Chipboard Flooring, How to Lay P5 Tongue and Groove chipboard flooring 

I did a carpentery apprenticeship when I left school 14 years ago. I ended up leaving it and going down a different route. Ive always wanted to get back to carpentery. Over the last few months I've been watching your channel and it's inspired me to get back to it.2 months ago I made the leap and have been working back in the trade and I haven't been happier in a long time.

If you could maybe post these before I do my jobs, then I stand half a chance of getting it right! Great video 👍🏼👍🏼

You forgot to fill under the floor with rubble and chocolate bar wrappers like my builders do.

Super video once again Robin. So inspiring to see the way you work. Cheers.

The most amazing thing was how you (and your assistant) both managed to avoid treading on the glue lines before it had hardened. Well done.

Very nice to see such dedication and precision .

I’m a experienced joiner with a love and passion for the job knowing about a lot what your talking about but still picking up little tips is great, and seeing someone else’s ways etc really enjoy every video always watch as soon as they ping up. Hopefully people get to put these to good practise ! Keep it up 👍

What A lovely view you've got 👏👏👍

Great video , chipboard has come a long way 🍀🇮🇪👍☺️

You love that word, undulations, great job as usual. Keep up the great content, oh and undulations. Chris

Awesome work as ever Robin! I find watching your videos a bit like learning maths at school. Makes complete sense when the expert does it and talks you through the steps, and you can follow the completely sensible logic and think "great, I've learnt that". But if you asked me to do it on my own 2 days later, I'd be hopeless!!

I had to do this earlier this year after pulling up the entire upstairs floor for the plumbing and electrics to be re-done. After having to hole saw/chisel out hundreds of nails to remove the old chipboard I couldn't face putting glue on the joists, so sadly the floor now squeaks even with spax screws. The D4 glue when doing the grooves, that glue is sticky and a nightmare to get off if you accidentally step in it or leave tools when it comes through. The glue on my spirit level is there till the end of time I think! A big thank you for all the videos, tips and advice both yourself and Roger show us. They are a great help and have given me the confidence to try many things I otherwise may not have done. I may not always get things right, but I'm learning and enjoying it along the way.

Thank you robin ur very insightful 👍 im a dab hand at most things but u help

grate job robin

Good video Robin 🤙

Propper job!👏👏

Cracking video Robin, that glue I agree is a complete nightmare, nice clean work wouldn’t of expected anything else bud top class workmanship have a awesome week all the best Tony 👍

Great job!

great video again

One other tip for those that have not installed before, on a long rung before fixing them down line up the front edge with a string line or snap a chalk line. Don't get the first ones right the sequential ones won't go together leaving gaps. Agh you have just now mentioned this in the video Roger 👍

Good job Boss!!

Thank you!

When starting first run I like to snap a line then screw a perfectly straight piece of 4x2 or 3x2 down. Then it’s just a case of putting boards in pulling them back to the straight edge timbers. I find it easier than trying to wink down a chalk line.

Great video, many thanks Robin 👍👍👍. I know now why all my chipboard floors are squeeky 🐁 🐁.

Modern equivalent of the old Weyroc flooring with fancy glue and less fixings. We use pretty much the same in Oz without the fancy expanding glue. Laid one last year 280 sq metres one floor. Construction adhesive and coil nail ringshanks. Have used the foaming glue on " oily " wood a couple of times and like you say days to wear off.

Thanks to you i just spent $3000 Aust. on new Hikoki tools. And i love all of them Thanks.

i can see you genuinely enjoy your trade from the pace you keep at work. i bet you wish you could clone yourself.

Perfect timing. Just about to redo the floorboards in my house

Superb timing! I'm about to replace floorboards with this very material in my bedroom. I appreciate this isn't what the subject of your video was about but I was curious why there was a gap left between the pir and the chipboard? Not questioning here just want to make sure I do things correctly! Cheers again for another great upload.

Robin... new boot are on the cards I hope ? safety first my man...💙👊😎

Love your videos mate - learn so much from them...! At around 40 seconds in, is that a skiing gondela cabin behind you?! 🤣

Great video Robin. It must be great to have a floor which doesn't squeak . I live in a house which was built around 1985 and the upstairs floor squeaks like crazy. Interestingly, we were re-fitting the kitchen and I noticed that on the underside of all of the boards it said all joints must be glued... needless to say they weren't! So glue was recommended even 35 years ago, although I don't think we had the same polymer adhesives back then?

As I've got 60 sheets of P5 being delivered tomorrow your video was great Robin. Now I know the advantages of using glue rather than screws and that's what I will use. Have you done a video on repairing chipboard flooring for plumbers and electricians who have to cut out chunks out of existing chipboard floors if they have to access the voids for running new wiring and pipes etc. If there is a good and neat way you could suggest that would be great. Thanks.

Great video. As a plumbing and heating engineer this stuff is the bane of my life when I need to access pipes etc under floors especially in the new builds. Love to see a tips video on lifting it or the best way to baton it back down 👌🏻

This has got me thinking about something that's never occurred to me. You need a gap between your boards and walls for expansion, Is this the case between the top tread of a staircase resting on a trimmer and the caberdeck boards upstairs?

