I get a call about once a fortnight from someone whose 6 kg framed print just took a chunk of plasterboard off the wall on its way to the floor. The frame’s bent, the glass is in pieces on the floorboards, and the picture hook is still attached to a triangle of Gyprock dangling from the wire. Nine times out of ten it’s a brick-veneer wall, and they’ve used a hook rated for “drywall up to 10 kg.” That rating is for solid drywall over a stud — not Gyprock floating over a 50 mm cavity.

Brick veneer is the dominant wall type in Australian homes built between 1950 and now. The outside skin is brick. Behind that brick is a 50 mm cavity (for ventilation and waterproofing). Behind the cavity is a timber stud frame at 450 or 600 mm centres. Then 10 mm Gyprock on the inside. When you drill into a “brick wall” inside an Aussie home, you usually go through Gyprock, hit air, then hit brick. That cavity is the killer.

So if you want to hang a 15 kg painting or a heavy mirror on brick veneer, you’ve got two real options: fix to the timber stud (best), or use a frame fixing or cavity anchor that grips the brick across the cavity. Here’s how I do it.

What you’ll need

Stud finder with deep-scan mode (Bosch GMS 120, Stanley FatMax IntelliSensor)
Cordless drill (18V, hammer-capable for masonry)
Masonry bit set 5 mm to 10 mm — Bosch CYL-5 or Makita
4 mm wood drill bit for stud fixings
Ramset DynaBolt 6.5 mm sleeve anchors (for masonry-only fix) OR Ramset frame anchors 10×100 mm (for cavity-spanning fix)
14g x 65 mm Bugle batten screws if fixing to studs
Spirit level (300 mm)
Pencil, masking tape
Vacuum cleaner with brush attachment

Step 1: Identify what wall you’re actually drilling into

Tap the wall. Hollow knock = Gyprock with a cavity behind it (brick veneer or stud-frame internal). Solid thud = solid brick or double-brick. If hollow, you’re brick veneer; do the rest of this article. If solid, you’re double-brick (older Aussie homes, pre-1950 mostly) and any DynaBolt straight in will work.

Quick check: drill a 3 mm pilot hole. If you punch through after 12 mm of soft material and feel air, brick veneer confirmed. If you hit hard resistance after 10 mm, double brick.

Step 2: Find the timber stud first — that’s the gold standard

If a stud is anywhere within 200 mm of where you want to hang the artwork, fix to the stud. Use the deep-scan mode on the stud finder; cheap finders read the brick behind as “stud” and lie. Cross-check by drilling a 3 mm pilot — into a stud you’ll get timber dust. Into Gyprock-then-cavity you’ll feel the bit punch through into nothing.

Stud-fixed: 14g x 65 mm batten screw, pre-drilled 4 mm, will hold 50+ kg easily. Done. The cavity stops mattering.

Step 3: If no stud is convenient, decide between brick fix or frame fix

Two real options:

DynaBolt straight into the brick — punch through Gyprock, drill into brick, set anchor in brick. Pros: rock solid, brick is doing the work. Cons: leaves a permanent hole; if you ever take the artwork down, the bolt is permanent.
Ramset frame anchor spanning the cavity — a long bolt with a sleeve that expands inside the brick AFTER passing through the Gyprock and cavity. Pros: the wall surface holds the artwork flat against the Gyprock, the brick takes the load. This is the one I usually use.

Step 4: Mark out and tape

Hold the artwork up where it’ll live. Mark the top corners with pencil. Step back, level it. Now mark where each fixing point will be — for a heavy painting, two fixings 600 mm apart on the back wire are far better than one in the middle.

Stick a 50 mm strip of masking tape over each drill point. Tape stops the drill skating, stops Gyprock paper tearing on bit exit, and gives you a clear pencil mark.

Step 5: Drill through the Gyprock first, on rotary mode only

Important: don’t go into hammer mode while you’re still in Gyprock or you’ll blow the paper face out into a 30 mm crater. Use rotary mode, 5 mm bit (for a 6.5 mm DynaBolt) or 10 mm bit (for a 10 mm frame anchor). Drill through the 10 mm of Gyprock, feel the punch-through into the cavity, stop.

Step 6: Switch to hammer mode for the brick

Now switch the drill to hammer + rotary. Push the bit through the cavity until it touches brick. Drill into the brick to a depth of 65 mm (for a DynaBolt 6.5×65) or 75 mm (for a frame anchor). Mark the depth on the bit with masking tape so you don’t go too deep.

Vacuum the hole. Brick dust mixed with sleeve anchors = anchor doesn’t grip. I run the vacuum brush right over the hole and drill another 5 mm to clear the dust at the back.

Step 7: Set the anchor properly

For a DynaBolt: tap the anchor in with a hammer until the head is flush with the Gyprock. Tighten with a socket — you’ll feel it bite at about 6-8 turns. Stop tightening when you feel hard resistance; over-tightening crushes the brick or strips the sleeve.

For a frame anchor: thread the bolt through the artwork bracket, push through the wall hole, tighten. The sleeve expands behind the brick.

Step 8: Don’t trust “no-drill” hooks for anything over 5 kg on brick veneer

The 3M Command strips and the Hercules hooks at Bunnings are fine for posters and unframed canvas. But anything with glass, anything in a heavy frame — they fail. The adhesive lets go in summer when the wall heats up. I’ve patched too many Gyprock holes from failed Command strips.

Rule of thumb on brick veneer: under 3 kg, hook into Gyprock with a screw-in hook (no fancy anchor needed). 3-10 kg, plastic Gyprock anchor with a screw — but only if you must, and centred on the Gyprock, not near edges. Over 10 kg, stud or brick fixing as above.

Step 9: Hang, level, step back, sleep on it

Once the bolts are set, hang the artwork, level it, step back. Push it gently both ways to feel for any movement. Walk away. Come back the next day and check it’s still level — if a fixing was iffy it’ll have crept overnight.

Step 10: Patch protocol if you ever take it down

DynaBolts and frame anchors leave 8-10 mm holes. To patch: snap the bolt off flush with the Gyprock (for DynaBolt — leave the sleeve in the brick, you’re not getting it out), fill the Gyprock-side hole with Selleys No More Gaps in ‘paintable white,’ sand flush after 24 hours, paint. Looks invisible.

Step 11: Know the weight limits and double up if uncertain

Single fixings have weight limits but real-world performance depends on installation quality. Rule of thumb on what I trust:

Single 14g x 65 mm screw into a stud: 30 kg
Two 14g screws into a stud, 200 mm apart: 70 kg
Single Ramset DynaBolt 6.5 mm in solid brick: 40 kg
Two DynaBolts spread across two bricks: 100 kg
Frame anchor 10 mm spanning cavity to brick: 60 kg single, 130 kg paired

For a heavy mirror over a fireplace, or a 3-piece artwork that’s effectively one heavy load, always double up. Two fixings 600 mm apart is geometrically far stronger than one in the centre and stops any rotation if one anchor creeps.

Step 12: Photograph the install for the next person

I take a photo of where every fixing is, with a tape measure visible for scale, and I email it to the homeowner. Sounds OCD. Saves 30 minutes the next time someone wants to reposition or remove the artwork — they know exactly where the fixings are without re-finding everything.

The Mick rule

The Mick rule for brick veneer is: find a stud or fix to the brick — never trust the Gyprock alone. The Gyprock is a 10 mm sheet of paper-faced gypsum hanging in space. It’s not structural. Anything heavy needs to land its weight on either the timber frame behind it or the brick behind the cavity. Get that right and your artwork will outlive the house.
