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.

FAQs
How does S-Fixx Adhesive & Power Work?
It works by using an extremely high concentration of cyanoacrylate (super glue) which reacts to the filling powder which causes the powder to bond together leaving a rock-solid mass.
How long does it take to cure?
It takes just 7 seconds for the full cure to take place.
What materials can it be used on?
Steel, Wood, Aluminum, Plastics, Copper, Rubber, Carbon Fiber.
Can I sand it down?
Yes, you can sand, file or even use an angle grinder to smooth down.
Can I drill or tap it?
Yes, you can drill or tap in just 7 seconds from curing.
Where would I use it?
Plastic clips, Car bumper, Fridge Shelves, Vacuum Cleaners, Alloy Crank Casings, Car Radiators, Toys, Printers, Laptops, Ceramics and much more.
Can I use an adhesive with the filling powders?
No, you must use the S-Fixx adhesive with the powders as traditional superglues have a gel effect, which means they will not penetrate the powders properly and will not leave the repair, desired.
What if I get the adhesive on my skin?
If you do by accident get the adhesive on your skin it is advised you bath the area in warm water or also try acetone to bring it off. If the adhesive goes in the eyes then you should seek medical attention.
How do I fill a hole when the powder just falls through?
Simply tape over the back with some tape and then fill. Once cured you can peel off the tape from the reverse side.
Can you paint over the S-Fixx repair?
Yes, you can paint over it with any type of paint.

Bought 2 used headlights but the brackets got damaged in transit, very easy to fix with this kit.
Seems like a very strong fix.
Hi David
Thanks so much for the great review – and for sharing the photos too!
We’re really glad the APX4 kit helped you repair the damaged headlight brackets so easily. It’s exactly the kind of strong, structural fix it was designed for, especially when parts get damaged in transit.
Appreciate you taking the time to leave feedback, and happy motoring! 💪
Ordered from these all the time. Their glue is hands down best I’ve ever used. They ship it quickly too
Used for various gluing and filling holes which then needed drilling and fixings installed. Absolutely does the job. If you're going to fill deep holes then you need to do it in layers. It hardened rapidly and resulted in super strong anchor. So many things like this don't fulfill their promises but this does. Just wish there were some more filling powder colour options and in larger quantities. Top top marks, Rob
