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.
