When customers ask me to fit a floating shelf on drywall I generally tell them NOOOO!! Drywall just isn't capable of supporting the large leverage forces that get applied though the bracket - fine for light things like ornaments but if you want to use these shelves for really heavy books you're going to run in to problems. The official IKEA specs say no more than 5kg on plasterboard but I wanted to put together a quick test to see what they can actually withstand given worst case scenario of a point load right at the frong of the shelf. Could they handle the quoted 5kg? Let's find out!

Great video. I've always figured this would be the way a shelf mounted to drywall would fail, but I've never seen it demonstrated in this way.

I've been a sign installer for 30 years and you must be able to imagine how many different fixings of used inside and out but I still find your channel extremely interesting and I wonder what the significant difference would be if you had added one screw to the centre of that bracket into the right hand stud so the screw is Centre up and down as well I would like to see you try this if you could and ID like to see the difference from what you've done today to what that result would be thank you

Hi Andy, again a fantastic demonstration. Thank you for this, the loads you are working with are commonly known as point and UDL loads, the point load being the one you are testing with your load measuring gig which is the worst type of load that can be applied to any condition, the other load you spoke of the 5kg is a ULD load which stands for uniformed distributed load which would be the load the shelf can take safely if loaded in compliance with manufactures recommendations. Regarding the bracketry being bent by 3mm I have found that certain bracketry from other suppliers have a top and bottom with the top be elevated to compensate for settlement. Again, good demonstration and I look forward to the next one.

@FireAngelOfLondon 5 лет назад

5Kg is probably right for long term use. This is an instantaneous failure test, not a long term test and I am glad that you pointed this out near the start of the video. Shelves are for decades of use not for five minutes. I am someone who tends to build most things over-strength. I am also fortunate to live in a flat that has only one small plasterboard wall, the rest are solid brick as the building is over 100 years old. That plasterboard partition is also in a place where I would never want to put shelves on it so it really isn't going to be an issue.

@jakefallon2335 5 лет назад

Nice job Andy and very worthwhile with very interesting result. I've always advised against floating shelves on plasterboard and have even refused to fit them as I didn't want any comebacks. Nice to see what happens to the expanding bolts which are my go-to fixing in plasterboard for anything remotely serious. Keep up the great work.

@GosforthHandyman 5 лет назад

@movax20h 5 лет назад

I agree with the safety factors. I often put over 100kg on shelf brackets, or table legs, that are rated to 50kg (at midspan). As long as they are very well attached to wall, the bracket will not fail, and it will be not deformed or damaged in anyway at all. But I will not put that much weight permanently, because failure of one screw or slow creep, thermal expansion and contraction of metal and wood will make it eventually fail.

Maybe you should make a test on strength of new drywall compared to "old" drywall? I assume that they would weaken over time due to humidity and so on. Btw we(Sweden) usually use 60 cm c-c here for drywall so that might also affect your results. I'm quite surprised by the result though. Keep up the good work!

Thank you for the video. This is exactly what I was looking for. I brought a couple of Lack shelve today. For some reason the metal bracket feels flimsy , like I can easily bend it with bare hands. It doesn't feel metal at all, feel more like plastic. Wondering if the quality is different here in Canada then UK.. Also, can you recommend screws to go with it for mounting it on studs. Should I reenforce the shelves with L-brackets

@strobie42 5 лет назад

I love these tests, inquiring minds want to know! :-) I wonder if there is an even slightly worse case if you apply your point load to the left or right end though, rather than the middle - maybe some extra leverage that way?

@adriana-2788 2 года назад

Does this apply to plasterboard glued to the actual wall too? I fitted 3 of ikea shelfs to one (110cm shelves) and put books on 2 of them. I did not use expanding plugs just your usual wall plags ( 7 in each shelf). Its only been 2 days so I hope this holds as I have a 200l fishtank underneath (Lord please). I am planning to do the same on other side of chimney so hope this wont destroy the plasterboard!

@jonathanvaughan942 3 года назад

Thanks for this. I've got a 1.9m lack on order. It's to go on a dot and dab wall with only about 10mm gap between the plasterboard and blockwork, so too shallow for a wall anchor. I wanted to use corefix but whatever the blocks are don't drill easily. Are grip its an option, if the weight is under 10kg and the load isn't near the end of the shelf?

