I wanted that exact industrial look for my home office to break up the boring white walls. After browsing a few decor forums, I decided to take a chance on a raw concrete design from https://muralas.co.uk/ and it looks remarkably realistic. The material from Muralas has a completely flat, matte finish, which means daylight doesn’t bounce off it artificially, giving it a proper textured appearance. Everyone who sees my office backdrop on video calls genuinely thinks it’s a real poured concrete wall. It’s an excellent, hassle-free alternative to messy plastering work.
