here you go.. lets hear it lol...

[Daveshadowman]

I know its supposed to be staggers but didn't want little cuts of hardi on the boards so did it this way. View attachment 53156

There could be trouble with this in the future

 

[DHTiling]

im only guessing but looking at the pic now id say to stop a dip forming in the cross of the join mate?

It helps with contraction / expansion and now that could crack at that section.

Cross-bonding has to be done for said issues.

Little cuts ?? Just the board in half...so half the boards !

cheers dave I will make sure in the future its done correctly.

I don't follow Neale lol. if I would have moved the board on the rite up a foot and put the cut at the bottom end would that of been the rite way?

 

[Mr Tiler]

excuse the bad paint skills but would this of been ok? cheers

 

[Gazzer]

Yes....

Really??? In a round about way it could help with expansion contraction but that's not the reason for cross laying.

Ok , plz do tell us all then.

 

[DHTiling]

So CR , you are saying that cross bonding has nowt to do with creating a stronger wall/ceiling or floor and from helping to prevent stress cracks if you stacked overboarding.

Plz do enlighten us.

 

[Colour Republic]

It's for strength. Any joint is a weak spot and by cross bonding you are reducing the length of weak joints. It's the same reason you cross bond plasterboard, the same when brick laying

So like I said then , the joint can only be weaker for expansion if not cross bonded. ?

Yes or no ?

No not at all see my reply above. But it is not to do with expansion/contraction as the primary reason. You could argue that you are reducing expansion contraction of the preceeding layer by cross bonding / stitching over it, but that is not the reason you do it.

Yes it can be weaker but not the primary reason like you made it sound in your first post

You have 3 movements CR , deflection / expansion and contraction , so you have lost me.

Cross bonding can help with the 3 above but I never mentioned deflection as hardibacker does not deal with deflection , so again plz do say why. ?

 

[DHTiling]

Lol. I typed and made no sound. I gave info on the floor boarding , if it was walls then I would have advised further.

 

[Colour Republic]

You are missing the point Dave it is to add strength to the joints. I'm not going to get in an arguement with you over it.

CR, I am not after any argument. In what way does it add strength.

I just need clarification plz.

 

[Qwerty]

I was on the understanding that it added strength as the long side of one board adjoined the joint of two boards next to it, spreading the load if you like. Less stress on 3 than on 4 also?

 

[Colour Republic]

CR, I am not after any argument. In what way does it add strength.

I just need clarification plz.

Because you are shortening the length of any joints as in the next board you are stagering.

take a 300mm tile, score it 100mm from the left, score 100mm from the right and then try snapping it. now take another 300mm tile score 300mm all the way across. You know whats gonna happen and which is the stronger of the 2

 

[DHTiling]

Ok , so by shortening the length of corresponding joints , what is that combating ?

 

[Colour Republic]

Not introducing weak spots / fault lines

 

[DHTiling]

Not introducing weak spots / fault lines

Agreed.

And these are caused by what stress ?

 

[Daveshadowman]

Come on lads I think you are both trying to make the same point just wording it different at the end of the day you always cross bond the floor mr t has done will have problems later and that is his inexperience showing

Thank you Dave. Just some like to split fricken hairs.

 

[Martyn Leeds]

I guess most folk are ok with installing Hardibacker, this is Teabag's thread yeah?! I'm not gonna give any opinion on the quality, as enough has been said. Mr T, I'd change your goal from being a s/employed Tiler, to just gaining full-time employment, in whichever job is best for you. Perhaps have a longer-term goal to maybe do a bit more diy/amateur tiling over the next few years. But with a full-time job, you can look more into college/courses etc to do it right in 5yrs time or something... not 5 weeks. Kapeesh?? Lol

 

[Colour Republic]

Agreed.

deflection

 

[DHTiling]

deflection

Lol.

I give up.

 

[Colour Republic]

What be because you said Harding doesn't sort out deflection? Missing the point again Dave.

 

[DHTiling]

CR , you ain't got a clue , your replies say it all.

I missed deflection from a post that hardi does not deal with and you pick fault.

I have stated a few times there are 3 causes of stress and you say deflection. ?

What about dry lined walls , do they deflect onto block work , ffs wake up.

 

[Colour Republic]

Oh dear or dear oh dear.

no the the block wall does not deflect but the plasterboard itself does!!!

And I have got a clue????
