I need to fill some chases & I can’t buy Thistle bonding 60 from anywhere.
Can I just use Thistle bonding & build up
the layers?
Or any other recommendations?

If you sling a hand full of cement in your bonding mix it goes off a lot faster, plasters at work do it👍

I used a sand/cement render 4:1 to fill in the old massive (8 inch?) boiler flue. Came out ok.

Is it for those heating pipes Rocky?
If it is maybe you could screw some sort of cement boarding over them then skim over it?
I'm thinking that the continuous expansion and contraction of those pipes is going to crack any cememt based rendering product if that is used..

What do they do in new houses I wonder? Not all the walls are stud.

I need to wrap them but don’t want any problems in the future. Maybe I can cut more plaster off & plug/screw board to the wall then skim? |

I think that they're all "dot and dab" these days with the pipes/electrics in the d&d space - I don't really know though because I don't work on any new builds. However, we all know someone who does....and I'm sure he'll be along soon to put us right  . |

I have once used expanding foam for a similar issue then cut the foam back with a chisel then just used a multipurpose finish but my preferred method is to manufacture a void in a suitable spot.
