Ditra Matting Adhesive

[brundlefly]

Iv'e never really been a fan of tiling/sticking directly to chipboard.....do you think either of those will work well on chipboard kev..?...

ardex AF200 is a general purpose carpet adhesive similar to the old Bal F3 adhesive and will do the job, dont get any on your arms or say good bye to the hairs its a sticky adhesive that never really sets just goes like rubber

Ok Grumpy, thanks very much, i'll see what my supplier has got in stock, i'm doing the job Tuesday, and i'll take it from there.

Im not sure where your based mike, but pentagon tiles in crowborough stock ardex materials.

Cos I've only used it once and I spent quite a while trying to ensure that the dovetails were filled with addy. I found it kept rolling out so I had to go back over in different directions to get it as full as possible. Apart from that, it was easy. it looks straight forward when you see the videos, but that part caused me a little concern.

The problem with Ditra is the Dovetails as you have said takes time and adhesive.


Durabase CI has no dovetails it has a mesh surface is the same specification should fly down for you.

Showed and got a lot of interest at the T&S show, price is good tooo

Once I have used my supply of Ditra Tony, I will get some from you and give it a try.

Sorry dave didn't see this till now but yes they do work although if you can pick up a reasonable priced SPF that works as well. (Someone told me that in the beginning with Ditra Schluter reccommended Blue Star I think to fix it). They still to this day insist you don't need to use modified adhesive once its fixed down because the membrane will take care of the movement.

Morning kev...

That quote is from schluter.com...for some reason schluter.com say un-modified adhesive is fine to tile with porcelain etc to Ditra....I wasn't happy with this because we have different scenarios to tile to than the USA does....

So i contacted schluter.Uk and got a reply from steve dennis one of there senior managers....and we can use any modified adhesive if tiling with porcelain etc.....here is his reply....( i did post this a while back but i will again for newer members)....


Dear David

Thank you for your recent enquiry regarding the use of Schlüter®-DITRA and it’s compatibility with cementitious adhesives.

Whilst the Installation Guide found on our American sister companies web site is generally generic, it must be observed that it is written for the North American market, therefore it quotes ASTM standards, which do vary greatly from the ones we use in Europe. In North America they use different parameters to classify adhesives, based on formulation and polymer types, also they need to take account of the various environmental conditions (temperature and humidity), throughout the continent. We recommend that all information for the UK is obtained via our own web site www.schluter.co.uk .

In Europe we use BS EN 12004 for adhesive classification, which we use ourselves in the UK. Cement based adhesives suitable for Schlüter®-DITRA are normally classified C1 or C2 adhesives based on the tile being used.

The use of BAL products with Porcelbond has been used with Schlüter®-DITRA for many years, which are generally classified as CT2 adhesives, we will generally advise that when using a highly vitrified tile a Single Part Flexible type of adhesive is used with Schlüter®-DITRA, depending on application.

If in doubt our Technical Department is only a phone call way.

Yours sincerely

Dave,

Actually they quoted this info when I did the Schluter 1 Day course at Schluter UK. The biggest bone of contention at the time seemed to be could you go straight onto floorboards with Ditra without plying first. I rang Schluter Germany explained and they said yes as long as the boards were fixed properly and were rigid so in other words this meant fixed to BS and screwed at at least 300mm centres. Schluter UK however said in a later communication it should be plyed first. I have laid quite a lot of tiles straight onto boards and never had any comeback. I used the cheapest contact adhesive I could find out of my local Selco to fix the Ditra and always used SPF to fix. This does not mean I won't get any comeback because I only used Ditra for the first time in Dec 05 but time will tell eh!

It wasn't the sticking down of the Ditra that concerned me kev..it was just tiling onto it with porcelain/vitrified tiles and using normal setting adhesive and not poly-modified to get a good bond......but at least steve dennis sorted it out and clarified the situation......

 

[White Room]

I know one tiler of 30 years and he uses ditra on all his floor board jobs

As long as the floor is solid then yes no probs..great product....and durabase as well will do the same job.....contact wetdecs for a free sample and compare the two....you will be impressed....:yes:

 

[TilingLogistics]

I intend to try durabase on the next job family or personal job. I saw it at the KBB and was well impressed and the fact that it was a lot cheaper than Ditra was a big factor
