Customer Questions & Answers

Do you remove the paper backing when using this tape?

I noticed that both the foil and the paper backing have an adhesive on them. They come apart easily, but are you supposed to apply them together?

Only the foil

can you paint over this foil tape

Asked by: Anonymous
I have not personally tried to paint over the product. I would guess that paint could go over it, but I am uncertain how well & how long the paint would adhere due to the smooth, metalic surface.

2.5 in. x 60 yd. 324 Amp Premium Foil UL Listed HVAC Tape is rated 4.3 out of 5 by 75.
Rated 4 out of 5 by from Good stuff Bought this to tape up some leaky ducts and it worked well. It is difficult to peel the foil from the paper backing especially after cutting with scissors. It stuck well to he duct work even in some dirty areas. Be careful as the foil will slice you. I learned the hard way. No gloves needed though.

Rated 5 out of 5 by from This is a multi use product. Not just for ducts but also will seal caulk tubes for longer than a year! This tape will seal caulk tubes for over a year, just peal it off and use.

The tape around my duct work on the on the AC unit was almost complete loose. This Premium Foil Tape was very effective in sealing the old tape to the duct. I applied it about a month ago and so far it is holding well. Caution: when you peel the back off the adhesive, your tape will quickly coil into a loop and stick together. Be sure to hold both ends when removing the backing. Since I was working alone, I would remove a few inches of the tape, stick the exposed end to a stud or duct, and then finish removing the backing.

Otherwise a good product and have plenty left for the next job of mine or a friends. The strength and the stick is very good and easy to work with. Watch out for it to curl if you pull the backing all the way off a 2 foot length or so. I had a piece stick to itself and had to toss it. My bad upon trying to finish the job a little to quick.

Easy to shape on round flexible ductwork to repair and seal holes or tears. Great for sealing up drywall openings for ductwork, securely fastening rigid to flexible ductwork, and patching leaks in seams.

It adheres well and I hope it will stay in place. However it is rather expensive and I only needed about 2 ft to do the job. I am not sure why they not carry smaller rolls at more affordable price.

This product I picked up last week was perfect for sealing my metal dryer vent line. Very high quality and easy to use. The only con is it's a little expensive but I have used other foil tapes and this is by far the best.
