Got what we think is a wattle ceiling. Removed the artex from the original skim and got a smooth finish. High spots left are under 1mm. The appearance of the ceiling is marred by reminants of artex on the low spots. Any comments on: Currently suitability of the surface. Wash with mildly soapy water. Dry for a few days. PVA coat. Reskim. Could keep scraping but am trying to preserve ceiling integrity. Some small movement / flex when pushed right now, but not enough to suggest ata danger of falling to my inexperienced soul.
