Resin Anchors - The Absolute Strongest Fixings

[@captainwaldo]

The last 3 seconds of this video had me in stitches. Your comedic timing is on point

[@georgepritchard3010]

There have been quite a few comments regarding the wisdom or not of using a blower and brush to clear the holes before filling with resin. As someone who has installed literally hundreds of resin bonded anchors, I can assure you that the method shown using a blower and brush (which ideally should be a round one) is 100 percent the correct way to do it. With a vacuum you cannot guarantee to remove all the dust which can cause failure of the bond. This may seem odd, but if you download the tech info sheets from the manufacturers you will find it is in fact the correct method.

[@ProperDIY]

Thank you George.

[@matthewhuszarik4173]

Blowing out is always more effective than sucking out with a vacuum. The velocity of the air it many times higher.

[@RB-bl7vq]

[@Rajsta78]

After filling a hole, is it possible to drill into the resin as opposed to fitting into non cured resin? I ask as I need to fill a large door frame hole and the torque the screw through it into the cured resin.

[@slowmarchingband1]

In a former life I ran a sign manufacturing company. In 1996 we hung a 2 ton sign above the entrance to Kingsland Shopping Centre in Hackney using 2 vertical resin anchors with 16mm rods. Terrified me for years, but they held, amazing strength.

[@MylesDavid]

BWAHAHAHAHA!! Did you drive by it often looking at it just waiting for it to fall? 😬😬😬

[@slowmarchingband1]

It did keep me awake at night sometimes. Thousands of people walked under that thing every day. It's long gone now though, and I don't do that kind of stuff any more😅

[@ProperDIY]

Nice one

[@Jammydodgers41]

I can relate slightly. I'm a drainage engineer and install 6 inch cast iron pipework in carparks. I use a fixing called drop in anchors (shots). They need a 12mm hole and a punch with a setting tool. They hold a ton each. Does worry me though still lol

[@user-te1le7ck6b]

As a resident of hackney thank you 😊

[@garulusglandarius6126]

Honestly Stuart, your videos are far superior in content than ANYTHING on mainstream. You’re demonstrations, explanations ( how AND why ) are exemplary ! I genuinely get excited when I’m alerted to a new proper DIY. I hope you continue for many many years, I suspect you don’t realise ( as you’re a decent humble man ) just how valuable your videos are. If I could subscribe again, I would. Thank you 👍

[@paulstannett465]

I entirely agree. You always answer the next question in my mind without me even having to ask it. Thank you ever so much Stuart, keep it up!

[@bunning63]

Totally agree with the five minute work time, it's get everything ready, check and go. Have used a compressor for blowing out holes, real effective but watch your eyes or do it your way. Incidentally have found if you're quick enough you can but the pointy end of the applicator into the end if a garden hose and flush out the product. Works well enough to be able to reuse them a few times.

[@afnankhokhar5578]

Stuart, I can't explain how well timed this video is for me. I am forever grateful. Thank you

Fabulous video. Clear, concise and, with the inclusion of a smattering of humour, very memorable. Keep up the good work and thank you.

[@karma3101]

I've always shied away from using resin anchors in the past, thinking they might be to messy or complicated. I'll definitely be giving them ago in the future. Thanks for the video.

[@ProperDIY]

No problem

[@andrewslattery403]

Thanks for another great video. I've used these types of fixings on a number of occasions, although I do normally turn the threaded rod fixings in an anti-clockwise when locating them. I find that this avoids the 'archimedes screw' effect which might try to pump the medium from the hole.

[@richardhall5489]

Years ago I installed about 100 Hilti anchors with eye bolts in a yoga studio. They were for rope yoga - where the anchor has to support somone's weight. As such they were subject to the LOLER regs as a piece of lifting equipment. About a year later I needed to get some of them load tested for insurance purposes. I went back to the Hilti store and they remembered me and orgasnised a test free of charge! The test rig performed a pull test, it was a bit like a bottle jack with a force gauge. Passed no problem. Great service, you wouldn't get that from Screwfix or B&Q.

[@s.faccenda674]

Hi Richard, the Hilton store are good guys. You do know that Screwfix is the Tradesman’s outlet of B&Q eh?

