I’ve just spent the last two days prepping and painting our dark wood panelling in the hall. The final coat was Dulux Once eggshell paint in white. I painted it over 16 hours ago and have come downstairs to find the finish is still very shiny. Has anyone else had this problem? I was looking a for a matt finish and this looks more like gloss. We used Zinsser BIN primer underneath. Do I need to buy another paint to go over it to get a less shiny look?
