tiling on plywood: how to deal with the 3mm gap: plywood joints

[peteablard]

i personally think we are all mad on here.
we give advice to people that puts us out of work...i can just imagine sitting infront of alan sugar and saying,,err ive got a business, its called tiling and i tell people how to do it on a forum and then they go off and do it??

this recessions got me thinking? how about the rest of you?

A very valid point Ed. for the last 4 years nearly all my work has been commercial, I've got some great contacts and the work has kept coming in. At the moment I am about to start to try and break back into the local domestic market and hopefully split my time between the 2. I must admit if there was a local tiler new to the trade asking question it would make me think twice about helping....... But knowing me I'd still help!!!

i love helping people too pete, i really do. id give you my last pound if you needed it more than me.
maybe my comments were selfish?

ok, mirjam
if its just 25mm ply over stable joists, then id leave the gaps and simply overboard the ply with a tile backerboards glued and screwed with the same 2-3mm gaps around the boards (taped & filled with spf adhesive) and then leave a 5mm perimeter expansion gap around the edge of the floor of the room...theres your suitable surface on which to tile...oh and you will have saved a bit of money seeing that cash is a bit tight being a student and all ;0)

not at all pal, I've seen a few posts saying similar things. I like the thought of helping someone through a DIY project knowing that even if the finish wasn't quite right they'd be really pleased with what they'd achieved. It's the chancers that think they can make a few quid tiling "because it's easy" then need to be talked through every step of the job. I have real admiration for the people who come on here offering free help to anyone that will help teach them a few things, the ones that genuinely want to learn the trade and know it won't be easy.

oh and I am skint if you could send me that pound......:yikes:

 

[Protilers]

We are all educating the chancers and the Diyers............as well as the tilers whom are new to the trade and want to excell.......that is the nature of an open forum!
the chancers will still take chances.....the diyers will still do research on the internet..... get the "real" answer....and get the job wrong (because they are not practiced!).............and the tilers that want to excell........

well, they will do good stuff in time......

all the best

but is bal ptb any good for plywood ? is the question i wouldnt of thought so but i don't know much about it is it a rapid flexible?

 

[Diamond Pool Finishers]

We the tilers still don't know and understand how flexible -flexible IS !!! where are the figures of expansion rate's that it can cope with on the bags ?, how flexi does it need to be to cope with the job in hand ? tests/science need to be done and tables published IMO ??

hi dave

ps , i know you know the difference between adhesives mate, its just this link explains about deformation etc , regards ed

this might be useful BAL Adhesives - Media Centre - What's the difference between ... S1 and S2?

 

[Perry]

for years its been standard practice to use rapid set on timber well it has been in my world as ordinary adhesive allows to much moisture into the timber ?

 

[Protilers]

I only ever fix with Rapid on floors......and PTB...will go over ply no problem IMO......but mirjam stated he was going to use a decoupler.....and I would do the same TBH......
but PTB "could" go over the 10mm bed that most decoupler makers reccommmend........so..........use a different adhesive or use SLC to level the floor prior to decoupling......

all the best

[Perry]

but is he going to fix the decoupler with ptb ? i have only ever used rapid ptb

 

[Mirjam]

after all I have read in this thread now, we decided to screw hardiebacker onto the plywood after all, ... don't want to risk anything.... That seems to be the safest method after all.. right?

 

[Protilers]

but is he going to fix the decoupler with ptb ? i have only ever used rapid ptb

good point PJC......went right over my head!!!!!!!!!!!....so........PTB is great stuff under certain conditions!!!!

I have a trowel supplied to me that is branded by a certain decoupler producer......and is reccommended for fixing thier product to the "substrate".......and it is 3mmx3mm square notch!.......

mirjam if you use PTB to fix your decoupler use a suitable trowel and ...........the floor should be flat by whatever means neccacary, before you apply the decoupler!

all the best

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.
