J-B Weld ExtremeHeat and Blue Magic QuikSteel have different purposes for surface use. ExtremeHeat is suitable for materials that need to be repaired at high temperatures.
On the other hand, QuikSteel is for quick repairs in different applications. It cures fast and can deliver an instant repair at any time, much like the J-B WaterWeld and PlasticWeld comparison shows for rapid fixes.
To learn more, check out the detailed comparison below.
Article Highlights
- J-B Weld Extreme is great for repairing small gaps, cracks, and holes.
- QuikSteel mixes like putty and bonds like epoxy.
- ExtremeHeat has a high-temperature resistance and can do indoor and outdoor repairs, which can be compared to J-B Weld TankWeld and SteelStik, both of which handle tough environments.
- QuikSteel is a lot quicker than ExtremeHeat.
Detailed Comparison
J-B Weld ExtremeHeat is a temperature-resistant metallic paste formulated to repair metals, steel, and iron in high-temperature environments.
On the other hand, the QuikSteel epoxy putty is a steel-reinforced epoxy that claims to have a consistency like putty and create a bond like epoxy.
To learn more details, check the comparison below.
Tensile Strength
The J-B Weld ExtremeHeat has a tensile strength of 800 PSI. But the Blue Magic QuikSteel is as strong as 5950 PSI. So, QuikSteel is stronger.
Temperature
The J-B Weld ExtremeHeat is a temperature-resistant metallic paste that can withstand heat to 1000°F / 537°C). It is non-flammable and contains no solvents or volatile organic compounds.
Another product is QuikSteel standard putty that can withstand up to 500°F/260°C.
Set & Cure Time
ExtremeHeat’s setting time is just an hour, and it takes around 24 hours to cure adequately. Once cured, it can be drilled, sanded, and machined.
The QuikSteel, however, sets in only 5 minutes and cures in 1 hour. It can be used underwater, drilled, filed, tapped, sanded, machined, and painted.
QuikSteel can cure while ExtremeHeat is set, so it is a much faster setting and curing product than ExtremeHeat.
Cure Color
ExtremeHeat’s cure color is machine gray. On the other hand, QuikSteel dries gray. So, they are pretty similar in this sense.
Compatible Materials
J-B Weld ExtremeHeat can be used on multiple materials, such as metal, aluminum, iron, and steel.
QuikSteel works on several surfaces, including aluminum, ceramic, PVC, UPVC, plastic, fiberglass, glass, brass, cast iron, metal, wood, alloy steel, galvanized steel, copper, vinyl, and almost anything except rubber.
So, Quiksteel is more versatile in terms of compatible materials to use this epoxy.
Applications
ExtremeHeat is a good option for repairing iron, metal, and steel components in high-temperature environments. Its organic repair paste effortlessly fills cracks and holes.
It works well on exhaust manifolds, mufflers, tailpipes, ductwork, engine blocks, fireboxes, heat exchange units, outdoor grills, water heaters, and more.
On the other hand, the QuikSteel claims to mix like putty and bond like epoxy. It can repair tile, flooring, furniture, masonry, countertops, woodworking, carpentry, landscaping, and more.
Also, it can work on exhaust manifolds, catalytic converters, mufflers, exhaust pipes, fireboxes, industrial, home, office furnaces, heat exchange, crossovers, and many more.
In this case, we can see that both products have different purposes and are used differently. Some of the purposes are the same, but the ways of working differ.
Resistance
ExtremeHeat has an excellent heat-resistant formula. It is also a waterproof, water-based product that can work on indoor and outdoor projects.
When it comes to QuikSteel, you should know that it bonds underwater. It is water resistant, NSF-61, and safe for drinking water.
Editor’s Note
We concluded that We QuikSteel is stronger than ExtremeHeat based on all the features and information.
Although ExtremeHeat is suitable for any high-temperature repairs, QuikSteel is more versatile.
Furthermore, QuikSteel is much faster than ExtremeHeat. So, QuikSteel is for quick repairs, and ExtremeHeat is for high-temperature repairs.
