it used to say 2 1/2 hours on board finish and 3 hours on multi...
now it just says 1.5 hours on each, but thats one coat innit....
let the first coat hazel off and mix fresh for the top coat and lay it on thickish and your still lookin at 3 hours a set...
this warm weather makes a difference mate and I'm led to believe theres such thing as a winter and summer batch from british gypsum, as in the amount of retarder in it..... ive had the odd bag set up like quick smart on a 10m ceiling lately and others hang for ages... just a case of feeling every set...
hey ho, thats the nature of the game though...
anyone know a way of knocking up a 1 coat mix for chases that sets in 10 minutes
without shrinking like a ballsack in an icebucket?
ive been trying allsorts of concoctions like 1 bonding 3 finish, 2 cement... goes off quick, pva the background and it doesnt crack but what it does do is shrink back from the edges of the chase... :
so far the best result ive had is bond out the chases dry using bonding+quickcem, 20 minutes @ around 10mm depth and skim it with multi...
problems arise when the bonding is deep like on these 'no fines' concrete houses - the chases can be 3" deep sometimes...
