That's probably what, an extra 40% downstairs?

Mad fool that Mr DTM is, think of all that extra decorating

[TD]

Today is the first time I have looked at the before/after side by side:

Nothing wrong the first pic imo 

You will need those outside lights moved now as well, as they probably just light up the roof of the extension

Further work complete, lots of little internal jobs done and 125mm of floor insulation placed including a 25mm edge up stand.

Then a vapour barrier, under floor heating pipe (Pex-Al-Pex) and foam edger fitted, all ready for the screed.



Hearting manifold with the first two circuits connected, 3 Bar air pressure applied as an initial test, its now been sat at 4Bar for 48 hours with no pressure loss.

That is a cracking job, Mark, well done lad

[Varche]

Excellent.

What is the blue edge upstand for? insulation, a former for the concrete scree?. Does it come on a roll? I presume afterwards the "one inch" above floor level is overlapped by the bevel on the skirting board.  Never seen it before but it looks a good product.

[Marks DTM Calib]

Its a foam expansion strip, not hugely thick and does indeed come on a roll, has a strip of double sided tape on the back and a clear plastic film attached to the bottom which I have taped to the vapour barrier (vapour barrier also passes up behind this for good measure).

The edge insulation does not compress much hence the blue foam, once the screed is laid to height then everything gets trimmed flush to the floor level

And yes, covered by the 10mm dabs + 12.5mm plasterboard + 3mm skim plus +18mm skirting = 43.5mm where as the insulation total is circa 31-32mm

Very nice work Mark. That's a lot more room  I remember sitting in the kitchen  with you at the table fixing my old 2013 sat nav and stereo unit from my old blue elite.
...those were the days ..do miss the old girl and can't find one for love or money now. 

Hopefuly meet up with you soon next time around your neck of the woods

Hi Steve, good to see your still about   

Screed went down today, lovely job, very highly recommended!

[Entwood]

Looks good ...  did I read your other comment correctly .... 75 days to dry fully ??  How long before you can walk on it to do other jobs ??

[Marks DTM Calib]

2 days for traffic. 

Its the fully dry that takes 75 days so the time required before you can seal/cover the surface with a floor covering.

Which no one in the constuction industry ever pays any notice of.  Imagine newbuilds sitting dormant void of floor coverings for over two months

That's what triggered the question .. been watching a new estate going up near us, the houses are, literally, thrown together, and someone appears to be moving into one that was only started 6 weeks ago !! no idea when the floors were laid... walking the dog this morning I saw rolls of carpet going in !

A lot of new builds are not concrete floors, most are block and beam which have a light grout coating plus insulation, vapour barrier and 18mm chip board.

Others are concrete over insulation which is poured when at DPC level, by the time the walls are built, roof on, floors in , first/second fix, plastering and finish done, its pretty close to the no of days required.

You can get fast drying ones which can be covered in days but, they have issues with cracking etc plus they cost much more

That does look like a good job....no need for self levelling compound there, I thinks.

[STEMO]

You did pressure test the underfloor heating before you did that.....didn't you?