I always use 75mm ring nails, I never worry about a join on a joist, especially if it’s 400 centres!

We just use a length of timber as a block and a sledge hammer on our timber frame jobs and does the trick!

Hi Robin. Another great video. Do you seal in the underside of the PIR or is it open to the void under the building?

Great tips and workmanship as usual. What was that Illbruck foam product that you were referring to at the end?

Interesting product(I haven't seen this in Canada), can you nail hardwood flooring to this? Thanks for all the informative videos you put out.

Any reason for not boarding it all before the stud work?

Great vid as always 👍 Wanted to ask your opinion, we having a new floor/chamber put in for the first floor which Is part of a dormer extension. Which is better floorboards or OSB Boards???

Thanks for all your great videos, really leaning so much. Do you have to nail of screw the whole area or is it just the glue that hold them.?

Hi Robin I would have liked to see some videos of you building that structure, I see you have 4 studs in some places etc, really interested in the build if you can, I know it’s time consuming and not always practical. Question for you, me and my friend who is a carpenter replaced a floor in my sitting room and hall, installed 22mm t&g osb to floor joists, then installed solid 18mm flooring and we glued the t&g and secret nail it and my floor can be a bit noisy Shen walking on it, what did we do wrong? Should we have only glued the t&g and floated the floor or Maybe the osb hasn’t got enough screws in it. Hey impossible to say without looking at the floor but what do you think? Also laid a 5mm floor underlay too? Any feedback much appreciated Robin 👌🔨🔧

Did we run out of gapotape Robin? lol. Great video as always mate.

How did you find the new hikoki jigsaw Robin

Hi robin what ear defenders are they? Are they the dewalt dab radio ones ?

Do you glue it down to the joists in a bathroom? What if you need to lift the boards at a later date?

Have you seen the flooring adhesive they use in the USA, purple and comes in gun grade foam, it looks easy to use. I remember a few years back when egger recommended a mastic type adhesive for the joists that was so thick you had to battle to get the boards tight together, just about doubled installation time

Is the air gap between pir and caberdek vented? Always thought it was full fill and gaps foamed in(minimal trapped air).

Robin, looking to replace a creeky and very cold subfloor in our extension that was done 10 years ago before having overlay wet underfloor heating fitted. I believe it's just on standard OSB at the moment. Would this product be suitable for the overlay UFH to go on and then to put the self levelling screed down over the UFH?

Agh just remembered another tip, we didn't nail the row of fixings in the previous board so that the next one would fit together easier. Any one know the standard for how many fixings are required on edge and infield? Cheers

Great Video and thanks for the tips. How many screws do you put in per sheet? Sorry if you mentioned it i might of missed it.

Just doing some of this work now. Would you consider for the on top of the joists only, a glue like multi-fix? one of the new polymer adhesives. I'm thinking about it as it always stays flexible. Doesn't foam, but easier to work with and maybe acts as a bit of cushioning?

👍

rewatching again ... now it makes me miss these days when you didn't have the best microphone ... HI!

00:29 is that a cable car sat in the field?

Does egger recommend support on the joints or is that just a NHBC requirement. I've fitted a very similar 22mm product and the manufacturer States you don't need to head the joints over a joist or provide additional support providing you've fitted it correctly with the correct glue.

Is there any chance that you take jobs as far away as North Devon? I’m desperate for a 8x4 mtr kitchen diner floor re boarded. Lodgings included 👍

I’ve never understood why p5 t&g requires a 10mm expansion gap around the perimeter, when it’s either screwed or glued to the joists solid. It can’t move, unlike a floating floor. Can you enlighten me?

Hey Robin, I am planning a timber lodge with the same type of construction and I am trying to get to grips with the insulation. Can you please advise why is the Celotex insulation on this build below the joist level (looks like about 25mm below) and not directly under the Egger Protect? I find all your videos a terrific source of knowledge and look forward to each one. Wells done and thanks for sharing your experience. Your advice is really appreciated.

chuffing hell, you got that up quick... show us building the walls and insulating and the roof!

Do you agree that the short t&g end needs to be nogged out? I’ve laid loads of this stuff without the ends always catching a joist and I’ve never had a problem. Thought that was the whole point of the t&g ?

Hi Robin, very tidy work. Question, would you ever glue the t&g joints on a floor like this?

Hi Robin I keep trying to see what framing hammer your using. Is it a martinez? I'm after a new hammer myself and like the look of that one..

Great video Robin. You always wear the same hearing protection, what system do you use?

Hi Robin , great vid as usual , how big is the room and did they need PP?

Hi Robin, a couple of questions. The PIR is not flush with the top of the joists. Is there a reason for the 10mm ish gap. You didn’t pre drill and countersink boards for the screws, is it for time saving or is there on issues not drilling. Last one, how many screws did you use per board, I think you said it’s not necessary to use screws all over. Cheers Ps great channel, high quality content.

