Hi

[yes]

Need a little info,

I'm using fiba tape on flats and paper on external, but all i'v got is ready mix tubs. Is it true that using ready-mix with fiba, may crack?

cheers

Oh dear
Dont use ready mix cement with fiba, use fast set joint filler 1st then cement but I'd bin the ready mix as its too hard to sand, get the bags
Paper on external? Surely you mean internal paper tape?
Welcome to the forum BTW

i always use a fast set on fiba tape,much stronger than top coat mate.