@geetarwanabe 3 года назад

How did it go? Is it flimsy? I've been seeing horror stories about how much flex these shelves get. I've been assuming it's just idiots with no idea how to mount shelves properly.

@danburch9989 5 лет назад

It's really a test of the drywall and the drywall anchor. Unless the IKEA LACK was made of light gauge sheet metal, it would never fail before the drywall or anchor.

@crispy6532 Год назад

and therefore, since the source of the load is on the same drywall as the shelf, the force applied through the loader should counteract the force on the tested board in such a way that the drywall may not show signs of stress or break when it ought to...which means this test may not be useful at all.

@movax20h 5 лет назад

What conincidence, I was just fixing IKEA Lack shelve (used as shoe / boots storage above the floor), because it was poorly installed, and started bending / deflecting from being level. It was mounted by 5 plugs and screws. I used all 10 holes instead, used new plugs, and filled all holes with gipsum, waited 10 minutes, hammered plugs until they are flush, then waited few hours before hanging the bracked and the shelf back. Now it is rock solid. (This is in old conrete, but I think it is not full concrete, and most likely a concrete blocks, that are hollow inside, or something else, because it just doesn't feel like it).

@GosforthHandyman 5 лет назад

The lower screws don't offer much in terms of strength due to the leverage forces on the upper screws. 👍

@leestewart1848 5 лет назад

Hi, new to the channel & subbed. Great video!! I was wondering how many studs you used behind the test rig? it seemed like you used 2, but I guess in a real world scenario a shelf situated in-between studs would get support from 3 (i.e both ends). The fail appeared to occur on the end where no stud seemed to be supporting the board?? wouldn't that be the weakest point

@GosforthHandyman 5 лет назад

Yeah, 2 studs - I didn't have a piece of plasterboard big enough to do 3 😀 - in reality I don't think it would make much difference to the result - the other side failed more towards the bracket than the edge. 👍

@leestewart1848 5 лет назад

Good point, never noticed :-S. Thanks for the reply, look forward to viewing all your previous. Love a UK channel! #thumbsup

@GosforthHandyman 5 лет назад

Cheers Lee! 👍

@GuiltyMalice 4 года назад

If you turned the bracket around the bars would have bent. The bending occurs at the set screw point on the bottom that secures the shelf from sliding off the bracket. Do the same test with it pulling the load in the same orientation that it would be mounted. In other words the same way you did it but turn the bracket upside down to match the test.

@mike_abramyan 5 лет назад

I was hoping to make a small floating desk for my keyboard and mouse to rest on (and my elbows or whatever when I’m using it). If my wall has studs, how deep of a desk do you think I could use with brackets like these? Could I do 18-20 inches, if I use a wood like oak that won’t break under the pressure?

@GosforthHandyman 5 лет назад

Not a chance m'fraid - the bending of the poles would do your head in. They're strong but wouldn't handle forces like that. 👍

@DK-mr4ll 4 года назад

I had similar plans but after some research I decided to go for a wall mounted style (brackets on both ends, drilled and fixed into studs with lag bolts). I envisage the depth of my desk will be quite narrow (no more than 40cm from the wall to the edge of the desk), so I'm thinking it'll be fine. But, yeah, I really wanted a floating desk too, lol, but I think they work better when there's a supporting wall (or two) into which the desktop is situated.

@donaldasayers 5 лет назад

The bracket might not be very torsionally rigid, in which case the worst case scenario is with the load all over one bracket. If it is torsionally rigid, (is it a box section or just a strip?) Then it doesn't matter at all where the load is side to side or whether it is a distributed load or a point loading.

@mjb12141963 4 года назад

You can't anchor any kind of shelf into drywall and expect it to hold very much weight. Those anchors are called molly bolts. Attach the brackets to the wall studs.

@animationcreations42 5 лет назад

Maybe an idea for a future Test Tuesday would be retesting this using 9.5mm plasterboard instead of the 12.5mm as I think the anchors might just rip straight through. When we were moving the floating shelves I had up, one of the heads stripped on the anchor and it was a right carry on trying to get the shelf off the wall. In the end I got sick and just put all my weight on the shelf and it just tore through the board, but I'm sure that has something to do with Barratts using the worst quality plasterboard imaginable!

