I have some electrical chases to fill and am planning to use Gyproc Easy
fill 60 (unless there are better suggestions)

However the instructions say

— Second coat can be applied between
140 - 280 minutes after initial coat

Does this mean a minimum of 140-280 for any final touching up coats, ie
I can fill the bulk of the channels on day one and come back on day 2
for a final skim, if needed.

The wording above puts doubt in my mind as to whether the second coat
would bond if you left it 24 hours rather than 280 minutes.

I doubt there's anything that clever going on with a gypsum based
filler :-)

Expect the wording relates to first coat initial setting time,
possibly dependent on depth & ambient temperature?

Easy Fill is designed for fairly thin application and if applied thick like in a chase it takes forever to set. To be honest I do do not see why people try to avoid the obvious and perfect solution which is to use plaster. A ground coat will take approx. 30 mins to stiffen enough for a finishing coat to be applied finished and done with in a day.

Bollocks.

bulk filling and finishing, ideal for repairs, chasing in and
patching. This product has a working time of just 60 minutes and
any second coat can be applied in 140 minutes. High ..."

Thanks All. I will give it a go.

Just keep a bag of out-of-date Wickes fine surface filler to
hand. Sets in few minutes and unlike gypsum plaster it can be
sanded smooth.

The fact that once out of date it sets in a few minutes, strongly
suggests to me there's gypsum in it too...

In article <piknpn$1ohf$1...@gioia.aioe.org>,

A bag of out-of-date finish coat works very well.
Add a very little PVA to the first coat to make bonding coat
plaster (or use out of date bonding coat if you have it), and
use the finish coat as-is to polish off the top of the chase.

The first (thick) coat will crack which doesn't matter, but
leave it 2mm below the surrounding surface so you can apply a
thin finish coat which won't crack.
