I run into a problem after priming so tryed to buy more primer from b&q but could only see mapia plaster primer so while there i looked on back of the container got a help tec phone number and phoned them lad very helpful and said it was the same stuff! And ok to use £10 sorted ! ! !
Hi there, I'm in the process of plastering my bathroom, it is a small one and not a wet room, so can I still "tank" my room and can I still do this process if it is freshly plastered? thank you.
How do you seal the plywood, what type of acrylic you were using? applied to edge and back face of the plywood. Can it be used with Primer G(Apply paint first then Mapei Primer G)?
NSAI Circulated a memo in Ireland in 2014 saying plywood is not a suitable substrate for Tiling on. Recommend product is magnesium board or cement board.
you want cement board for a shower cubicle, then you can use this on top otherwise if any moisture gets through it will undermine the plasterboard and fall apart from experience.
Why not fibreglass & resin the whole area? That would be 100% waterproof for decades. In fact, best to install a slight lip, and a drain in one corner to allow any water out when, eventually, the tiles leak.
Good info, I'm going to fit a bathroom for the 1st time. What type of flooring did you put down under the shower cubicle. Also on the tanking kit, does it say its ok to tank on non-plasterboard walls?
We used thick plywood for walls then screwed cement board on top, each was tanked etc. You can tank the plastboard then tile over it, just make sure it's properly done otherwise it can be costly in the long run. For the flooring we also used really thick ply, tanked, applied some adhesive for a special waterproof membrane then tiles. but we used good quality materials including adhesive etc throughout, we had a bad experience with a previous bathroom so wanted to do everything right and did not want issues as it's upstairs. I hope that helps.
Daniel Thanks for the tips. I dont want to have to get it done twice so I'll make sure its done properly. Cant really find a detailed step by step guide on how to do certain diy projects in the bathroom but I'll just have to go to numerous sources of information.
Can this be used straight on to plaster board or is it better to use a tanking membrane? Im wanting to avoid putting up backing boards if possible. Hope someone csn help
Hi there someone done my bathroom last year and it started to leck so got someone in who said the water is behind the tiles so I don't think they waterproof the walls so all the plaster boards are rotted so need my shower walls replaced
@@DanielJohnHowTo I do hope so he seem like he know what he his doing he looked at it said say it was behind the tiles and it hadn't been waterproof properly
Not “basically yes”. The answer is yes. That’s the whole point of this product. To seal the wall to prevent water that might find its way behind the tiles, through the gap to the shower tray or between two walls at a corner or even if the grout is not perfect. This saves the wall from going moulds etc. Use a powdered C2 tile adhesive. 👍
It is, but it doesn't matter too much because once it's all tiled which it was and looked very nice you would never know - it's not what it looks like now, it's the end result that matters, there has some wisdom free of charge, thanks for your comment.
This is such a bad video! You should never use Plywood as a substrate for tiles. This has even been out ruled by the British tiling association as there is too much movement in the wood and the tiles do not adhere to it meaning they will crack and come loose!
@@DanielJohnHowTo it was outlawed by British standards at the start of 2018 due to the decrease in plywood quality imported from overseas. Iv just seen however your video was posted dec 2017 so will remove the comment but you should update the video to reflex the change in standards
Daniel you had loads of creases that didn't brush out. Should be using the brush to push it right into the corner then brush to outer edges. It will work but if you were doing it like that for me I would be whinging but then I'm ocd.
I use a stiff wallpaper brush to get the tape right into the corner, being careful not to make and rips or holes in the tape as i dab it with the brush
Gyula Nagy It has been applied correctly and you never see it anyway so it does not matter, things don’t always need to be perfectly done and we are living in the real world. The bathroom never had any leaks etc which proves the tanking process was done correctly despite the aesthetics, how many bathrooms have you done ?

very good I will buy this for my bathroom, very well explained. no water getting through that
Brilliant video, really helpful. Good questions from the guy holding the camera. Thank you.
Glad it was helpful!

