We would like to thank our customer very much, who, because he found very little information on the Internet, he decided to create the visual documentation of his construction project, and also gave a lot of information on the procedure and explained what was done and why. Please read our customer's documentation now and get inspired for your own projects. We are very curious how do your projects look like. I planned to hang my TV on the wall for a long time.
I mounted 18 mm OSB boards with tongue and groove onto profiles screwed to the YTONG wall. As a TV holder I took an extendable holder, because thanks to it, it would be possibile to adjust the depth later once the stones are glued.
I screwed the holder with special YTONG anchors from Fischer. For sure you are wondering why I got started from the top. To prevent tiles from sliding down, I worked with supports.
If a little glue spilled nothing stays on the stones.
I cut the stones with a standard foxtail hand saw. I didn't mount them right up to the wall, but left a gap.
I mounted LED tape in a way that allows me replacing it in the future. Then I primed the tiles to secure them from getting dusty later.
You must be careful there - secure the walls around, so that primer won't make a stains everywhere.
You can't see it later after TV montage, but I prefer that way ;-) Then I installed the 65'' TV and attached a DIY Ambilight to it, which is controlled via Raspberry. Therefore, as written above, I sawed tiles by hand, which is really quick.
If you have any further questions, please do not hesitate to contact me directly.