[@johnmeldrum891]

Worked with Hilti tools and fixing for years when they were trade leaders, nowadays there appears to be similar cheaper options around, but don’t quite make the grade

[@GeeWhizRS]

Nice one Stuart. I would put the air nozzle at the bottom of the hole to blow it out properly. I’ve taped an 8mm tube on the end of an oil syringe and just use that to blast the holes clean. Works really well. I do use a bottle brush to loosen debris prior though. 👍

[@Christopher_T_Paul]

It's great stuff, I usually really only ever use it for mounting bathroom basins, threaded bar and a nut is an amazing fixing for them, you would be surprised the nonsense that happens ontop of a basin, especially in a public bathroom.

[@jamesmatthews291]

Thanks for this, Stuart - I've got a 75" TV to wall-mount on plasterboard and was wracking my brains as to how to do it with conventional metal wall anchors. I'll definitely be giving this stuff a go. It's usually a bonus having a wife who doesn't understand the difference between inches and cm; just not when she buys a telly without measuring and expects you to fit it!

[@UltimateAccuracy]

Used on Large wall hung patio awnings, TV brackets and a garden gazebo which gets significant wind loading. All still there! great stuff, it's the most permanent of fixings. Tried breaking a test lump with a sledgehammer, broke the engineering brick it was sat on.

[@isthisthat]

I've seen a carpenter use these for anchoring floating shelves. Best and easiest method by far

[@StCreed]

That's very helpful if you want to stack a few elephants on those shelves. A bit of overkill for anything else, though. I used normal wall anchors to put up a fitness bar for my son. Two anchors can hold about 4000 kilograms of weight. I'm pretty sure that resin anchors are even stronger. But mine are removable :)

[@d.k.1394]

My wife weighs 100kg and i glued her to the ceiling. So these products really work

[@neilphilip2320]

Simply excellent - about to fix a pillar drill to my workshop floor - and this is how I will do it. Many thanks!!

[@steady803]

Thanks mate exactly what I need, I have never realised that resin was that strong. I will use it to secure a new fence post to a wall. Thanks again Stuart

[@ProperDIY]

No problem

[@madgebishop5409]

never even crossed my mind to try resin fixings like this, will be definitely giving this stuff a try next time something needs attatching to something else

[@davideyres955]

This is great stuff for securing in to old breeze block. Had to fit a large feature radiator to a wall in my 80s build house. The supplied rawl plugs pulled out of the holes, tried big metal fixings and they did the same. Chemfixed some threaded bar and bolted on and it’s never moved. Great stuff.

[@stuartday1876]

Saw this video when it was released, but came back to it exactly for this! I'm hanging a 3 column radiator on the wall and want to be sure it's going to be safe. This is what I'm going to use. How is yours holding up, 2 years later?

[@stevewilliams6191]

Thanks Stuart, that was a really interesting and informative video. I've looked at resin fixings before but never knew much about them. After watching your video I can definitely see me using them at some point.

[@kevinrogan9871]

This technology was used more than 50 years ago when providing support in underground mines holes 50+mm in diameter would be drilled into the backs for a couple of meters, a few plastic cartridges of rotaset would then be pushed up the hole by the rock bolt which would then be spun to crush the glass tube of hardner, when the epoxy stiffened up a 6” square metal plate would torqued down against the rock mass. Very effective, but a bit costly, they were often superseded by using deformed bar or long lengths of steel cable placed into the hole that was grouted with a cement grout. The cable bolts were often in excess of 20m and made working in wide stopes much safer. I also used the glass vial type 30 years ago to secure wide span portal frames to their foundations.

[@apostolos55goulandris97]

Nice Video, Thanks I Once had to take out such a resin-anchored bolt and after many failures the only thing that worked and helped me remove it was a blowtorch... Heated it enough to melt a bit and quickly pulled it out. After all the effort and tries, it felt like cheating, but did the work... Just keep that in mind if you ever need it, and definitely if the area and the load are fire sensitive

[@johnvine5731]

Good tip. I've saved this for later!

[@pauljohnson4590]

We had a high wire act in our pantomime, and the company who supplied it had fabricated massive steel plates which were fixed to the wall either side of the stage. The steel cable was then attached, running at about ten feet above ground, and tightened with a Tirfor winch. The guy then had a tensioned cable to walk across. I can't imagine the tension on each wall, but at the end of the ten week run, they removed the plates and ground off the studs, and nobody even knows it was there!

