My husband’s is a kitchen fitter but is doing our bathroom - silly man was going to user plasterboard in the shower until I showed him these videos. It’s cost a few pennies more but a drop in the ocean compared to the cost of the bathroom. Thanks Rog
I get it... and I'm using backerboards in my new wet room already. However, there are millions of bathrooms out there that don't have a problem, and were constructed way before backboards were invented. So what did they used to do to get it 'right'? Surely tiling and grouting properly is your waterproof defence. My 10 year old bathroom was done with moisture boards, then they actually plastered it before tiling. It's been fine ever since and no grout has come out and as far as I can tell - the shower is still waterproof.
"Surely tiling and grouting properly is your waterproof defence"
PROPERLY is the key word here, can you guarantee when tiling you wont miss a pin hole,?can you guarantee the glaze on the tiles is 100%? As a trades person would you guarantee these and go back a cover any repairs or issues 3year 5years etc down the line? or would it be a case of customer must of damaged the grout or glaze when cleaning with modern harsh chemicles? As there are so many reasons to how and why a properly dont job could fail, and have failed, building material has developed to help provent the damage caused by water ingress, so must so that building reg now also require them. Dont forget plasterboard also produces toxic gas Hydrogen Sulfide if it get wet and breaks down
It's needs to 100% waterproof before any tiles get layed, I think that's the point he's making and that definitely makes sense
As an installer, the taping of joints is interesting. The specific recommendation with some manufacturers of backer boards is sealing the joints with Mega strength adhesive.
Taping gives a stronger and more water tight finish and allows for movment of the building. Using adhesive alone you are relying that you get ever mm and dont miss anywhere and as you know many adhesives and sealeant can breakdown over time, with the tape you can see where you have been and you dont miss any joins and will not breakdown. Using the paint on sealent as well as the tape also allows you o get lots of additional sealent into all the nucks and crannies and allow larger gaps to be filled and covered with the tape.
What do you guys recommend for bathroom ceiling? Just plaster?
PVC ceiling panels. Never need painting, easy to keep clean, moisture resistant. www.rubberduckbathrooms.co.uk/info/reasons-why-to-install-a-pvc-ceiling
Roger, why is there no noggins in the studwork 🤔
What’s the blue paste going on around joins and pipes? Many thanks! Great vid
Tanking membrane, you use it on the joints and holes to give a 100% water tight room. There are sleeves for pipes, tape for joints and corners. If you view more of our videos we explain ever part
Hi just wanted to know what was the tanking substance you brushed on the jointing tape?
Hi,
Can i use those backers board in bathroom with wooden floor ? Do i need to use any other tanking or waterproof membrane or just waterproof backers board are enough?
Thank you
Yes you can use on a wooden floor. see ruclips.net/video/_WbWLs_boJk/видео.html for full information
@@RubberduckbathroomsCoUk Thank you
If you put these on the floor how do you get them to merge with the wooden floor in an adjacent room?
For transitioning to an adjacent room with a wooden floor, you would use a standard hard floor-to-hard floor threshold. If the adjacent room has carpet, a hard floor-to-carpet threshold would be suitable. The process is the same as transitioning between flooring surfaces or colours in any other room.
The boards here are installed on top of a ply I think? What's the best approach if the boards are going on top of concrete/screed? Does the surface need sealing/priming before using the Fix-KST?
Yes you should prime the floor for the best results, PVA mix or simular just to allow a better bond ruclips.net/video/_WbWLs_boJk/видео.html
Question please - I have an uninsulated concrete floor and wondering if it was possible to lay insulated tile backing boards with appropriate adhesive on the concrete floor and then lay tiles on top of the backing board. Your advise would be appreciated. Thank you
Yes you can, this will keep your tiles and floor warmer underfeet. the board will insullate the cold of the concrete floor away from your feet, and if you decide to also add undertile following then will be onto on the tilebacker board and under the tile and all the heat will be directed through the tile instead of down into the concrete.
I have plasterboard in my wet room shower, it was fitted in the summer, it's now has black mould and mushrooms growing in it. Needless to say, it got be ripped out.
Would this board be needed if you're using full length pvc wall panels instead of tiles?
