TV wall mount but crumbly walls

Postby Roberto154 » Wed Jul 13, 2022 11:55 am

Hi
Trying to mount a 49inch TV bracket.

The walls when drilled produce black dust and just crumble. Solid concrete blocks probably.
Is there a recommended drill bit to combat this issue to fix securely?
thanks

Hi roberto154,
You probably have a wall built with breeze blocks. Try using an oversize wall plug - one that needs hammering into the hole. If this doesn’t work you will have to use anchor bolts set in the holes using an anchorfix resin. Use a straw to blow dust out of the drilled hole.
