Just getting loads of symbols again

I can see it.

Doc - looks like a really good product that would help overcome some common hurdles. Can you tell me more about its capabilities with regards to the point:

As an anti-fracture layer for the installation of tiles on screeds without the need of respecting the expansion joints of the covering. Later in the file it says that the floor and wall covering can be installed without fraction joints - structural joints need to be respected

I probably don't know or understand the difference between fraction joints and structural joints hence the questions:

When used can i completely ignore the need to install movement joints on say a large floor area as opposed to following the standard 10 metre rule / 6-8 metre with ufh rule?

Can I bridge two substrates i.e new screed / old screed without expansion joint?

Can I bridge screed to wood without expansion joint?

Do I need to respect day work joints in a screed?

What weight will it hold if used on walls?

Thanks
Andrew

Must be just us Darren with crap putors

Nope my Imac is the mutts nuts but still only sees symbols; got the same on the workshop pc also.

I believe the difference is, a fraction joint would be in a single floor or wall area, if the area were big enough to need one. A structural joint would be where a wall meets another wall, or a floor meets a wall etc, i believe 6mm is the standard. Also where two different substrates meet ie concrete with timber. I hope this is correct

Must be just us Darren with crap putors

tried it on 2 puters now and same thing. Maybe it can only be viewed on crap puters, and ours are too good

Maybe those on super computers who can't open a pdf doc would like to engage brain and visit:
www.mapei.co.uk
Select: 'Products for Ceramic & Stone Materials
Select: 'Complementary Products'
Select: ..... yes, you guessd it............ 'Mapetex System'

Guess I'd have had a 100 sq/m of the stuff fixed by the time you lot would have read the spec

there is a catch - you'll need to open a pdf on their site as well

Adobe reader is a free download fellas, thats what you'll need to open the file.

have got the latest version

1 When used can I completley ignore the need to install movement joints on say a large area as opposed to following the standard 10M rule/6 - 8M with ufh - YES
2 Can I bridge two substrates i.e. new screed/old screed without an expansion joint - YES
3 Can I bridge screed/wood without expansion joint - YES
4 Do I need to respect day work joints in a screed - Normally cut out and repaired with Mapei Eporip or treat as 3 above
4 Weight of tiling on walls - The data sheet highlights this as a removeable method of applying tiles (showroom) where they will need to be removed and replaced with a new product line. I have never been asked to use an anti fracture membrane on walls so do not know the weight of tiling that could be supported by Mapetex. I could find out if you really need to know.

In common with all anti fracture membranes Mapetex is designed to cope with lateral movement and not any planar movement.

A further benefit of the product is its use as a protective removable membrane over "listed" flooring shoiuld it be required

Hi Doc,

Thanks for this. The capabilities that you confirm in points 1-4 change everything for me . I was probably comparing this anti fracture membrane with Ditra (which I use a lot) and I know that their product certainly does not recommend ignoring movement joints as described in points 1-4. It'll probably take a leap of faith to go against my instincts but the benefits that you confirm far outweigh the perceived risks. I assume that you guys will guarantee this product 100% provided I follow installation procedures and use Mapei products throughout. I know the spec pushs it as a 'removable' substrate' but I'm more interested in it's anti-fracture qualities. It doesn't say on the spec sheet what sort of guarantee you offer with it, in fact it states that 'in every case, the user alone is fully responsible for any consequences deriving from the use of the product' so hence my queries / apprehension. Sorry to pin you on this but if you can reassure me a little further, you'll go a long way to winning my custom and I can see a need for this on at least 50% of my work.

Point 4 - Eporip. Wasn't aware of this product. How would I use it? Would I cut out a section of the screed where old meets new and fill with Eporip. Assuming its a 75mm deep sand & cement, how wide would I need to make the gap (if at all?) or would I just fill in the visable fracture?

Point 5 - don't worry about that weight query. I thought like ditra it could be used as a waterproofing membrane but I'm on the wrong track there so query not relevant.

In common with all anti fracture membranes Mapetex is designed to cope with lateral movement and not any planar movement. . I don't know of any other anti fracture membrane that will allow me to ignore movement joints so you got something good here . Ditra certainly doesn't and I know from a recent thread on here that Durabase C1 insists that you respect movement joints as well.

And whats the RRP on a 50m x 100cm roll & 25m x 5cm strip?


Thanks,
Andrew

Eporip is a low viscosity epoxy resin used to repair day joints and cracks in screeds. The product flows into and fills them.

Prices will be available throuigh distribution

Please contact any of our ceramic tiling specialists in technical service to discuss the points raised further and hopefully we should be able to advise a good reliable, cost effective source of Mapei products
