I want to share my recent experience so that nobody else has to go through it. This metallic tape and it's caulk backing work well on the regular panels but there is not any room for it in the close tolerances of the doors. It was quite tight in the vent panels and impossible in the doors. I sealed all 8 door panels before trying to assemble the doors. I have painstakingly removed the aluminum tape and caulk from 5 of the 8 panels. It cost me a day of labor and had me saying things that I normally wouldn't. 3 more panels to go. Applying the tape was a piece of cake compared to removing it and it's caulk residue. I wished that someone had pointed this out earlier. Really. The frustration factor pegged when I realized the extra actions required to counter the initial extra actions of sealing the panels.

Hey John, thanks for showing which water proofing tape to purchase to seal the greenhouse panels!

So glad I found this video. I just built a green house, I installed rain gutter but somehow the water leak in the greenhouse. Can this tape work to tape the gap between gutter n poly panel ?

Merry Christmas John!

Happy Holidays John. thats some cool tape

UPDATE 2022: Home Depot as well as Menards and Lowes all carry the AntiDUST vent tape + sealing tape in a combination packet. It is the top of the line vent + sealing tape on the market and is the original vent tape by Multifoil. Aluminum will crack and tear allowing moisture and debris to enter the flutes of the sheets. You'll pay a bit more but it's worth maintaining the clarity of your sheets.

Thanks for the post, do you think that stuff would work for small hole repairs in pond lining? I've just got an allotment and want to restore the old pond I found there so newts and frogs can come back.

I need to do this for my panels. Here in Northern Cali my panels have been getting darker and darker. And while I thought it was dust on the surface, turns out that dust had been getting down INSIDE the panels and was acting pretty much like a shade cloth. I need to pull them all off and rinse them out before putting this tape stuff on.

Doesn't multi-wall polycarbonate need to breath. Isn't the correct dust tape designed to sealed at bottom and vented at top?

Thank you for this We're building our first greenhouse, the small Harbor Freight, this week. Bought it earlier than expected as Harbor Freight had a one-day special and it cost $239. I mean, wow, right? The big problem was not having a car to bring it home in, so I thought would need it shipped (talk about expensive). Rented a truck from Home Depot -- cost $25 for 70 minutes -- no upfront megabucks like U-Haul, just 25 bucks. So we're on our way. Thanks, John.

This video was made in 2011 and I'm wondering if anyone has used this tape outdoors and how it has held up over the last 10 years to the sun and rain.

I have a 2 cm gap on the bottom of my greenhouse, can I use quickset cement to seal the gap?

Excellent Focus control!

Hy Sir. I want to buy that tape for my greenhouse plastic because it's torn apart.

where were you like 6 months ago with this vid when i needed that stuff?! lol awesome vid, huge HELP any idea if anything about it may be toxic, for example if it was used in a hydro or aquaponics set up? would it leach anything bad that you are aware of?

I live in Australia, Today I went to our biggest Hardware store (Bunnings), they sell only 1 thing organic (compost) but its not even certified, to top it off I was looking for some ducting exactly like the ones behind you at :41 into the vid for 16.99, but Bunnings has no ducting whatsoever. Ive been there 4 times in the last week looking for different things and left with nothing. I wish Australia would get there act together.

Excellent ! Thanks !

Tuck Tape makes an 'Outdoor Repair Tape' which is clear, says it is made of UV resistant film and adhesive, good to -10 Celsius (but we get -40 sometimes here). It looks like it would be gos stuff to use. Thoughts?

Thanx John :)

Thanks this is one very inportent

Happy Holidays, John! How do you keep mice and rats away from your garden? Where do they come from? I never have this problem before.

my panel has come off completely. I wonder if I can use this tape to hold it back in place? so far, nothing has worked. ugh thanks!!!

Will this tape hold up at -20 degrees F? How often will I have to replace the tape?

Thanks

How much?

Hi I'm currently replacing the glass with twin walled polycarbonate on my greenhouse due to a change of regulation at my allotment here in the UK. I plan to seal & paint the panels black then fill the polly sheet channels with water across the north wall to help store some heat 👍

@LaoSoftware not sure but i heard human hair maybe works, i know it works for some pest just cant remember which ones and they come from all over in nature, rats and mice are all over, prob not a square mile of land on earth without some of those beady eyed buggers

I forgot to mention that I was assembling the Harbor Freight 10 x 12 greenhouse.

Nashua Waterproofing Repair Tape.

A video showing a greenhouse you used the waterproof tape on

Waterproof tape

I just some flex seal. And no leaks at all.

Thanks. Would have been better if you actually showed us how you sealed your glasshouse with the tape too.

you can get a clear waterproof tape

Use glass, not plastic!
