Went into the Lab Today!

[Protilers]

Hello all......

I went to the Lab today and met up with Gary (gary the tiler) and Ray (ray tt).............

here is what happened!

all the best.....Happy new year!

Thanks for doing the video Lee ,it was good to see you and Brick top today

The pleasure was all mine Gary............where is "brick top" I wonder?

 

[Bubblecraft]

Great vid guys. After watching that, it's put faith in tiling direct onto ply lol














Hardibacker all the way! Happy New year guys

I suppose as well is what adhesive was used.

part two was a bit scary with Lee peering in to the camera, but on a serious note what does this represent lateral thermal expansion ? how much expansion did it take to fail ? what measurement ? nice comedy trio !!!

 

[Protilers]

I belive it was Tilemaster S1 rapid we used........and I have to say I thought it would have split much easier.......we broke two workbenches.........one is repairable......the other has gone to a better place!!!

it represents lateral movement DPF you are right.....but we need to build a bigger rig to pull them apart.....we snapped both workbenches.........its proberbly needing to involve heavy duty vices..........or bottle jacks....

hehehehehheee

we did some brain storming after we shot the video and have come up with a plan to create a jig as Lee says which should have to strength to do the test accurately and in a controlled way, we are looking to get to 3mm sepration between the ply boards as this is what some of the crack isolation mats claim they reach before failure

BUT you have to know the force !!! in a measurement of force to know it's braking point !! so you can compare it to the others !! then you will have measured results to compare :lol: otherwise it means sqiddly :hurray:

 

[Spud]

the force is irrelevant if they fail before they reach 3mm as that is the propsed standard for crack isolation matting ,we have thought of using a tension scale or even fishing line to test how much force is being applied

 

[Diamond Pool Finishers]

you have to know the the force that each one starts to break surly !!!

 

[Spud]

the test will be how wide the ply gets in mm before they fail 3mm is a pass anything less is a fail ,i was amazed at how much force it took to seperate the tile from the plywood today and when we did eventually get it to release it gave a loud crack when it broke apart it has restored my faith a bit in spf to be honest

i can honest say i aint got a clue what you all are trying to do, stretch the ply ?:smilewinkgrin:

surely it would be better doing it the other way,pushing (bending)not pulling ?
does the ply not bend/swell when drying causing the delamination ?
to stretch timber like that you will need a hell of a lot more tension than a little workbench with bits of plastic acting as the pulleys:smilewinkgrin:

i may be wrong,i aint no scientist but it just seems pointless,not being bitchy lads

The ply is not a single piece, it's 2 peices butted together and a tile bridging the gap. They are trying to see how far the ply can be pulled apart (contraction/expansion) before the tile or addy fails. This is just the first piece, the other pieces have various brands of decouplers (again two peices of ply, bridged by the decupler then a tile on top) to see what the decouplers bring to the party.