[@bell6446]

Excellent video clip. Thank you for showing the product, installing the fitting and performing realistic tests as demos. I’m impressed with the chemical anchors and will add this option to my choices for similar applications. I was impressed with the difficulty your miter saw had in getting through the hardened material. It looks really abrasive; planning the installation so as to avoid trying to modify it later appears the best approach. 😊

[@rodgerq]

Good video! First time I used these was a couple of summers ago tying down some step handrails. If it's hot out, working time can really be limited so it pays to keep the tubes either indoors or at least in the shade until ready to use.

[@Dave5843-d9m]

Put the blower straw almost to the bottom of the hole. Just as you did with the resin nozzle. The hollow wall sleeve looks great. You can improve support under the board by drill a few holes through the drywall and inject some more resin. That stops it collapsing when nut/bolts are tightened.

[@somewhereelse3813]

Brilliant demo, brilliant engagement, wasn't expecting the ending. Brilliant 👏👏👏

[@ProperDIY]

[@TheRonskiman]

I thought this was a serious video, until I saw that toothbrush! You do realise that that you can buy proper brushes pretty cheaply, and they do a much better job. I think this video came up because I double checked the instructions earlier today. I fitted 24 M8 studs today into a wall, using the 410ml cartridge version of the same stuff, only used the one nozzle. It's brilliant stuff, been using it for years, no struggling with fixings, no cracking bricks etc, I've even fixed electrical back boxes in place with it. Impressed with the tightness test.

[@jota3732]

Hi Stewart I’ve used this system to put a scaffold poll across my garage wall to wall into brickwork ( 8 foot long ) it holds two bags 1 x 70 kg and 1 x 20 kg , they have been up for about 7 years , it still amazes me how much punishment this gets and it’s as strong today as it was when I first put it up definitely recommend this .

[@watcherofwatchers]

I used some resin anchors to secure a large safe into a basement wall/floor. They worked fantastically.

[@HouseFairyDIY]

Cleaning out with the toothbrush is a good tip! I tried to install an awning brancket with expanding anchor bolts, but my brickwork mortar started to crack. I've bought some of this injectable resin to fix some thinner bolts. I'm going to use extra large washers. Hopefully, this will do the job!

[@russellwaite2768]

best one I've ever used is a product called Anchorset , it comes with a special nozzle that mixes it for you so you just stuff it in the hole and insert your threaded bar or whatever, wait about 20 mins or so and it will NOT come out unless the wall falls down. I used it to anchor my lean-to shed to the side of my house. Awesome.

[@anthonyhoughton6625]

Nice one fella. A much appreciated video as I'd never come across this fixing type until today whilst researching post base anchors. Perfect for me as I didn't want to add high expansion pressures to the blocks I've just used to build a wall in the garden.

Some top tips here to help avoid my usual bodgery. Many thanks!

[@SeanFitz-vo4fm]

Excellent video. One minor comment: To clean the drilled hole, instead of a toothbrush, I would prefer a small plumbers wire brush, the type used to clean inside copper fittings before soldering. I think the abrasion is greater and the cylinder shape might do better than the toothbrush.

Of 10 x 12mm x 150mm through bolts, eight are good... delighted to know now what to do xT

We fixed steel columns to concrete footings with these epoxy anchors all the time. One day the excavator backed into one of the columns and pulled it out of the footing. Interestingly it wasn’t the epoxy that failed though, it was the surrounding concrete of the footing that failed. Each of the anchors pulled out a perfect cone of concrete right out of the footing. The bolts remained fixed in their epoxied holes.

[@robgullen]

Having first used the "plug in" glass inserts about 40 years ago I would recommend them for the amateur/DIYer as you have a much more leeway to drill all your holes and get the job ready - and no waste as with the gun cartridges. (I often stop and think about subsequent users of the, about 50, shop premises where I used the fixings (probably 20 or 30 per location) got on with removing the 8mm studs!!)

Great video I was thinking of putting a more permanent gazebo type structure onto a patio. First off I was thinking of taking out four slabs digging down two feet then setting posts in with postfix and cutting the slab to go over the post. Lot of messing around and overkill as I'm. Only building a square frame at the top and covering with corrugated plastic or whatever Then I thought spike shoes but again messing around. Finally post shoes bolt down type with expansion bolts but might just crack the slab? Maybe just ordinary threaded stud and resin down hole then bolt down with nut?