@GosforthHandyman 5 лет назад

12.5mm is pretty standard these days but yes 9.5mm would defo give lower results 👍

@borasumer 2 года назад

The problem with your test is that you apply the force on the very tip of the brackets pipes. So the CG of the items mostly be in the middle of them. So the 15kg you apply there should be multiplied by the distance between the point you apply the force and the wall. I would slide the board you attached to the bracket all the way touching the wall. That could yield more realistic results. Incredible effort though. Respect and thank you.

@petemc5070 9 месяцев назад

The rig set up looks clever, but I'm usure why you attached the chain where you did, maybe 25 cm away from the plasterboard wall? I'd have thought the extra leverage from putting all the pull load out there would be huge and not a fair reflection of heavy objects placed midway on a shelf.

@RadioImmunoAssay2 5 лет назад

So suspenseful! Thank you for this😄 What did you mean exactly by the heavier the shelf the more it can carry & vice versa?

@GosforthHandyman 5 лет назад

@RadioImmunoAssay2 5 лет назад

1:30 I think you just meant it's less likely a thick shelf will bend in the middle verses a thin one. I'm trying to figure out how much weight my ekby jarpen can hold. Was hoping to screw it into studs on both sides, but don't really trust my stud finder. Might have to cut the shelf down to 24", which I don't want to do. Or use molly bolts on one side & a stud on the other 🤔

@1210milky1 7 месяцев назад

@@Cassandra_Johnson ah, that's the opposite for me, I've never had to mount anything to a stud wall. The problem I have is the plasterboard is glued to the wall and unfortunately the blobs of glue have stopped the plasterboard being in contact with the wall itself. This means there is a gap and you risk crushing the plasterboard in when nipping up a screw or bolt. The other issue is that I'm almost certain that some of my walls are breeze block behind the plasterboard. Thats what I'm assuming anyway, as the material seems very soft when drilling sometimes. I do wonder if its substantial for Rawlplugs™️

@travisthechimp7857 5 лет назад

Save some money and buy some 3/4 wide metal L shaped shelf brackets the non tapered type that sometimes have a brace / welded on a diagonal. 1) Cut a ledger board to the correct L/D/H 2) Mount the ledger board onto the wall at desired height screwing it into the studs. 3) Mount a shelf bracket in a horizonal orientation (sideways) onto and flush with the top of the ledger board with the brackets near or at each end. 4) Depending on how wide the span is you can add additional L brackets if needed. 5) slide the open core shelf over the entire assembly ledger included and screw/nail into the wood of the ledger from the top side of the shelf. BTW Flat (strap) steel bent in an L shape is much stronger when mounted sideways then steel tubing is, it also cost less ( about $3.00 per L) and is more versatile when making/sizing your own open core floating shelves.

@GosforthHandyman 5 лет назад

@@GosforthHandyman Hahaha! You may be correct! I picked up 12L brackets for the floating shelves I'm fabricating for a client and the L brackets alone cost me $41.00 bucks and some change.

@markwhalebone751 5 лет назад

Nice test. I put a couple of those ikea shelves up last week into cinder block walls but used all ten holes on each bracket for screws and rawlplugs, I have four to put up on plasterboard walls soon and I am happy that they should take about 10 kg each max but would using all ten bracket holes for fixings actually weaken the plasterboard ?

@jakefallon2335 5 лет назад

They probably will if the holes are close together. Best to stagger the fixings. Andy! There's a followup for you. Close hole fixings, does it strength, weaken or make no difference? :o)

@markwhalebone751 5 лет назад

My thoughts too Steve.

@GosforthHandyman 5 лет назад

I would suspect the hole pattern shown by IKEA is the optimal route (2 at the top over each 'bar' and one on the bottom row in the middle). Is there drywall over the cinder block or bare block? 👍

@lourak613 2 года назад

It's very easy to modify this shelf by simply drilling holds in the steel strip at the location of the studs.

@robthewaywardwoodworker9956 5 лет назад

I put up 4 of the shelves in my office and used a 3/4" plywood panel for backing. I was surprised how little the shelves took before they started to sag. I assume it's the thin metal bracket that is starting to bend. It's not failing but it looks off kilter if it's loaded up too much. I wonder how differently the result would be if you hadn't fastened the drywall along the bottom (to the bench). Good video. Food for thought.

@GosforthHandyman 5 лет назад

Interesting - same IKEA Lack brand? 👍

@robthewaywardwoodworker9956 5 лет назад

Yep. 3 different lengths. They seem to sag along their length, not like in the middle or that. I imagine they stop at a certain point and just stay static there, but the look of shelves sloping down from the wall is disconcerting, if not unsightly. So I just don't overload them and I'll live with it until I replace them.

