I've repainted my floorboards using Dulux Floorshield. (I do this every couple of years.) This time I used some CT1 sealant beforehand in some of the gaps between the boards and the paint is not drying very well, if at all, in these areas. (It's dry everywhere else.) From doing a bit of research it seems that you should not use alkyd paints on top of CT1... Does anyone have any suggestions for a way in which this could be sorted? Anything I could try? (Other than scraping all the CT1 out, which would be an absolute nightmare...) Thanks very much!
