Hallway - bi susbstrate issue

[cam_low]

Hi peeps, just a quick question to advise on the transition of floorboards to concrete.

What would you advise ?

Im thinking rip up the floor boards and ply with correct size, then Duralbase through the both rooms.

Any other options ?

cheers peeps.

PS the tiles are Henley Cool | Topps Tiles

So, would you not do something at the transition where the two substrates met.? and nice link back to who you work for now LOL.

obviously an expansion gap come on now Dave...

Well i know and you know..🙂.. but you asked..

I've done this before with an uncoupling membrane and not had a problem, the other choice is to go over the whole floor with a cement board.

Yes and I understand the need to rip the pee for my choice of employer but would you rather it be me there or some other numpty !!!! A job was needed as my rent is £850 a month before bills !!!

Things are looking up and progressing, my contacts book is growing, weirdly this job is for the woman who used to own the house im renting. She came in and I served them and as things progressed it came out she just sold the one i'm in !!!

Weird eh !

 

[DHTiling]

Yep.. Lifes like that.

I was researching to see how many people had successfull installations with screwed boards, primed and decoupled. Im sure it would be fine but would like confirmation !

I have minimal time and the screwing with plugs and screws in the kitchen will be time consuming.

Not a huge difference time wise.
Save time by spraying your primer on the floor, and roll over with a paint roller, this is much quicker than applying it with a sponge etc.
Both methods ideally would need to be left overnight to cure properly even with rapid set.
The overboarding method i would say is a more secure system, but you introduce more height gain issues.

Screwing with plugs and screws.. you thinking of overboarding the screed part as well.?

 

[bugs183]

Me or Cam???
I'd give the customer the choice it how they want me to approach the job.
If i was boarding and fix the boards into adhesive on each substrate and screw only the wood side, if you have to screw into the concrete there is something very wrong with the sub floor.

I would have to to keep the height levels the same.

Which method would you go with Dave ?

I would have to to keep the height levels the same.

Which method would you go with Dave ?

Remove floor boards and replace with ply (min22mm) if required slc screed section to that height, insert expansion joint and tile.. using correct adhesive for either side , if you want belt and braces approach then de-couple.

 

[bugs183]

That methods fine as long as the line of the expansion joint is straight and can be set out in bond with the tiles.
I'd still use a decoupling membrane, to as least 400mm onto the concrete from the intersection between the two substrates.
