Questions and Answers for Nashua Tape 1.89 in. x 50 yd. 322 Multi-Purpose HVAC Foil Sealer Duct Tape

A:  Yes, just make sure the fixture is rated as enclosed can or you might need to change them out. If you do this make sure to use LED bulbs as lower heat to prevent overheating and fire.

A:  yes should work fine. they have wider tape if you have a bigger hole.

A:  Yes, this Tape is very effective in blocking holes and openings.

A:  Thank you for your question. Nashua 322 has not been tested for this use. While we are sure that the tape would stick, it is likely that any openings in your can lighting are likely there for a reason and should not be blocked without first checking with the lighting manufacturer. Best of luck with your project.

A:  The tape can take the heat, but i wouldn't do it. Those lights are designed to dissipate heat a certain way and if you block that it could potentially cause a fire or damage the light.

A:  Thank you for your question. Nashua 322 was designed for sealing ducts and insulation materials. While the foil surface would deflect much of the sun's rays, this tape has not been tested for longevity in a long-term direct sun exposure application such as you describe. A better choice might be a product like Nashua Waterproofing Repair Tape or a foil-backed flashing tape. Best of luck with your project.

A:  My experience with it seems that you would need the surface to be clean and dust free for it to adhere. I don't believe it would create a water-tight seal for your application.

A:  Possibly, but not well, and not for a long time. This tape is designed to be used indoors to seal the joints in duct work (and it does very well, at that). It is not intended to be exposed to the elements, and if it's applied to wood (which it doesn't do well), it will tend to trap moisture, and perhaps accelerate disintegration. If you wish, you might try lining the tops of the rafters with strips of self-adhesive rubber membrane (often called "Grace" in the roofing industry, HD SKU 204423144). This material would tend to be much more resilient for this application. It only comes in large rolls, so you might talk to a roofer to see if s/he has remnants of Grace available from a local job. That would help divert those remnants from the landfill. Good luck.

A:  No, I would install copper or stainless steel, depending on color needed. The flashing material section at Home Depot has many choices.

A:  This is a great product and is very sticky - it is also quite expensive - but I think for your purpose you want to use a flashband that is made for the purpose - this product is really made for sealing ductwork. There are several manufacturers of flashband and they all have a thick bitumen layer and stronger foil For patio rafters I have cut 6" flash band lengthways into two 3" strips to use on the top of the rafters and come 1/2" down the sides. You can also use Aluminum flashing which looks better I think

A:  The aluminum (foil side) may be okay if washed, but it is is very thin and the adhesive side is a very strong adhesive that extends to the edges which could be a problem. Clearly the tape is made to cover duct work and not made for possible food contact, so it is your call. I really have no idea.

A:  I would not wrap around any eadable product with this tape unless you wrap with good food wrap film first.

A:  Yes, the reflective side is aluminum and is not unlike aluminum foil that is used for wrapping foodstuff. After application, I would wipe down the surfaces with Rubbing Alcohol, which will sanitize them and remove any surface film.

A:  Thank you for your question. Nashua Multi-Purpose Foil Tape has not been evaluated for compliance with FDA requirements for direct (or indirect) food contact and should not be used for the application you describe. Best of luck with your project.

A:  I used to own a cake business, so I believe I am qualified to answer in that regard. I would NOT use a product such as this in any situation where food contact is concerned! I am doubt that the adhesive on this product is not food grade material and it certainly contacts he metal surface. There are inexpensive materials that you can use to cover a cake support structure that are food grade and would not cost more than this product. They can be found in hobby stores and big retail stores or can be ordered online.

A:  Some products are only available via on-line purchase.

A:  Wasnt what i expected. It was like foil paper with glue on one side

A:  for HVAC duct patching to reduce dust in to your ducts and improve air flow and efficiency to the HVAC system.

A:  Ask them, not me.

A:  Not, but it can be shipped there free mine is awesome

A:  No. This doesn't do well on irregular surfaces and doesn't really have much strength to tearing . Designed to seal duct seals where there will not be mechanical rubbing once installed.

