Decorative panels are not structural. A TV bracket screwed only into WPC or MDF will pull out over time. We mark the bracket position before the panels go up, add a solid timber block behind the panel line at that spot, and use fixings long enough to pass through the panel and the backing into the wall.
Floating units are heavier than they look once they are full of consoles and a soundbar. We hang them on a concealed steel rail or heavy brackets fixed into concrete or studs. On gypsum walls without studs in the right place, we add backing or recommend a unit with legs.
Before drilling into any wall, we follow the process set out in safe drilling on concrete, gypsum, marble and brick walls in Dubai. For the TV itself, see TV wall mounting in Dubai, and for audio, soundbar and home theater mounting.
