How to mount a flat tv to a brick wall
In older houses, the load-bearing wall structures are often constructed of concrete or fired solid brick, in addition to which the wall may have been covered with thick plaster. In plastered walls, the anchoring of the wall mount of the flat screen TV must be attached to the load-bearing structure using plugs with a long neck or an 8 mm flanged concrete screw.
Sometimes, in order to determine the thickness of the plaster layer, it is necessary to make a test drill in an invisible place, such as behind a baseboard.
Based on the thickness of the plaster layer, either NAT 8 L or NAT 10 L nylon plugs with a long neck or the S-CS SS 8×75 concrete screw are chosen as the fastener.
The total thickness of the base of the stand and the plaster is 5 mm or less
Use a NAT 8 L nylon plug and a 4.5 to 6.0 mm diameter cap screw.
The total thickness of the base of the stand and the plaster is 30 mm or less
Use a NAT 10 L nylon plug and a 6.0-8.0 mm diameter cap screw.
If the diameter of the mounting holes in the base of the wall bracket is min. 8 mm
Concrete screw S-CSA can also be used for mounting the stand with plaster thicknesses of 0-25 mm
Installation of NAT 8 L and NAT 10 L nylon plugs:
Determine the correct position of the stand and mark the locations of the mounting holes with a pen on the mounting base. Use a roll gauge and a vatupass to make sure the TV comes straight. Drill a hole in the concrete using a good quality concrete drill bit and the impact function of the impact drill. Basic rule for drilling depth: plug length or concrete screw length (L) + 5 mm. Plug installation: Tap the plugs into the drill holes with a hammer and align the mounting holes on the stand. Use cap screws, the suitable length is the length of the plug (L) + the thickness of the base of the stand + 5 mm. Secure the stand base to the wall with screws.
Concrete screw installation:
Align the mounting holes on the stand and pre-install the concrete screws in place by hand twisting. The concrete screw is installed through the base of the scaffold using either a ring or socket wrench or an impact cordless screwdriver and a socket size of 10 mm suitable for the hexagon head (AV) of the concrete screw.