A:  No

A:  No. It is like heavy duty aluminum foil that has a very sticky back that you access by removing a coated paper backing that is like wax paper to allow you to handle it. It is to seal ducts. I use it to seal up the joints in dryer discharge tubing. The tapes strength is in its adhesion properties. You can easily tear it by hand.

A:  It may but it wont look good

A:  I can't say for sure if it will or will not repair wicker. We used it for heat ducts, to seal the seams and such, and also to seal the dryer vent to the dryer.

A:  I would not recommend this tape for repairing a wicker chair for the following reasons: (1) the tape is fairly strong when adhering to a flat surface, but most wicker chairs have small, curved surfaces which would be difficult for the tape to conform to; (2) once you remove the release paper backing the tape will deform and crease while handling it and it would be very difficult to wrap it around closely spaced ribs, if that is what you're trying to repair; (3) the silver color stands out "like a sore thumb", unless you don't care about the appearance.

A:  Not really. In my experience, wicker is a great material, but it is very difficult to repair effectively. One possible method (depending on the damage) is to use a loop of wire (like a large paper clip) to gather the exposed canes to a fixed support, kind of like the way rebar is connected together (just on a much smaller scale). Maybe this video might help describe the overall idea: https://www.youtube.com/watch?v=ZmmXDXc3hAs. I love wicker, but don't have any because the kids used to think it was fun to pull it to pieces during supper. Good luck.

A:  No, it is not made for this propose. I would use some epoxy or glue to repair the wicker.

A:  no

A:  I'm not sure what you mean by "repair a wicker chair". I can tell you that I would not use this to repair a wicker chair at any point though since this is made for air ducts.

A:  Search on Internet shows not suitable for this application. "Nashua 322 HVAC Multi-Purpose Foil Tape. ... Made of durable aluminum foil, this high-tack tape adheres to surfaces to form an immediate seal and easily conforms to fit joints and corners. Designed to be moisture, mildew, UV, and mold resistant, it withstands temperatures of up to 200 degrees Fahrenheit."

A:  Nashua Multi-Purpose HVAC Foil Tape is rated for +40 degrees to +200 degrees F, so it will NOT be suitable for your application.

A:  I would not use this product for any purpose that involves food. The manufacture lists applications up to 200 degrees F. Cardboard has a flash point above 400 degrees F. So it is very likely that this product would off gas for the purpose you describe while the cardboard not catching on fire.

A:  Thank you for your inquiry. Unfortunately, Nashua 322 is not designed to withstand such high temperatures nor is it recommended for applications involving food. Best of luck with your project.

A:  Probably, I would not use this for food prep

A:  This forum is not a good place to get health and safety information. You should go ask that question directly of the manufacturer. It’s hard to imagine the average, or even professional builder who purchases at the Home Depot would know this kind of answer. If anyone answered, I would wonder how they could really know the answer.

A:  Sadly, this tape will likely offgas at the temperatures of a solar oven. This tape is not considered certified food safe, and so its use is not recommended in any process involving consumables. Sorry. Maybe try to build the oven using folded seams instead of taped for the reflector. Good luck.

A:  Yes. I bought it last week and installed it in less than an hour.

A:  We used this for our dryer vent, and it worked very well.

A:  Thank you for your question. Yes, Nashua 322 Multi-Purpose Foil tape is suitable for sealing connections of dryer vent ducts. For best results, ensure all surfaces are clean and dry prior to application. Best of luck with your project.

A:  Yes. Great tape for this

A:  Yes, better than regular duct tape which isn’t supposed to be used anyway per code.

A:  Yes. that's what i bought it for. Works good.

A:  Yes, I have used it for this purpose

A:  I did not like it. Adhesive came off on high heat.

A:  Yes that was the reason for my purchase to patch my dryer vent

A:  Yes, it will work just fine for taping seams or tears in the duct.

A:  I never used this on plywood, but my opinion is no, it will not hold. The label says "Applied to inorganic reinforced cement board". Since plywood is organic, probably will not hold. I used it on sheet metal duct work, and it is very sticky. Be careful to not let it stick to itself, almost impossible to separate.

A:  this tape has a very good adhesive quality. I have used it to seal gaps between metal ducting material and wood with absolutely no issues. I believe that if you have a clean smooth surface, this tape will adhere well.

