Hi guys, few querries i've got with hardwall which i don't seem to get any clear answers on, so thought i'd see what peoples thoughts were on here
Firstly - To what thickness can we go with backing plasters, hardwall, bonding, browning and what implications does this have??
Secondly i have had probs in the past with floating and setting in the same day where the devil key shows thru the finish with the air's escaping in to the finish coats...this does go after a while but only after i've waited with it and gone over it a few more times....so will this go on its own without the need to keep trowling it up or i'm wondering what peoples thoughts are on floating up on one day and setting on another, or even floating and setting without the devil key, as i've been told by a few this is ok??
finally when is it best to set the float?? what signs are we looking for to know its the right time...up unitl now i've been waiting for it to firm up so the devil scrapes its key as opposed to dragging and collecting plaster on the float and leaving an otherwise thick devil key
finally, when going back to a house brick substrate where there could be a risk of efflorescence drawing thru (which i have had happen a few times) whats the best solution in elliminating this risk...should we be sealing with pva or using a salt retarder or somekind??
