Your flat contains different wall types, and each one demands a specific anchoring approach. Guessing wrong strips the bolts out of the wall, often damaging the plaster beyond a simple patch job.

Reinforced concrete walls form the load-bearing structure of your block. These walls consist of high-density concrete poured around steel reinforcement bars. A wall mount hanger rod anchored into concrete can support substantial weight because the concrete grips expansion anchors with tremendous force. The challenge lies in the drilling. You need a rotary hammer drill with a tungsten carbide masonry bit, and you also need a rebar detector because hitting a steel bar stops your bit cold and leaves you repositioning the entire bracket assembly.

Brick partition walls appear in older HDB buildings, typically those completed before the mid-1990s. Solid clay bricks offer decent holding power when you drill into the brick body, but the mortar joints between bricks crumble under anchor expansion pressure. Mark your hole positions to land in brick, not mortar, and use sleeve anchors rated for masonry.

Drywall or plasterboard partition walls dominate newer flats and rooms added during renovation. These walls consist of gypsum boards screwed onto light-gauge metal frames. The board itself holds nothing heavier than a framed photo. A wall mount hanger rod carrying a heavy load cannot anchor into drywall alone. You must locate the metal studs behind the board and drive your mounting screws through the plaster into the stud.

A common Singapore-specific issue involves false walls built to conceal household shelter doors or structural columns. These walls look like concrete but consist of a thin render over metal mesh or plasterboard. Tapping on the surface produces a hollow sound, a dead giveaway that you must find the supporting frame behind it before proceeding.