Not required by regulations, but recomended
Can you use these boards in the following situation: solid clay brick wall and bond the boards on the wall? Do they need any mechanics fixing after that? Thanks.
When fixing to solid walls, you would need to use FIX-KST board fixing adhesive as opposed to the mechanical fixings (screws and washers). One thing to bear in mind is the integrity and load bearing capacity of the surface you are adhering the boards to.
Hi, can you use wood screws, or do you need a that doesn't rust like drywall screws
always best to use a screw which will not rust, but many wood screws are treated against rust.
Is it possible/recommended to skim over with multi-finish plaster and If so does it need to be PVA'd? My bathroom refurbishment job is only half tiled around the room and fully tiled in the area around the shower over bath.
Multifinish, NO pva needed
cn i use these with pvc cladding and silocone on to board
yes you can waterproof and tank you bathroom with these board before using PVC cladding or wall boards. However silicone wouldn't be right for adhesive, you would be better with something like Everbuild Multi Stick as it gives a better fix on concrete based boards.
We are planning to lift the current floor tiles in a ground floor kitchen and bathroom, and put this insulated tilebacker directly onto the concrete to add insulation, and raise the level in line with the rest of the house. I can see how you secured them with the adhesive and the mechanical fastenings on the floor - do you have to seal up the joins on the floor also, and if so, how would you advise? We are not putting this in any particularly wet areas, the shower is completely seperate and has it's own tray. Any advice on the suitability of this for our job much appreciated!
Adding these board under tiles or floor will indeed help with insulation and thermal properties of your home. If you are installaing this on a concrete floor then the mechanical fixings are not required (only required on wooden floors) and if the room is not a wetroom room or wet area, then you do not need to seal the joints against water ingress. These boards are also perfect for adding underfloor heating on top of if you choose to do this at the same time.
What rawl plugs do you use if you want to screw anything into the backer board? All the ones I try just end up spinning round and not gripping…
Surely these type of boards are going to compress with the weight of a wall hung toilet + user and crack the tiles, eventually,?
there shouldnt be any issue at all, all the weight of a wall hung toilet is taken by the frame and the any leaverage on the toilet pushes again the frame, the boards and tiles and fixed to the frame and shouldnt flex as the frame supports the boards where the toilet touches. We have a wallhun toilet installed in our showroom with only part covered in boards alone to show the steps on installation of a wall hung toilet and taking a room and the board is fine, it also recieved more "traffic" (people sittin on it) than a normal houshold toilet.
Hi - no insulation /wool under board ?
@@fastteddyb elements boards offer a form of insulation.
@@RubberduckbathroomsCoUk I see - thank you
What if you only want a couple of tiles around your bath but want to use this board?
not sure what you are asking here.
@RubberduckbathroomsCoUk If you're not tiling to the ceiling how is the board finished?
@@neilrafferty2097 The board itself should not need to be finished as it would typically be flush with whatever surface is above the tile. You seal the joint between the tile backer board and what surface sits above and use a tile trim to cap off the tile.
Can you dot and dab this to a block wall? Or does it have to be screwed? (Just taken our tiles off in our bathroom which has removed the existing plasterboard on dot and dab). We're tight for space as bathroom already 1700mm long where the bath will be so not sure we can batten these boards onto it. Any recommendations greatly appreciated! Love your channel and have got lots of great tips from your over the years, so thank you!
yes you can dot dab them to the wall, but you should also use a mechanical fixing to increase the weight load of the wall for the tiles.
@@RubberduckbathroomsCoUk super! Thank you so much!
Do you know if the membrane will effect the told adhesive strength?
As you are not painting the whole wall with the membrane, the added extra hold weight and stringht of the the board would over come any loss of the membrane. you will find this video helpful to explain weight of tiles and the substrait. ruclips.net/video/-aSWUYHgp7c/видео.html
@@RubberduckbathroomsCoUk Many thanks :)
I appreciate your sponsored but how does it compare to qboard basiq?
Qboard appears to be a BNQ own brand product. We have not used these product to be able to compair. The information on their site appears to be laking information regarding the weight bearing load and other information to do a side by side comparison.
You've probably done the job by now, but I noticed a massive difference in flexing between the 10mm Q boards and the 12mm Jackoboards and Elements boards.
@@stevenb007 I have done the job but they were bonded to a plastered brick wall so flex was not an issue. Thanks.