A:  Thank you for your question. The tape will likely stick to the plywood but has not been tested or specifically designed for use on wood materials. As a result, Nashua cannot guarantee results. Surfaces should be as clean, dry, and smooth as possible prior to application. Best of luck with your project.

A:  Not very well. This tape is designed to adhere well to smooth, non-porous surfaces, like sheet metal. Plywood/OSB has an irregular and porous surface. This tape will stick to it somewhat, but not strongly, and it won't create much of a seal at all. Depending on your application, caulking or painting might work better to create a seal, or even to let this tape bond better (but still not well).

A:  Yes, if the plywood is clean, and free of wood dust, etc. What I generally do for porous surfaces like wood, is to fold over the edge of the tape about 1 inch so that you have a place to grab it for the next step which is conditioning: (1) apply a strip of tape over the area where you want to eventually have a permanent strip and gently smooth it down with the shiny side of the release paper that you had just removed to expose the adhesive; (2) grab the 1 inch folded edge and slowly remove the temporary strip of tape (what this step does is to pick up and dust and loose wood particles that are on the surface of the plywood) and reposition it over the next area that needs conditioning, until either you have conditioned ALL of the area that you wish to permanently cover with tape, OR, until the conditioning strip of tape is no longer sticky enough to effectively clean; (3) once ALL of the surface is conditioned, then apply a strip of fresh tape on the previously conditioned area and smooth down with the shiny side of the release paper, OR BETTER, use a Flexible Rubber/PlasticSmoothing tool.

A:  Yes, as with anything you will either get used to the smell as it is dissipating or you will roast the tape off the pipes.

A:  Thank you for your question and sorry for the experience you are having. As mentioned, use of Nashua 322 multi-purpose tape on a chimney pipe is not an appropriate use for the product as the tape is not designed to withstand such high temperatures (up to 200F intermittent temps only). The smell you experience is basically the burning rubber smell of the adhesive and we have no data available to indicate when it might dissipate.

A:  Eventually, after the organic compounds have burned off. It may take many fires for that though. Your best bet is to remove the tape and use some of that goo off cleaner to get the adhesive off

A:  No, used on reflectix insulation

A:  Well, ultimately all of the adhesive and tape backing will burn off and the fumes will go away, but they might catch fire in the meantime. The best thing to do would be to remove the tape from the vent piping, or reinstall the vent piping without the tape. The amount of time it will off gas and the danger of the materials catching fire depends on the application. Is this a flue for a furnace or water heater, or for a wood stove. Conventional gas or propane fired appliances will produce flue gases that are less than 450 degrees F. On the other hand, a wood stove can regularly produce flue gases at 1000 degrees F, well above the ignition point for most flammable materials. You will have to choose what to do, but err on the side of caution.

A:  I say yes

A:  I'm assuming you mean double wall vent, also known as 'B' vent, and, yes. this tape can be used to seal those joints, although the B-vent makes a pretty good seal on its own when properly installed. This tape is usually used to assemble laundry dryer vents because code no longer allows screws into the vent piping, so tape only. The maximum flue gas temperature for B-vent is less than 450 degrees F, but the outside of the vent pipe shouldn't get above 200 degrees F in normal application, so this tape will still perform properly, even though it is an off label use. If you suspect that the outside of the B-vent is going to heat beyond that point, you might want to use the premium foil tape (Internet SKU #100048600) which can operate to 325 degrees F.

A:  B vent (double wall) would not normally need tape. The sections interlock. You can use sheet metal screws at joints but only 1/4" so that they DO NOT penetrate the interior liner. If the diameter is more than 8" then you should use 4 screws at each joint. But no, the tape is not necessary. You should search online for B vent installation instructions. They must be properly attached at ends and through penetrations, and supported.

A:  You can use this for joint seams, but you might want to look at something more "permanent" and similar to Rutland 500°F RTV High Heat Silicone Sealant to reseal such things as the joints and storm collar. The Rutland product is a “tough rubbery adhesive seal and maintains its flexibility at 450°F continuously and 500°F intermittently”. Something more like this allows for contraction and expansion.

A:  No. It will not stick to brick or anything porous or organic.