@bighands69 5 лет назад

Force is usually applied in term of surface area. So smaller areas will end up with more focus in terms of force. So that actually means the overall strength of the plasterboard is going to be tested. The same also applies to metal to great a surface area can warp over all and too small an area can cause fractures in a more specific point. Like getting a 20 foot length of wood and making a person walk out to the end to it starts to sag or putting 20 tons of pressure in one screw fitting.

@Christa-tl8jb 3 года назад

Any tips on how I can do this better?

@GosforthHandyman 5 лет назад

Thanks Andy that is exactly the video I have been looking for. What brand of snap-wedges are you using and do you have a link for them?

Mine always sag under the weight of the shelf (unloaded) and I need to pack the bracket at the bottom to angle it up.

@AnthonyJRobotics 2 года назад

This is a nice test, but you need to minus the weight of the shelf if you are testing it upside down, although it is probably not much.

It is interesting to test but the worst case would be when all the load is at one bracket. Failure is best established by looking at the displacement against load. You would see a change in the rate of displacement against load. This would be the point that when the load is removed the shelf does not return to its original unloaded position. This is most likely what IKEA refer to as failure. I agree stick to the manufacturers guidelines.

@love2vintage 5 лет назад

So would it be ok on concrete ? And would I be ok to use the cross bar brackets for heavy loads Please?

@GosforthHandyman 5 лет назад

Should be fine on concrete. These bars are pretty strong if they get a good fixing. 👍

@MrCOUNTYCORK 5 лет назад

For sure, use good plugs on a concrete block wall, for sure it will hold nearly anything you put on the shelves, i would never put a shelf on a plasterboard wall unless you can find the timber behind the plasterboard sheets to screw into

@gmo4250 5 лет назад

As you said, your weight is right at the edge, worst case. An equally distributed weight could probably double that before it breaks. I am pretty lucky in my place, most of the plasterboard is double thickness, so I can hang anything on mine.

@kingsaf90 4 года назад

Hi , why didn't you just pattress it to provide extra strength?

@vannk73 5 лет назад

I suspect that it would have failed faster if your anchors were situated at the center point between the studs rather than just a few inches away. And worse yet I think if your shelf was mounted entirely within the pocket between 2 studs (not straddling).

@GosforthHandyman 5 лет назад

If I remember rightly, if I went for centre point on any of the holes I ended up hitting a stud on other holes, so swings & roundabouts. 👍

@ramyibrahim10 3 года назад

should have put a level on the board and checked along the way. the plaster board will fail at ~25kg but the shelf will start slanting before then. at what weight would it have started slanting would have been a good question to answer.

I'm a diy noob and I've bought some Lack shelves but I've discovered the walls I'm installing on are plasterboard about 3-4 inches in and then concrete/highdensity material, and no studs that I can find with my detector. All I've got are 6x30 Duopower plugs, would it be better to try to drill into concrete and shove two plugs in, or would it be fine just in the plasterboard with the shelves fixed to the wall with all 32 of the holes used on the mounting brackets? Not gonna be using them to hold anything super heavy, mainly plastic figurines and light books, maybe a fan, stuff like that, they'll probably go over 5kg but I doubt I'll be holding 20kg with them but they are above my bed and I'm slightly worried they'll fall on my head in my sleep one day xD

Sounds like dot & dab - see my vid about attaching to dot & dab. 👍👊

@danstheman33 4 года назад

Maybe I missed it, but how thick is the drywall? 1/2" or 5/8" ?

@danstheman33 4 года назад

Never mind I just saw it on the website, it's 12.5mm = 1/2". Which is good to know, 5/8" (as is very common commercial / apartment buildings in New York at least) should be somewhat stronger

@GosforthHandyman 4 года назад

12.5mm 👍

@michaelpast19 2 года назад

I have these in my room and I use drywall anchor and it’s supporting just fine and I have my speakers and Xbox and PlayStation and laptop and printer and hair products and shower products and face products and trimmer for my beard and much more and it’s just fine without any problems just use dry wall anchors for every hole where the screws go in and it will be fine

@rimmersbryggeri 5 лет назад

I think If there were actually studs in the test rig it could take more even if the fittings didn go into them. I'd like to seethe same test donewith studs at CC45 spacing which would be normal with a 900 wide plaster board. Maybe 1200 is the normal width though then it could be cc 40 in a modern house and cc 60 in an old one.

