AAAAAHHHHH...but Dave.....

we have noggined out our floors.......then we have installed 18mm ply over floorboards.....at 200mm centres........it is as solid as a rock!!!...
we have allowed a 5mm "expansion" between the 18mm ply boards.....that we have fillled with Silicon.......

its as solid as a rock!.........

why do I need a decoupler?............afterall...they only give a guarentee against laterall movement?........

not diggin............I have to get the car ready........nite nite!

Yes... but not all floors are prepped that way :)

its not interesting...DPF.....its a propper boring "copy and paste"...........and not interesting at all........and also.......its what you have been told.......NOT WHAT YOU KNOW!.........

nite nite
well i find it interesting Lee, it's a very interesting subject in general , nothing wrong in copy and paste,, i was not trying to pass it off as mine (like others on here have done ) and it come's from a more reliable source that three guys in a garage !! love it ....... :thumbsup:

if the guys want to re-create thermal/lateral stress , then they would be better off putting the samples in a fridge then straight into an oven surly !! pulling the sample apart is not the same IMO ..... and i'am not having a go at them just trying to make sense of there experiment .....

it was an example of thermal/lateral ... <<<<< notice the lateral word... side ways movement if i have to use laymans wording...

Anyway i was backing what the lads are doing and not saying it was wrong.... pool fool jumps in again :lol:

yes Dave sideways due to THERMAL EXPANTION /CONTRACTION not pulling only , you should have stayed admin and you could of banned me again, instead of keep trying this pathetic banter of yours (grow up man )

dpf the article you posted is interesting reading but you have to understand how the 2.5 mm deformability is reached.It is tested with a piece of string covered with adhesive suspended betwen 2 points and a weight applied if it exceeds 2.5mm its an S1 if it gets to 5mm before breaking its a S2 so how this relates to a tiling installation and the real world I am not quite sure for me I am more interested in the polymer content of the adhesive as this is what gives the bond to the back of the tile on porcelain . matting failures have cost me money so I will be testing them and will use the ones I find perform the best

I've had a rate good skin full just now so won't waffle on.

What I will say is; I've watched every video and enjoyed them.

I've also seen the work gone into a) setting the tests up and b) committing to rules and showing to us what those are.

But in my opinion, with the same amount of effort and money, you guys could probably pull off some tests that perhaps get done behind the scenes over and over again by manufacturers, as they try to better their products compared to competitors, but public ally and including many brands.

Just saying you put a lot of effort into proving not much when it comes to British standards.

Perhaps you could focus on showing people why each product gets the rating they get and why you should use a product over and above another.

As said; I've watched all your videos a lot, sometimes I've watched some 7,8,9 times.

I like them. But they're genuinely not showing people what product is best. They're more sort of showing people what you guys have found is best in the conditions you've setup. And it's not something that'd stand when it comes to British standards which is a shame as people watching the videos might assume they're endorsed in some way by the brands quoted in the videos.

And I've not seen one brand so far agree that your test is endorsed, even the sigma v rubi ones.

Again, I like them, but I think the same amount of effort, doing it the right way, would carry more weight generally.

Get a tensile machine for a start I bet they're only a few quid they're just a compressor and a measuring thing by the looks of it to me. That'd get your adhesive and coupler tests to bs.

I don't think the guys testing are taking this too serious tbh... Are you? Your not looking to re write the rule book are you? The way i see the tests are like lee says, just a bit more nuts and bolts real world 'advice' to the tiler.

that's all it is imo, we all do little tests every year. The guys are just doing things that we all think of doing so its all good.

having said that, i don't think its fair to say they are just messing around, there results are quite useful.

chill out you lot... Just chill :)

I was thinking today about the test we have done being unscientific and being asked to use a tensometer to measure the force being applied to the pieces of plywood when it dawned on me than the forces may be worked out using mechanical formula that you learn in physics at school, the forces applied to a screw thread can be worked out with a formula called "mechanical advantage" and the force applied to the turning handle can be worked out using the "moment of force" calculation this is measured in newton metres ,I am going to do some research into this over the next few days and dig out my old o level physics text book to see if I can work out using these simple formula the forces being applied to the ply wood through the screw threads of the jig we will be making
