Watched Build new home in the Country prog last night, doing up a

Boy, the presenter has been learning off Kevin McCloud - doom before
the adverts etc, oh what a beautiful house at the end, looking
supsiciously "dressed" for the program.
Anyway, they pumped in some totally liquid screen over underfloor
heating pipes. This seemed so much easier than the dry screed method.
What is this liquid screed ? Is it expensive. Talk about self-
levelling !
Just make sure theres no holes - I can envision the whole expensive
lot disappearing into the ground.

F Ball Stopgap 300 *can* be used like that (pumped) - I noticed in the
datasheet when I was using it (bagged and whisk mixed in my case). I
suspect though, that you'd need a variant, perhaps Stopgap 600 which can be
applied much thicker (300 is 15-20mm, 600 is 50mm).

There are probably loads of variations of that sort of product.

Expensive? I had wondered that. Stopgap 300 is about £12-14+VAT/25kg bag +
you need primer. No idea what 600 costs.

That will cover 5m2 at 3mm thick (most do). So let's say 50m2 floor (I
didn't see the programme) and 50mm thick - that's about 170 bags so well
over 2000 quid in material.

No idea what pump (and operator?) would cost.

I expect whatever compound they used might have been cheaper, bulked out
with fine aggregate or at least cheaper in bulk, but the plant/contractor
hire would take that part of the job to many 1000's I would guess, wildly..

OTOH, compared to dry screeding, it's much less labour intensive.

Pity they don;t have some more facts in that programme...

Yep, its kind of lifestyle as well.
I notice that every time they mention jobs, the couple in the program
always own a company or have just sold a company. Last nights chap
"had a small firm of solicitors".
I wonder what these guys staff think of their rich boss going on some
mad building project.
Plenty of rich chaps on this group of course (some in hiding ?) I'm
not one of them !
