TV Mounting Question
Hi everyone. I wasn’t sure if this was the perfect thread for this question, but the TV mounting thread seemed very quiet. I recently mounted a TV above our fire place mantle. And before people ask, it’s really the only place one can go in our house because of the lay out. I’ve mounted many before, even above fire places, but was usually dry wall with studs. Found out here that there’s drywall over a masonry wall, with about 1/2” air gap in between. The central portion, and much of where I drilled seemed to be cinder block, which I saw on the opposite wall in the house in our attic. Was able to drill through what I assume was furring strips and into cinder block for three of the tapcon screws I used, and two others just through dry wall and block, just didn’t fasten those super tight. The drill bit fell into a void which I assume was the central portion of the block. But for one of those screws through the wood, instead of grey dust the whole time, it turned into black dust but was solid the whole time without the void. Does anybody know why the dust would be black? I was worried initially that I some how drilled into the flue, but don’t know how that’s possible. Especially since I only drilled the length of the screws (2.75”), and there’s about an inch of dry wall and empty space first. Just curious if anybody has any wisdom. I’m not worried about the strength of the mount,with several solid fixations for a 47lb TV. The fire place isn’t in use right now cause it needs a lot of work to get up to use, just don’t want to make it worse, though there are several holes into the block from the previous owners that need to get fixed. Sorry for the weirdly long post. submitted by /u/PseudoImprovement [link] [comments]
