Vapour barrier

Recommended Posts

I am sure many people don't do any prep on liquid screeds - certainly not many developers - but they should be sanded and primed if you are tiling.

You don't need to do any prep before you tile it and if the screeder is good it is smooth and flat enough to lay any flooring (LVT etc) whereas sometimes you can get little ripples and bubbles with liquid.

He said it would be more level with sand & cement

Just make sure that your UFH pipes are very well secured so they don't lift / bend and end up poking through the top of the screed.

That picture brings back memories from 2 years ago....  looks like a neat job.  Have you left enough of the dpm to tape your airtight membrane onto?

 

As @Onoff says make sure you pin the ufh pipes down well, our screeders wanted extra to protect against the pipe lifting.

No dpm ; just vapour barrier to go ontop

Emergency question !

 

i assumed the vapour barrier would have a ‘ install this side facing up ‘ ( like roofing barrier ) . But it doesn’t - so it doesn’t matter ? Seems strange

First sheet down .

Pushed it into the corners .

Can see though when they pour the screed suddenly causing the plastic to slip and slide inwards .
