do it alot.....upstair bedroom that are dry as chuff, multi has blown ( had about 5 of them on 1 estate in walden), can,t throw lots of water at it as its upstairs..could pva it a million times or slightly wet then tight coat 1 coat then skim,,,,,,,,,,erm chases use it alot there...patch up in general...moody brick background as it set like stone......... why else .....lol.......dont like the finish of it when used by itself ( this is hand applied heard threw a machine it alot better).........erm..has really low suction......im weird like that !.......why the hell not? should really be your question Gary ;o)
 
oowww it also hold back really high suction and makes it managable.....im gonna stop now........im being a bellend lol.....i use it on alot of old brick jobs in walden , but hardly ever use it as an all in one plaster if i was honest.
 
you should only use bonding on low suction, if you going onto old brick ot blocks use browning or hardwall but treat the area first with a light pva coat, you dont want to kill the suction. if you think there may be problems with damp then only use sand and cement dont use bonding or hardwall where damp is a concern.
 
why dont people learn to deal with suction, rather than trying to control it. the gang that taught me, often would not skim the browning on a friday afternoon,( not enough time) so it was skimmed on monday, use to suck like mad. took me a while to learn this, trowel it up as you lay it on, and it never cracked once. mind you it was carlite finish. multi's ok when its white dry aswell.
 
For bonding and hardwall for skiming same day obviously straight on with the muilti for next day or couple days after i just wet down the walls with pure water and skim never had any problems,OK sometimes you gotto be a bit quicker but i was told this was the correct way for the plaster to bond properly to each other.
 
while your on this topic, on this rending job im looking at the old brick work is reali reali dry do you think i should just soak with water or apply sbr or pva? ta
 
Just wet it down making sure it is dust free try adding some fibres to your scratch coat and a little sbr works a treat havent had any come backs since we have gone over to this method.
 
let the plasterer decide,.....hosepipe comes to mind. more importantly as spunky said, what do you think ?
