Frequently Asked Questions

Does Hot Stuff™ work on everything?
Almost any materials or combination of materials can be bonded with Hot Stuff glues.

How do I know which Hot Stuff™ to use?
Use Hot Stuff™ Original when the fit is very tight and the material is non-porous. (i.e. piece of plastic and a piece of flat rubber). Use Super 'T'™ or Special 'T'™ when parts don't fit well. (I.e. two pieces of unsanded wood) or for very porous materials such as the end grain of a piece of wood. Naturally, more porous material requires thicker glue.

How do I know how much glue to use?
A good rule of thumb is that one drop covers one square inch of non-porous material. Of course, more glue is needed if the material is porous and soaks up the glue.

How do I align the parts before the glue cures?
If the materials are relatively non-porous, do all the positioning first. Once a perfect fit is achieved, apply Hot Stuff Original to the joint. If necessary, Hot Stuff™ may be applied to more than one location along the bond line. Example: bonding two one-inch rubber cubes together. Four small applications, one at each side, would be in order.

Why doesn't the glue always dry instantly?
The more glue that is used in a given bond area, the slower the cure will be. For instance, a puddle of glue on a glass surface may not cure for hours. In these circumstances, instant glues tend to act like they're still in the bottle. Should a large quantity of glue be necessary, as with making a fillet, using our accelerators will cause an almost instant cure even in this extreme scenario.

How do I keep from putting on too much glue?

Remember the rule of thumb, "one drop covers a square inch", keeping in mind that more may be necessary to accommodate a poor fit, porous materials, or both.

What can I use in an emergency if I don't have fiberglass cloth on hand?

Practically any woven material, such as a T-shirt will work. Fiberglass and Kevlar, are by far the strongest.

How do I keep my glue fresh?
Bottles in use should be stored in a cool, dry area; extra, unopened stock in the FREEZER.

Do I need an accelerator?
Almost always, yes. This doesn't mean that you'll always use accelerator, but once you've used accelerator you'll find you don't want to be without it.

When wouldn't I use accelerator?
In situations where the glue is applied first and some positioning time is necessary.

What is the difference between 'Hot' and 'Mild' NCF™ accelerator?
'Hot' NCF™ accelerator cures the glues much quicker. The choice between 'Hot' and 'Mild' is usually a personal preference. As a general rule, if you tend to use mostly HOT STUFF™ Original (the fastest HOT STUFF™) and Super 'T'™, we suggest 'Mild'. On the other hand, if you tend to use the thicker, slower Special 'T'™, we suggest the 'Hot' formula.

Why do I need solvent?

With glues this strong, it is always wise to have a bottle of solvent on hand. Unbonding misaligned parts and removing glue from fingertips are common uses of Super Solvent.

Is Super Solvent™ a thinner?
No. Super Solvent™ is only meant for dissolving cured glue. Any foreign material mixed with these glues (i.e. using this solvent as a thinner) will cause an unstable condition resulting in a decrease of bond strength and shelf life.
