Is it the ultimate DND system , does anyone prefer to Addy ?
 
No takers so assume its not a common choice , got a two room extension to do with the builder I work with , he's not a fan , I'm looking to do all walls not just external ( 9' single ) . as usual I complicate things and will be using a combination of Addy and foam , Addy for fixing areas ( kitchen cupboards , skirtings etc ) foam the rest ,

anyone else do this , perhaps you learnt this on a course :)
 
I have never used it... I dont get out it works and is better either but I am open to new ideas and innovation

We used it recently to hold the ends of a couple of boards on to steels, worked ok.
If you're intending on using on walls instead of adhesive you're two sandwiches short of a picnic. Not that we needed that confirming anyway you loon.
 
You need really good flat plumb walls with foam. Dab allows you to make adjustments more easily as you get a bit of resistance when tapping the boards true.
I sometimes use foam for a bit of patching as it does stick really well and can’t usually be arsed to mix up a bit of dab. Good for sticking board to steels too as J R Hartley has mentioned.

I'm getting an undertone sense of curiosity and admiration from your post , but how did you get on sticking with foam , was it in the spec or out of choice

Its better on a couple of things, thermal bridging and the fuss of transporting and mixing Addy
 
Havagojo said:
So forget the hassle of dabbing with it how do you rate its longterm performance , any limitations over Addy ?

It's a bit difficult to give you a long-term performance report seeing as we only used it about three weeks ago. Up til now the house hasn't collapsed if that helps.
You wouldn't ever catch me sticking a board to a wall with it though.
 
Have another beer before doing any calculation, always helps , not necessarily getting the right answer , but it helps

I can easy get six bags lol.

To use that the walls would need to be absolutely cock on.

Do you mean six boards , perhaps you shouldn't have had those beers JJ
OK so 1 bag= £9 or 2 cans = £12 , so i use 1 bag and usually get 2 boards on an average refurb ( I'm a bit fussy ) so its 50p/ m2 ,
Alright so far ?
How long does the transport , getting water , mixing the Addy and dabbing the wall cost compare in time to spray the foam , spray the wall ?

Yeah sorry 6 boards from a bag easy

So how many boards on a good day ?

We get about two sheets of board fitted with a bag of adhesive, the correct coverage.
Basically around 1/5th of the board board area has solid contact with the blockwork with an average 10mm gap between the back of the board and the blocks. This is industry spec. Can this be achieved when using foam? Is the foam actually cleared for use on properly spec'ed new work?
IMHO it is, at best, a handy problem solver. Nothing more.
