Say Goodbye To Wasted Sealant And Adhesive Tubes - Use Every Last Drop!

[@andrewwilson3663]

Great tips. A 'slightly' less messy way to get to the good goo in a part cured tube is to just drill through the cured material to create a fresh path, flush the 'kerf' out and fit a new nozzle (and often the cured sealant plug will pull easily out of a used nozzle).

[@mickeyfilmer5551]

That's how I have always done it, and then cleaned the bit with acetone or Isopropyl alcohol (Whichever comes to hand first)

[@mikeenglish7063]

Snap. Cheapest easiest way to do it

[@nickbrown9895]

Me too. Can really fuck up the tube though but works.

[@CaribouKH]

I have a dedicated drill bit just for this 😉.. don't even need to fully clean that one.

[@mournfulmaurice2009]

That is a good one, never thought of that.

[@mdshovel]

I run a small building team in the NHS where we fit home adaptations including occasional wall mounted shower chairs and grab handles. We don't use enough silicone to warrant wielding a gun and had boxes of spare refills going off in the store or van. We now use toothpaste tubes of sealants - much more easily carried in a tool-bag and our spend has reduced by 75%

[@meetim6271]

Great in theory. I've found that the tubes are devilish hard to squeeze the stuff out. I bought them once or twice, never again.

I can't believe a didn't see the diy version! I put kitchen plastic wrap around the nozzle and squeeze a little bit of material from the tube forming a "blob cap" that gets trapped in the film sealing the tube, later I remove the dried top and its ready to use, so far worked fine for me. This is one of my favorite channels on yt, thanks for your content it's really informative and entertaining.

[@hermanussi]

Guys, just throw your opened sealant and adhesives into the freezer! It just works! You don't even need to close the nozzles or use condoms if you don't want to! The sealant/adhesives react with the water (humidity) in the air, not the air itself! A freezer is for the most part a zero humidity(no liquid water) environment. You will lose nothing by trying it! I've got sealant /adhesives in my freezer that is still usable after 7 years! Using the freezer even works for my opened superglue ( cyanocryalate) which is still usable after 3 years! Maybe Proper DiY could do a show and tell on using the freezer for preserving sealants /adhesives and CC!

[@Tonisuperfly]

Thank you!! I just bought an upright freezer, so have extra space. Last time I needed sealant, I cut a used cartridge in half. Do you let it sit to thaw before using, or does it stay pretty pliable? Are there any sealants that get wrecked through freezing that you know of? I know some paints and products say not to freeze. I’m assuming anything with water in it would potentially separate and form water crystals…

[@hermanussi]

Hi Toni. I have only put sealant, sealant adhesive and superglue in the freezer. It is cold coming from the freezer, but immediately pliable and useable on the intended surfaces! It's a nice feeling knowing that the sealant and CC is immediately useable when needed even after a few years! Good luck!

[@Tonisuperfly]

@@hermanussi well it’s worth it just for adhesives and sealants. Thanks for the reply

[@imqqmi]

Was going to say the same. If the freezer isn't working out, put the entire cartridge in a bag, put in silica moist absorber pack suck out remaining air and put a tight knot in it. Those rubber caps wont work for years, the seal around the nozzle threads and the plunger in the back of the cartridge aren't perfectly air tight but do seal for much thicker materials. Moist air still gets in and harden the silicone.

[@stefanogortaldi3156]

Seems a very good tip...I'll give it a go. Did you try with expanding foam?

[@MrJohnnyboyrebel]

I learned the hard way that silicone sealant has a shelf life regardless of the use and closure of the tip. Check the date code stamped on the tube. If the seal and is past its date code, throw it out. When you use old silicone, understand that it may not ever set. I found this out when sealing a new shower cabinet with my son. After four days, the silicone was still wet to the touch. After a little research, I discovered information about the date code. We literally wiped away the old stuff and replaced it with newly purchased silicone. Total success.

[@johnwarwick4105]

Never seen that but handy to know. Often had an old unopened tube set solid. Guess it’s like old plaster that can do the same ( sets very fast or not at all)

[@richardlewis5316]

Thats a very good point. For most jobs its by far best to use a new tube as it goes off more quickly which is important round sinks and shower trays which have to be used within hours. I tell my customers 'Never wipe it! as it makes ridges which never come out!