@@stevenb007 Q board is a BnQ Copy of the original. What difference do you mean? which flexy more?
Thank you for this. Can you please tell me if these boards can be chased out if on a block wall? Thanks!
yeah in the same way you can with plaster board. How ever if you pipes are chased in and left exposed, then this area isnt water proof as there is no board there. You can cover the pipes in the tanking take to waterproof over.
@Rubberduck Bathrooms Ltd Great. Thanks for taking the time to reply.
How it will cost same size buthroom to install tiles and furnitures?
Do I need to strip old plaster back to brick around my bath and shower for this to work?
No you can cover exsisting plaster and render as long at its not crumbling or already damaged by moisture and mould.
Do you have a written installation manual? I'm trying to find out exactly what thickness boards you recomment for different types of walls (stud/stone/brick etc)

The walls in my bathroom are plastered, I was going to PVA and then tile directly to the plaster. I am now considering using the recommended adhesive to install these boards to the plaster and then tile. My thinking is that it will give better waterproofing, adhesion to the tiles but most of all it will improve the flatness of the surface I am tiling to.
Would you recommend I do this please or can you foresee any problems?
Yes we would always recommend using these boards. To comply to building standards you need to waterproof / tank before tiling.
Rubberduck. I was thinking of using these board on the bottom of damp walls (rising damp) as I dont trust the injection method !. I was going to fix them and get them plastered over, what do you think?
Thanks.
Hi Stevey G, elements boards can be plastered over to leave a paintable finsih and are waterproof so you could use them to "hide" rising damp, but you are just hiding the problem. Our advice would be to try to find the cause of the damp (DMC, leak, gutters, airflow etc) and try to reduce the damp. ruclips.net/user/SkillBuilder have a number of video to help expalin damp etc which you might find helpful, you could even contact them with images for there "ask skill builder" series and ask them about elements boards for damp proofing and other options and they will give you some more good advice. In our opinion we would look into why you have damp and try to cure it with an chemincal injhection dmp and interior tanking etc then you could use these boards for an extra line of protection.
Can I put them straight on to old tiles
yes you could as long as you use the mechanical fixing to make sure you get a good hold/fix. also make sure the tiles are clear. But really you want to be removing the tiles and geting back as far as you as covering over tiles you are just hiding any water ingress thats already happened and any mould growth you have already.
Hi,
I was wondering if you could use these elements boards for the floor of a wetroom instead of a wetroom tray? Or are you supposed to use both?
Also, what was the liquid that you put down on the floor before the tiling stuff?
Thanks
you need a wetroom former for the showering area which has a waste built in and a fall to direct water towards the waste. outside the former you then waterproof with the elements boards.
@@RubberduckbathroomsCoUk qboard do various sizes.
The liquid is SBR a bonding agent. To make a floor waterproof use a tile membrane
Is all Elements board waterproof or do you need specific elements board? Can't see to find a stockist in the Worthing area.
Element Board Is The Name Given To Abacus Range Of Waterproof Boarding. We can Deliver Abacus Boards Nation Wide to Your Door
@@RubberduckbathroomsCoUk Ah OK. Can elements board be used for the ceiling? I know you can use it on the floor but can it also be used on a ceiling instead of plasterboard? If so, what would you then do to get a smooth finish?
@@TheStevenWhiting There is no reason whey you cant use them on a ceiling for extra insulation and moisture resistance. These boards can be skimmed with plaster and then could be painted with a bathroom paint, alternativly you could use some PVC ceiling boards for a smooth waterproof ceiling.
@@TheStevenWhiting yes you can use them on a ceiling, and they can be plastered over then painted with a good quality bathroom paint. A better alternative to palstering and painting would be a PVC ceiling cladding. www.rubberduckbathrooms.co.uk/ceiling-panels
Where can you get the waterproof surrounds for the taps, valves, water outlets etc?!… struggling to find them. thanks

Hi is element board same as backer board thanks
depends, backer board is a term used to describe a wide range of products. It would depend on the brand.
Abacus elements Boards are also refered to as backer boards.
Is it ok to screw these directly into a brick wall or do they require a cavity behind them? Thanks
I screwed mine directly to the brick wall without any problems.
