i'm going to give a bit of dot and dab a go in my house and have a couple of questions.
pva - been told that as its a brick wall thats previously been plastered and stripped bare it needs pva first or it wont stick, yet other posts here say you dont, is there a definitive guide as to when to pva and when you dont have to.
if you do, should the pva be dry or tacky when you dot and dab.
found another post that says not to d&D on external walls with no cavity- why is this? i need to fasten some insulated board to these walls but my wall is a 9 inch double brick wall.
thanks in advance.
