daft question but can't find a answer

[reeves1985]

Been searching for a answer to this all day but have come up short

Being a plasterer but never really delved into the tiling world but in the process of re doing my own bathroom I have always wondered what the difference is between the tanking tape used with liquid applied tanking systems and the fibre scrum tape that us plasterers use?

Is there a difference and if so can someone explain what the differences are

It may be a daft question and have a really stupid answer but I guess if you don't ask you never find out

 

[nybor62]

there are different types tanking tape, mapei as a rubber backing that seals the corners before tanking , the norcross one is like a heavy duty toilet roll , but seals the corners once painted with the tanking , not sure if the tape you are on about will paint over enough to create a seal. but i know were ya coming from

Oh and the op should have read scrim tape not scrum doh!

Yeah it just seems silly to use something that costs if I can use something I already have

My perceived idea was to basically use the scrim tape bedded in with either drylining joint cement or waterproof addy then use the tanking liquid to tank the wall

As the jointing compound covers the scrim which will in turn reinforced the joints then the tanking waterproofs the whole wall

As you can tell because of my trade and having discounts it will essentially be tanked platerboard (I know some people's opinions differ on this ) but that's my plan ish

Not sure what guarantee the liquid waterproofing products give but when yours fails I wouldn't give them a ring - save some more cash!

 

[reeves1985]

I agree and fair point
The point I'm asking or trying to find out is

A properly taped and jointed wall will correct tapes and products should in effect become a single solid wall which theoretically can then be tanked using the tanking paint?
I affect just like tanking a skimmed wall?

I'm not saying I'm right I'm just trying to be educated by you fellas and ask what some may see as daft questions just like when people ask me if they can skim a wall with filler because it's cheaper for them lol

In addition to my op I am also open to the option of using matting like homelux

My install is basically a shower above bath Fed from a combi so not a great area to cover
I know I'm diverging away from my op but just filling in the background info

Some say there is no daft questions and this is no daft question (that's reserved for another member).
I'd use scrim for a jointing tape on boards with tile adhesive but only use the proprietary tape recommended for tanking, no other reason than for guarantee - which they would still no doubt decline. But by taking stage photos and keeping notes you are protecting yourself.
The best bit of the membrane type of tanking is any cracking/movement happens behind. So as long as the joins are taped that's job done - hopefully.
Good luck.

Yes I must agree I do like that idea although trying to find it at a decent price is another matter entirely

Ardex WPC comes with scrim tape doesn't it?

 

[White Room]

The only liquid tanking I use is the BalWP1 and rather use there tape for the angles I go to Halfords and buy there fine body repair glass fibre in a sheet, exactly the same material as Bal's...you get a m2 square for about £4, cut into 75mm strips and works fine.

Ardex WPC comes with scrim tape doesn't it?

It does look like it does from what I can find out on the net

 

[Rookery]

Yes the Ardex WPC comes with tape as does the BAL tanking kit. My own preference is the Mapei Aquadefence tanking liquid and their tape. I find the Mapei tape easier to use and it has a rubberised centre strip giving me more confidence as to its waterproofing properties.

 

[judge]

The Ardex kit does come with its own tape.Its a good price at ctd if youve got an account too

 

[reeves1985]

I have just requested a account
I don't have a local branch but do pass a branch in Stockport (Denton) 3 times a week so that could work out well if account is approved

 

[Stef]

I'm the same as Rookery, I use aquadefence & I'm sure it's still on a deal at ScrewFix.
I buy a 15m roll of Weber tape from CTD & it's the exact same as the Mapei tape with the rubber centre..

Tried a few different types of tanking system before taking the new tilemaster tanking kit into stock, we had previously sold the weber rubber tape. i find that the TM reinforced (and it is reinforced, it is actually quite flexible) tape sits better into the corners than the rubber type of tape.

Personal choice i guess. But i wouldnt say the TM tape was normal plasterers scrim tape.

Thanks fellas food for thought
I like to take my time but the Mrs wants it finished yesterday so need to get a wriggle on with it

 

[peteablard]

The last couple of Ardex kits I've had didn't have any tape in them, not sure if they've stopped supplying it or they were from a Friday afternoon batch!

 

[The D]

Ardex is my choice of tanking but i do sometimes use the rubberised self adhesive tape in conjunction with the WPC just for belt and braces.

Have two ardex kits in the garage. Both have the fibreglass scrim tape. I must admit it seems exactly like plasterers self adhesive scrim tape.

 

[White Room]

The scrim is good for any holes that maybe in the walls, fix scrim and mix the Ardex a little bit thicker so it dos'nt push through the scrim and leave to dry.
