I’m convinced that the technique of using Wainscot was invented by some poor sap who was repainting a house and discovered that the original owner hung wallpaper directly over sheetrock without first priming the surface (sealing, sizing, whatever you want to call it).
We bought a Wagner steamer to take off the red & pink pattern wallpaper in our dining nook and kitchen so we can paint. It’s slow going! I got to the bar area and Chris said “why don’t we put up white beadboard paneling under there, it will match the cabinets? I said great idea! Why don’t we just Wainscot the whole room!