[@AN-kg4ei]

@MrJohnnyboyrebel I did the same thing when setting a sink in a vanity. What a mess. If the acetic acid evaporates, it won't catalyze or harden. I had never had it happen before and definitely learned the hard way.

[@AgentOffice]

Me too it never cured

[@fungames24]

Depending on brand. I had no-nonsense lasting years. Some ebay ones go solid after 1 year unopened.

You could as well take the cutoff part and clean that out heat it up a little and put it back on. No need to buy empty cartridges for that purpose. You could also take one from an empty cartridge that you used previously.

why cut the tube at all just drill a hole through the top until you reach fresh silicone

[@barryinn1778]

Here is a tip: try this method . Take the tip of tube dig out a little of the material at the tip fill the tip with vaseline , make sure no air is trapped in the tip when putting the vaseline in it, then cover with electrical tape, now the vaseline will keep the material fresh. This works great, I have been doing this for years. Now when you need it again the material will come out. I did like your idea about cutting off the top of tube and installing a new top, that's a good idea.

[@stevekirby5046]

The only problem I've found with sawing ends off a tube, is that you get plastic saw dust in the product. A nightmare if it's something you're trying to get a clean finish on. Keep up the good work.

[@JonasSolar]

It does help using a metal blade for finer plastic chips or if you have it, a hot wire cutter (used for cutting insulation).

[@larryg3038]

I’ve found a box cutter works best to cut the tube. Press the blade tip to penetrate the tube wall then slowly rotate the tube on the bench holding the box cutter steady. Just toss the dirty blade. Minimal cleanup and zero plastic bits in the caulking.

[@JonasSolar]

@@larryg3038 nice

[@sygad1]

Take the nozzle off, push a 150mm screw into the bottom to purge the content, wrap in kitchen paper and clean the nozzle. For the tube, I use a hot glue gun to seal the tube, works everytime and takes a couple of mins. Been using this technique for years

[@Tonisuperfly]

How long does the hot glue keep it fresh? Do you make sure there is no air gap between the sealant and glue? Do you put a blob on the end or squeeze some glue in the nozzle and leave it at that?

[@robertthomas6127]

@@Tonisuperfly ... Hello, Just be sure that the tip of the nozzel screw is clean and rougly 2 mm into the tube. I then set a plug of hot glue on it that looks simmilar to the original tube before one has opened it. It may well depend on what one is sealing, glue, sealant or what ever. As I stated above the last tube I repened was rougly a year old and still good.

What i tend to do is when I'm finished with the job and there's still adhesive left or silicone I push some out of the end and seal it with the stuff already in the tube. Come back to it at a later date and pull it out. Works for me

I do that with black silicone we use to seal engine housings. Pull out the hard sealer, pump out the dick cheese for a few seconds and you're back in business.

[@bigbunnyprojects10]

Hi Stuart, I’ve been using those caulk cap covers for well over a year. They do “nearly work”. I have had far better results combining taping the end of the tube and then fitting the caulk cap cover over the top. Another thing I do is cut off the ring tab around the tapered tube. This is for transport I think and that then allows the tapered tube to be screwed on more fully. One more thread.

[@LocostR1]

One tip if you have a decent compressor and want to unblock a nozzle, take the nozzle off and press the air blower attachment onto the nozzle end to make a seal and then blow the contents out. Make sure you aim it into a bin as it can make a bit of a mess!

[@ChrisMurley]

Brilliant! Can't believe it's taken this long for someone to show this. Kudos to you Stu.

[@figrollin]

I absolutely HATE wasting these. thanks for awesome tips for my tips!

[@3tree]

Great tips thanks Stuart. Looking at that last solution I suppose you could clean out the cut off end and flare that back over the end of the cut off tube for reuse, and just replace the nozzle with a new one, although sometimes the cone of cured silicon will pop out of the old one. Given the mess would be about the same it’s worth a try.

[@mikedunn7795]

I bought a pack of the condom style sealers,and so far,they seem to work well. I like the one where you cut off the end of the tube,and place an empty tube end over the end. That is the most common problem I have seen, a tube with dried product down about an inch from the end!

