Didn't know we could automatically add those video types. Good find too Neale.

If only they explained more about the priming etc.. not quite as easy as that..

my thoughts too Dave, because it doesn't show the 2nd coat being applied at 90degrees to the 1st coat. which is what i understood the process to be. comments please Lee/Weber. other wise perfect.

And not all anhydrite screeds need a severe sanding now either, for instance Gyvlon LL is low laitence and if kept clean, just needs priming but as we all know a floor is never kept clean , so just needs a light sand to remove surface dirt and not a laitence

 

[aph257]

good point also.

Good video all the same for guys that have never seen it done, myself included

I have a number of issues about this video.

1 It does not show the priming process fully (i.e. no second coat)
2 It does not distinguish the different types of anhydrite screeds which are available
3. It does not take any account of moisture content
4. It takes no account of the health and safety aspect of sanding floors (should really use a vaccuum attachement or slow speed rotary sander so you don't throw dust about
5. It takes no account of the various types of calcium sulphate screed available
6 It says they are self levelling screeds - they are not
7 It seems to imply that an uncoupling membrane is a requirement (Not surprising as its a Dural/Weber video so soirt of forgivable) - Uncoupling membranes are by no means a necessity
8 it does not mention underfloor heating (many of these screeds are over wet underfloor heating systems)

On the plus side its nice to see someone at least being pro active. Weber have also got a Gyspum based addy in the UK now. I am going to see some in use tomorrow so will report back on tilers comments.

Get in!

What the hell would we do without you?!

I have read my reply and feel as if I have been a little abrupt - almost harsh in my critique. I did not mean to be but am in a blunt mood today.

I have seen this video just after it was made and did bring some of these issues to Weber at the time but it was clearly too late to do anything about it. I guess to put a more pragmatic and reasonable slant on it if you follow the advice offered in the video you are unlikley to have any failures provided any underfloor heating is comissioned, the screed is dry enough and the joints are clearly defined.

It is just that this shows just one way to deal with the screeds. There are others available.

Invisible spacers i must get some of them, poor bloke looked like he was struggling with that job...

 

[Gazzer]

So sorry for putting the video on the forum.

 

[Ajax123]

Don't be sorry. It's not that bad.......and when all is said and done it is only a "sales/training" vid.

 

[Dan]

As said, don't be sorry. If it airs corrections then it's a must! I wish we had more incorrect video's and theories added to the forum so they'd get corrected, though clearly the risk is they don't get corrected.

But in this case, it did. And it doesn't matter if you had a dodgy day, I think you put everything across in the only possible way to not cause confusion.

You never know, even video's being made might end up being in more detail for the benefit of even the creators.