[@David-xc4us]

I’ve used these for years, original had to pour the one liquid into another then shake for a minute or 2 and u could feel the pot heating up but the newer method that mixes it in a gun makes it so easy….with the going off timings I found that the room/outside temperature u r using it in makes a difference….the warmer it is the quicker it goes off

didn't know about these until i went to my local B&Q and was advised by a member of staff to use it on exactly what you said...a failed gate post where the hole for the anchor had become weak...the gate hasn't moved a mm since

[@MarvinofMars]

The normal rule for anchor is fill the hole 50% of the depth, but to achieve this some suppliers have caps that fit over the nozzle , SPIT sell these as separate item, very handy and leave a tidy job. I have made the same wrapping tape on the nozzle, when you doing 15 to 20 starter bars, no waste exact bar to resin is key.

Excellent demonstration. Thank you.

[@RO8s]

First time I used these was to put in a mezzanine floor into a barn conversion I was doing. So, holes in stone, all cleaned and prepared and holes already drilled in the beam that would be fixed to two walls (i.e. one corner of the barn). So the bolts had to go through the beam into the wall, since once they set in the wall, if they moved a fraction in the hole, you'd never get them into the holes in the beam. Good old panic once I started, because five minutes is the outside time! Once set, they held the whole floor without effort. Now I use them all the time. A couple of days ago, I was doing some fixing on my sister's roof and noticed that two of the concrete vent-bricks on top of her chimney were cracked and were actually held in place with wire, and since I had some over and time running out, I squeezed some of this into the cracks - using it like glue! Went up yesterday and they are absolutely solid! So you can use it to glue concrete, brick or whatever. Miraculous stuff. I did wonder what those plastic tubes were for in the last one I bought, a couple of weeks ago, and now I know!

[@handyjim]

great video used this to hold up my porch been up about 5 years now and not moved a mm great stuff

[@ProperDIY]

[@emmabird9745]

Very interesting. How sucessful are you at cleaning the tube to be able to use some more, say next week? Given the solidity and short working time, might I suggest that, if you have a multi hole fitting to hang that you have it ready so that you can position it on all the studs so that it pulls them into place while soft and save the effort of enlarging/slotting holes in the fitting later.

[@duffharris9295]

Why doesn’t everyone use this all the time? I can’t believe how great this is.

[@C4sp3r123]

It would be interesting to hear if you were able to use the stuff left in the tube? I had hoped you would mention that at the end of the video. I have used these fixings once before to fix tiles to the bottom of the arch of a window to provide a decorative overhang/drip tray. Applied a blob to the tile, held it in place with a bit of wood wedging the tile in place for the 5 minutes or so it took to go off. It worked really well but we did need to be organised and ready in advance and having a second set of hands really helped. It bonded the tiles in place really well when we didn't really have any other option. Expensive but it has its place and uses which makes it worth the money.

[@raydebbiemcdonald3208]

Perfect timing, I was thinking of using this to mount some small posts to a 6 inch high brick wall for a 12 inch picket fence. Going to secure rebar into the brick and drill holes in the posts to slide over the top. It’s only small and that will hold it in place and mean I could just lift it out to repaint it.

[@C4sp3r123]

I agree with the other person who commented. Your idea sounds like overkill and will be quite expensive. A simple solution for your need of such a small fence would be to use screw inserts. Fix your small posts with rawl plugs and screws to the brick wall, then drill and using an allen key insert the screw inserts. Then use some bolts to attach the fence into the screw inserts. You can then undo the bolts holding the fence in place to paint it time and time again and you always have a good fixing to put it back into. They work really well and hold strongly and cost very little from Screwfix etc.

[@MylesDavid]

Great video! One thing that might a good idea instead of using spray air to blow the dust out of the hole is to simply use a vacuum with a hose. It just helps to keep the dust down. 👍🏼😊👍🏼

[@emmabird9745]

Even better idea if we could have a thin tube vacuum attachment to concentrate the suck and maybe get in the hole (bit ambitious that last bit). I find normal vac nozzle helps but does not clear the holes.

These are like "2 pack" Epoxy glue, superior in every way, apart from convenience, to the rest of the products on the shelves. My grandad always used "2 pack" glue and until recently, I always used "Super Glue" and found it lacking. Only recently I started using "2 pack" and have never looked back. Only time I use "super glue" is on the most minor of applications.
