I would knock off any loose paint and do your scraping and any sanding before you wash the house down.
By washing the house down, I'm assuming that you mean pressure washing. If so, that phase is over with. It appears that portions of the several of the brick walls years ago were retucked up to a height of approximately 7 feet from the ground. Afterwards, these sections were repainted with who knows what - but anyway a red color attempting to match up what was already there. This is the stuff that is peeling off down to the bare brick post pressure washer episode.
When the paint first began peeling off as I was blasting away, my first thought was 'Oh crap', I don't want this to happen. But I'm sure it is for the best. I'm assuming that you would want to remove any paint that is not latched on securely.
Once, I get done with the scraping and retucking - there is a bunch of that to do - I'll wash the building down one more time with a hose then prime where I have scraped and/or retucked. At least that is the plan for now.
Snip..
I would follow up with the high build loxon to get you the thickness to build out any imperfections the brick may have. there are other ways of doing it, so take this as my opinion if i was doing it.
I hadn't considered the high build loxon as a follow up step. I may pass on that step. This
is a rental unit - an old 3 story row house in a series of row house that all pretty are clones. The two apartments have been completely renovated. I'm hoping that if I do maybe not an 'A' job (that would be one where say I planned on living there myself for 20 years or something) - but a 'B+' job, then some of these other what I call slum landlords might consider doing the same thing. Probably not but at least I can hope. :yes:
Thanks for your help.
