1960' house (no asbestos) Working in 4 x 4 squares, spraying 1 - 2 coats of water and waiting for about 5-10 min. Getting this patches that reveal a green surface that feels like sheetrock. Am I scrapping to deep? If so, do I repair with putty or can I sand this down? Any advice (tools, methods) would be appreciated.https://ift.tt/2JbNKaB via /r/DIY https://ift.tt/2HlAQqg