[@Legg99]

I tried the small latex 'condoms' as shown at time stamp 7:30 over the end of the nozzle. After two months in storage silicone in the nozzle had gone hard as usual, so I can't recommend those used in that way. It is worth noting that thin latex can be permeable to moisture and silicone RTV cures in the presence of moisture. So it's likely these let enough moisture through to start the curing process.

[@BromideBride]

I place a piece of thick polythene bag, [compost or dog food bags, even crisp bags will do], over the top and screw the nozzle back on just as demonstrated at 2:54. You might lose the nozzle or have to dig out any set sealant but the tube will remain useful for long over a year. There is some exhaust fitting paste I used to fix fiberglass tape to my woodburner just last week. That tube was bought in 2020 to repair a friend's bus exhaust during the lockdown. The nozzle is set like stone but under the plastic sheet, the tube is fine and probably will be for four more years. There's a tube of Crystal clear Stixall hanging by my bench dated 29th Sept 2022 that I use once every few weeks to seal small solar lights, still fully workable since I opened it back in Feb or March last year. I've done this for decades without it ever failing.

[@d3adlyBuzz]

12:41 tried something like this before with a heat shrunk 7up bottle. The pressure pushed the caulk back through the seal between the old and new surfaces.

[@maplecanuck6454]

Thank you for your input. I sometimes park a "long nail " (8")(1/8" wire with short slight bend) into end of dispensing nozzle and then tightly tape over all with "real" duct tape (the oowie, gooie type) (kept water & air out of ammo boxes) ...best results --so far.

[@stanionman8178]

Thank you for all these tips, very useful, I have thrown so many of these plastic tubes away with at least 75% of the contents still remaining, but had dried out, now I can hopefully keep these much longer and still be useful at a later date !

[@grepora]

In the US, most caulk/adhesive nozzles are fixed and not removable. A tip when working with dried caulk is to use isopropyl alcohol. It will dissolve the caulk (even silicon) so it can be wiped away. I put IA into a plastic squeeze bottle with a pivot top (not to be confused with a flip top) for easy application..

[@knockholt69]

In the States I use a fencing end cap - that happens to be 1 5/8” in diameter- perfect for the back end of the cartridge; which is then wrapped in good ol’ black tape. I also use a “Sharpie” pen to make hash marks on the lower end of said tube to indicate how much product I have left.

Now I live in Australia now and yes this has been a problem for me for many years and like you said have thrown away more than I care to think about it.

Hmm that replacement tube fix is a great idea too I have never seen this fix before now.

[@kathrynblack9152]

That video was worth 3 or 4 months of Patreon. Thunk of all the caulk tubes you will save inthe future. Thanks. I didn't know about the caulk cap (condoms) and the hint to cut the tube was good. I use a drill bit and drill down into the fresh stuff below the plug. And typically waste a lot of time cleaning out old nozzles when I should have spares on hand.

[@somewaresim]

Great tips, thanks a lot. I do very little DIY and it always seemed such a waste to throw away unused tubes.

[@gregdeitrick6073]

I wrap the tip with packing tape and then squeeze out material to fill the gaps under the tape. The material filling the gaps under the tape cure and help seal off the nozzle, and is also easy to clean off. Works well for caulks and sealants that are a bit soft after curing.

[@billclarke7893]

One thing to consider with stored/old tubes is any expiry date on the tube. I had the misfortune to use one which was out of date, the sealant line had lumps in which totally ruined the seal.

[@paulrutter5330]

I've been cutting the fingers off latex or vinyl gloves to use as mini-condoms for some time. Results are a bit hit and miss, but definitely increases drying time. I also have an old solid spiral corkscrew which I use to clear out clogged solid nozzles. Good vid!

[@caskwith]

Worth hanging onto used silicone tubes and nozzles, if you let them fully cure it's very easy to clean them out for reuse, never needed to buy an empty tube or nozzle this way. I've never thought to cut the top off a tube though, I have in the past drilled a hole in the side of a blocked tube and then squeezed the contents into an empty tube, that works well, just as messy as your method but a little more fiddly maybe. As for sealing nozzles I have also never really found a good method so just use electrical tape and expect to swap the nozzle. Silicone is the worst for clogging, acrylic products seem to keep find for months, maybe years with just tape.