Nikki Powell yes you can Nikki
Thanks chaps! Good work and good down to earth explanation 👍👍👍
Thank you
@@DanielJohnHowTo do I need to tank on concrete walls.around my bath
Great video guys; Id like to see the one on the ground floor but cant find it
thanks, same process really if you want it to all last.
Can you apply this over taped and joined moisture board? Within a bath shower?
it can be used to seal it yes
How do you seal the plywood, what type of acrylic you were using? applied to edge and back face of the plywood. Can it be used with Primer G(Apply paint first then Mapei Primer G)?
We use an acrylic primer paint first with three coats and then Mapei on top - hope that helps.
Thank you.How about the back and the edges? Do they need to be seal with acrylic primer paint?
yes back and edges, let it all dry properly.
Thanks. That is very helpful.

Very helpful good man👍
Glad it helped
The instructions say that you should cut off the scrim edge. Whys that?
Can i use this without the primer?
Thanks! I am going to do this now!
Can you put this straight onto plaster board??? Thanks
you want cement board for a shower cubicle, then you can use this on top otherwise if any moisture gets through it will undermine the plasterboard and fall apart from experience.
Is the primer basically PVA water down?
it has lots of different compounds etc, pva can be used to seal against moisture then primer and paint depending what you're doing
i m from india good prodcat mapei
Can you just use the paste without the primer or is that no no.
primer for the board?
Why not fibreglass & resin the whole area? That would be 100% waterproof for decades. In fact, best to install a slight lip, and a drain in one corner to allow any water out when, eventually, the tiles leak.
Yep you could also do that, thanks for the suggestion.
Fibreglass and resin isn't as flexible. Movement in the structure could cause edges to come away and compromise the seal.
Not to mention the noxious fumes filling the house.
Does this product work on Hardiebacker board ?? Many thanks
Yes it does
can i paint this mapei stuff over aqua panel ??
Yes you can, it's designed to waterproof ot tank a wide range of substraites.
Could this be used on standard plastered plasterboard or should it be changed for moisture resistant plasterboard?
you would use cement board with stainless steel screws
Thanks for the video very helpful
Glad it helped

Not really, you want AQUAPANEL® Cement Boards made by Knauf
@@DanielJohnHowTo cheers mate, have you ever used shuluter-kerdi waterproofing
@@jakelowman5721 never heard of it, but with bathrooms it's important to do the tanking properly to avoid issues with tiles etc from experience
Hi there someone done my bathroom last year and it started to leck so got someone in who said the water is behind the tiles so I don't think they waterproof the walls so all the plaster boards are rotted so need my shower walls replaced
We had the same problem ourselves hence the video, the entire bathroom has to be re-tiled it was a nightmare.
@@DanielJohnHowTo I know someone said they can fix it for me any ? I should ask him as don't want this to happen again
@@debbiehorne7191 You want knauf aqua panel or similar, then it all tanking with Mapei but make sure they are going to do it properly.
@@DanielJohnHowTo I do hope so he seem like he know what he his doing he looked at it said say it was behind the tiles and it hadn't been waterproof properly
@@debbiehorne7191 That sounds promising.
Can you tile straight on top?
Basically yes, but use decent tile adhesive even if it costs a bit more.

Is this suitable to be use on hardie backer cement board?
Yes.
Very helpful videos!!
Glad it was helpful!
Right pair of dossers 😂
cheers guys .
thanks
Time to get anew demonstrator,
What an honor, didn't realise we had a shower waterproofing expert viewing our videos!
Can you no just get big rolls of that and do all the walls 100%
Tanking not needed imo, so long as tiles are properly fitted to ordinary pva'd plasterboard
depends how long you want the job to last for
Great stuff, thank you
Thought cowboys wore hats.
shows how much you know
Looks a bit messy 😂
It is but, leaks are worse when you've finished the job.
Couple crooks. Not supposed to slop it on, needs to be a thin layer rather than a thick layer.
Sounds like an ad for screwfix
That's one sloppy looking job. Tiler will love that

@@DanielJohnHowTo air pockets, moisture, mildew, black mould...
@@seanmacseanreinvented9306 yeah agreed, much better to have rotten soggy joists /s
It says on the tin not to use this for wetrooms
yeah this is a shower room not wetroom, so it's fine and has been.

@@doma5262to be fair that’s exactly what’s happened to my bathroom floor I did in 2010, whole lot has to come up.
Total rubbish at putting the tape on..

This guy is messy a lot - look on brush
ANNA IWONA true but it’s a job well done and you never see it anyway
Trashy application of good quality material. I would give anything like that into your hands.

Will one of you decide who's voicing over, it's like watching two alpha chimps chipping in, vying to talk. Very distracting.
wow, rude.
