Styrofoam decorative ceiling tiles are lightweight, easy to install and virtually maintenance free. Easily glue up to your existing ceiling or wall surface to add a touch of elegance to any room in your home, office or place of business. Can be painted or faux finished with any water based paint for a unique and custom look. Also great for craft projects and DIY photo backdrops!
I was thinking of something like this, except patches of tiles, rather than entirely covered, for our retaining wall. The rest would be white plaster. Partly inspired by Parc Guel, partly by a friend putting 4 or 5 handpainted tiles on her garden wall.
