Filler for chases

[Si_]

Can anybody recommend a filler for chases and filling of old socket recesses up to 70mm? Other than the ready-to-use fillers, which work OK but are hugely expensive, I haven't been able to find anything. I was recommended Easifill 60 but on receiving it and and reading the package I see it's only suitable for layering up to 5mm, which is completely useless to me.

SBR the masonry and give that an hour to dry.
Buy a bag of bonding plaster and a bag of multi finish.
Fill water to just under half a black bucket.
Using both hands drop two loads off bonding in water..
Add multi finish to thicken up.
Fill chases.
We call it a magic mix.
Use a damp sponge to keep edges tidy.
Splash water on and smooth over as its setting.
Will take 4 days to dry.
You can sand and use decorators filler to finish off

Quick dry bonding followed by standard filler to finish .

I've always used Thistle.

I filled some chases and some old backbones (now unused!) the other day. For the first time, I bought some bonding plaster - it's a total revelation. Easy to mix and apply, and you can slap in in very thick.

I was all set to get some EasiFill 60, but had a several-years-old tub of Wickes ready-mixed equivalent, which I couldn't justify wasting. That stuff also worked well as a thing skim on top of the bonding.