[@mnmike6884]

Over a few decades of using various cartridges, I’ve never had one with a removable nozzle. I don’t recall noticing them or any mentioning of them at the multiple places I’ve shopped in. I’m betting that cartridges with replaceable nozzles are more expensive than non replaceable ones to the point it stays cheaper to just toss the cheap one rather than mess with repairing the more expensive ones.

[@garyl5128]

I wonder if you can re-use the top of the tube you cut off? Clean out the old contents, then heat it up and fit onto the remaining part of the tube. I've never tried that, but it might work. Could be worth a go before buying bare tubes. Might need a new nozzle.

[@AncoraImparoPiper]

What has worked for me so far is to simply remove the nozzle, take a knitting needle and poke around tube until I get deep inside. Once I reach the soft caulk, I just get a new nozzle and away I go on my merry way sealing up gaps again. I like the caulk condoms and will get a pack.

[@richardlewis5316]

I use another way to get at the liquid sealant in a tube where the top is solid - i drill through it with as large a drill as will go down into it. This has the advantage of reaching the usable silicone further down the tube, Buying things to save sealant will usually be more expensive than buying a new tube.

[@robertthomas6127]

A While back I started removing the nozzel before storing my sealants. I then seal the tip of the nozzel screw with hot wax or hot glue (which ever one prefers to call it). It has the same effect as if the tube was never opened. Just cut it off like you would with a new tube when you need it. The last tube I reopened was closed for approximately a year (I always write the rough date of purchase on sealants, paint, glue and soforth before storing them) and still functioned fine. 😉... Of course all these methods are only worth anything if cleaned properly before sealing the tube.

You can also use an old blunt drill and drill down through the cartridge until you reach the usable glue/sealant.

[@Dylan.299]

Enjoyed this topic as I hate waste but felt I had to add my own experiences on the subject. Using a screw to seal the nozzle doesn't work too well because all you are doing is changing the open ended tube for a smaller diameter open ended spiral 'tube ' formed by the thread void left by the screw as it sits inside the nozzle. This is why the ribbed (not threaded) plug is more effective. I use the cut-off fingers from old rubber gloves secured with wound on wire. It works pretty well but rubber is still slightly porous and eventually the goo will harden. Great suggestions from others in the comments.

i used those blue stoppers before, ended up getting stuck and when i pulled it out the inner piece stayed in the nozzle (which most of the tubes i get here in the states dont have replaceable nozzles), for your last tip i found something similar that you basically cut off the dried end of the tube and place it over it, acting like a new end and nozzle. Although i also run into issues where the back of the tube leaks so it squishes everything out the rear and nothing out the front lol

Great video! Love the condom! In the operating room, we use sterile condoms for the light handles above the bed. Even after 40 years, every time a surgery tech asks for one, someone snickers.

Two or four layers of clingfilm over the screw fitting, replace the nozzle screwing firmly tight. Sealant will not go off. I’ve got a bag full of old, unused nozzles, so replacement of clogged is not a problem.

I'll try some of these out! The nozzles in the US don't unscrew and are part of the main tube.

Does it fit

Skip to about the 12 minute mark where the useful information is - i did a 'thumbs up' on the video as that bit is really useful, 👍

[@shedworks3196]

Good idea but as you said cost over mess and it too much faffing about I would just replace, however the plugs are a good idea but i find that a new top is my best option

[@swiftwraith]

if you have a full tube of sealant thats gone off or even a large bung, theyre ideal for cleaning up belt/rotary sanders. Just use them like a giant eraser to rub off old crud

[@edmartin271]

Missed a vital top tip in the middle of the video there, always ensure you use a borrowed tenon saw to cut the tube of silicone 😜😂

I have a bucket in the shed with a few inches of water, just put the tube upside down in the bucket and they stay fresh. Just dispose of a little sealant when using it again to make sure no water is mixed in the nozzle.

Congratulations, regards from Athens Greece...😊

Some good ideas there, that I will be trying. . I use an old 8mm long Brad point drill , and drill through the blockage below the cap , give it a pump to push the stuff out and fit the nozzle. I normally get away with it. Cleaning the drill is a pig.
