My pool body has been stripped of the old plaster via jackhammer. It's still got some small left over chips and dust in it. I was curious as to what is the standard prep procedure prior to the PB applying the plaster. Does he vacuum out loose debris and dust, or hose everything to the deep and and then suck out the collection of debris? Just wanting to know what is the SOP to ensure plaster has a strong bond (or what would be considered a sub-standard prep at this stage)
Searched and found a lot about poor plastering technique, ie troweling with too much water, using too much calcium chloride...but couldn't find anything about the prep. Thanks.