Hi - I have an insulated concrete base on which I want to build a shed frame. Can I secure the egger directly onto the base and build the shed on top?

Use gaffer tape to make a ‘collar’ around the top of the bottle it stops the glue running back down and onto your hands 👍🏻

Hi Robin , thanks for sharing Why do u hold the jigsaw upside down ?

Robin clevett van tour ?

Interesting Podcast ...1) Laid a chipboard floor many moons ago think it was "V1313" if I remember the code correctly (Water Resistant / Water Proof ) this was on first floor of Timber Frame House. The second floor sat on top of same floor. It pissed down with rain for 42 Days (6 weeks) . My thoughts this floor is no good after 6 weeks of rain even bored holes to let the water through it was that bad . Sent away a sample of chipboard floor from each room to see if we would have to pull up same floor. Low and behold the Chipboard passed with flying colors. Totally Surprised me thought the floor was gone.. After that never looked back at waterproof chipboard floors. (The non water proof now that is like Weetabix and crap). 2) Interesting about damage to "Tongue" of chipboard and I see Robin lays floor with "Tongue" out.. I have never laid a chipboard floor this way I go the other way far less damage when bashing flat side of chipboard with "safe wood" I have laid more chipboard floors than I care to remember . "One man's meat is another man's poison" as they say or whatever works. 3) No Vapor Barrier in floor ? (Certain PIR manufactures recommend this and show diagrams polyethylene slip sheet in place )

Great video , never seen those little clips to hold the insulation board , would you be able to share a link ? Or point me in the right direction? Cheers

Are you not supposed to nail them? I see you used a few fixings . I nail these down as well as the glue and also the glue is great to use on skirting boards it keeps it tight to the wall. Great video

Who makes the gap filling foam you mentioned? The transcript rendered it as ILLBROOK? "so this is a good time to go around ill 15:16 brook do a really nice one 15:18 which is always compressible so it's not 15:21 like a solid foam is going to go in 15:22 there" THX

Would that glue be good for squeaky chipboard flooring? I have the spax already just need a good glue. Would I need to wet the joints before applying? Keep up the good work.

What is the height of this building.. from floor to pitch exterior preferably much appreciated... in meters

the gap you have left on your insulation in the floor and the wall, some do and some dont, can i ask why your choice is to have the gap please?

Another great video, please keep them coming your videos and the ones on Skill Builder have helped me as a DIYer massively. Ive noticed on your last couple of videos you have been using your jigsaw from the bottom upwards when doing small cutouts, Do you find this more accurate, comfortable or have we all being doing it incorrectly for years, Thanks

Left the 'foam' adhesive? No clean up?

Well💖 😊👆🏼🎈

If you were fitting an engineered wood floor, the first two rows would be glued together to form a straight line. Why would you not do that with T&G chipboard? Also why not nail the edge boards? The glue is powerful stuff & nails are fast.

Why did you use the jigsaw upside down?

How is the VOC off gassing

The fella I was working with as an apprentice used to like going round after the installation was complete and any slight gaps he would put pva glue in the joints and sawdust. Always wondered if this was worth it or not, any input?

Can't believe they still you by 2by 8 sheets in england would you not get more done using 8 by 4 sheets

Hi Robin, what's the reason for putting the deck down after all the frames are up? We get the floor down first and put walls on top so you have a working platform and it's far less work to put down. Love your videos by the way

Could you nail these boards?

What brand jigsaw is that please?

Hi Robin been watching your videos for quiet sometime now as i am a developer/contractor,i wanted to maybe get a price from you as i got a job coming up in goldaming gu8 Surrey ? let me know if you would be interested,the job is a new build house which i would need the roof 1st fix done.Awaiting your reply.

I really don’t like this method. I’ve used it on NHBC builds and I find it very messy, and still had problems with squeaky boards. For my own jobs I use pva in the joints and screw every board with floortite screws. It’s fast, neat and never ever get any squeaks or other problems. Can’t beat screws for holding down boards! I also use a tapping block or flooring bar saves mullering the edges with a timber off cut.

2:09 A little itchy 😂

That Hikoki Jigsaw is driving me mad .You try and buy one.

I’d rather see screw fixings than glue; at least you’ve got some chance of getting the boards up when the house owner inevitably decides they want a new bathroom. The shower waste needs to move, they don’t want the basin on that wall any more and the WC’s in the wrong place. End result: a whole load of saw cuts to get access to waste and supply pipes. Sometimes I swear it’d be easier to take the ceiling off below..

Hi Robin. How much is your assistant paying you for the privilege of working with you?

"you really need gloves". Doesn't wear gloves. Pro level.

Why are chipboard flooring so popular nowadays? I would still prefer the timber floorboards

As a handyman jobs can be easy as floor never fitted down no fixings at all or you come to the new way and your day just turned to pap. I love you're vids but belt and braces is your middle name . Even your door trims can never be removed . Replacement only nailed glue and adhesive .

I was going to ask you a question but you never seem to bother in answering them!