You can screws or adhere these directly to brickwork, no cavity required.
We are renovating... would you really put this in full room or only FLOOR and the areas getting Wet? EG - Moisture resistant PB + Tile on a NON-Water exposed wall.
If you want all the benifits of these boards, ie the waterproofing and insulation value of the boards, then doing the whole room is the best option (also less dirty to cut than plasterboard), but ifif you just want to conform to build reglations etc then you only need to use these in the wetware on the wall, and on the floors of wetroom, you can then use plasterboard etc on the other walls as long as the tiles you have chosen are not heavier then the weight load of plasterboard. See here for more info on tiling weights and the building regs. ruclips.net/video/2Mi6Nl02Ae0/видео.html
This material is more expensive than ordinary gypsum board or cement board, but it is also obvious. It is light in weight, easy to cut and almost dust-free, but the point is that it is very strong, and it is the best for bathrooms.
Can I fit my shower tray on top of the elements board? Or does the tray need to be fitted first and boarded upto it
Fit the tray first then board upto the tray, this also makes the tray look alot lower profile.
Thank you
What are there revolver barrel looking washers you use with the screws to keep the board on? Thanks
Fixing Washers, Available in different sizes, with or without screws and in different pack / bulk sizes.

Hi there, I was tiling my kitchen and on the corner there's a ply boxings covering the water/heating pipes, How will I bond the subway tiles on the ply? Thank you!
Standard tile adhesive should bond to plywood without an issue, you may wish to prime the ply with a PVA primer but normal tile adhesive should bond as subway tiles are very lite weight there shouldnt be an issue. Kitchens are different to bathrooms and showerroom and building requirements are not a strict.
@@RubberduckbathroomsCoUk Thanks so much for getting back!
Im not a builder, so probably using the wrong terms. Ive removed old tiles and the plastering behind the old tiles is dusty and crumbling, would i have to remove all the old plastering and take it back to the bricks before putting elements board on or can i use a pva (which would you recommend) and dot and dab and use wall screws also to keep elements board in place?
If you PVA watermix and paint over the backing plaster and allow to dry over night and see if it has helped to stop it crumbling. If its still really crubling and coming away it would be best to remove, if its stopped it crumbling then you can dot and dab and mechanically fix elements boards over it. If you can get the screw through the Elements board, throught the cumbling backing plaster and into the solid wall, then the boards will be solid.
Where can you get the bits of material for around the showers ?
www.rubberduckbathrooms.co.uk/abacus-wetroom-accessories?show_all=1
Can it be used on floor boards
yes, just ensure you floor boards are screwed down or nailed down tight to reduce movment.
Can I fix the elements board straight on to plastered walls that have been painted? If so how should this be done?
Yes you can go over plater boards with element board. You can fix them to the wall with KST adhesive or using the mechanical screws and washers.
@@RubberduckbathroomsCoUk thanks
@@RubberduckbathroomsCoUk
can you put the element board on top of plaster if it's already there?
I'm not an expert, but I would assume that as long as your plasterboard is in good enough condition, fixed securely and your screws that you're using to attach the tile backer board are long enough to get through to the studs or whatever the plasterboard is attached to then you should be fine. After all, it's the tile backer board and the tape/paint that gives it it's waterproof properties. I'm doing one right now and I'm removing the plasterboard first and replacing it with that stuff.
Yes you can. 6mm thick boards are often use over plaser boards to add the waterproof protection without adding to much extra thickness to wall and loos of space in a room, but you can also use thicker panels for more insulation and to packout/build out walls to suite showertrays etc. You just ned to make sure the plasterboards are secure.
@@RubberduckbathroomsCoUk If you put the 6mm boards over the plasterboard, do you tank inbetween the plasterboard and tilebacker board? or do you tank ontop of the tilebacker board? or neither?
@@martinpalmer3575 the abacus boards are waterproof so dont need tanking, you do not need to tank the plaster boards before applying the abacus boards, you just need to tank the joints
Are they 300mm centres for the boards? Can’t find the info anywhere on the web, although i’m sure it is out there.
Also, i note you didn’t add noggins for the joints of the board edges!, which i expected would be required!? TIA
Most of the boards are 600mm wide, so 300mm centres are the best option.
Thats how u do a job right.
