JeffersLos Posted August 7, 2020 Share Posted August 7, 2020 How much weight can a hollow plasterboard wall bare, with regards to a heavy TV and wall attachment? We have a 32 inch TV that weighs 7kg without stand. And a 48 inch that weighs 10Kg without stand. The locations we want to put them are on a hollow plasterboard wall. They seem very heavy to attach using a wall mount. There are tall stands available, but we would prefer a solid wall mount. Is it safe to mount a 10Kg TV on the hollow plasterboard wall? TIA.

maxpower Posted August 7, 2020 Share Posted August 7, 2020 The shop that fitted a TV wall mount to my apartment drywall used four cavity fixings on each rail. It would take a lot of force to pull it off. Most of the load is vertical. 2 Link to comment Share on other sites More sharing options...
johng Posted August 7, 2020 Share Posted August 7, 2020 You should mount the bracket that holds the tv to the "stud work" that hold the plasterboards up, sometimes they are wood sometimes metal if not possible to mount directly to the stud work then you need to spread the weight over as large a surface area as possible I used that method once by cutting a piece of 10 mm plywood/particleboard to slightly under the tv size ( about 50 inch tv) fix the plywood to the wall using 10 or more plasterboard anchors around the outer edges (they have butterfly expander wings not normal screws) then use normal (but large and as many as possible) screws to mount the tv bracket to the plywood plasterboard sandwich...test before hanging the tv ???? I tested by pulling vertically down on the tv bracket as close to the wall as possible so as to not produce a pulling force....it took my whole weight >60 kgs that was static weight obviously not jumping up and down on it. 2 Link to comment Share on other sites More sharing options...

canopy Posted August 7, 2020 Share Posted August 7, 2020 If a fastener does not specify how much weight it can handle on the package, don't buy it. Get one that can support the right weight. Also the thickness of plasterboard will be important. Everything You Need to Know About Wall Plugs 1 Link to comment Share on other sites More sharing options...
JeffersLos Posted August 7, 2020 Author Share Posted August 7, 2020 We went for the lazy option and bought one of these: https://www.lazada.co.th/catalog/?spm=a2o4m.home.search.6.1814719c9uWmtq&q=TV stand&_keyori=ss&from=search_history&sugg=TV stand_5_1 There's a wooden dresser in front of it, so thankfully the ghastliness is mostly hidden. 1 Link to comment Share on other sites More sharing options...
wobblyjohn Posted August 7, 2020 Share Posted August 7, 2020 (edited) Tap the wall till you find the wood behind the plasterboard and if you can put screws through there where you hear a hollow sound put a butterfly clip Edited August 7, 2020 by wobblyjohn 1 Link to comment Share on other sites More sharing options...

But the plasterboard is mounted on something...usually aluminum or steel lattice...you need to mount your brackets on whatever supports the plaster 1 Link to comment Share on other sites More sharing options...

They do use wood but its not the best choice in many cases as the insects love it, also seems to be a more expensive option than steel/metal... I'm always bemused at those wooden/plasterboard American houses why keep building them in hurricane zones...just get blown away all the time ????

Plasterboard is not a traditional building material in Thailand and wood studs aren't used for it now, nor was it ever. There's probably as many igloos in Thailand as there are houses made of wood 2x4's. Edited August 9, 2020 by canopy Link to comment Share on other sites More sharing options...
