional!! I’ve used it on metal and wooden doors this frame is 30 years old looks like new now

I have bought this paint before because it dose the job that other paints can’t cover now my neighbour has asked me to purchase him some he has bought 3tins so far
I have purchased this paint more than once because I find it so good for all those jobs outside that you literally want to give a face lift to. Great for painting those old plant pots, one coat completely transforms them.
Does what it says on the tin. Covers in one coat. I used this on my rusty chiminea.
The matt Black finish looks great. It doesn't drip, run and it goes a long way
Have purchased my second tin if this wonderful stuff.
It's spruced up some tired looking garden furniture, given them a new lease of life.
About to embark on revitalising a chimney I'm sure it will look as good as new too.
Easy to apply,
clean brushes in just water.
I highly recommend this product. 5*
Used this paint on our fences and wooden garden benches. So very easily put on with a roller and paint tray. We also used brushes between the slats in our fences. Being a water based paint the brushes were so very easily washed out afterwards. I bought 6 tins of this great paint from the shopping channel QVC and I’m most definitely going to buy more of it as soon as it becomes available again. I just want to keep some extra on standby for touch up next year. Absolutely Brilliant Paint. Well done SFIXX . I’d very highly recommend it.
Very good, only problem, there is no info on cleaning brushes after use, nothing at all, tells you what to use it on, and that’s it, apart from that, very pleased with outcome, would certainly recommend it
