"Any painter worth his salt would know you never use bonding of any kind prior to painting with water based paints especially exterior painting. Bonding is to enable porous surfaces to be sealed and to provide grip for plaster products . As a painter to trade 30yrs and semi skilled plasterer you never bond especially if applied on exterior surfaces and then painted over it will take a winter of cold damp frosty nights and days and come summertime your lovely prep and bonding will blow your paint right off the walls."
"I have used this several times for priming the walls prior to plastering and I must say that this is the best I have ever used, I tried the Evo-stick brand on this batch of plastering, yes it works but not so user friendly as this stuff. Great for wood working etc, all in all it nmight be a little bit more money and you have to buy a bigger tub, but well worth it."