@GosforthHandyman 5 лет назад

There are studs 👍

@Pahpahzohteh 4 года назад

I agree with @rimmersbryggeri, there are no studs behind the drywall. As seen in 15:15. I too would like to see this experiment done again with studs behind the drywall just as a real life scenario. In this Scenario there are no studs supporting the drywall.

@chrise202 5 лет назад

Wouldn't it be better to install the fixings diagonally?

@movax20h 5 лет назад

You can see at 6:20, at 6kg, the bracket and plugs are already giving. They are not flexing elastically, they are actually deforming permanently and moving inside holes. Otherwise the value would set still. But it is slowly going down. Also it is important to note that you are not applying this force uniformly across the entire shelf, but instead at the edge of the board. The distance between point you apply up force to wall is extremally important. And should be presented in torque units instead. Much better way to asses this shelf as is (IKEA Lack), is to apply your up force in the middle between wall and front edge of the shelve. Really it is important. I could break this shelve with 10g of force, if I put the load 10m away. You also need to compensate for the weight of your solid wood you used in the test.

@GosforthHandyman 5 лет назад

It's the wall giving, not the bracket or plugs. The value going slowly down is often the measuring equipment 'settling' and if you leave it long enough it goes static - however eventually the plasterboard just gives way. The force is at the front edge to simulate worst case scenario for this type of shelf. 👍

@movax20h 5 лет назад

Fair enough. Not fully scientific, and not to be compared with values of the manufacturer or other types, but still useful.

@funtomm 5 лет назад

I don't know, I kinda think it would be completely different with the actual shelf installed on the bracket. You say it yourself at the beginning of the vid: "the thicker the shelf, the more load it will take", meaning, that the shelf is higher than the bracket, giving it an extra support thus enabling it to take more load...

@GosforthHandyman 5 лет назад

Don't think it would make much difference. 👍

@charlesmcmasters 5 лет назад

great test, but I'd like to point out that I have never seen the heavier duty drywall anchors included in a shelf kit. they always seem to be the cheapest plastic anchors you can find. Then again, I also have never bought an Ikea shelf, so maybe they come with it. As you have pointed out, just a bad idea unless you are going into a stud

@GosforthHandyman 5 лет назад

IKEA don't supply any fittings - there's just too many variations for different types of walls etc. 👍🛠

@ianthompson9058 4 года назад

I imagine if it was plastered it would help you a little bit but how much I have no idea

@negotiableaffections 5 лет назад

Struggled with dry wall -itis since moving in1977. Fascinating test. But I'm curious about those screw fixings. Interesting to see them in place [usual hidden in the wall] - but were they as tight as you could make them or should they fold completely flat against the inside of the plasterboard?

@xsbxsbxsb 5 лет назад

Andy's technique is correct: www.duebel-shop.at/images/product_images/popup_images/1701_1.jpg

@GosforthHandyman 5 лет назад

Yes, I think the legs form a triangle and hence the strength. 👍

@noodlegawd 2 года назад

It would be great if they'd put a bunch more holes in the the mounting bracket so you're more likely to be able to screw into a stud, and still line it up where you want it. I guess you could drill through the metal, but why make it such a pain in the ass?

@rzholland 5 лет назад

The palsterboard might have lasted longer if the were some studs behind it [not necessarily] at fixing points

@GosforthHandyman 5 лет назад

There are. 👍

@film_magician Год назад

It cam hold 30 KG just drilling into dry wall, no studs? that's crazy wow

@SirBenJamin_ 5 лет назад

Right Mr Ant, or Dec, whichever one you are. I tried this on my IKEA shelf with 15KG, because you said it can handle 25KG, AND IT PULLED ALL MY PLASTERBOARD DOWN! ..I'LL BE SENDING YOU THE BILL!

@GosforthHandyman 5 лет назад

Yes, don't put Ant OR Dec on a floating shelf. 👍👍

@lynnmonahan692 3 года назад

So is the bottom line NOT to put a TV on this shelf?

@NicksStuff 3 года назад

I'm not sure that's the absolute worst case scenario: wouldn't be worse if the load was applied on only one metal post?

@rhymequick Год назад

No. He's right. A point load at the center would be the worst case scenario. That is where you would have the longest lever arm for either of the posts.
