My basement walls are full of efflorescence and peeling paint. I've scraped off as much as I can with a thin scraper and some use of a wire brush. It looks fairly good but still some areas near the base of the wall have remnants of efflorescence.
Wondering if the Drylok etch will take off the paint and some areas of efflorescence and if it's necessary? I've already purchased the Drylok latex masonry paint and am anxious to use it.
